Goodnotes Finds Marketplace Success Using MongoDB Atlas
In the fast-paced world of app development, creating a feature-rich digital marketplace that scales effectively can be challenging. Goodnotes was founded in 2010 with the aim of replacing traditional paper notebooks with a digital alternative that reimagines the note-taking experience. Since then, the app has gone through several iterations and grown in popularity, now with more than 24 million monthly active users and 2.5 billion notes. The team behind Goodnotes spoke at MongoDB.local Hong Kong in September 2024. They shared their journey of using MongoDB Atlas and MongoDB Atlas Search to build and run a comprehensive marketplace that expands the company’s offerings, catering to its growing number of content creators. “At the beginning of 2023, we launched a pop-up shop, which was a very simple version of the marketplace, to test the water, and we realized it got really popular,” said Xing Dai, Principal Backend Engineer at Goodnotes. The full Goodnotes Marketplace launched in August 2024 as a space where content creators can enhance their note-taking experience by purchasing additional content, such as planners, stickers, and textbooks. Building a robust digital marketplace with MongoDB Atlas “The first and the most difficult challenge [was] that we are a multiplatform app, and if you want to launch on multiple platforms, you need to support different app stores as well as [the] web,” said Dai. Using MongoDB Atlas, Dai’s team created a fully configurable marketplace that would be accessible on different mobile and desktop platforms and the web. The initial pop-up shop’s infrastructure consisted of a Payload content management system connected to a MongoDB database. However, building a full-fledged marketplace was more challenging. The architecture needed to be scalable and include search, ordering, and customization capabilities. “With [MongoDB] Atlas, it was really easy to add the in-app purchase and build the subscription infrastructure to manage the purchase workflow,” said Dai. The Goodnotes team introduced NestJS—a JavaScript API framework—to build client APIs. It then developed a user-friendly portal for the operations team and for creators who want to upload new products. Finally, the team built a full event-based data pipeline on top of MongoDB. “What’s nice is that everything on the marketplace is actually configurable in the backend,” said Dai. “We don’t need to do anything other than configuring what we need to store in the database, and the iOS client will connect it to the backend.” “When we want to extend the marketplace to other platforms, nothing needs to be changed,” Dai added. “We only need to configure different shops for different platforms.” This means that Goodnotes can easily make its marketplace available on different app platforms, such as Apple and Android, and on the web. Adding searches, charts, and soon AI As Goodnotes added more products to its marketplace, users had difficulty finding what they wanted. Despite having limited resources, the Goodnotes team endeavored to build a comprehensive search function. Using MongoDB Atlas Search and MongoDB Atlas Triggers , the team built a search function that would generate the search view collection by products and attributes, combining them into one collection. The team then added an Atlas Search index for the search field with an API exposing the search. “We also added an auto-complete function, which is very similar to search, in the sense that we just had to create a function to generate aggregated collections, trigger it using [MongoDB] Atlas Triggers, and add the index and expose it in the marketplace,” said Dai. The search function is now popular among marketplace users, making it quick and easy for them to find what they are looking for. Goodnotes also regularly uses MongoDB Atlas Charts . For example, it creates charts showing how many products there are in the system over time. One of the key next steps for Goodnotes involves using generative AI to translate product descriptions and content into different languages (the app is currently available in 11 languages). The team also wants to introduce personalized recommendations for a more tailored experience for each user. Ending the MongoDB.local presentation, Dai said: “MongoDB made it very fast and easy to build the whole marketplace and our search feature on top of the database using [MongoDB] Atlas Search. The solution scales, and so far we haven’t had any performance issues.” Visit our product page to learn more about MongoDB Atlas .
Managing Data Corruption in the Cloud
Key Takeaways Silent data corruption—rare events in which data becomes corrupt in a way that is not readily detected—can impact systems of all kinds across the software industry. MongoDB Atlas, our global cloud database service, operates at petabyte scale, which requires sophisticated solutions to manage the risk of silent data corruption. Because MongoDB Atlas itself relies on cloud services, the systems we have engineered to safeguard customer data have to account for limited access to the physical hardware behind our infrastructure. The systems we have implemented consist of software-level techniques for proactively detecting and repairing instances of silent data corruption. These systems include monitoring for checksum failures and similar runtime evidence of corrupt data, methods of identifying corrupt documents by leveraging MongoDB indexes and replication, and processes for repairing corrupt data by utilizing the redundant replicas. Introduction: Hardware corruption in the cloud As a cloud platform, MongoDB Atlas promises to free its customers from the work of managing hardware. In our time developing Atlas, however, some hardware problems have been challenging to abstract away. One of the most notable of these is silent data corruption. No matter how well we design our software, in rare cases hardware can silently fail in ways that compromise data. Imagine, for example, a distance sensor that detects an obstacle 10 meters away. Even if the many layers of software handling the sensor’s data function flawlessly (application, network, database, operating system, etc.), if an unlucky memory chip has a single bit flipped by radiation the value of this measurement could mutate to something like 26. 1 The consequences of this botched measurement would depend on how this data is used: in some cases it may introduce a blip in a vast amount of research data, 2 but in the wrong system it could be dangerous. Despite the rarity of events like this, global cloud systems like MongoDB Atlas operate at such a scale that these events become statistically inevitable over time, even in the presence of existing manufacturer defect screening. Our platform currently stores petabytes of data and operates nearly half a million virtual machines in cloud datacenters in dozens of countries; even random failures with odds as low as one in a hundred thousand become likely to appear in such an environment. Complicating this further is the reality that silent data corruption has many possible causes beyond rare, random failures like the example of radiation above. Recent research has identified notable rates of data corruption originating from defective CPUs in large-scale data centers, 3 and corruption can just as easily originate from bugs in operating systems or other software. Considering this scope, and with limited levels of access to the cloud hardware we use to power MongoDB Atlas, how can we best stay ahead of the inevitability of silent data corruption affecting customers on our platform? Our response to this problem has been to implement features both in the MongoDB database and the orchestration software that powers MongoDB Atlas for continuously detecting and repairing silent data corruption. Our systems are designed to be proactive, identifying potential issues before they ever affect customer data or operations. The way we use these systems can be described in three steps. First, Atlas proactively monitors for signals of corrupt data from across our fleet of databases by checking for certain logical truths about data in the course of runtime operations. Then, in the case that evidence of corruption is identified, we utilize features in MongoDB for scanning databases