MongoDB Named as a Leader in The Forrester Wave™: Translytical Data Platforms, Q4 2022

In The Forrester Wave™: Translytical Data Platforms, Q4 2022, translytical data platforms are described by Forrester as being “designed to support transactional, operational, and analytical workloads without sacrificing data integrity, performance, and analytics scale.” Characterized as next-generation data platforms, the Forrester report further notes that “Adoption of these platforms continues to grow strongly to support new and emerging business cases, including real-time integrated insights, scalable microservices, machine learning (ML), streaming analytics, and extreme transaction processing.” To help users understand this emerging technology landscape, Forrester published its previous Translytical Data Platforms Wave back in 2019. Three years on, Forrester has named MongoDB as a Leader in its latest Translytical Data Platforms Wave. We believe MongoDB was named a Leader in this report due to the R&D investments made in further building out capabilities in MongoDB Atlas , our multi-cloud developer data platform. These investments were driven by the demands of the developer communities we work with day-in, day-out. You told us how you struggle to bring together all of the data infrastructure needed to power modern digital experiences – from transactional databases to analytics processing, full-text search, and streaming. This is exactly what our developer data platform offers. It provides an elegant, integrated, and fully-managed data architecture accessed via a unified set of APIs. With MongoDB Atlas, developers are more productive, they ship code faster and improve it more frequently. Translytics and the Rise of Application-Driven Analytics Translytics is part of an important shift that we at MongoDB call application-driven analytics . By building smarter apps and increasing the speed of business insights, application-driven analytics gives you the opportunity to out-innovate your competitors and improve efficiency. To do this you can no longer rely only on copying data out of operational systems into separate analytics stores. Moving data takes time and creates too much separation between application events and actions. Instead, analytics processing has to be “shifted left” to the source of your data – to the applications themselves. This is the shift MongoDB calls application-driven analytics . It’s a shift that impacts both the skills and the technologies developers and analytics teams use every day. This is why understanding the technology landscape is so important. Overall, MongoDB is good for customers that are driving their strategy around developers who are tasked with building analytics into their applications. The Forrester Wave™: Translytical Data Platforms, Q4 2022 Evaluating the top vendors in the Translytic Data Platforms Wave Forrester evaluated 15 of the most significant translytical data platform vendors against 26 criteria. These criteria span current offering and strategy through to market presence. Forrester gave MongoDB the highest possible scores across eleven criteria, including: Number of customers Performance Scalability Dev Tools/API Multi-model Streaming Cloud / On-prem / distributed architecture Commercial model The report cites that “MongoDB ramps up its translytical offering aggressively”, and that “Organizations use MongoDB to support real-time analytics, systems of insight, customer 360, internet of things (IoT), and mobile applications.” Access your complimentary copy of the report here . Customer Momentum Many development teams start out using MongoDB as an operational database for both new cloud-native services as well as modernized legacy apps. More and more of these teams are now improving customer experience and speeding business insight by adopting application-driven analytics. Examples include: Bosch for predictive maintenance using IoT sensor data. Keller Williams for relevance-based property search and sales dashboarding. Iron Mountain for AI-based information discovery and intelligence. Volvo Connect for fleet management. Getting started on your Translytics Journey The MongoDB Atlas developer data platform is engineered to help you make the shift to Translytics and application-driven analytics – leading to smarter apps and increased business visibility. The best way to get started is to sign up for an account on MongoDB Atlas . Then create a free database cluster, load your own data or our sample data sets, and explore what’s possible within the platform. The MongoDB Developer Center hosts an array of resources including tutorials, sample code, videos, and documentation organized by programming language and product. Whether you are a developer or a member of an analytics team, it's never been easier to get started enriching your transactional workloads with analytics!

MongoDB and AWS: How a decade-old collaboration got even better in 2022

Developers select MongoDB because it makes building with data for almost any class of application easy and fast for them. They select Amazon Web Services (AWS) because it offers a comprehensive and broadly adopted cloud platform, offering more than 200 fully featured services. Bringing together MongoDB Atlas on AWS helps developers build and ship higher quality applications faster and scale them further. MongoDB has collaborated with AWS for close to a decade now, but 2022 has seen dramatic growth in both the quantity and quality of our joint activities, resulting in a strategic collaboration agreement announced earlier this year. Our collaboration spans joint product engineering and integration so MongoDB Atlas is a first-party service on AWS, and also extends to making it easy for customers to procure MongoDB Atlas on AWS. In 2022, we have worked more closely together than ever before. In this post, we'll cover what we've achieved, and how our customers benefit. If at any point you want to stop reading about the partnership and experience it in action, we invite you to get started for free with MongoDB's fully managed, pay-as-you-go listing on the AWS Marketplace . Delivering an outstanding customer experience Since re:Invent 2021, MongoDB and AWS have jointly seen an explosion in customer success, with MongoDB for Startups becoming one of the most widely used offerings in the AWS Activate program after we launched in July. And, since launching in the AWS Marketplace with pay-as-you-go pricing in December 2021, MongoDB Atlas has become one of the most popular self-service listings, with well over 1,000 customers. More broadly, we've seen our AWS Marketplace business show triple-digit growth through significant, mutual investments across engineering, sales, and marketing. We've also found great success working with AWS' Workload Migration and Proof of Concept programs, helping many new customers accelerate their migration to MongoDB Atlas on AWS over the past 12 months. Additionally, while MongoDB works closely with AWS across the globe, we devoted increased attention to Europe this past year, resulting in a considerable increase in customer adoption. As a result, AWS named us their AWS Marketplace Partner of the Year - EMEA in November 2022. One way that we've helped to accelerate such customer success is by making it easier to procure MongoDB Atlas on AWS. Over the past year, MongoDB and AWS have significantly simplified the purchasing experience for customers. We did this across a few key areas. One thing customers love about buying through AWS Marketplace is how seamless it makes the purchasing experience. However, historically this has been slowed somewhat for MongoDB customers by the need to agree to separate legal terms. Starting in November 2022, however, all Atlas on AWS customers purchasing through the AWS Marketplace Self Service listing use AWS Marketplace’s Standard Contract for Marketplace (SCMP) terms and conditions rather than MongoDB Cloud Terms of Service, thereby further reducing friction to getting productive, faster, with MongoDB. Close product collaboration Behind these improvements to our joint purchasing experience were significant improvements to how MongoDB Atlas integrates with key AWS services. MongoDB has long worked seamlessly with core AWS services such as Amazon Elastic Compute Cloud (Amazon EC2) and Amazon Simple Storage Service (Amazon S3), and more recently has collaborated with AWS to ensure tight integration with AWS container services like Amazon Elastic Kubernetes Service (Amazon EKS) and Amazon Elastic Container Service (Amazon ECS), AWS serverless technologies like AWS Lambda, Amazon Eventbridge, and AWS Fargate; and edge computing services like AWS Wavelength . Over the past year, however, we've delved more deeply into AWS machine learning services (Amazon Comprehend, Amazon Kendra, Amazon Lex, etc.), AWS AppSync, Amazon Forecast, AWS Elastic Beanstalk, and more. In addition to direct integrations with AWS services, we made it simpler for customers to use MongoDB with important joint partners such as Datadog, Databricks, and Confluent. For Datadog, we improved MongoDB Atlas App Service to support forwarding logs on AWS to Datadog, thereby improving observability through real-time log analytics. With Databricks, we announced MongoDB as a data source within a Databricks notebook, thereby offering data practitioners an easier, more curated experience for connecting Databricks to MongoDB Atlas data. And with Confluent, we strengthened our integrations to help developers easily build robust, reactive data pipelines that stream events between applications and services in real time. Through innovations to the purchasing process and the product experience, we've helped make thousands of customers successful running MongoDB on AWS. Some joint customers, like Unqork , are upending entire industries with innovative approaches to technology and business. Others, like Volvo's Connected Solutions business , rely on MongoDB and AWS to scale their fleet management solution from tens of millions to billions of daily events. Other recent customers include Verizon , Marsello , GLS , and Shopline . Get started with MongoDB Atlas on AWS You needn't take our word for it, however. With just a few clicks — and no risk — you can get started for free with MongoDB Atlas on AWS . There's no upfront commitment, and if you choose to continue to build with MongoDB on AWS, you only pay for what you use.

