Soumyakanti Das commented on HIVE-27102:
----------------------------------------
Adding a link to a google doc that highlights common plan changes that we see
in Hive with Calcite 1.33.
It also lists q.out files which has large plan changes, and needs to be
reviewed more carefully.
> Upgrade Calcite to 1.33.0 and Avatica to 1.23.0

> New versions for Calcite and Avatica are available so we should upgrade to
> them.
> I had some WIP in HIVE-26610 for upgrading calcite to 1.32.0 but given that
> the work was not in very advanced state it is preferred to jump directly to
> 1.33.0.
> Avatica must be inline with Calcite so both need to be updated at the same
> time.
