Take the newly AI-focused DP-420 exam free at Microsoft Ignite—or take the certification exam today and save 50% through Data Days. OpenAI’s storage platform uses Azure Cosmos DB to help serve products used by more than one billion people each week. If you want to build AI applications at that kind of scale, the newly...

Your project started with one or two people. Now developers, operators, analysts, and applications all need access to Azure Cosmos DB. Giving everyone the same permissions might feel efficient, but it makes every identity more powerful than its job requires.  As your team grows, organize access around jobs, not people. Separate management access...

Give each coding task its own disposable database environment, then merge the reviewed changes - not the test database. When parallel coding agents share a database In From Local Development to CI Workflows with the Azure Cosmos DB Emulator, we used FleetCharge to make local development and CI repeatable. Start the emulator, seed known data, run ...

Explore local data from the terminal with Azure Cosmos DB Shell. Connect to the emulator, inspect FleetCharge documents, run queries, and point-read depot partitions.

Follow an AI application from a blank folder to a system built for production AI application development often starts with a promising prototype. A real application has to do more than produce an answer: it needs current operational data, the ability to take actions and complete transactions, memory that carries across sessions, coordination b...

When you change a database-backed feature, a successful HTTP response isn't enough. You need to know that the write reached storage, the application retrieved the updated record, and the next answer reflects it. The Azure Cosmos DB Emulator runs locally in Docker and lets us use the SDK we'll use in production. We'll develop against it first, th...

In our previous post, we introduced the private preview of Safe Key Rotation, a feature that helps Azure Cosmos DB customers avoid service disruptions during key rotations. By showing when each account key was last used, it helps teams make informed decisions before rotating keys or moving to Entra ID. This capability addresses a common chal...

Over a typical 2 day window, we record 10 times as many emulator sessions lasting more than 30 minutes for vNext as for the legacy emulator. Our bet is that agentic development is helping drive the difference! The appeal is straightforward: coding agents need a database they can run anywhere. They also need a database they can start, seed, test ag...

Co-authored with Praveen Raja P Azure Cosmos DB already includes a powerful event foundation: change feed provides a durable, ordered record of item changes within each logical partition. It is ideal for reacting to operational data as it changes, building projections, and driving workflows directly from the database. Confluent Cloud adds a ...

The first few minutes of a new AI project often feel productive. Create a chat endpoint, connect a model, send a prompt, and display the answer. Then the real questions arrive. Where should the agent store memory? How do we keep one customer's data away from another? How do we trace the source of an answer? What happens when an action require...