3 Key Characteristics of Modernization

Analyst and research firm TDWI released its latest report on IT modernization: Maximizing the Business Value of Data: Platforms, Integration, and Management . The report reveals the modernization strategies, objectives, and experiences of more than 300 IT executives, data analysts, data scientists, developers, and enterprise architects. Within the survey itself lies the deeper, fundamental question of what is IT modernization in today's digital economy? It's an important question because it gets at the heart of why organizations want and need to modernize in the first place. Considering the effort, expense, and risks of modernizing, there needs to be a compelling purpose guiding the process in order to keep it on track and ensure its success. By dissecting the TDWI survey questions and responses, we can deduce what the three key characteristics of modernization are. #1: Modernization capabilities If we were to examine the elements and components that comprise modernized architecture, we would get a sense of what modernization looks like but not the purpose behind its deployment. So instead, let's start by looking at the capabilities modern architecture enables so we can get a clearer view of its characteristics and why they matter. Seventy-three percent of survey respondents reported that data democratization and self-service functionality are either extremely or very important. We've heard from numerous organizations that the task of managing data access at companies is slowing down innovation. Ben Herzberg, chief data scientist for data access company, Satori, recently told us , "The majority of organizations are still managing access to data in a manual way. Everyone is feeling the bottleneck. The data analyst who wants to do their job in a meaningful way just wants to understand what data sets they can use and get access to it fast." Getting access to data can be challenging without some sort of self-service data access capability. "Sometimes you have to go through three or four different teams to get access to data," Herzberg says. "It can take a week or two." The TDWI report also indicated a long-standing trend toward easier, more intuitive experiences extending to data integration, data pipelines, data catalog interaction, and monitoring. Survey respondents' top priorities over the next 12 months support this trend. In addition to migrating and consolidating data in the cloud, they intend to prioritize the following key capabilities: Enabling better data management for data science, AI, and ML Supporting development and deployment of data driven applications Supporting expansion in self service Business intelligence (BI) and analytics users Unifying management of data across distributed systems BI and analytics platforms remain one of the fastest growing software markets. The capabilities necessary to power these systems are in high demand: self-service analytics, faster discovery, predictions based on real-time operational data, and integration of rich and streaming data sets. The survey responses also showed that handling an increase in data volume and the number of concurrent users are modernization priorities. And there's pressure to reduce data latency and increase the frequency of updates. The survey showed that one of the most challenging capabilities organizations are dealing with is enabling low latency querying, search, and analytics. Giving users the right data at the right time to answer business questions, solve problems, and innovate with data is critical today and it depends on these capabilities. #2: Modernization outcomes The capabilities organizations seek only serve their modernization goals as far as they enable specific outcomes. And it's outcomes that are ultimately driving modernization initiatives. According to the survey, the number one outcome organizations seek to bring about is gaining fuller value from the data they store and capture. Forty-six percent of respondents cited it as their top challenge. Automating decision-making is another outcome organizations are seeking. Thirty-two percent of respondents rated automating decisions in operations in processes as very important. But it relies on the timely flow of insights into apps, one of the key capabilities identified earlier. Other key modernization outcomes cited in the survey include: Increase efficiency and effectiveness Generate new business strategies and models using analytics Make faster decisions Strengthen relationships via data sharing Improve trust and data quality Increase reuse and flexibility Reduce costs Provide authorized access to live data sets Consolidate data silos Developers in the survey said they were seeking to embed richer, personalized application experiences, with 52% saying they wanted seamless access to diverse data sets and sources. But first, they'll have to overcome several challenges that so far have proved difficult to solve. Sixty-eight percent of respondents said they face challenges processing streaming data and change data capture updates, and 64% struggle to integrate streaming with fast, high volume queries, and the same percentage said they struggle with combining historical and real-time analytics. #3: Modernization platform Modernized problems require modernized solutions. And the one most most commonly cited by respondents was a data platform , which they believe is the key to maximizing value from data. A data platform solves the issue of consolidating unnecessary data silos and ensuring access to data without the hassle of manual intervention or the risk of unauthorized access. Flexibility in the data platform is critical since data environments will continue to evolve, even after modernization milestones have been met. A data platform is one of the key elements that comprise modernized architecture. The TDWI survey cited several other advantages of unifying distributed data within a data platform: Simplifying and accelerating access Discovering data relationships easier and faster Creating a logical layer for single point of access Unifying data governance Reducing unnecessary data movement Modernized architecture Fifty-four percent of respondents said they were in the process of modernizing, and 29% were planning on doing so. The most frequently cited architectural feature by those modernizing or planning to was cloud migration from on-premises systems, with the goal being to change the dimensions of what was possible. But it wasn't just shifting to the cloud that respondents mentioned. The survey also indicated the prevalence of hybrid multi-cloud architectures as well, with data integration and management that span distributed data environments. Distributed architectures can lead to higher performance by putting data closest to where it's being used. It also solves data sovereignty issues by putting data where it's required to be due to regulatory jurisdiction. The report also mentions serverless architecture due to its pay-as-you-go computing model and improved business alignment. With serverless architecture , developers can build applications without thinking about infrastructure or traditional server management.

