--------------------------------------
Hi [~becket_qin],
I find the fix for this issue has been merged into the master branch, but not
yet into the release-1.11 branch. Anything blocks it from being merged to 1.11?
> Add close() method and onCheckpointComplete() to the Source.

> Right now there are some caveats to the new Source API. From the
> implementation of some connectors. We would like to make the following
> improvements to the current Source API.
> # Add the following method to the {{SplitReader}} API.
> {{public void close() throws Exception；}}
> This method allows the SplitReader implementations to be closed properly when
> the split fetcher exits.
> # Add the following method to the {{SourceReader}} API.
> {{public void checkpointComplete(long checkpointId);}}
> This method allows the {{SourceReader}} to take some cleanup / reporting
> actions when a checkpoint has been successfully taken.
