> 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.