to pinpoint the location of corrupt data, narrowing down the site of corruption to specific documents. Finally, once we have enough information to identify a remediation plan, we repair corruption in coordination with our customers by leveraging the redundancy of MongoDB’s replica set deployment model. As a whole this approach gives us early visibility into new types of data corruption that emerge in our fleet, as well as the tools we need to pinpoint and repair corruption when it occurs. Proactively monitoring for evidence of corruption Fortunately for anyone interested in managing silent data corruption at scale, databases tend to tell you a lot about what they observe. In the course of a single day, the hundreds of thousands of database processes in the Atlas fleet generate terabytes of database logs describing their operations: connections received from clients, the details of startup and shutdown procedures, queries that are performing poorly. At their worst, logs at this scale can be expensive to store and difficult to parse, but at their best they are an indispensable diagnostic tool. As such, the first step of our strategy for managing corruption in Atlas is strategic log management. There are several points in the course of a MongoDB database’s operations where we can proactively validate logical assumptions about the state of data and emit messages if something appears to be corrupt. The most fundamental form of this validation we perform is checksum validation. A checksum is a very small piece of information that is deterministically generated from a much larger piece of information by passing it through a mathematical function. When the storage engine for an Atlas cluster writes data to disk, each block–or individual unit of data written–is accompanied by a checksum of the data. When that block is later read from disk, the storage engine once again passes the data through the checksum function and verifies that the output matches the checksum that was originally stored. If there is a mismatch, we have a strong reason to suspect that the stored information is corrupt; the database process then emits a log line indicating this and halts further execution. You can see this behavior in the MongoDB source code here . Figure 1: Checksum validation fails after corruption is introduced on the disk level. In addition to checksums, there are other opportunities for checking basic assumptions about the data we are handling during routine MongoDB operations. For example, when iterating through a list of values that is expected to be in ascending order, if we find that a given value is actually less than the one that preceded it we can also reasonably suspect that a piece of information is corrupt. Similar forms of validation exist in dozens of places in the MongoDB database. Successfully leveraging these types of runtime errors in the context of the entire Atlas fleet, however, comes with some challenges. We need to quickly detect these messages from among the flood of logs generated by the Atlas fleet, and, importantly, do so in a way that maintains data isolation for the many individual customer applications running on Atlas. Database logs, by design, reveal a lot about what is happening in a system; as the creators of a managed database service, exposing the full contents of database logs to our employees for corruption analysis is a non-starter, and so we need a more nuanced method of detecting these signals. To solve this problem, we implemented a system for detecting certain classes of error as Atlas database logs are generated and emitting high-level metadata that can be analyzed by our teams internally without revealing sensitive information about the content or operations of a given database. To describe this system, it is first useful to understand a pair of concepts that we often reference internally, and which play an important role in the development of the Atlas platform, the data plane and the control plane. The data plane describes the systems that manage the data that resides in a given Atlas cluster. It consists of the virtual network containing the cluster’s resources, the virtual machines and related resources hosting the cluster’s database processes, and storage for diagnostic information like database logs. As a whole, it consists of many thousands of individual private networks and virtual machines backing the Atlas fleet of database clusters. The control plane, on the other hand, is the environment in which the Atlas management application runs. It consists of separate networks hosting our own application processes and backing databases, and stores all of the operational metadata required for running Atlas including, for example, metadata about the configurations of the clusters that constitute the Atlas fleet. Figure 2: An Agent observes log line indicative of data corruption and communicates this to to the Atlas Control Plane. The flow of information between the two planes only occurs on a limited set of vectors, primary among these being the MongoDB Agent, a background process that runs locally on virtual machines in the Atlas data plane. The Agent serves as the primary orchestrator of a cluster’s database processes. Whenever an Atlas customer requests a change to their cluster–for example, upgrading the version of their database–their request results in some modification to metadata that resides in the control plane which is then picked up by the Agents in the data plane. The Agents then begin to interact with the individual database processes of the cluster to bring them to the desired state. The Agent, with its ability to access database logs inside the data plane, provides the tool we need to detect critical logs in a controlled manner. In fact, at the time we implemented the feature for ingesting these logs, the Agent was already capable of tailing MongoDB logs in search of particular patterns. This is how the Performance Advisor feature works, in which the Agent looks for slow query logs above a certain operation duration threshold to alert users of potentially inefficient data queries. For the purposes of corruption detection we introduced a new feature for defining additional log patterns for the Agent to look for: for example, a pattern that matches the log line indicating an invalid checksum when data is read from disk. If the Agent observes a line that matches a specified pattern it will send a message to the control plane reporting when the message was observed, in which process, along with high-level information–such as an error code–but without further information about the activity of the cluster. The next step of this process, once evidence of corruption is detected, is to assess the extent of the problem and gather additional information to inform our response. This brings us to the next piece of our corruption management system: once we become aware of the possibility of corruption, how do we pinpoint it and determine a remediation plan? Scanning databases to pinpoint identified corruption So far, we have outlined our system for detecting runtime errors symptomatic of corrupt data. However, the detection of these errors by itself is not sufficient to fully solve the problem of data corruption in a global cloud database platform. It enables early awareness of potential corruption within the Atlas fleet, but when it is time to diagnose and treat a specific case we often need more exhaustive tools. The overall picture here is not unlike the treatment of an illness: so far, what we have described is our system for detecting symptoms. Once symptoms have been identified, further testing may be needed to determine the correct course of treatment. In our case, we may need to perform further scanning of data to identify the extent of corruption and the specific information affected. The ability to scan MongoDB databases for corruption relies on two of the most fundamental concepts of a database, indexes and replication . These two basic features of MongoDB each come with certain simple logical assumptions that they adhere to in a healthy state. By scanning for specific index entries or replicated data that violate these assumptions, we are able to pinpoint the location of corrupt data, a necessary step towards determining a remediation path. Indexes–data structures generated by a