Amazon DocumentDB Serverless

Amazon DocumentDB Serverless now provides up to 35% higher throughput with the launch of platform version 4. Platform versions represent improvements in performance, scaling capabilities, or features, and are automatically managed at the cluster level.

All new serverless clusters launch on the latest platform version available in your AWS Region. You can upgrade existing clusters on platform version 3 to platform version 4 by applying the serverless-platform-version-update pending maintenance action. This gives you control over when to apply the update, either immediately or during your next scheduled maintenance window. After you upgrade to a newer platform version, you can't downgrade to a previous version.

What to do

  • Upgrade existing clusters to platform version 4 using the serverless-platform-version-update action.
  • Monitor the platform version of your clusters in the AWS Management Console or through the DescribeDBClusters API.
