------------------------------------
Summary: PartialTableCache optimize for cleanup
Key: HDDS-11403
URL: https://issues.apache.org/jira/browse/HDDS-11403
Project: Apache Ozone
Issue Type: Improvement
Reporter: Sumit Agrawal
Assignee: Sumit Agrawal
With reference to HDDS-11201, where FullTableCache clean optimization is done,
similar mechanism is required for PartialTableCache.
As OMStatemachine and DoubleBuffer maintains order of transaction applied over
DB,
* check for all transaction (epoch) is not required to be verified
* And When higher epoch is received, this indicate all previous epoch cache
can be cleaned up.
Also in overload situation, and thread scheduling is slow, it can cause build
of worker queue as in FullTableCache. The situation is less as there is no
locking in this case.
So as optimization, similar approach can be followed.
