Review Comment:
It's the requirement on the HIVE-28755 Jira.
From my perspective, the purpose of this PR is to reduce the size of all the
column stats and to prevent the affect on performance. And the size of the
column stats might take quite long time to stack up. So 365 days might be an
appropriate time.
