Subject [jira] [Commented] (HIVE-19820) add ACID stats support to background stats updater
Date Wed, 04 Jul 2018 01:15:00 GMT


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

> 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.
