Spring Data Azure Cosmos DB v3 for Core (SQL) API: Release notes and resources

APPLIES TO: SQL API

The Spring Data Azure Cosmos DB version 3 for Core (SQL) allows developers to use Azure Cosmos DB in Spring applications. Spring Data Azure Cosmos DB exposes the Spring Data interface for manipulating databases and collections, working with documents, and issuing queries. Both Sync and Async (Reactive) APIs are supported in the same Maven artifact.

Spring Data Azure Cosmos DB has a dependency on the Spring Data framework. The Azure Cosmos DB SDK team releases Maven artifacts for Spring Data versions 2.2 and 2.3.

The Spring Framework is a programming and configuration model that streamlines Java application development. Spring streamlines the "plumbing" of applications by using dependency injection. Many developers like Spring because it makes building and testing applications more straightforward. Spring Boot extends this handling of the plumbing with an eye toward web application and microservices development. Spring Data is a programming model and framework for accessing datastores like Azure Cosmos DB from the context of a Spring or Spring Boot application.

You can use Spring Data Azure Cosmos DB in your Azure Spring Cloud applications.

FAQ

How will I be notified of the retiring SDK?

Microsoft will provide 12 month's advance notice before the end of support of the retiring SDK to facilitate a smooth transition to a supported SDK. We'll notify you through various communication channels: the Azure portal, Azure updates, and direct communication to assigned service administrators.

Can I author applications by using a to-be-retired Azure Cosmos DB SDK during the 12-month period?

Yes, you'll be able to author, deploy, and modify applications by using the to-be-retired Azure Cosmos DB SDK during the 12-month notice period. We recommend that you migrate to a newer supported version of the Azure Cosmos DB SDK during the 12-month notice period, as appropriate.

After the retirement date, what happens to applications that use the unsupported Azure Cosmos DB SDK?

After the retirement date, Azure Cosmos DB will no longer make bug fixes, add new features, or provide support to the retired SDK versions. If you prefer not to upgrade, requests sent from the retired versions of the SDK will continue to be served by the Azure Cosmos DB service.

Which SDK versions will have the latest features and updates?

New features and updates will be added only to the latest minor version of the latest supported major SDK version. We recommend that you always use the latest version to take advantage of new features, performance improvements, and bug fixes. If you're using an old, non-retired version of the SDK, your requests to Azure Cosmos DB will still function, but you won't have access to any new capabilities.

What should I do if I can't update my application before a cutoff date?

We recommend that you upgrade to the latest SDK as early as possible. After an SDK is tagged for retirement, you'll have 12 months to update your application. If you're not able to update by the retirement date, requests sent from the retired versions of the SDK will continue to be served by Azure Cosmos DB, so your running applications will continue to function. But Azure Cosmos DB will no longer make bug fixes, add new features, or provide support to the retired SDK versions.
