Amazon Managed Service for Apache Flink introduces enhanced snapshots
Amazon Managed Service for Apache Flink now supports enhanced snapshots, a capability that lets you capture, export, and restore application state across Apache Flink applications and Amazon Cloud Regions, so you can run blue/green deployments, easily migrate self-managed workloads to Amazon Managed Service for Apache Flink without losing state, and keep state in a secondary region for cross-region recovery.
To deploy an application update without pausing processing for blue/green deployments, create an enhanced snapshot from an application and use it to start a second application. To migrate a self-managed workload, import its Apache Flink savepoint from an Amazon Simple Storage Service (Amazon S3) bucket into Amazon Managed Service for Apache Flink as an enhanced snapshot. For cross-region recovery, export an enhanced snapshot to an Amazon S3 bucket, and replicate the exported state to a bucket in a secondary region.
Enhanced snapshots are now available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD. To learn more, check out the Amazon Managed Flink overview page and developer guide.
