Sergey Shelukhin commented on HIVE-19820:
-----------------------------------------
Truncate support and test that combines truncate for table and partition,
analyze, drop partition, etc.
I think if HiveQA keeps being slow I will just commit this and fix tests later.
I will try adding support for more exotic cases like rename partition and
rename column for now.
> add ACID stats support to background stats updater and fix bunch of edge
> cases found in SU tests

> 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.
