Introducing vector database capabilities in Azure Cosmos DB for NoSQL (Public Preview)
 We are excited to announce that native vector indexing and search in Azure Cosmos DB for NoSQL is now available in preview! Azure Cosmos DB is the world’s first full-featured serverless database with vector search and features multiple vector index options from flat (exact), quantized flat, and a new DiskANN-based index. DiskANN is a suite of highly scalable, accurate, and cost-effective approximate nearest neighbor (ANN) algorithms, developed at Microsoft Research, for low-latency and cost-effective vector search at any scale. You can take advantage of Azure Cosmos DB's rich features such as a NoSQ...
Cross-region replication in vCore-based Azure Cosmos DB for MongoDB
A modern managed database service such as Azure Cosmos DB for MongoDB has a growing list of requirements in today’s world. Prompt recovery of the database availability when its region becomes unavailable is one of such critical functions. When a region is experiencing outage, there’re two primary methods for restoring access to data of a managed database located in that region – cross-region replication and backup. By default, vCore-based Azure Cosmos DB for MongoDB stores all cluster data in a selected Azure region. Today you can start using the new cross-region replication capability that allows you to m...
General Availability: Computed Properties in Azure Cosmos DB for NoSQL
We’re thrilled to share that Computed Properties have now hit General Availability in Azure Cosmos DB for NoSQL! Computed properties are a Cosmos DB developer’s dream come true! They allow you to write your query logic just once and then reuse it across multiple queries, saving you time and effort in your database operations. Computed Properties can be added to your indexing policy opening up the possibility to reduce the RU costs and latency of your queries! What are Computed properties Computed properties are a feature in Azure Cosmos DB that allow you to derive values from existing item properties. Howev...

Simplifying your Azure Cosmos DB migration: From Serverless to Provisioned throughput (preview)
Azure Cosmos DB offers a range of options to fit the diverse needs of cloud applications, including the choice between serverless and provisioned throughput accounts. The serverless option is ideal for workloads with unpredictable patterns, but there are instances when transitioning to a provisioned throughput account is advantageous for enhanced performance and more efficient cost management. We are delighted to introduce a new feature that allows for the seamless transition of an Azure Cosmos DB account from serverless to provisioned throughput. This feature aims at streamlining the migration process for our...
General Availability: Index Metrics in Azure Cosmos DB for NoSQL
You can now use the Azure Cosmos DB index metrics to optimize query performance with Index Advisor! Indexing metrics show two important pieces of information: Enabling indexing metrics: You can enable indexing metrics for a query by setting the PopulateIndexMetrics property to true. When not specified, PopulateIndexMetrics defaults to false. The indexing metrics are supported in the .NET SDK (version 3.21.0 or later) and Java SDK (version 4.19.0 or later), and the Python SDK (version 4.6.0 or later) Index impact score: The index impact score is the likelihood that an indexed path, based on t...
