> Whenever compaction happens, the cleaner immediately deletes older obsolete
> files. In certain cases it would be beneficial to retain these for certain
> period. For example : if you are serving the file metadata from cache and
> don't want to invalidate the cache during compaction because of performance
> reasons.
> For this purpose we should introduce a configuration
> hive.compactor.delayed.cleanup.enabled, which if enabled will delay the
> cleaning up obsolete files. There should be a separate configuration
> CLEANER_RETENTION_TIME to specify the duration till which we should retain
> these older obsolete files.
> It might be beneficial to have one more configuration to decide whether to
> retain files involved in an aborted transaction
> hive.compactor.aborted.txn.delayed.cleanup.enabled .
