> This Jira will be used to track changes for maintaining additional metadata to support Snapshot feature. This will include on-disk structure i.e. new RocksDB table(s) to track 
>  * all buckets that are snapshotted
>  * list of all the snapshots for such buckets 
> In-memory structure would maintain an LRU cache of snapshot-chains for snapshotted buckets as required.
> Also, Refer to CheckpointBasedDesign doc for details.