database to allow for quick lookup of information–relate to the contents of a database following specific logical constraints. For example, if a given collection is using an index on the lastName field and contains a document with a lastName value of “Turing,” the value “Turing” should be present in that collection’s index keys. A violation of this constraint, therefore, could point to the location of corrupt data; the absence of an in-use lastName value in the index would indicate that either the index has become corrupt or the lastName value on the document itself has become corrupt. Because almost all indexes are specified by the customer, Atlas does not have control over how the data in a cluster is indexed. In practice, though, the most frequently-accessed data tends to be highly indexed, making index scanning a valuable tool in validating the most critical data in a cluster. Replicated data, similarly, adheres to certain constraints in a healthy state: namely, that replicas of data representing the same point in time should be identical to one another. As such, replicated data within a database can also be scanned at a common point in time to identify places where data has diverged as a result of corruption. If two of three replicas in a cluster show a lastName value of “Turing” for a given document but the third shows “Toring” 4 , we have a clear reason to suspect that this particular document’s data has become corrupt. Since all Atlas clusters are deployed with at least three redundant copies of data, replication is always available to be leveraged when repairing corruption on Atlas. This is, of course, easier said than done. In practice, performing integrity scanning of indexes and replicated data for a very large database requires processing a large amount of complex data. In the past, performing such an operation was often infeasible on a database cluster that was actively serving reads and writes. The db.collection.validate command was one of the first tools we developed at MongoDB for performing integrity scans of index data, but it comes with certain restrictions. The command obtains an exclusive lock on the collection it is validating, which means it will block reads and writes on the collection until it is finished. We still use this command as part of our corruption scanning strategy, but because of its limitations this means it is often only feasible to run on an offline copy of a database restored from a backup snapshot. This can be expensive, and comes with the overhead of managing additional hardware for performing validations on offline copies. With this in mind, we have been developing new tools for scanning for data corruption that are more feasible to run in the background of a cluster actively serving traffic. Our latest tools for detecting inconsistencies in replica sets utilize the replication process to perform background validation of data while a cluster is processing ordinary operations, and can be rate-limited based on the available resources on the cluster. When this process is performed, the primary node will begin by iterating through a collection in order, pulling a small batch of data into memory that stays within the bounds of a specified limit. It will make note of the range of the data being analyzed and produce an MD5 hash , writing this information to an entry in the oplog , a transaction log maintained by MongoDB that is replayed by secondary nodes in the database. When the secondaries of the cluster encounter this entry in their copies of the oplog, they perform the same calculation based on their replicas of the data, generating their own hash belonging to the indicated range of data at the specified point in time. By comparing a secondary’s hash with the original hash recorded by the primary, we can determine whether or not this batch of data is consistent between the two nodes. The result of this comparison (consistent or inconsistent) is then logged to an internal collection in the node’s local database . In this manner small batches of data are processed until the collection has been fully scanned. Figure 3: Data consistency between replicas is validated by leveraging the oplog. This form of online data consistency scanning has allowed us to scan our own internal databases without interruption to their ordinary operations, and is a promising tool for expanding the scale of our data corruption scanning without needing to manage large amounts of additional hardware for performing offline validations. We do, nonetheless, recognize there will be some cases where running an online validation may be unviable, as in the cases of clusters with very limited available CPU or memory. For this reason, we continue to utilize offline validations as part of our strategy, trading the cost of running additional hardware for the duration of the validation for complete isolation between the validation workload and the application workload. Overall, utilizing both online and offline approaches in different cases gives us the flexibility we need to handle the wide range of data characteristics we encounter. Repairing corruption Once the location of corrupt data has been identified, the last step in our process is to repair it. Having several redundant copies of data in an Atlas cluster means that more often than not it is straightforward to rebuild the corrupt data. If there is an inconsistency present on a given node in a cluster, that node can be rebuilt by triggering an initial sync and designating a known healthy member as the sync source. Triggering this type of resync is sufficient to remediate both index inconsistencies and replication inconsistencies 5 as long as there is at least one known, healthy copy of data in a cluster. While it is typically the case that it is straightforward to identify a healthy sync source when repairing corruption–truly random failures would be unlikely to happen on more than one copy of data–there are some additional considerations we have to make when identifying a sync source. A given node in an Atlas cluster may have already had its data resynced at some point in the past in the course of ordinary operations. For example, if the cluster was migrated to a new set of hardware in the past, some or all nodes in the cluster may have already been rebuilt at least once before. For this reason, it is important for us to consider the history of changes in the cluster in the time after corruption may have been introduced to rule out any nodes that may have copied corrupt data, and to separately validate the integrity of the sync source before performing any repair. Once we are confident in a remediation plan and have coordinated any necessary details with our customers, we leverage internal features for performing automated resyncs on Atlas clusters to rebuild corrupt data. Very often, these repairs can be done with little interruption to a database’s operations. Known healthy nodes can continue to serve application traffic while data is repaired in the background. Internal-facing functionality for repairing Atlas clusters has existed since the early days of the platform, but in recent years we have added additional features and levels of control to facilitate corruption remediation. In particular, in many cases we are able to perform optimized versions of the initial sync process by using cloud provider snapshots of healthy nodes to circumvent the sometimes-lengthy process of copying data directly between replica set members, reducing the overall time it takes to repair a cluster. In the rarer event that we need to perform a full logical initial sync of data, we can continue to perform this mode of data synchronization as well. After repair has completed, we finish by performing follow-up scanning to validate that the repair succeeded. We are still hard at work refining our systems for detecting and remediating data corruption. At the moment, much of our focus is on making our scanning processes as performant and thorough as possible and continuing to reduce the time it takes to identify new instances of corruption when they occur. With these systems in place it is our intention to make silent data corruption yet another detail of hardware management that the customers of Atlas don’t need to lose any sleep over, no matter what kinds of rare failures may occur.

