   > What is the plan for synchronization within the SnapshotChain structures? 
Snapshot diff could try to read at anytime, right?
   
   One `SnapshotChainManager` is initialized from the `SnapshotInfo`, loaded 
into memory and maintained by the `SnapshotMetadataManager` (or equivalent).  
On each `ratis `snapshot action, create and delete, the `SnapshotChain` is 
updated and current.  The state of snapshots is reflected by the 
`SnapshotChainManager` in this manner.  Each `SnapshotChain` user, including 
snapshot diff, find the `SnapshotChain `containing the current state of 
snapshots.  
   
   Further, on OM restart, the `SnapshotChainManager `is loaded into memory 
initialized with the persistent storage snapshot state stored in the OM 
snapshotInfo table.
