Azure Cosmos DB Java SDK for SQL API: Release notes and resources
APPLIES TO: SQL API
This is the original Azure Cosmos DB Sync Java SDK v2 for SQL API which supports synchronous operations.
This is not the latest Java SDK for Azure Cosmos DB! Consider using Azure Cosmos DB Java SDK v4 for your project. To upgrade, follow the instructions in the Migrate to Azure Cosmos DB Java SDK v4 guide and the Reactor vs RxJava guide.
On February 29, 2024 the Azure Cosmos DB Sync Java SDK v2.x will be retired; the SDK and all applications using the SDK will continue to function; Azure Cosmos DB will simply cease to provide further maintenance and support for this SDK. We recommend following the instructions above to migrate to Azure Cosmos DB Java SDK v4.

Release and retirement dates
Microsoft will provide notification at least 12 months in advance of retiring an SDK in order to smooth the transition to a newer/supported version. New features and functionality and optimizations are only added to the current SDK, as such it is recommend that you always upgrade to the latest SDK version as early as possible.
After 30 May 2020, Azure Cosmos DB will no longer make bug fixes, add new features, and provide support to versions 1.x of the Azure Cosmos DB Java SDK for SQL API. If you prefer not to upgrade, requests sent from version 1.x of the SDK will continue to be served by the Azure Cosmos DB service.
After 29 February 2016, Azure Cosmos DB will no longer make bug fixes, add new features, and provide support to versions 0.x of the Azure Cosmos DB Java SDK for SQL API. If you prefer not to upgrade, requests sent from version 0.x of the SDK will continue to be served by the Azure Cosmos DB service.

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.
If you have a support plan and require technical support, contact us by filing a support ticket.