10 years of MongoDB customers at AWS re:Invent

MongoDB has attended AWS re:Invent since its inception in 2012. A key reason for this is, of course, to help strengthen our partnership with AWS, which really began in 2015 and significantly expanded in March 2022 with a global, strategic collaboration agreement. But an even more fundamental reason for MongoDB's continued presence at AWS re:Invent over the years is the opportunity to engage with our many joint customers. Several MongoDB customers have been featured in re:Invent keynotes over the years. In fact, looking back at the customers AWS chose to feature in its keynotes, it's hard to find examples that are not MongoDB customers. Earlier this year, AWS celebrated 10 years of re:Invent by showcasing an equal number of "memorable customer moments" from the re:Invent mainstage. It was a great way to reaffirm AWS Leadership Principle #1 (Customer Obsession). It was also a great way to shine a light on the great things MongoDB's customers are doing. Rather than rewind on the many MongoDB customers spotlighted at re:Invent, let's look at those AWS called "most memorable" in its blog. All in on cloud Back in 2015, Capital One CIO Rob Alexander took to the re:Invent stage to discuss Capital One's "all in" approach to cloud. "We’re either using or experimenting with nearly every AWS service," Alexander said. What he didn't say, but which the company has been quite public about over the years, was how Capital One uses MongoDB in tandem with AWS services. A few months after Alexander's re:Invent comments, Capital One's Oron Gill Haus spoke at MongoDB World on Hygieia , the company's open source DevOps dashboard. Hygieia, built on MongoDB, provides the foundation for the company's attempts to reimagine banking. Haus detailed why MongoDB is so critical to Capital One's need to innovate quickly on customers' behalf, stressing how the variety and velocity of data makes MongoDB an ideal solution: We get data in from all different kinds of sources and formats, and we get it at different times. Now, what we have to do is predict the future and how you're planning on using the data. That's where traditional databases fall down. That's where you'll see MongoDB. We want to have the ability to find insights and be able to react quickly to those insights. Years later, Capital One advertises hundreds of jobs for those with MongoDB experience. (Hint: You may need to know how to roll back a MongoDB query for some of those jobs.) Capital One is doing impressive work with MongoDB, but it's not alone in its use of MongoDB for financial services. Goldman Sachs, Citi, Barclays, BBVA, Charles Schwab, FICO, HSBC, and Intuit are just a few MongoDB customers that have spoken publicly of how and why they use MongoDB. And, yes, some of these companies you may remember from the re:Invent main stage over the years. MongoDB to the Moon! Years before NASA Jet Propulsion Laboratory (JPL) took to the re:Invent stage (2016), the U.S. public agency was running MongoDB throughout NASA . By 2018, MongoDB was involved in the hugely interesting NASA Deep Space Network (DSN), a primary resource for communications and navigation for NASA's and partner agencies' interplanetary space missions. NASA had recently upgraded its decades-old infrastructure to base its modern Loading Analysis and Planning Software (LAPS) on Linux and MongoDB. LAPS, as a scientific paper details , "is responsible for long-term planning and forecasting, including studies and analysis of new missions, changed mission requirements, downtime, and new or changed antenna capabilities." Around the same time, and a key part of DSN operations, NASA was also looking for ways to improve the efficiency of operating antennas across the globe. The heart of this initiative was NASA's Link Complexity and Maintenance software (LCM), which stores all pertinent data in MongoDB. Hence, while it might not be accurate to say that MongoDB runs on the Moon, it would be true to say MongoDB helps NASA manage space missions to the Moon—and beyond. Can you hear me now? "[I]t’s just a massive moment for us at Verizon,” declared Hans Vestberg, chairman and CEO of Verizon, at re:Invent in 2019. He was talking about the company's partnership with AWS to deliver 5G network edge computing using AWS Wavelength. What wasn't said in the keynote, but that Robert Belson, Principal Engineer, Corporate Strategy, Verizon, explained , is that the vision was incomplete without MongoDB. “Verizon 5G Edge is a mobile edge computing platform, which embeds popular hyperscaler compute and storage, such as AWS Wavelength, at the edge of our 4G and 5G networks so application builders can extend existing workloads using the same popular services they know and love," he explained. “However, certain services, such as databases, are not natively supported, which is where [MongoDB] Atlas and Realm come into play by creating unprecedented flexibility for the developer and the end customer.” As we've described, Verizon decided that a comprehensive data platform was needed to make its 5G edge computing dream a reality. So Verizon integrated Atlas Functions with the Verizon edge discovery service to help direct 5G mobile clients to the topologically closest database instance across a customer’s edge deployment. In tandem, Verizon has overlaid a data persistence layer using MongoDB Realm, thereby enabling personalized experiences to extend to the network edge. Verizon is also using Atlas Device Sync and Realm to ensure the seamless synchronization of data between devices, the cloud and edge-of-network, online and offline. Customers love MongoDB + AWS Beginning to see a pattern here? While not every customer highlighted by AWS at re:Invent is a MongoDB customer, many are, including the few for which we've been able to provide some detail. Others include Epic Games, which runs its wildly popular game Fortnite on MongoDB ; or Volkswagen, which uses MongoDB throughout its web applications and in its Car Net service ; or Siemens, which runs MongoDB at the heart of its Monet system to provide monitoring, controlling, and remote management of field devices for advanced energy management services. This year while watching the various customers take the stage in re:Invent keynotes, keep in mind that they're also very likely a MongoDB customer, because customers that seek the agility and performance of AWS also tend to like how MongoDB's flexible data model enables them to do much more with their data. Interested in learning more? The best way might be to try fully managed MongoDB Atlas for free. You can get started now .

