Azure Cosmos DB SDK for Java provides a client library for interacting with Cosmos DB's NoSQL API. It supports both synchronous and asynchronous (reactive) programming models via `CosmosClient` and `CosmosAsyncClient`. Use it to manage databases, containers, and documents with global distribution and configurable consistency levels.
Using the SDK directly gives you typed responses, built-in retry policies, and reactive support that raw HTTP calls to the Cosmos REST API do not provide out of the box.
When to use it
- Querying documents across globally distributed containers with partition-aware requests
- Switching between strong and eventual consistency per operation based on read requirements
- Handling 429 rate-limit errors with built-in retry logic in high-throughput Java services
- Building reactive data pipelines using `CosmosAsyncClient` with Project Reactor
- Tracking Request Unit consumption per operation to optimize Cosmos DB provisioned throughput
