Description
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 |
