Because Azure Cosmos DB Java SDK v4 has up to 20% enhanced throughput, TCP-based direct mode, bug fixes, and provide support for the latest backend features, we’ll retire 3.x version of the Azure Cosmos DB Java SDK for SQL API on 31 August 2024. We recommend you make the switch early to gain the enhanced benefits of Azure Cosmos DB Java SDK 4.x. Start using SDK 4.x for net-new subscriptions/accounts. If you have a question, please post it in this thread.