"Silent data corruptions at scale." arXiv preprint arXiv:2102.11245 (2021). 4 In practice, it is rare that corrupt data results in a legible value; more often data in this state would be simply illegible. 5 There are other methods of rebuilding indexes in a MongoDB database beyond what is described here; see db.collection.reIndex for information on rebuilding indexes without triggering an initial sync.
What’s New From MongoDB at AWS re:Invent 2024
As thousands of attendees make their way home after a week in Vegas—a week packed with learning, product launches, and round-the-clock events—we thought we’d reflect on the show’s highlights. MongoDB was excited to showcase our latest integrations and solutions with Amazon Web Services (AWS), which range from new ways to optimize generative AI, to faster, more cost-effective methods for modernizing applications. But first, we want to thank our friends at AWS for recognizing MongoDB as the AWS Technology Partner of the Year NAMER! This prestigious award recognizes AWS Technology Partners that are using AWS to lower costs, increase agility, and innovate faster. Announced during the re:Invent Partner Awards Gala, the Technology Partner of the Year Award is a testament to the specialization, innovation, and cooperation MongoDB and AWS have jointly brought to customers this year. In addition, MongoDB also received AWS Partner of the Year awards for Italy, Turkey, and Iberia. These awards follow wins in the ASEAN Global Software Partner of the Year and Taiwan Technology Partner of the Year categories earlier in the year, further demonstrating the global reach and popularity of the world’s most popular document database! Harnessing the potential of gen AI If 2024 (and 2023, and 2022…) was the year of gen AI excitement, then 2025 may turn out to be marked by realistic gen AI implementation. Indeed, we’ve seen customers shift their 2025 AI focus toward optimizing resource-intensive gen AI workloads to drive down costs—and to get the most out of this groundbreaking technology. Retrieval-augmented generation (RAG), one of the main ways companies use their data to customize the output of foundation models, has become the focus of this push for optimization. Customers are looking for easier ways to fine-tune their RAG systems, asking questions like, “How do I evaluate the efficiency and accuracy of my current RAG workflow?” To that end, AWS and MongoDB are introducing new services and technologies for enterprises to optimize RAG architecture compute costs, while also maintaining accuracy. First up is vector quantization. By reducing vector storage and memory requirements while preserving performance, these capabilities empower developers to build AI-enriched applications with more scale—and at a lower cost. Leading foundation models like Amazon Titan are already compatible with vector quantization, helping to maintain high accuracy of generated responses while simultaneously reducing costs. You can read more about vector quantization on our blog. As for RAG evaluation, AWS has launched a new feature for Amazon Bedrock called, naturally, RAG Evaluator. This tool allows Bedrock users to evaluate and monitor RAG Apps natively within the Bedrock environment, eliminating the need for third-party frameworks to run tests and comparisons. As a Knowledge Base for Amazon Bedrock, MongoDB Atlas is ready on day one to take advantage of Bedrock RAG Evaluator, allowing companies to gauge and compare the quality of their RAG Apps across different applications. The RAG Evaluator, built on several joint integrations and solutions AWS and MongoDB released in 2024, and vector quantization together can streamline the deployment of enterprise generative AI. For example, in October MongoDB, Anthropic, and AWS announced a joint solution to create a memory-enhanced AI agent . Together, the three partners offer enterprise-grade, trusted, secure technologies to build generative AI apps quickly and flexibly using a family of foundation models in a fully managed environment. Overall, MongoDB and AWS are making it easier—and more cost-effective—for developers to build innovative applications that harness the full potential of generative AI on AWS. From cars to startups to glue MongoDB and AWS have been hard at work on a number of other solutions for developers across industries. Here’s a quick roundup: AWS Amplify + AppSync + MongoDB For startups, or for any organization looking to quickly test and launch applications, speed is everything. That’s why MongoDB teamed up with AWS to create a full-stack solution that provides developers with the same high standards of performance and scalability they would demand for any app. By combining AWS Amplify, AWS AppSync, and MongoDB Atlas, AWS and MongoDB have created a full-stack solution that enables seamless front-end development, robust and scalable backend services, out-of-the-box CI/CD, and a flexible and powerful database solution, allowing developers to drastically reduce the coding time required to launch new applications. Check out this tutorial and repository for a starter template . Digital twins on AWS CMS For those in the automotive sector, MongoDB and AWS have developed a connected mobility solution to help remove the undifferentiated integration, or “technical plumbing” work, of connecting vehicles to the cloud. When used together, Connected Mobility Solution (CMS) on AWS and MongoDB Atlas help accelerate the development of next-generation digital twin use cases and applications, including connected car use cases. MongoDB’s document model allows easy and flexible modeling and storage of connected vehicle sensor data. Read our joint blog with AWS to learn how the MongoDB Atlas document model helps with data modeling of connected vehicles data and how this capability can be leveraged via AWS Automotive Cloud Developer Portal (ACDP). AWS Glue + MongoDB Atlas Speaking of undifferentiated plumbing, MongoDB Atlas is now integrated into AWS Glue’s visual interface. The new integration simplifies data integration between MongoDB Atlas and AWS, making it easy to build efficient ETL (Extract, Transform, Load) pipelines with minimal effort. With its visual interface, AWS Glue allows users to seamlessly transfer, transform, and load data to and from MongoDB Atlas without needing deep technical expertise in Spark or SQL. In this blog post , we look at how AWS Glue and MongoDB Atlas can transform the way you manage data movement. Buy with AWS In the spirit of making things easier for our joint customers, in early 2025 MongoDB will also join the AWS ‘Buy with AWS’ program. Once up and running, Buy With AWS will allow customers to pay for Atlas using their AWS account directly from the Atlas UI, further reducing friction for customers wanting to get started with Atlas on AWS. New Atlas Updates Announced at re:Invent Aside from our joint endeavors with AWS, MongoDB has also been hard at work on improving the core Atlas platform. Here’s an overview of what we announced: Asymmetrical sharding support for Terraform Atlas Provider Customers are constantly seeking ways to optimize costs to ensure they get the best value for their resources. With Asymmetrical Sharding, now available in the Terraform MongoDB Atlas Provider, MongoDB Atlas users can customize the Cluster Tier and IOPS for each shard, encouraging better resource allocation, improved operational efficiency, and cost savings as customer needs evolve. Atlas Flex Tier Our new Atlas Flex tier offers the scaled flexibility of serverless, with the cost-capped assurance of shared tier clusters. With Atlas Flex Tier, developers can build and scale applications cost-effectively without worrying about runaway bills or resource provisioning. New test bench feature in Query Converter At MongoDB, we firmly believe that the document model is the best way for customers to build applications with their data. In our latest update to Relational Migrator , we’ve introduced Generative AI to automatically convert SQL database objects and validate them using the test bench in a fraction of the time, producing deployment-ready code up to 90% faster. This streamlined approach reduces migration risks and manual development effort, enabling fast, efficient, and precise migrations to MongoDB.

