Attila Doroszlai resolved HDDS-6238.
------------------------------------
Fix Version/s: 1.3.0
Resolution: Fixed
bq. If the pending keys to be flushed grows and includes a lot of deletes, list
operations can grow the memory quite a bit by caching deleted keys. The cache
for deleted keys can be skipped entirely.
> OM performance: Improve memory management of deleted object tracking during
> listing.

> During listing of keys the deleted keys are skipped. The current mechanism
> leads to bloat in memory, specially when there are multiple concurrent
