Sergey Shelukhin commented on HIVE-19820:
-----------------------------------------
Backup for the patch; not done yet. The problem now without txn list is that
stats cannot be written without write ID, yet that is what analyze does. So in
the paradigm where we treat stats as data for ACID, we'd need to allocate write
ID for analyze. cc [~ekoifman]

> Follow-up from HIVE-19418.
> Right now it checks whether stats are valid in an old-fashioned way... and
> also gets ACID state, and discards it without using.
> When ACID stats are implemented, ACID state needs to be used to do
> version-aware valid stats checks.
