Glen Geng commented on HDDS-4533:
---------------------------------
The rocksDB could be considered as a snapshot of SCM, as long as we add the
applyIndex into the DB.
The initialize job is actually loadSnapshot. After it is done,
StateMachineUpdater needs replaying entries between appyIndex + 1 and
lastLogIndex. Finally, the leader SCM can process incoming read/write request.

> {{PipelineStateManagerV2Impl}} adds the pipeline back to the pipeline table
> (RocksDB) during initialization which is unnecessary. This can be avoided.
