------------------------------------
Summary: worker queue of FullTableCache cleanup consume much memory
Key: HDDS-11201
URL: https://issues.apache.org/jira/browse/HDDS-11201
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Manager
Reporter: Sumit Agrawal

As observed, FullTableCache cleanup queue consumes 4GB as events keeps getting
added to queue (reached 28442228 for this case) for cleanup of evictionEntries.
There is a possibility of this due to lock used in cleanup thread, and this
lock is non-fair.

As part of this, need check if evictionEntries can be optimized as used for
cache eviction when cache value is null and epoch is current value transaction
Id. and/or fair locking mechanism.