AI-Powered Call Centers: A New Era of Customer Service
Customer satisfaction is critical for insurance companies. Studies have shown that companies with superior customer experiences consistently outperform their peers. In fact, McKinsey found that life and property/casualty insurers with superior customer experiences saw a significant 20% and 65% increase in Total Shareholder Return , respectively, over five years. A satisfied customer is a loyal customer. They are 80% more likely to renew their policies, directly contributing to sustainable growth. However, one major challenge faced by many insurance companies is the inefficiency of their call centers. Agents often struggle to quickly locate and deliver accurate information to customers, leading to frustration and dissatisfaction. This article explores how Dataworkz and MongoDB can transform call center operations. By converting call recordings into searchable vectors (numerical representations of data points in a multi-dimensional space), businesses can quickly access relevant information and improve customer service. We'll dig into how the integration of Amazon Transcribe, Cohere, and MongoDB Atlas Vector Search—as well as Dataworkz's RAG-as-a-service platform— is achieving this transformation. From call recordings to vectors: A data-driven approach Customer service interactions are goldmines of valuable insights. By analyzing call recordings, we can identify successful resolution strategies and uncover frequently asked questions. In turn, by making this information—which is often buried in audio files— accessible to agents, they can give customers faster and more accurate assistance. However, the vast volume and unstructured nature of these audio files make it challenging to extract actionable information efficiently. To address this challenge, we propose a pipeline that leverages AI and analytics to transform raw audio recordings into vectors as shown in Figure 1: Storage of raw audio files: Past call recordings are stored in their original audio format Processing of the audio files with AI and analytics services (such as Amazon Transcribe Call Analytics ): speech-to-text conversion, summarization of content, and vectorization Storage of vectors and metadata: The generated vectors and associated metadata (e.g., call timestamps, agent information) are stored in an operational data store Figure 1: Customer service call insight extraction and vectorization flow Once the data is stored in vector format within the operational data store, it becomes accessible for real-time applications. This data can be consumed directly through vector search or integrated into a retrieval-augmented generation (RAG) architecture, a technique that combines the capabilities of large language models (LLMs) with external knowledge sources to generate more accurate and informative outputs. Introducing Dataworkz: Simplifying RAG implementation Building RAG pipelines can be cumbersome and time-consuming for developers who must learn yet another stack of technologies. Especially in this initial phase, where companies want to experiment and move fast, it is essential to leverage tools that allow us to abstract complexity and don’t require deep knowledge of each component in order to experiment with and realize the benefits of RAG quickly. Dataworkz offers a powerful and composable RAG-as-a-service platform that streamlines the process of building RAG applications for enterprises. To operationalize RAG effectively, organizations need to master five key capabilities: ETL for LLMs: Dataworkz connects with diverse data sources and formats, transforming the data to make it ready for consumption by generative AI applications. Indexing: The platform breaks down data into smaller chunks and creates embeddings that capture semantics, storing them in a vector database. Retrieval: Dataworkz ensures the retrieval of accurate information in response to user queries, a critical part of the RAG process. Synthesis: The retrieved information is then used to build the context for a foundational model, generating responses grounded in reality. Monitoring: With many moving parts in the RAG system, Dataworkz provides robust monitoring capabilities essential for production use cases. Dataworkz's intuitive point-and-click interface (as seen in Video 1) simplifies RAG implementation, allowing enterprises to quickly operationalize AI applications. The platform offers flexibility and choice in data connectors, embedding models, vector stores, and language models. Additionally, tools like A/B testing ensure the quality and reliability of generated responses. This combination of ease of use, optionality, and quality assurance is a key tenet of Dataworkz's "RAG as a Service" offering. Diving deeper: System architecture and functionalities Now that we’ve looked at the components of the pre-processing pipeline, let’s explore the proposed real-time system architecture in detail. It comprises the following modules and functions (see Figure 2): Amazon Transcribe , which receives the audio coming from the customer’s phone and converts it into text. Cohere ’s embedding model, served through Amazon Bedrock , vectorizes the text coming from Transcribe. MongoDB Atlas Vector Search receives the query vector and returns a document that contains the most semantically similar FAQ in the database. Figure 2: System architecture and modules Here are a couple of FAQs we used for the demo: Q: “Can you explain the different types of coverage available for my home insurance?” A: “Home insurance typically includes coverage for the structure of your home, your personal belongings, liability protection, and additional living expenses in case you need to temporarily relocate. I can provide more detailed information on each type if you'd like.” Q: “What is the process for adding a new driver to my auto insurance policy?" A: “To add a new driver to your auto insurance policy, I'll need some details about the driver, such as their name, date of birth, and driver's license number. We can add them to your policy over the phone, or you can do it through our online portal.” Note that the question is reported just for reference, and it’s not used for retrieval. The actual question is provided by the user through the voice interface and then matched in real-time with the answers in the database using Vector Search. This information is finally presented to the customer service operator in text form (see Fig. 3). The proposed architecture is simple but very powerful, easy to implement, and effective. Moreover, it can serve as a foundation for more advanced use cases that require complex interactions, such as agentic workflows , and iterative and multi-step processes that combine LLMs and hybrid search to complete sophisticated tasks. Figure 3: App interface, displaying what has been asked by the customer (left) and how the information is presented to the customer service operator (right) This solution not only impacts human operator workflows but can also underpin chatbots and voicebots, enabling them to provide more relevant and contextual customer responses. Building a better future for customer service By seamlessly integrating analytical and operational data streams, insurance companies can significantly enhance both operational efficiency and customer satisfaction. Our system empowers businesses to optimize staffing, accelerate inquiry resolution, and deliver superior customer service through data-driven, real-time insights.

