> Key: HUDI-1348
> URL: https://issues.apache.org/jira/browse/HUDI-1348
> Project: Apache Hudi
> Issue Type: Improvement
> Components: DeltaStreamer, Utilities
> Reporter: Vu Ho
> Priority: Major
> Labels: core-flow-ds, pull-request-available, user-support-issues
>
> Since DeltaStreamer makes heavily use of file listing, if the source contains
> a lot of tiny files, this could quickly become a bottle neck. We need a way
> to delete/archive files once processed by DeltaStreamer.
> It seems like the best way to reliably clean up the source is after DeltaSync
> commit the checkpoint successfully. We could add a new public method to
> Source e.g. `postCommit()` and invoke it after each successful commit
