-----------------------------------
Hi [~pnowojski], I'm working on this. I agree with you that only checking
sources finished is not enough, but would it be simpler to just check all sink
operators are finished?

> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Checkpointing
> Reporter: Yun Gao
> Priority: Major
>
> Currently for bounded job in streaming mode, by default it will wait for one
> more checkpoint to commit the last piece of data. If the checkpoint period is
> long, the waiting time might also be long. to optimize this situation, we
> could eagerly trigger a checkpoint after all sources are finished.
