Summary: Reclaimable Rename entry filter for reclaiming renaming
entries
Key: HDDS-12561
URL: https://issues.apache.org/jira/browse/HDDS-12561
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Swaminathan Balachandran
Assignee: Swaminathan Balachandran
Currently rename entries are never reclaimed and these entries can be reclaimed
on snapshot deep cleaning by just peeking into the previous snapshot if the
object exists either in the directoryTable/FileTable/KeyTable. While performing
this operation we should ensure read locks are taken on the previous snapshot
and the previous snapshot is not deleted. As part of this patch we implement
ReclaimableRenameEntryFilter which extends abstract class ReclaimableFilter and
check whether this rename entry corresponding to the object exists in the
previous snapshot.
