Sergey Shelukhin commented on HIVE-19820:
-----------------------------------------
[~steveyeom2017] fyi the API change from this patch is going to be undone, it's
not needed for stats updater after switching to single write ID. So it
shouldn't conflict with CachedStore patch
> add ACID stats support to background stats updater

> 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.
