      Description

      Currently, we have a 'CachedStore' layer on top of the KeyValueStore implementation that we use. This might lead to double caching:
      i) Once at the CachedStore layer
      ii) Possibly cached again in the specific K-V store that we use (for eg: RocksDB / BDB)

      We need the CachedStore layer so that the writes to LoggedStore (if configured) are done in an efficient manner.

      We can then potentially do some config tuning for the K-V store to reduce its memory footprint and simply write to disk.
