Steve Yeom commented on HIVE-18693:
-----------------------------------
But from the perspective of Atomicity, in case of having orphan transaction
after client dies, we need a mechanism.
Keeping table/partition names in the Metastore is easiest given that file
system directory level metadata is limited
due to append only operations' being allowed. But recovery manager and metadata
cache might be an alternative.
> Snapshot Isolation does not work for Micromanaged table when a insert
> transaction is aborted
