Summary: Support TERMINATE/SUSPEND Job with Checkpoint
Key: FLINK-12619
URL: https://issues.apache.org/jira/browse/FLINK-12619
Project: Flink
Issue Type: New Feature
Components: Runtime / State Backends
Reporter: Congxian Qiu(klion26)
Assignee: Congxian Qiu(klion26)
Inspired by the idea of FLINK-11458, we propose to support terminate/suspend a
job with checkpoint. This improvement cooperates with incremental and external
checkpoint features, that if checkpoint is retained and this feature is
configured, we will trigger a checkpoint before the job stops. It could
accelarate job recovery a lot since:
1. No source rewinding required any more.
2. It's much faster than taking a savepoint since incremental checkpoint is
enabled.
Please note that conceptually savepoints is different from checkpoint in a
similar way that backups are different from recovery logs in traditional
database systems. So we suggest using this feature only for job recovery, while
stick with FLINK-11458 for the
upgrading/cross-cluster-job-migration/state-backend-switch cases.