Modernize your GraphQL APIs with MongoDB Atlas and AWS AppSync

Modern applications typically need data from a variety of data sources, which are frequently backed by different databases and fronted by a multitude of REST APIs. Consolidating the data into a single coherent API presents a significant challenge for application developers. GraphQL emerged as a leading data query and manipulation language to simplify consolidating various APIs. GraphQL provides a complete and understandable description of the data in your API, giving clients the power to ask for exactly what they need — while making it easier to evolve APIs over time. It complements popular development stacks like MEAN and MERN , aggregating data from multiple origins into a single source that applications can then easily interact with. MongoDB Atlas: A modern developer data platform MongoDB Atlas is a modern developer data platform with a fully managed cloud database at its core. It provides rich features like native time series collections, geospatial data, multi-level indexing, search, isolated workloads, and many more — all built on top of the flexible MongoDB document data model. MongoDB Atlas App Services help developers build apps, integrate services, and connect to their data by reducing operational overhead through features such as hosted Data API and GraphQL API. The Atlas Data API allows developers to easily integrate Atlas data into their cloud apps and services over HTTPS with a flexible, REST-like API layer. The Atlas GraphQL API lets developers access Atlas data from any standard GraphQL client with an API that generates based on your data’s schema. AWS AppSync: Serverless GrapghQL and pub/sub APIs AWS AppSync is an AWS managed service that allows developers to build GraphQL and Pub/Sub APIs. With AWS AppSync, developers can create APIs that access data from one or many sources and enable real-time interactions in their applications. The resulting APIs are serverless, automatically scale to meet the throughput and latency requirements of the most demanding applications, and charge only for requests to the API and by real-time messages delivered. Exposing your MongoDB Data over a scalable GraphQL API with AWS AppSync Together, AWS AppSync and MongoDB Atlas help developers create GraphQL APIs by integrating multiple REST APIs and data sources on AWS. This gives frontend developers a single GraphQL API data source to drive their applications. Compared to REST APIs, developers get flexibility in defining the structure of the data while reducing the payload size by bringing only the attributes that are required. Additionally, developers are able to take advantage of other AWS services such as Amazon Cognito, AWS Amplify, Amazon API Gateway, and AWS Lambda when building modern applications. This allows for a severless end-to-end architecture, which is backed by MongoDB Atlas serverless instances and available in pay-as-you-go mode from the AWS Marketplace . Paths to integration AWS AppSync uses data sources and resolvers to translate GraphQL requests and to retrieve data; for example, users can fetch MongoDB Atlas data using AppSync Direct Lambda Resolvers. Below, we explore two approaches to implementing Lambda Resolvers: using the Atlas Data API or connecting directly via MongoDB drivers . Using the Atlas Data API in a Direct Lambda Resolver With this approach, developers leverage the pre-created Atlas Data API when building a Direct Lambda Resolver. This ready-made API acts as a data source in the resolver, and supports popular authentication mechanisms based on API Keys, JWT, or email-password. This enables seamless integration with Amazon Cognito to manage customer identity and access. The Atlas Data API lets you read and write data in Atlas using standard HTTPS requests and comes with managed networking and connections, replacing your typical app server. Any runtime capable of making HTTPS calls is compatible with the API. Figure 1:   Architecture details of Direct Lambda Resolver with Data API Figure 1 shows how AWS AppSync leverages the AWS Lambda Direct Resolver to connect to the MongoDB Atlas Data API. The Atlas Data API then interacts with your Atlas Cluster to retrieve and store the data. MongoDB driver-based Direct Lambda Resolver With this option, the Lambda Resolver connects to MongoDB Atlas directly via drivers , which are available in multiple programming languages and provide idiomatic access to MongoDB. MongoDB drivers support a rich set of functionality and options , including the MongoDB Query Language, write and read concerns, and more. Figure 2:   Details the architecture of Direct Lambda Resolvers through native MongoDB drivers Figure 2 shows how the AWS AppSync endpoint leverages Lambda Resolvers to connect to MongoDB Atlas. The Lambda function uses a MongoDB driver to make a direct connection to the Atlas cluster, and to retrieve and store data. The table below summarizes the different resolver implementation approaches. Table 1:   Feature comparison of resolver implementations Setup Atlas Cluster Set up a free cluster in MongoDB Atlas. Configure the database for network security and access. Set up the Data API. Secrect Manager Create the AWS Secret Manager to securely store database credentials. Lambda Function Create Lambda functions with the MongoDB Data APIs or MongoDB drivers as shown in this Github tutorial . AWS AppSync setup Set up AWS Appsync to configure the data source and query. Test API Test the AWS AppSync APIs using the AWS Console or Postman . Figure 3:   Test results for the AWS AppSync query Conclusion To learn more, refer to the AppSync Atlas Integration GitHub repository for step-by-step instructions and sample code. This solution can be extended to AWS Amplify for building mobile applications. For further information, please contact partners@mongodb.com .

MongoDB and AWS: Simplifying OSDU Metadata Management

In this decade of the 2020s, the energy sector is experiencing two major changes at the same time: The transition from fossil to renewables, and the digital transformation that changes the way businesses operate through better applications and tools that help streamline and automate processes. To support both of these challenges, the Open Group OSDU Forum has created a new data platform standard for the energy industry that seeks to reduce data silos and enable transformational workflows via an open, standards-based API set and supporting ecosystem. OSDU (Open Subsurface Data Universe) is an industry-defining initiative that provides a unified approach to store and retrieve data in a standardized way in order to allow reductions in infrastructure cost, simplify the integration of separate business areas, and adopt new energy verticals within the same architectural principles. Amazon Web Services (AWS) — as an early supporter of OSDU — provides a premier, cloud-first offering available across more than 87 availability zones and 27 regions. MongoDB — an OSDU member since 2019 — and AWS are collaborating to leverage MongoDB as part of the AWS OSDU platform for added flexibility and to provide a robust multi-region OSDU offering to major customers. Why MongoDB for OSDU? OSDU provides a unique challenge, as its architecture is set to support a varied data set originating from the oil and gas industry, while also being extensible enough to support the expanding requirements of new energy and renewables. It must be able to support single-use on a laptop for beginning practitioners, yet scale to the needs of experts with varying deployment scenarios — from on-premises, in-field, and cloud — and from single tenant on one region to multi-region and multi-tenant applications. Furthermore, OSDU architectural principles separate raw object data from the metadata that describes it, which puts an additional burden on the flexibility needed to manage OSDU metadata, while supporting all the above requirements. Enter MongoDB Since 2008, MongoDB has championed the use of the document model as the data store that supports a flexible JSON-type structure, which can be considered a superset of different existing data types — from tabular, key-value, and text to geo-spatial, graph, and time series. Thus, MongoDB has the flexibility not only to support just the main metadata services in OSDU but also to adapt to the needs of domain-specific services as OSDU evolves. The flexibility of MongoDB allows users to model and query the data in a variety of ways within the same architecture without the need to proliferate disparate databases for each specific data type, which incurs overhead both in terms of deployment, cost and scale, and the ability to query. The schema flexibility inherent in this document model allows developers to adapt and make changes quickly, without the operational burden that comes with schema changes with traditional tabular databases. MongoDB can also scale from the smallest environment to massive, multi-region deployments, with cross-regional data replication support that is available today across more than 90 regions with MongoDB Atlas . With the addition of MongoDB’s cluster-to-cluster sync , MongoDB can easily support hybrid deployments bridging on-premises or edge to the cloud, a requirement that is increasingly important for energy supermajors or for regions where data sovereignty is paramount. Example: LegalTag An example of the benefit of MongoDB’s document model is OSDU’s LegalTag Compliance Service , which governs the legal status of data in the OSDU data ecosystem. It is a collection of JSON properties that governs how the data can be consumed and ingested. With MongoDB, the properties are directly stored, indexed, and made available to be queried — even via full-text search for more advanced use cases. The schema flexibility simplifies integrating additional derived data from ingested data sources, which is utilized for the further enrichment of the LegalTag metadata. Here the JSON document can accommodate more nodes to integrate this data without the need for new tables and data structures that need to be created and managed. AWS OSDU with MongoDB MongoDB and AWS collaborated to provide a MongoDB-based metadata implementation (Figure 1), which is available for all main OSDU services: Partition, Entitlements, Legal, Schema, Storage. The AWS default ODSU Partition service leverages MongoDB due to its simple replication capabilities (auto-deployable via CloudFormation, Terraform, and Kubernetes), which simplify identifying the correct connection information at runtime to the correct OSDU partition in a multi-region and multi-cluster deployment. The OSDU Entitlements service manages authorization and permissions for access to OSDU services and its data-using groups. The most recent OSDU reference implementation for Entitlements leverages a graph model to manage the relationship between groups, members, and owners. Thus, AWS again chose MongoDB with its inherent graph capabilities through the document model to simplify the implementation without the need to integrate a further dedicated database technology into the architecture. Figure 1:   MongoDB metadata service options with AWS OSDU. Other potential benefits for OSDU MongoDB also offers workload isolation , which provides the ability to dedicate instances only for reporting workloads against the operational dataset. This provides the ability to create real-time observability of the system based on the activity on metadata. Triggers and aggregation pipelines allow the creation of an alternate view of activity in real-time, which can easily be visualized via MongoDB Charts (part of Atlas) without the need for a dedicated visualization system. Flexibility and consistency A major use case for both the energy industry and the direction of OSDU is the ability to capture and preprocess data closest to where it originated. For remote locations where direct connections to the cloud are prohibitive, this approach is often the only option — think Arctic or off-shore locations. Additionally, certain countries have data sovereignty laws that require an alternative deployment option outside of the public cloud. A MongoDB-based OSDU implementation can provide a distinct advantage, as MongoDB as a data platform itself supports deployment in the field (e.g., off-shore), on-premises, in private cloud (e.g., Kubernetes, Terraform), public cloud (e.g., AWS) and as a SaaS implementation (e.g., Atlas). Adoption of MongoDB for OSDU provides consistency across different deployment/cloud scenarios, thereby reducing the overhead for managing and operating a disparate set of technologies where multiple scenarios are required. Conclusion OSDU has been created to change the way data is collected and shared across the oil and gas and energy industry. Its intent is to accelerate digital transformation within the industry. The range of use cases and deployment scenarios requires a solution that provides flexibility in the supported datasets, flexibility for the developer to innovate without additional schema and operational burden, as well as flexibility to be deployable in various environments.