Better Digital Banking Experiences with AI and MongoDB
Interactive banking represents a new era in financial services where customers engage with digital platforms that anticipate, understand, and meet their needs in real-time. This approach encompasses AI-driven technologies such as chatbots, virtual assistants, and predictive analytics that allow banks to enhance digital self-service while delivering personalized, context-aware interactions. According to Accenture’s 2023 consumer banking study , 44% of consumers aged 18-44 reported difficulty accessing human support when needed, underscoring the demand for more responsive digital solutions that help bridge this gap between customers and financial services. Generative AI technologies like chatbots and virtual assistants can fill this need by instantly addressing inquiries, providing tailored financial advice, and anticipating future needs. This shift has tremendous growth potential; the global chatbot market is expected to grow at a CAGR of 23.3% from 2023 to 2030 , with the financial sector experiencing the fastest growth rate of 24.0%. This shift is more than just a convenience; it aims to create a smarter, more engaging, and intuitive banking journey for every user. Simplifying self-service banking with AI Navigating daily banking activities like transfers, payments, and withdrawals can often raise immediate questions for customers: “Can I overdraft my account?” “What will the penalties be?” or “How can I avoid these fees?” While the answers usually lie within the bank’s terms and conditions, these documents are often dense, complex, and overwhelming for the average user. At the same time, customers value their independence and want to handle their banking needs through self-service channels, but wading through extensive fine print isn't what they signed up for. By integrating AI-driven advisors into the digital banking experience, banks can provide a seamless, in-app solution that delivers instant, relevant answers. This removes the need for customers to leave the app to sift through pages of bank documentation in search of answers, or worse, endure the inconvenience of calling customer service. The result is a smoother and user-friendly interaction, where customers feel supported in their self-service journey, free from the frustration of navigating traditional, cumbersome information sources. The entire experience remains within the application, enhancing convenience and efficiency. Solution overview This AI-driven solution enhances the self-service experience in digital banking by applying Retrieval-Augmented Generation (RAG) principles, which combine the power of generative AI with reliable information retrieval, ensuring that the chatbot provides accurate, contextually relevant responses. The approach begins by processing dense, text-heavy documents, like terms and conditions, often the source of customer inquiries. These documents are divided into smaller, manageable chunks vectorized to create searchable data representations. Storing these vectorized chunks in MongoDB Atlas allows for efficient querying using MongoDB Atlas Vector Search , making it possible to instantly retrieve relevant information based on the customer’s question. Figure 1: Detailed solution architecture When a customer inputs a question in the banking app, the system quickly identifies and retrieves the most relevant chunks using semantic search. The AI then uses this information to generate clear, contextually relevant answers within the app, enabling a smooth, frustration-free experience without requiring customers to sift through dense documents or contact support. Figure 2: Leafy Bank mock-up chatbot in action How MongoDB supports AI-driven banking solutions MongoDB offers unique capabilities that empower financial institutions to build and scale AI-driven applications.

Customer Service Expert Wati.io Scales Up on MongoDB
Wati.io is a software-as-a-service (SaaS) platform that empowers businesses to develop conversation-driven strategies to boost growth. Founded by CEO Ken Yeung in 2019, Wati started as a chatbot solution for large enterprises, such as banks and insurance companies. However, over time, Yeung and his team noticed a growing need among small and medium-sized businesses (SMBs) to manage customer conversations more effectively. To address this need, Wati used MongoDB Atlas and built a solution based on the WhatsApp Business API. It enables businesses to manage and personalize conversations with customers, automate responses, improve commerce functions, and enhance customer engagement. Speaking at MongoDB.local Hong Kong in September 2024, Yeung said, “The current solutions on the market today are not good enough. Especially for SMBs [that] don’t have the same level of resources as enterprises to deal with the number of conversations and messages that need to be handled every day.” Supporting scale: From MongoDB Community Edition to MongoDB Atlas “From the beginning, we relied on MongoDB to handle high volumes of messaging data and enable businesses to manage and scale their customer interactions efficiently,” said Yeung. Wati originally used MongoDB Community Edition , as the company saw the benefits of a NoSQL model from the beginning. As the company grew, it realized it needed a scalable infrastructure, so Wati transitioned to MongoDB Atlas. “When we started reaching the 2 billion record threshold, we started having some issues. Our system slowed down, and we were not able to scale it,” said Yeung. Atlas has now become an essential part of Wati’s infrastructure, helping the company store and process millions of messages each month for over 10,000 customers in 165 countries. “Transitioning to a new platform—MongoDB Atlas—seamlessly was critical because our messaging system needs to be on 24/7,” said Yeung. Wati collaborated closely with the MongoDB Professional Services and MongoDB Support teams, and in a few months it was able to rearchitect the deployment and data model for future growth and demand. The work included optimizing Wati’s database by breaking it down into clusters. Wati then focused on extracting connections, such as conversations, and dividing and categorizing data within the clusters—for example, qualifying data as cold or hot based on the read and write frequencies. This architecture underpins the platform’s core features, including automated customer engagement, lead qualification, and sales management. Deepening search capabilities with MongoDB Atlas Search For Wati’s customers, the ability to search through conversation histories and company documents to retrieve valuable information is a key function. This often requires searching through millions of records to rapidly find answers so that they can respond to customers in real-time. By using MongoDB Atlas Search , Wati improved its search capabilities, ultimately helping its business customers perform more advanced analytics and improve their customer service agents’ efficiency and customer reporting. “[MongoDB] Atlas Search is really helpful because we don’t have to do a lot of technical integration, and minimal programming is required,” said Yeung. Looking ahead: Using AI and integrating more channels Wati expects to continue collaborating with MongoDB to add more features to its platform and keep innovating at speed. The company is currently exploring to build more AI capabilities of Wati KnowBot , as well as how it can expand its integration with other conversation platforms and channels such as Instagram and Facebook.

