Snapshot manager

It's a best practice for Flink Applications to regularly trigger savepoints/snapshots to allow for more seamless failure recovery. Snapshot manager automates this task and offers the following benefits:

  • takes a new snapshot of a running Kinesis Data Analytics for Apache Flink Application

  • gets a count of application snapshots

  • checks if the count is more than the required number of snapshots

  • deletes older snapshots that are older than the required number
