Denys Kuzmenko commented on HIVE-25189:
---------------------------------------
[~scarlin], [~kkasa] any ideas if that could be leveraged with HIVE-28238
(cache later when we have types) or could be reverted?
> Cache the validWriteIdList in query cache before fetching tables from HMS

> For a small performance boost at compile time, we should fetch the
> validWriteIdList before fetching the tables. HMS allows these to be batched
> together in one call. This will avoid the getTable API from being called
> twice, because the first time we call it, we pass in a null for
> validWriteIdList.
