Sravya Tirukkovalur commented on HIVE-14906:

Seems like if we do the following, we should be able to support an atomic 
getSnapshot() API:
- Set transaction level to "repeatable-read", so that all reads within a 
transaction would be from a single generation point. In other words, concurrent 
writes would not affect the state of the read.
- Make all the reads of snapshot building function part of the same transaction.

> HMS should support an API to get consistent atomic snapshot associated with a 
> Notification ID.
