Subject [jira] [Commented] (HIVE-14496) Enable Calcite rewriting with materialized views
Date Thu, 15 Dec 2016 17:09:58 GMT


Ashutosh Chauhan commented on HIVE-14496:

In metastore/if/hive_metastore.thrift can you declare rewrite_enabled as optional and have
that declaration at last in the struct.
+1 with that change, pending QA run.

> 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.
