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 . -- This message was sent by Atlassian Jira (v8.3.4#803005)
