Bharat Viswanadham updated HDDS-1985:
-------------------------------------
Description:
This Jira is to fix lisVolumes API in HA code path.
In HA, we have an in-memory cache, where we put the result to in-memory cache
and return the response, later it will be picked by double buffer thread and it
will flush to disk. So, now when do listVolumes, it should use both in-memory
cache and rocksdb volume table to list volumes for a user.
No fix is required for this, as the information is retrieved from the MPU Key
table, this information is not retrieved through RocksDB Table iteration. (As
when we use get() this checks from cache first, and then it checks table)
Used this Jira to add an integration test to verify the behavior.