Hanabi Technologies Uses MongoDB to Power AI Assistant, Hana
For all the hype surrounding generative AI, cynics tend to view the few real-world implementations as little more than “fancy chatbots.” But for Abhinav Aggarwal, CEO of Hanabi Technologies , the idea of a generative AI-powered bot that is more than just an assistant was intriguing. “I’d been using ChatGPT since it launched,” said Aggarwal. “That got me thinking: How could we make a chatbot that was like a team member?” And with that concept, Hana was born. The problem with bots “Most generative AI chatbots do not act like people; they wait for a command and give a response,” said Aggarwal. “We wanted to create a human-like chatbot that would proactively help people based on what they wanted—automating reminders, for example, or fetching time zones from your calendar to correctly schedule meetings.” Hanabi’s flagship product, Hana, is an AI assistant designed to enhance team collaboration within Google Chat, working in concert with Google Workspace and its suite of products. “Our target customers are smaller companies of between 10 and 50 people. At this size you’re not going to build your own agent from scratch,” he said. Hana integrates with Google APIs to deliver a human-like assistant that chimes in with helpful interventions, such as automatically setting reminders and making sure meetings are booked in the right time zone for each participant. “Hana is designed to bring AI to smaller companies and help them collaborate in a space where they are already working—Google Workspace,” Aggarwal explained. The MongoDB Atlas solution For Hana to act like a member of the team, Hanabi needed to process massive amounts of data to support advanced features like retrieval-augmented generation (RAG) for better information retrieval across Google Docs and many other sources. And with a rapidly growing user base of over 600 organizations and 17,000+ installs, Hanabi also required a secure, scalable, and high-performing data storage solution. MongoDB Atlas provided a flexible document model, built-in vector database, and scalable cloud-based infrastructure, freeing Hanabi engineers to build new features for Hana rather than focusing on rote tasks like data extract, transform, and load processes or manual scaling and provisioning. Now, MongoDB Atlas handles a variety of responsibilities: Scalability and security: MongoDB Atlas’s auto-scaling and automatic backup features have enabled Hanabi to seamlessly grow its user base without the need for manual database management. RAG: MongoDB Atlas plays a critical role in Hana’s RAG functionality. The platform enables Hanabi to split Google Docs into small sections, create embeddings, and store these sections in Atlas’s vector database. Development Processes: According to Aggarwal, MongoDB’s flexibility in managing changing schemas has been essential to the company’s fast-paced development cycle. Data Visualization: Using MongoDB Atlas Charts has enabled Hanabi to create comprehensive dashboards for real-time data visualization. This has helped the team track usage, set reminders, and optimize performance without needing to build a manual dashboard. Impact and results With MongoDB Atlas, Hanabi can successfully scale Hana to meet the demands of its rapidly expanding user base. The integration is also enabling Hana to offer powerful features like automatic interactions with customers, advanced information retrieval from Google Docs, and manually added memory snippets, making it an essential tool for teams around the world. Next steps Hanabi plans to continue integrating more tools into Hana while expanding its reach to personal Gmail users. The company is also rolling out a new automatic-interaction feature, further enhancing Hana’s ability to proactively assist users without direct commands. MongoDB Atlas remains a key component of Hanabi’s stack, alongside Google Kubernetes Engine, NestJS, and LangChain, enabling Hanabi to focus on innovating to improve the customer experience.

Staff Engineering at MongoDB: Your Path to Making Broad Impact
Andrew Whitaker is a Senior Staff Engineer at MongoDB. His previous experience spans tiny startups to enormous organizations like AWS, where he held several different roles focusing on databases. Before joining MongoDB, he worked at a startup building optimized machine learning models in the cloud. Read on to learn more about why Andrew decided to join MongoDB in a senior-level engineering role and how his work is driving improvement within our engineering organization. Why MongoDB I have long been a fan of MongoDB’s products and services. MongoDB the database has always been a pleasure to work with – the system “brings joy” to quote a phrase. As a Python developer, I appreciate how the Python driver feels “Pythonic” in a completely natural way. The programmer interacts with the database using Python constructs: dictionaries, lists, and primitive types. By contrast, SQL databases force me to change my mental model, and the query language feels like an add-on that does not blend with the core language. As an engineer, I am always looking to expand my knowledge and grow my skills. The scope of challenges engineers face at MongoDB is what triggered my interest in the company. We obviously have people working on core databases and distributed systems. But, we also have teams dedicated to machine learning, streaming data, analytics, networking, developer tooling, drivers, and many more areas. It is very hard to get bored working at MongoDB. Finally, I would be remiss if I did not mention the people. Overall, MongoDB’s engineering culture prioritizes intelligence, low ego, and an ability to get stuff done. CL/CI (Continuous Learning, Continuous Improvement) Working at MongoDB has provided me with opportunities for continued learning and growth. Though I do not program as much as I did earlier in my career, I have recently been exploring the Rust language. I’m excited by Rust because it avoids the tradeoffs between predictable performance and safety. My work in the search space has given me exposure to the fast moving world of AI: vector embeddings, RAG, etc. For various reasons, I think MongoDB is uniquely positioned to do well in this area. On top of this, I’m working on some initiatives that are not fully public. I can say that one focus area is improving the sharding experience for our customers. We believe MongoDB sharding is best-in-breed. Still, the process requires more manual configuration than we think is ideal: customers select the shard key, cluster type, shard count, etc. We give guidance here, but I think we can raise the bar in terms of offering a seamless experience with less “futz”. I’m also working with the search team. We believe there is a natural affinity between MongoDB’s document model and AI/ML workloads. We have some features in the works that extend this integration in new and interesting ways. I also spend a fair bit of time driving quality improvements across our suite of products. Our CTO Jim Scharf frequently refers to our “ big 4 ” goals: security, durability, availability, and performance. These goals are more important than any feature we build. I’ve been working across the company to help teams define their availability SLO/SLAs. It turns out that measuring availability is a subtle topic. For example, a naive approach of counting the percentage of failed requests can underestimate downtime because customers make fewer requests when a service is unavailable. So, the first step is to clarify the definition of availability. Finally, as a lapsed academic (in a distant life, I was a graduate student at the University of Washington Department of Computer Science and Engineering), I’m always interested in finding ways to bridge theory and practice. I’ve been collaborating with some folks in our research team to drive improvements to our replication protocols. There are theoretical results that suggest it is impossible to simultaneously achieve low latency and strong consistency (“linearizability” in the technical jargon). However, we believe there are intermediate points in the consistency/latency spectrum that have not been fully explored. This work hasn't been made into a product yet, but stay tuned. Flexible working MongoDB is a hybrid company. Like many of our engineers, I work outside the company headquarters in New York City (I live in Seattle). I appreciate MongoDB’s approach to hybrid working and that company leadership, starting with Dev , cares about the well-being of their employees. It seems there are companies that don’t seem to trust their employees to make decisions, such as which days to come into the office, so I’m thankful for the autonomy I receive at MongoDB to work in a way that’s best for me. Remote work has its challenges, but I would say that the benefit for my work/life balance has been transformative. Final thoughts I have found MongoDB engineers demonstrate a strong mix of technical depth, pragmatism, and empathy. I have yet to find the “smart jerk” prototype that seems to exist throughout the tech industry. Overall, I have found MongoDB is open to change and growth at both the team level and the individual level. There is a willingness to evolve and improve that aligns with the company’s values and leadership principles and enables the success of our technology and people.

