> 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.
