Description

This Jira is to fix listParts 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 listParts of a MPU key, it should use both in-memory cache and rocksdb mpu table to list parts of a mpu key.

 

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.