Manage and Store Data Where You Want with MongoDB

Increasingly, data is stored in a public cloud as companies realize the agility and cost benefits of running on cloud infrastructure. At any given time, however, organizations must know where their data is located, replicated, and stored — as well as how it is collected and processed to constantly ensure personal data privacy. Creating a proper structure for storing your data just where you want it can be complex, especially with the shift towards geographically dispersed data and the need to comply with local and regional privacy and data security requirements. Organizations without a strong handle on where their data is stored potentially risk millions of dollars in regulatory fines for mishandling data, loss of brand credibility, and distrust from customers. Geographically dispersed data and various compliance regulations also impact how organizations design their applications, and many see these challenges as an opportunity to transform how they engage with data. For example, organizations get the benefits of a multi-cloud strategy and avoid vendor lock-in, knowing that they can still run on-premises or on a different cloud provider. However, a flexible data model is needed to keep data within the confines of the country or region where the data originates. MongoDB runs where you want your data to be — on-premises, in the cloud, or as an on-demand, fully managed global cloud database. In this article, we’ll look at ways MongoDB can help you keep your data exactly where you need it. Major considerations for managing data When managing data, organizations must answer questions in several key areas, including: Process: How is your company going to scale security practices and automate compliance for the most prevalent data security and privacy regulatory frameworks? Penalties: Are your business leaders fully aware of the costs associated with not adhering to regulations when storing and managing your data? Scalability: Do you have an application that you anticipate will grow in the future and can scale automatically as demand requires? Infrastructure: Is legacy infrastructure keeping you from being able to easily comply with data regulations? Flexibility: Is your data architecture agile enough to meet regulations quickly as they grow in breadth and complexity? Cost: Are you wasting time and money with manual processes when adhering to regulations and risking hefty fines related to noncompliance? How companies use MongoDB to store data where they want and need it When storing and managing data in different regions and countries, organizations must also understand the rules and regulations that apply. MongoDB is uniquely positioned to support organizations to meet their data goals with intuitive security features and privacy controls, as well as the ability to geographically deploy data clusters and backups in one or several regions. Zones in sharded clusters MongoDB uses sharding to support deployments with very large data sets and high-throughput operations. In sharded clusters, you can create zones of sharded data based on the shard key, which helps improve the locality of data. Network isolation and access Each MongoDB Atlas project is provisioned into its own virtual private cloud (VPC), thereby isolating your data and underlying systems from other MongoDB Atlas users. This approach allows businesses to meet data requirements while staying highly available within each region. Each shard of data will have multiple nodes that automatically and transparently fail over for zero downtime, all within the same region. Multi-cloud clusters MongoDB Atlas is the only globally distributed, multi-cloud database. It lets you deploy a single cluster across AWS, Microsoft Azure, and Google Cloud without the operational complexity of managing data replication and migration across clouds. With the ability to define a geographic location for each document, your teams can also keep relevant data close to end users for regulatory compliance. IP whitelists IP whitelists allow you to specify a specific range of IP addresses against which access will be granted, delivering granular control over data. Queryable encryption Queryable encryption enables encryption of sensitive data from the client side, stored as fully randomized, encrypted data on the database server side. This feature delivers the utmost in security without sacrificing performance and is available on both MongoDB Atlas and Enterprise Advanced. MongoDB Atlas global clusters Atlas global clusters allow organizations with distributed applications to geographically partition a fully managed deployment in a few clicks and control the distribution and placement of their data with sophisticated policies that can be easily generated and changed. Thus, your organization can not only achieve compliance with local data protection regulations more easily but also reduce overhead. Client-Side Field Level Encryption MongoDB’s Client-Side Field Level Encryption (FLE) dramatically reduces the risk of unauthorized access or disclosure of sensitive data. Fields are encrypted before they leave your application, protecting them everywhere — in motion over the network, in database memory, at rest in storage and backups, and in system logs. Segmenting data by location with sharded clusters As your application gets more popular, you may reach a point where your servers will reach their maximum load. Before you reach that point, you must plan for scaling your database to adjust resources to meet demand. Scaling can occur temporarily, with a sudden burst of traffic, or permanently with a constant increase in the popularity of your services. Increased usage of your application brings three main challenges to your database server: The CPU and/or memory becomes overloaded, and the database server either cannot respond to all the request throughput, or do so in a reasonable amount of time. Your database server runs out of storage and thus cannot store all the data. Your network interface is overloaded, so it cannot support all the network traffic received. When your system resource limits are reached, you will want to consider scaling your database. Horizontal scaling refers to bringing on additional nodes to share the load. This process is difficult with relational databases because of the difficulty in spreading out related data across nodes. With non-relational databases, this is made simpler because collections are self-contained and not coupled relationally. This approach allows them to be distributed across nodes more simply, as queries do not have to “join” them together across nodes. Horizontal scaling with MongoDB Atlas is achieved through sharding. With sharded clusters, you can create zones of sharded data based on the shard key . You can associate each zone with one or more shards in the cluster. A shard can be associated with any number of zones. In a balanced cluster, MongoDB migrates chunks covered by a zone only to those shards associated with the zone: If one of the data centers goes down, the data is still available for reads unlike a single data center distribution. If the data center with a minority of the members goes down, the replica set can still serve write operations as well as read operations. However, if the data center with the majority of the members goes down, the replica set becomes read-only. Figure 1 illustrates a sharded cluster that uses geographic zones to manage and satisfy data segmentation requirements. Figure 1:   Sharded cluster Other benefits of MongoDB Atlas MongoDB Atlas also provides organizations with an intuitive UI or administration API to efficiently perform tasks that would otherwise be very difficult. Upgrading your servers or setting up sharding without having to shut down your servers can be a challenge, but MongoDB Atlas removes this layer of difficulty through the features described here. With MongoDB, scaling your databases can be done with a couple of clicks. Meeting your data goals with MongoDB Organizations are uniquely positioned to store and manage data where they want it with MongoDB’s range of features discussed above. With the shift towards geographically dispersed data, organizations must make sure they are aware of – and fully understand – the local and regional rules and requirements that apply for storing and managing data.

