Jesus Camacho Rodriguez commented on HIVE-14496:
------------------------------------------------
[~ashutoshc], let's try to check this one in. I have addressed the most
important comments in the last patch. In particular:
- Loading all materialized views definitions for all users when HS2 starts
(instead of per session).
- Adding just an additional field for rewrite enabled (instead of creating a
'view descriptor'). This simplified a lot the changes in the scripts to upgrade
metastore.
I left for a follow-up:
- Extension of rules to match new patterns.
> Enable Calcite rewriting with materialized views

> Calcite already supports query rewriting using materialized views. We will
> use it to support this feature in Hive.
> In order to do that, we need to register the existing materialized views with
> Calcite view service and enable the materialized views rewriting rules.
> We should include a HiveConf flag to completely disable query rewriting using
> materialized views if necessary.
