Description

This issue is related to https://issues.apache.org/jira/browse/HBASE-23066.
In Date tiered compaction once we move to old window - we should ideally not cache the resultant file because generally those files are not read (as it is not the window of our interest). We can provide a switch to either turn it ON or OFF. Preferrably for Data tiered compaction this switch should be OFF.