Optimizing Your MongoDB Deployment with Performance Advisor

We are happy to announce additional enhancements to MongoDB’s Performance Advisor, now available in MongoDB Atlas , MongoDB Cloud Manager , and MongoDB Ops Manager . MongoDB’s Performance Advisor automatically analyzes logs for slow-running queries and provides index suggestions to improve query performance. In this latest update, we’ve made some key updates, including: A new ranking algorithm and additional performance statistics (e.g., average documents scanned, average documents returned, and average object size) make it easier to understand the relative importance of each index recommendation. Support for additional query types including regexes, negation operators (e.g., $ne, $nin, $not), $count, $distinct, and $match to ensure we cover with optimized index suggestions. Index recommendations are now more deterministic so they are less impacted by time and provide more consistent query performance benefits. Before diving further into MongoDB’s Performance Advisor, let’s look at tools MongoDB provides out of the box to simplify database monitoring. Background Deploying your MongoDB cluster and getting your database running is a critical first step, but another important aspect of managing your database is ensuring that your database is performant and running efficiently. To make this easier for you, MongoDB offers several out-of-the-box monitoring tools , such as the Query Profiler, Performance Advisor, Real-Time Performance Panel, and Metrics Charts, to name a few. Suppose you notice that your database queries are running slower. The first place you might go is to the metrics charts to look at the “Opcounters” metrics to see whether you have more operations running. You might also look at the “Operation Execution Time” to see if your queries are taking longer to run. The “Query Targeting” metric shows the ratio of the number of documents scanned over the number of documents returned. This datapoint is a great measure of the overall efficiency of a query — the higher the ratio, the less efficient the query. These and other metrics can help you identify performance issues with your overall cluster, which you can then use as context to dive a level deeper and perform more targeted diagnostics of individual slow-running queries . MongoDB’s Performance Advisor takes this functionality a step further by automatically scanning your slowest queries and recommending indexes where appropriate to improve query performance. Getting started with Performance Advisor The Performance Advisor is a unique tool that automatically monitors MongoDB logs for slow-running queries and suggests indexes to improve query performance. Performance Advisor also helps improve both your read and write performance by intelligently recommending indexes to create and/or drop (Figure 1). These suggestions are ranked by the determined impact on your cluster. Performance Advisor is available on M10 and above clusters in MongoDB Atlas as well as in Cloud Manager and Ops Manager. Figure 1:  Performance Advisor can recommend indexes to create or drop. Performance Advisor will suggest which indexes to create, what queries will be affected by the index, and the expected improvements to query performance. All of these user interactions are available in the user interface directly within Performance Advisor, and indexes can be easily created with just a few clicks. Figure 2 shows additional Performance Advisor statistics about the performance improvements this index would provide. The performance statistics that are highlighted for each index recommendation include: Execution Count: The number of queries per hour that would be covered by the recommended index Avg Execution Time: The average execution time of queries that would be covered by the recommended index Avg Query Targeting: The inefficiency of queries that would be covered by the recommended index, measured by the number of documents or index keys scanned in order to return one document In Memory Sort: The number of in-memory sorts performed per hour for queries that would be covered by the recommended index Avg Docs Scanned: The average number of documents that were scanned by slow queries with this query shape Avg Docs Returned: The average number of documents that were returned by slow queries with this query shape Avg Object Size: The average object size of all objects in the impacted collection If you have multiple index recommendations, they are ranked by their relative impact to query performance so that the most beneficial index suggestion is displayed at the top. This means that the most impactful index is displayed at the top and would be the most beneficial to query performance. Figure 2:  Detailed performance statistics. Creating optimal indexes ensures that queries are not scanning more documents than they return. However, creating too many indexes can slow down write performance, as each write operation needs to check each index before writing. Performance Advisor provides suggestions on which indexes to drop based on whether they are unused or redundant (Figure 3). Users also have the option to “hide” indexes as a way to evaluate the impact of dropping an index without actually dropping the index. Figure 3: Performance Advisor shows which indexes are unused or redundant. The Performance Advisor in MongoDB provides a simple and cost-efficient way to ensure you’re getting the best performance out of your MongoDB database. If you’d like to see the Performance Advisor in action, the easiest way to get started is to sign up for MongoDB Atlas , our cloud database service. Performance Advisor is available on MongoDB Atlas on M10 cluster tiers and higher. Learn more from the following resources: Monitor and Improve Slow Queries Monitor Your Database Deployments

Start on Your Journey to Operationalize AI-Enhanced Real-Time Applications with MongoDB and Databricks

