BTW, noticed that the jira number is wrong. FLINK-19689 was for a different issue. I like Stephan's points above. - `Checkpointable` seems unnecessary considering almost all sources need some checkpointing in streaming mode. - reusing `CheckpointListener` for `onCheckpointComplete(checkpointId)` seems like a reasonable option. - `snapshotState(checkpointId)` is better than two broken-up methods of `snapshotState()` and `onCheckpoint(checkpointId)`, because either way checkpointId is leaked to source implementation. I don't see much problem with leaking checkpointId, because we are not talking about end users of Kafka source. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
