We are happy to announce that MongoDB v1.8.0 is now available. 1.8 is the stable follow-up release to 1.6, which came out in August of 2010. Version 1.8 introduces many new features, along with bug fixes and other improvements. Some of the highlights:
- Sharding performance improvements
- Replica set enhancements, including support for authentication
- Spherical geo search
- Covered and sparse indexes
- B-tree index self-compaction
- New map/reduce options for incremental updates
- Tab completion in the shell
A journaling storage engine has been one of the most requested and discussed features within the MongoDB community, and we’re happy to announce that journaling is now available. With journaling enabled, crash recovery is fast and safe.
There were no major changes to sharding, but this release includes many internal improvements, making for a vastly improved experience. As an example, splitting and balancing are considerably faster, with less impact on the overall system.

MongoDB European conferences next week
There’s just a week to go before our European conferences, when over 400 members of the MongoDB community will gather in London, Paris, and Berlin. The level of interest in and enthusiasm for MongoDB is really exciting. There are just a few places left if you still want to attend either the London and Berlin events. Paris is now sold out but we are taking names for the waiting list. 10gen founder Eliot Horowitz, and several of the key engineers developing the MongoDB project will be presenting sessions aimed at developers and administrators interested in learning how to use the database, with sessions on schema design, indexing, administration, deployment strategies, scaling, and other features. You will also get to hear from several companies about some of the ways in which they are using MongoDB. Here’s just a taste of some of those sessions planned: Graham Tackley of Guardian News and Media will talk about why the Guardian chose MongoDB for guardian.co.uk David Mytton, Founder, Boxed Ice, who use MongoDB to handle billions of database documents, will talk about monitoring MongoDB. Russell Smith, UKD1 Limited, will cover Geo & capped collections with MongoDB - use cases & performance in the real world. Martin Tepper, Travel IQ will explain the architectural problems, and how Travel IQ solved them by using MongoDB as a layer on top of their RDBMS. Lennart Koopmann, XING, will talk about how MongoDB capped collections are perfect for logging. Lennart built his project Graylog2 on top of a capped collection and will talk about his experiences, what you can do with them and what they are good at. Maxime Topolov will talk about how freerice.com, a Drupal site is using MongoDB to serve over 20 Millions page views per day. François de Metz & Ori Pekelman, AF83, will talk about how UCEngine, an Open Source Unified Communication and Collaboration application toolkit, is using MongoDB to store event data in an effecient way. Victor Goya, one of the core developer of UC Engine, will provide an overview of the architecture of UCEngine and a detailed feedback on how it benefits from MongoDB. The conferences are also a great opportunity to meet with and discuss your interest in or usage of MongoDB with the 10gen team and other MongoDB users. We are really looking forward to catching up with you next week, both during the conferences and and at the after parties! :-) MongoUK 2011, 21st March Mongo France 2011, 23rd March Mongo Germany 2011, 25th March Special thanks to Skills Matter in London and AF83 and La Cantine in Paris for their support and partnership for these events. Finally, there are some slots open for lightning talks in London and Berlin. Please contact firstname.lastname@example.org if you are interested in presenting. We look forward to seeing you next week!
