2017 - Cosmos DB

It was a pretty amazing year for Azure Cosmos DB, highlighted by the launch of the service, the preview and general availability of Graph, Table APIs, MongoDB API, native Spark connector and many other awesome capabilities. There were breakthroughs in making our SLAs truly industry-leading, adding native integration with Azure Functions and launching Try Cosmos DB for free to empower anyone to experience and play with our service without having an Azure account or having to specify a credit card. Below is a look back at 2017 and some of the memorable milestones.

The Launch of Azure Cosmos DB

imageIn May, we were super excited to announce the general availability of Azure Cosmos DB – Microsoft’s globally distributed, massively scalable, multi-model database service. It is the first globally-distributed data service that lets you elastically scale throughput and store across any number of geographical regions while guaranteeing low latency, high availability and consistency. While also backed by the most comprehensive SLAs in the industry. It is the first cloud database to natively support a multitude of data models and popular query APIs. It is built on a novel database engine capable of ingesting sustained volumes of data and provides blazing fast queries. All this without having to deal with schema or index management. And it is the first cloud database to offer five well-defined consistency models so you can choose just the right one for your app. Read more about Azure Cosmos: The Industry’s first globally-distributed, multi-model database service and relive the launch by watching the #MSBuild Day 1 Keynote video.

Technical rigor behind Azure Cosmos DB

imageThe work of Dr. Leslie Lamport, Turing Award Winner and a world-renowned computer scientist has profoundly influenced many large-scale distributed systems. Azure Cosmos DB is no exception. Over the course of the seven years building Azure Cosmos DB, Leslie’s work has been a constant source of our inspiration and a solid foundation for our platform. Since its inception, Azure Cosmos DB has offered developers a choice between five well-defined consistency models along the consistency spectrum – strong, bounded staleness, session, consistent prefix, and eventual. You can configure the default consistency level on your Azure Cosmos DB account and later override the consistency on a specific read request. You can read all about the consistency levels in Azure Cosmos DB in the article Tunable data consistency levels in Azure Cosmos DB. To create these five consistency levels and build many of the capabilities within Azure Cosmos DB, we married decades-worth of distributed systems and database research with world-class engineering rigor. In this interview with Leslie shares his thoughts on the foundations of Azure Cosmos DB, his influence in the design of Azure Cosmos DB and in particular on the modelling of consistency choices.

Native Spark Connector for Azure Cosmos DB

imageIn June, we announced the preview of the native Spark connector for Azure Cosmos DB that provides seamless interaction with globally-distributed, multi-model data and empowers customers to easily run analytics, machine learning and data science on top of globally-distributed operational data. Spark connector for Azure Cosmos DB enables real-time data science, machine learning, advanced analytics and exploration over globally distributed data in Azure Cosmos DB by connecting it to Apache Spark. The connector efficiently exploits the native Azure Cosmos DB managed indexes and enables updateable columns when performing analytics.  It also utilizes push-down predicate filtering against fast-changing globally-distributed data addressing a diverse set of IoT, data science, and analytics scenarios. Our goal is to help developers write globally distributed apps more easily using the tools and APIs they are already familiar with. Azure Cosmos DB’s database engine natively supports SQL API, MongoDB API, Gremlin (graph) API, and Azure Table API. With the updated Spark connector for Azure Cosmos DB, Apache Spark can now interact with all Azure Cosmos DB data models: Documents, Tables, and Graphs. Read more about Spark Connector for #CosmosDB seamless interaction with globally-distributed, multi-model data and Azure #CosmosDB announcements.

Azure Cosmos DB Change Feed

Azure Cosmos DB is extremely well-suited for IoT, gaming, retail, and operational logging applications. imageA common design pattern in these applications is to use changes to the data to trigger additional actions. To help you build powerful applications on top of Azure Cosmos DB we built change feed support, which provides a sorted list of documents within a collection in the order in which they were modified. To address scalability while preserving simplicity of use, we introduced the Azure Cosmos DB Change Feed Processor Library. Read more to learn when and how you should use Change Feed Processor Library.

Azure Cosmos DB – database for serverless era image

We are now entering the era of serverless. With serverless architecture, there is a whole new range of applications emerging, in particular serverless event-driven apps. When the event is triggered your application pops into action, does what it needs to do and disappears again. That’s why we start calling it “severless” because in essence, your server does not exist until it is needed. In September, we announced the availability of native integration between Azure Cosmos DB and Azure Functions. With this native integration, you can create database triggers, input bindings, and output bindings directly from your Azure Cosmos DB account. Using Azure Functions and Azure Cosmos DB, you can create and deploy event-driven serverless apps with low-latency access to rich data for a global user base. Watch this demo on Serverless Apps with Azure Cosmos DB & Azure Functions at Microsoft Ignite.

With this extension you are now able to browse Cosmos DB resources across both SQL (DocumentDB) and MongoDB interfaces along-side existing experiences for Azure Blobs, tables, files, and queues in ASE.

Entry point for unlimited collections/containers is now 60% cheaperimage

Last February, we lowered entry point for unlimited containers making them 75% cheaper. We continue making improvements in our service and in December announced that unlimited containers have now an entry point that is 60% cheaper than before. Instead of provisioning 2,500 RU/sec as a minimum, you can now provision an unlimited collection at 1,000 RU/sec and scale in increments of 100 RU/sec. Unlimited containers (collections) enable you to dynamically scale your provisioning from as low as 1,000 RU/sec to millions of RU/sec with no limit on storage consumption.

Most of the above mentioned happened thanks to you - our customers, MVPs, developers, partners and organically, as we worked hard to add value to our customers and empower anyone to build globally-distributed applications with ease. It took us years to operationalize the capabilities we currently offer. We were fortunate to have Internet scale Microsoft applications to learn from which allowed us to identify, validate, and operationalize the five consistency models, the industry-leading comprehensive SLAs, the guaranteed single-digit millisecond latency for reads and writes and robust partition management for independent scaleout of storage and throughput. We have been constantly working on optimizing the propagation delays across various workloads by dynamic replication topologies, made our software stack across a variety of failure modes and interconnectivity issues for both within and across, various Azure regions. We have constantly optimized the core replication protocol (we are not done yet) to bring all of this to you, our customers. Azure Cosmos DB is the database of the future - it is what we believe is the next big thing in the world of massively scalable databases! It makes your data available close to where your users are, worldwide and makes building planet scale apps super-easy using the API and data model of your choice.

A new year is on the way and the possibilities are endless. We can’t wait to share what we have in store for you in 2018 and see what you will build with Azure Cosmos DB this upcoming year2018 - Cosmos DB

Happy New Year!
