> Support checkpoint alignment with finished input channels
> ---------------------------------------------------------
>
> Key: FLINK-21086
> URL: https://issues.apache.org/jira/browse/FLINK-21086
> Project: Flink
> Issue Type: Sub-task
> Components: API / DataStream, Runtime / Checkpointing
> Reporter: Yun Gao
> Priority: Major
> Labels: pull-request-available
>
> For a non-source task, if one of its precedent task has finished, the
> precedent task would send EndOfPartition to it. Then for checkpoint after
> that, this task would not receive the barrier from the channel that has sent
> EndOfPartition. To finish the alignment, CheckpointBarrierHandler would
> insert barriers before EndOfPartition for these channels.