MongoDB and Databricks have succeeded in two complementary worlds: For MongoDB , the focus is making the world of data easy for developers building applications. For Databricks, the focus is helping enterprises to unify their data, analytics, and AI by combining a data lake's flexibility with the openness, performance, and governance of a data warehouse. Traditionally, these operational and analytical functions have existed in separate domains built by different teams and serving different audiences. Though some will pretend a data warehouse can unify such disparate data and systems, the reality is this approach leaves you making false trade-offs where your developers, your data scientists, and, ultimately, your applications and customers suffer. Data warehouses are not designed to serve consumer-facing applications at scale and process machine learning in real time. It takes the unique application-serving layer of a MongoDB database, combined with the scale and real-time capabilities of a lakehouse, such as Databricks, to automate and operationalize complex and AI-enhanced applications at scale. We observed that a large and growing population of joint customers has for years enabled the flow of data between our two platforms to run real-time businesses and enable a world of application-driven analytics, using MongoDB Connector for Apache Spark . So we asked ourselves: How could we make that a more seamless and elegant experience for these customers? Today we're announcing that Databricks now features MongoDB as a data source within a Databricks notebook , thereby enabling data practitioners with an easier, more curated experience for connecting Databricks with MongoDB Atlas data. This notebook experience makes it simpler for enterprises to deliver real-time analytics, handle complex data warehouse/BI workloads, and to operationalize AI/ML pipelines using the MongoDB Spark Connector . In turn, developer and data teams can collaborate more closely on building a new generation of app-driven intelligence. MongoDB and Databricks are committed to further improve our integration in the coming months. In this post, we'll explain how Databricks can be used as a real-time processing layer for data on MongoDB Atlas using the Spark Connector, extending MongoDB's built-in data processing capabilities like our aggregation framework . We'll also cover how to use Databricks' MongoDB notebook to make this even easier. In future posts we'll outline how to use MongoDB Atlas and Databricks Delta Lake to build sophisticated AI/ML pipelines. Live application data plus the data lakehouse MongoDB Atlas is a fully-managed developer data platform that powers a wide variety of workloads - supporting everything from simple CRUD operations to sophisticated data processing pipelines for analytics and transformation - all with a common query interface. With MongoDB Atlas you can isolate operational and analytical workloads using dedicated analytical nodes. Analytics nodes are read-only nodes that can be exclusively targeted by your queries Let's look at an example. Assume you have long-running analytical queries that you want to run against your cluster and your operations team does not want these queries competing for resources with your regular operational workload. To address this, you add an analytics node to your cluster and then target it in your connection string using an Atlas replica set tag. You can connect to the analytical nodes to run sophisticated aggregation queries, BI and reporting workloads using the Atlas SQL interface , visualize your data using MongoDB Charts , or run Spark jobs using MongoDB’s Spark Connector. For more complex data science and warehousing analytical queries, many enterprises choose the Databricks Lakehouse Platform . Enterprises can also benefit from enriching MongoDB data with data from other internal or external sources in the Databricks Lakehouse. The Databricks Lakehouse Platform combines the best elements of data lakes and data warehouses to deliver the reliability, strong governance, and performance of data warehouses with the openness, flexibility, and machine learning support of data lakes. This unified approach simplifies your modern data stack by eliminating the data silos that traditionally separate and complicate data engineering, analytics, BI, data science, and machine learning. With Databricks notebooks, developers and analytics teams can collaboratively write code in Python, R, Scala, and SQL, plus explore data with interactive visualizations and discover new insights. You can confidently and securely share code with co-authoring, commenting, automatic versioning, Git integrations, and role-based access controls. As good as MongoDB and Databricks are on their own, together we offer enterprises the unmatched ability to work with live application data across traditionally separate domains. This ability allows your teams to deliver what we call application-driven analytics . How does this work? Using MongoDB and Databricks together MongoDB and Databricks offer several ways to integrate the two systems, but the primary means is MongoDB’s Spark Connector. The Spark connector can be used within Databricks notebooks to directly query live application data managed in MongoDB collections and then loaded into data frames for further processing. You can also transform and/or enrich this data with data ingested from other sources using SparkSQL. Queries issued by the Spark Connector can be pushed down to MongoDB's aggregation framework and indexes for pre-processing, significantly improving query efficiency (measured in milliseconds not seconds or minutes). Result sets generated from the Databricks notebooks can then be inserted back into MongoDB collections or can be pushed into Delta Lake for long-running analytics and machine learning. Easier integration using Databricks' MongoDB Notebook A Databricks notebook is a web-based interface that contains runnable code, visualizations, and explanatory text in the form of paragraphs. It lets personas, such as data scientists and data engineers, build linked sets of code in different languages and visualize results in a format in which they are used to working. Notebooks are great for collaboration and can be easily iterated on and improved. MongoDB and Databricks created an example notebook that has sample code for: Reading the data from MongoDB Atlas collections as is into Spark dataframes. Pre-processing and filtering the data from Atlas collections using the aggregation framework, before passing into Spark dataframes. Enriching/transforming the data using SparkSQL Writing the enriched data back to the MongoDB Atlas collection. Figure 1:   Screenshot of data sources in a Databricks notebook. This notebook can help as an initial template for developers to start building complex transformation jobs on MongoDB data with Databricks platform. Interested in a practical example of how this works? Let's demonstrate how you can run analytics on a sample sales dataset using MongoDB's aggregation framework and visualize it with Charts. The example also explains how you can enrich this data using our Databricks notebook and load that back to MongoDB. Refer to the GitHub repo for the same. Figure 2:   Ways to integrate MongoDB and the Databricks Lakehouse Platform. In addition to Spark, MongoDB and Databricks provide seamless integration through shared Cloud Object stores to enable a more traditional data exchange using analytics-optimized formats such as Parquet, as well as event streaming integration using Apache Kafka. Together, MongoDB and Databricks offer unparalleled abilities to unify and process data from disparate systems in real-time. And now with the newly announced Databricks notebooks integration, data engineers and data scientists have an even easier and more intuitive interface to harness MongoDB data for their most sophisticated analytics and AI processing, making real-time applications more intelligent. Conclusion MongoDB Atlas along with Databricks Platform together will help organizations handle the increasing convergence between operational and analytical workloads. This convergence enables application-driven analytics and will help you build smarter applications and derive the right insights in real-time. Reach out to partners@mongodb.com to learn more.