Australian Start-Up Ynomia Is Building an IoT Platform to Transform the Construction Industry and its Hostile Environments
The trillion dollar construction industry has not yet experienced the same revolution in technology you might have expected. Low levels of R&D and difficult working environments have led to a lack of innovation and fundamental improvements have been slow. But one Australian start-up is changing that by building an Internet of Things (IoT) platform to harness construction and jobsite data in real time. “Productivity in construction is down there with hunting and fishing as one of the least productive industries per capita in the entire world. It's a space that's ripe for people to come in and really help,” explains Rob Postill , CTO at Ynomia. Ynomia has already been closely involved with many prestigious construction projects, including the residential N06 development in London’s famous 2012 Olympic Village. It was also integral to the construction of the Victoria University Tower in Australia. Link to Podcast Episode Here “These projects involve massive outflow of money: think about glass facades on modern buildings, which can represent 20-30 percent of the overall project cost. They are largely produced in China and can take 12 weeks to get here,” says Postill. “Meanwhile, the plasterer, the plumber, the electrician are all waiting for those glass facades to be put on so it is safe for them to work. If you get it wrong, you can go in the deep red very quickly.” To tackle these longstanding challenges, Ynomia aims to address the lack of connectivity, transparency and data management on construction sites, which has traditionally resulted in the inefficient use of critical personnel, equipment and materials; compressed timelines; and unpredictable cash flows. To optimize productivity, Ynomia offers a simple end-to-end technology solution that creates a Connected Jobsite. Helping teams manage materials, tools, and people across the worksite in real time. IOT in a Hostile Environment The deployment of technology in construction is often fraught with risk. As a result, construction sites are still largely run on paper, such as blueprints, diagrams and models as well as the more traditional invoices and filing. At the same time, there is a constant need to track progress and monitor massive volumes of information across the entire supply chain. Engineers, builders, electricians, plumbers, and all the other associated professionals need to know what they need to do, where they need to be, and when they need to start. “The environment is hostile to technology like GPS, computers, and mobile phone reception because you have a lot of Faraday cages and lots of water and dust,” explains Postill. “You can't have somebody wandering around a construction site with a laptop; it'll get trashed pretty quickly." Enter MongoDB Atlas “On a site, you might be talking about materials, then if you add to that plant & equipment, or bins, or tools etc, you're rapidly getting into thousands and thousands of tags, talking all the time, every day,” said Postill. That means thousands of tags now send millions of readings on Ynomia building sites around the world. All these IoT data packets must be stored efficiently and accurately so Ynomia can reassemble the history of what has happened and track tagged inventory, personnel, and vehicles around the site. Many of the tag events are also safety critical so accuracy is a vital component and packets can't be missed. To address these needs Ynomia was looking for a database that was scalable, flexible, resilient and could easily handle a wide variety of fast-changing sensor data captured from multiple devices. The final component Postill was looking for in a database layer was freedom: a database that didn't lock them into a single cloud platform as they were still in the early stages of assessing cloud partners. The Commonwealth Scientific and Industrial Research Organisation , which Postill had worked with in the past, suggested MongoDB , a general purpose, document-based database built for modern applications. “The most important factor was that the database is event-driven, which I knew would be difficult in the traditional relational model. We deal with millions of tag readings a day, which is a massive wall of data,” said Postill. A Cloud Database Ynomia is using MongoDB Atlas , the global cloud database service, now hosted on Microsoft Azure. Atlas offers best-in-class automation and proven practices that combine availability, scalability, and compliance with the most demanding data security and privacy standards. “When we started we didn't know enough about the problem and we didn't want to be constrained," explained Postill. "MongoDB Atlas gives us a cloud environment that moves with us. It allows us to understand what is happening and make changes to the architecture as we go." Postill says this combination of flexibility and management tooling also allows his developers to focus on business value not undifferentiated code. One example Postill gave was cluster administration: "Cluster administration for a start-up like us is wasted work," he said. "We’re not solving the customer's problem. We're not moving anything on. We’re focusing on the wrong thing. For us to be able to just make that problem go away is huge. Why wouldn’t you?" Atlas also gives Ynomia the option to spin out new clusters seamlessly anywhere in the world. This allows customers to keep data local to their construction site, improving latency and helping solve for regional data regulations. Real Time Analytics The company has also deployed MongoDB Charts, which takes this live data and automatically provides a real time view. Charts is the fastest and easiest way to visualize event data directly from MongoDB in order to act instantly and decisively based on the real-time insights generated by event-driven architecture. It allows Ynomia to share dashboards so all the right people can see what they need to and can collaborate accordingly. “Charts enables us to quickly visualize information without having to build more expensive tools, both internally and externally, to examine our data,” comments Postill. “As a startup, we go through this journey of: what are we doing and how are we doing it? There's a lot of stuff we are finding out along the way on how we slice and re-slice our data using Charts.” A Platform for Future Growth Ynomia is targeting a huge market and is set for ambitious growth in the coming years. How the platform, and its underlying architecture, can continue to scale and evolve will be crucial to enabling that business growth. “We do anything we can to keep things simple,” concluded Postill. “We pick technology partners that save us from spending time we shouldn't spend so we can solve real problems. We pick technologies that roll with the punches and that's MongoDB.” When we started we didn't know enough about the problem and we didn't want to be constrained," explained Postill. "MongoDB Atlas gives us a cloud environment that moves with us. It allows us to understand what is happening and make changes to the architecture as we go. Rob Postill, CTO, Ynomia