3 Ways MongoDB EA Azure Arc Certification Serves Customers
One reason more than 50,000 customers across industries choose MongoDB is the freedom to run anywhere—across major cloud providers, on-premises in data centers, and in hybrid deployments. This is why MongoDB is always working to meet customers where they are. For example, many customers choose MongoDB Atlas (which is available in more than 115 cloud regions across major cloud providers) for a fully managed experience. Other customers choose MongoDB Enterprise Advanced (EA) to self-manage their database deployments to meet specific on-premises or hybrid requirements. To that end, we’re pleased to announce that MongoDB EA is one of the first certified Microsoft Azure Arc-enabled Kubernetes applications, which provides customers even more choice of where and how they run MongoDB. Customer adoption of Azure Arc has grown by leaps and bounds. This new certification, and the launch of MongoDB EA as an Arc-enabled Kubernetes application on Azure Marketplace , means that more customers will be able to leverage the unparalleled security, availability, durability, and performance of MongoDB across environments with the centralized management of their Kubernetes deployments. We are very excited to have MongoDB available for our customers on the Azure Marketplace. By extending Azure Arc’s management capabilities to your MongoDB deployments, customers gain the benefit of centralized governance, enhanced security, and deeper insights into database performance. Azure Arc makes hybrid database management with MongoDB efficient and consistent. Collaboration between MongoDB and Microsoft represents an opportunity for many of our customers to further accelerate their digital transformation when building enterprise-class solutions with Azure Arc. Christa St Pierre, Partner Group Manager, Azure Edge Devices, Microsoft Here are three ways the launch of MongoDB EA on Azure Marketplace for Arc-enabled Kubernetes applications gives customers greater flexibility. 1. MongoDB EA supports multi-Kubernetes cluster deployments, simplifies management MongoDB Enterprise Advanced seamlessly integrates market-leading MongoDB capabilities along with robust enterprise support and tools for self-managed deployments at any scale. This powerful solution includes advanced automation, comprehensive auditing, strong authentication, reliable backup, and insightful monitoring capabilities, all of which work together to ensure security compliance and operational efficiency for organizations of any size. The relationship between MongoDB and Kubernetes is one of strong synergy. With Kubernetes, MongoDB EA really can run anywhere, such as a single deployment spanning on-premises and more than one public cloud Kubernetes cluster. Customers can use the MongoDB Enterprise Kubernetes Operator, a key component of MongoDB Enterprise Advanced, to simplify the management and automation of self-managed MongoDB deployments in Kubernetes. This includes tasks like creating and updating deployments, managing backups, and integrating with various Kubernetes services. The ability of the MongoDB Enterprise Kubernetes Operator to deploy and manage MongoDB deployments that span multiple Kubernetes clusters significantly enhances resilience, improves disaster recovery, and minimizes latency by allowing data to be co-located closer to where it is needed, ensuring optimal performance and reliability. 2. Azure Arc complements MongoDB EA, providing centralized management While MongoDB Enterprise Advanced is already among a select group of databases capable of operating across multiple Kubernetes clusters , it is now also supported in Azure Arc-enabled Kubernetes environments. Azure Arc enables the standardized management of Kubernetes clusters across various environments—including in Azure, on-premises, and even other clouds—while harnessing the power of Azure services. Azure Arc accomplishes this by extending the Azure control plane to standardize security and governance across a wide range of resources and locations. For instance, organizations can centrally monitor all of the Azure Arc-enabled Kubernetes clusters using Azure Monitor for containers , or they can enforce threat protection at scale using Microsoft Defender for Kubernetes. This centralized control significantly reduces the complexity of managing Kubernetes clusters running anywhere, as customers can oversee all resources and apply consistent security and compliance policies across their hybrid environment. 3. Customers can leverage the resilience of MongoDB EA and the centralized governance of Azure Arc Together, these solutions empower organizations to build robust applications across a wide array of environments, whether on-premises or in multi-cloud settings. The combination of MongoDB Enterprise Advanced and the MongoDB Enterprise Operator simplifies the deployment of MongoDB across Kubernetes clusters, allowing organizations to fully leverage enhanced resilience and geographic distribution that surpasses the capabilities of a single Kubernetes cluster. Azure Arc further enhances this synergy by providing centralized management for all of these Kubernetes clusters, regardless of where they are running; for customers running entirely in the public cloud, we recommend using MongoDB’s fully managed developer data platform, MongoDB Atlas. If you’re interested in learning more, we invite you to explore the Azure Marketplace listing for MongoDB Enterprise Advanced for Arc-enabled Kubernetes applications. Please note that aside from use for evaluation and development purposes, this offering requires the purchase of a MongoDB Enterprise Advanced subscription.
