Hi, I tried to have a thought and comparison on possible long-term options:

> URL: https://issues.apache.org/jira/browse/FLINK-21080
> Project: Flink
> Issue Type: Sub-task
> Components: API / DataStream, Runtime / Checkpointing
> Reporter: Yun Gao
> Assignee: Yun Gao
> Priority: Major
> Labels: auto-unassigned
>
> Most legacy source operators would record the offset for each partitions, and
> after recovery it would read from the recorded offset. If before a checkpoint
> some subtasks are finished, the corresponding partition offsets would be
> deserted in the checkpoint. Then if the job recover with this checkpoint, the
> legacy source would re-discovery all the partitions and for those finished
> tasks, the legacy source would re-read them since their offsets are not
> recorded.
> Therefore, we would like to fail the checkpoint if some legacy source
> operators have part of subtasks finished.
