---------------------------------
Summary: Datanode delete operations should not impact rocksDB cache
Key: HDDS-4372
URL: https://issues.apache.org/jira/browse/HDDS-4372
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Components: Ozone Datanode
Reporter: Lokesh Jain
Currently datanode accesses container rockDB while processing delete
transactions received from SCM and when deleting service deletes the blocks.
During these accesses delete operations can end up evicting RocksDB cache
instances used for read/write. It is better to avoid evicting the cache entries.
It also needs to be made sure that there is only one rocksDB instance for a
particular container at any time.
