Yuan Mei commented on FLINK-4511: --------------------------------- There is a re-architect related to savepoint and checkpoint. Do not think periodic savepoint can benefit too much if it is purely user-owned (triggered) And do not know why periodic checkpoint is not enough. > Schedule periodic savepoints > ---------------------------- > > Key: FLINK-4511 > URL: https://issues.apache.org/jira/browse/FLINK-4511 > Project: Flink > Issue Type: New Feature > Components: Runtime / State Backends > Reporter: Ufuk Celebi > Priority: Minor > Labels: auto-deprioritized-major, stale-minor > > Allow triggering of periodic savepoints, which are kept in a bounded queue > (like completed checkpoints currently, but separate). > If there is no periodic checkpointing enabled, only periodic savepoints > should be schedulded. > If periodic checkpointing is enabled, the periodic savepoints should not be > scheduled independently, but instead the checkpoint scheduler should trigger > a savepoint instead. This will ensure that no unexpected interference between > checkpoints and savepoints happens. For this, I would restrict the savepoint > interval to be a multiple of the checkpointing interval (if enabled). -- This message was sent by Atlassian Jira (v8.20.1#820001)
