[jira] [Created] (HIVE-14492) Optimize query in CREATE MATERIALIZED VIEW statement in Calcite

Jesus Camacho Rodriguez created HIVE-14492:
----------------------------------------------

             Summary: Optimize query in CREATE MATERIALIZED VIEW statement in Calcite
                 Key: HIVE-14492
                 URL: https://issues.apache.org/jira/browse/HIVE-14492
             Project: Hive
          Issue Type: Sub-task
          Components: Materialized views
    Affects Versions: 2.2.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


When we create a materialized view, the query specified in the statement should be optimized by Calcite, as this might make a huge performance difference when we materialize the results.

Further, Calcite optimization should be trigger too when we execute {{ALTER MATERIALIZED VIEW ... REBUILD}}, as the changes in the original tables might lead to a new optimized plan.