5 Key Questions for App-Driven Analytics

Note: This article originally appeared in The New Stack . Data that powers applications and data that powers analytics typically live in separate domains in the data estate. This separation is mainly due to the fact that they serve different strategic purposes for an organization. Applications are used for engaging with customers while analytics are for insight. The two classes of workloads have different requirements—such as read and write access patterns, concurrency, and latency—therefore, organizations typically deploy purpose-built databases and duplicate data between them to satisfy the unique requirements of each use case. As distinct as these systems are, they're also highly interdependent in today's digital economy. Application data is fed into analytics platforms where it's combined and enriched with other operational and historical data, supplemented with business intelligence (BI), machine learning (ML) and predictive analytics, and sometimes fed back to applications to deliver richer experiences. Picture, for example, an ecommerce system that segments users by demographic data and past purchases and then serves relevant recommendations when they next visit the website. The process of moving data between the two types of systems is here to stay. But, today, that’s not enough. The current digital economy, with its seamless user experiences that customers have come to expect, requires that applications also become smarter, autonomously taking intelligent actions in real time on our behalf. Along with smarter apps, businesses want insights faster so they know what is happening “in the moment.” To meet these demands, we can no longer rely only on copying data out of our operational systems into centralized analytics stores. Moving data takes time and creates too much separation between application events and analytical actions. Instead, analytics processing must be “shifted left” to the source of the data—to the applications themselves. We call this shift application-driven analytics . And it’s a shift that both developers and analytics teams need to be ready to embrace. Find out why the MongoDB Atlas developer data platform was recently named a Leader in Forrester Wave: Translytical Data Platforms, Q4 2022 Defining required capabilities Embracing the shift is one thing; having the capabilities to implement it is another. In this article, we break down the capabilities required to implement application-driven analytics into the following five critical questions for developers: How do developers access the tools they need to build sophisticated analytics queries directly into their application code? How do developers make sense of voluminous streams of time series data? How do developers create intelligent applications that automatically react to events in real time? How do developers combine live application data in hot database storage with aged data in cooler cloud storage to make predictions? How can developers bring analytics into applications without compromising performance? To take a deeper dive into app-driven analytics—including specific requirements for developers compared with data analysts and real-world success stories—download our white paper: Application-Driven Analytics . 1. How do developers access the tools they need to build sophisticated analytics queries directly into their application code? To unlock the latent power of application data that exists across the data estate, developers rely on the ability to perform CRUD operations, sophisticated aggregations, and data transformations. The primary tool for delivering on these capabilities is an API that allows them to query data any way they need, from simple lookups to building more sophisticated data processing pipelines. Developers need that API implemented as an extension of their preferred programming language to remain "in the zone" as they work through problems in a flow state. Alongside a powerful API, developers need a versatile query engine and indexing that returns results in the most efficient way possible. Without indexing, the database engine needs to go through each record to find a match. With indexing, the database can find relevant results faster and with less overhead. Once developers start interacting with the database systematically, they need tools that can give them visibility into query performance so they can tune and optimize. Powerful tools like MongoDB Compass let users monitor real-time server and database metrics as well as visualize performance issues . Additionally, column-oriented representation of data can be used to power in-app visualizations and analytics on top of transactional data. Other MongoDB Atlas tools can be used to make performance recommendations , such as index and schema suggestions to further streamline database queries. 2. How do you make sense of voluminous streams of time series data? Time series data is typical in many modern applications. Internet of Things (IoT) sensor data, financial trades, clickstreams, and logs enable businesses to surface valuable insights. To help, MongoDB developed the highly optimized time series collection type and clustered indexes. Built on a highly compressible columnar storage format, time series collections can reduce storage and I/O overhead by as much as 70%. Developers need the ability to query and analyze this data across rolling time windows while filling any gaps in incoming data. They also need a way to visualize this data in real time to understand complex trends. Another key requirement is a mechanism that automates the management of the time series data lifecycle. As data ages, it should be moved out of hot storage to avoid congestion on live systems; however, there is still value in that data, especially in aggregated form to provide historical analysis. So, organizations need a systematic way of tiering that data into low-cost object storage in order to maintain their ability to access and query that data for the insights it can surface. 3. How do you create intelligent applications that automatically react to events in real time? Modern applications must be able to continuously analyze data in real time as they react to live events. Dynamic pricing in a ride-hailing service, recalculating delivery times in a logistics app due to changing traffic conditions, triggering a service call when a factory machine component starts to fail, or initiating a trade when stock markets move—these are just a few examples of in-app analytics that require continuous, real-time data analysis. MongoDB Atlas has a host of capabilities to support these requirements. With change streams , for example, all database changes are published to an API, notifying subscribing applications when an event matches predefined criteria. Atlas triggers and functions can then automatically execute application code in response to the event, allowing you to build reactive, real-time, in-app analytics. 4. How do you combine live application data in hot database storage with aged data in cooler cloud storage to make predictions? Data is increasingly distributed across different applications, microservices , and even cloud providers. Some of that data consists of newly ingested time-series measurements or orders made in your ecommerce store and resides in hot database storage. Other data sets consist of older data that might be archived in lower cost, object cloud storage. Organizations must be able to query, blend, and analyze fresh data coming in from microservices and IoT devices along with cooler data, APIs, and third-party data sources that reside in object stores in ways not possible with regular databases. The ability to bring all key data assets together is critical for understanding trends and making predictions, whether that's handled by a human or as part of a machine learning process. 5. How can you bring analytics into your applications without compromising their performance? Live, customer-facing applications need to serve many concurrent users while ensuring low, predictable latency and do it consistently at scale. Any slowdown degrades customer experience and drives customers toward competitors. In one frequently cited study, Amazon found that just 100 milliseconds of extra load time cost them 1% in sales . So, it's critical that analytics queries on live data don’t affect app performance. A distributed architecture can help you enforce isolation between the transactional and analytical sides of an application within a single database cluster . You can also use sophisticated replication techniques to move data to systems that are totally isolated but look like a single system to the app. Next steps to app-driven analytics As application-driven analytics becomes pervasive, the MongoDB Atlas developer data platform unifies the core data services needed to make smarter apps and improved business visibility a reality. Atlas does this by seamlessly bridging the traditional divide between transactional and analytical workloads in an elegant and integrated data architecture. With MongoDB Atlas, you get a single platform managing a common data set for both developers and analysts. With its flexible document data model and unified query interface, the Atlas platform minimizes data movement and duplication and eliminates data silos and architectural complexity while unlocking analytics faster and at lower cost on live operational data. It does all this while meeting the most demanding requirements for resilience, scale, and data privacy. For more information about how to implement app-driven analytics and how the MongoDB developer data platform gives you the tools needed to succeed, download our white paper, Application-Driven Analytics .

MongoDB World 2022 Recap — Performance Gotchas of Replicas Spanning Multiple Data Centers

Indeed has more than 25 million open jobs online at any one time. It stores more than 225 million resumes on Indeed systems, and it has 250 million unique users every month. Indeed operates enterprise-wide global clusters in the cloud across multiple availability zones all around the world, including the United States, Asia-Pacific, Europe, and Australia. Indeed is also a MongoDB super user. About 50% of everything Indeed does is built on MongoDB. In a recent session at MongoDB World 2022, Indeed senior cloud database engineer Alex Leong shared real-world experiences of performance issues when spanning replica sets across multiple data centers. He also covered how to identify these issues and, most importantly, how to fix them. This article provides highlights from Leong’s presentation, including dealing with changes in sync sources, replication lags, and more. Resilience and performance Indeed maintains multiple data centers for resiliency. Having multiple data centers ensures there's no single point of failure and keeps data in close proximity to job seekers' locations. This approach facilitates faster response times and better overall end user experience. Running multiple data centers can introduce other performance issues, however. One issue involves the initial sync of new nodes in the system, which needs to happen as quickly as possible to avoid returning stale data. Write concern is a critical consideration because, if there's an interruption on a primary node and a failover to a secondary, when you eventually roll back to the primary, any changes that were captured on the secondary while the system was running in failover mode must be preserved. Also, when you're running multiple data centers, changes in sync sources can occur that go unnoticed. Replication lags can occur when data centers are located far apart from each other. Overriding sync sources When you have an environment with hundreds of millions of users and enormous volumes of data spanning several geographic regions, spinning up and synchronizing a new node in a replica set creates logistical hurdles. To start, you have to decide where the new node syncs from. It seems logical that the default decision would be to sync with the nearest node. But, as Leong said in his session, at times you may not get the nearest sync source, and you may have to override the default sync source to choose the best one. This decision needs to be made early, Leong said, because doing so later means any progress you've made toward syncing the new node will have been wasted. Replication lags Replication lags can occur between the primary and secondary nodes for several reasons, including downtime (planned or unplanned) on the primary server, a network failure, or disk failure. Whatever the reason, there are ways to speed things up. In his session, Leong illustrates how to use the WiredTiger cache size to accelerate replication between nodes. Changes in sync sources Leong uses the term sync topology to describe how primary and secondary nodes are configured for syncing data between them. In some scenarios, a secondary node can change its sync source (sync topology) from one node to another, perhaps because the first node was busy at the time. MongoDB makes this change automatically, and it might not be noticed without looking at the log. Fixing cross-data center write concerns According to Leong, when write performance decreases, 99% of the time it's because of a change in sync sources. To be proactive, Leong creates a write performance monitor to identify and self-heal decreases in write performance so he doesn't have to find out the hard way (from users). Other critical performance issues covered in the session include chained replication , which is the process by which secondary nodes replicate from node to node, changing write concern when a secondary node goes down, and how to configure write concerns across Availability Zones in AWS.
