I looked into the performance regression around partitioned materialized views (i.e., `materialized_view_partitioned_2.q`) and from my point of view is not blocking for merging the PR. First of all, it appears the regression appears only in the context of MV rewrites so the impact is limited. Secondly, I assume that the performance/rewrite bug is already there even before the upgrade. If we modify the query to use `ref op literal` I guess the rewrite will fail to use the MV for the same reason. Finally, since we are not planning to make an immediate Hive release the performance regression will never reach end-users since it will be fixed by the time we deliver 4.3.0. For tracking purposes, please raise a JIRA ticket for this bug/regression and mark it as a blocker for the Hive 4.3.0 release adding the appropriate links with HIVE-29641 and potentially the next HIVE ticket tracking the upgrade to calcite 1.43.0. -- This is an automated message from the Apache Git Service.
