   > We can have have large number of buckets in the system, but we can have smaller number of snapshots. In such a case, its easier to iterate over SnapshotInfo Table and just list the buckets from there.
   
   @prashantpogde I think that can be considered further optimization. The currently approach with `listSnapshot` on each bucket is not the most efficient. I agree with @hemantk-12 that we can make the bucket's snapshot existence check O(1) by building some reverse mapping in `OmSnapshotManager`. This might require some more digging. Maybe in another jira.
