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...

You own the account, wrote the application, and would be the one fixing it if something broke. So role-based access control (RBAC) can sound like an answer to a problem you do not have: managing other people. You do not need RBAC for your app to function; account keys still work while key-based authentication is enabled. But for a live Azure Cos...

This tutorial shows how common Elasticsearch search requests can be expressed using Azure Cosmos DB query patterns. Some Elasticsearch capabilities map directly to Cosmos DB full-text search functions, while others require separate queries or application-layer handling. Each step shows the closest Cosmos DB pattern and explains what changes in the ...

This article was authored by Justin Liu, co-founder and chief architect, Genspark. The work does not end when the prompt does A user comes to Genspark with a goal: research a market, build a presentation, produce a report, analyze a dataset, or complete another complex assignment. Our agents take it from there, working across tools, sources, and ...

You can now open Azure Cosmos DB Shell directly from Data Explorer in the Azure portal. The shell gives you a terminal-style way to work with Azure Cosmos DB. You can move through databases and containers as you would through folders, run NoSQL queries, inspect resources, and update data. When you launch it from Data Explorer, it is already conn...

This post focuses on one of the most important design tasks when migrating from Elasticsearch to Azure Cosmos DB: translating an Elasticsearch mapping into Azure Cosmos DB container configuration.  In Elasticsearch, a mapping defines how document fields are stored and indexed. Azure Cosmos DB is schema-agnostic, so there is no single mapping doc...
