------------------------------
Summary: Add a Cache for per-disk DB handles.
Key: HDDS-6540
URL: https://issues.apache.org/jira/browse/HDDS-6540
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Mark Gui
Assignee: Mark Gui
A new Cache for per-disk db handles after rocksdb-merge.
Originally we have the ContainerCache for per-container db handles.
And we should have a new DatanodeStoreCache for per-disk db handles which
should be relatively small.
We could choose whether to use the DatanodeStoreCache or the ContainerCache
according to the schema version in BlockUtils.getDB().
