Summary: Integrate Operator Coordinators with Checkpoints
Key: FLINK-16177
URL: https://issues.apache.org/jira/browse/FLINK-16177
Project: Flink
Issue Type: Sub-task
Components: Runtime / Checkpointing
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.11.0
The operator coordinators are stateful and hence need to store state in
checkpoints.
See FLIP-27 for details on operator coordinators:
https://cwiki.apache.org/confluence/display/FLINK/FLIP-27%3A+Refactor+Source+Interface
The initial implementation approach is to trigger coordinator checkpoints
first, and when all coordinator checkpoints are done, then the source
checkpoint barriers will be injected.
_Note:_ This functionality will eventually replace the checkpoint master hooks.
