[jira] [Created] (HIVE-18979) Enable AggregateReduceFunctionsRule from Calcite

Jesus Camacho Rodriguez created HIVE-18979:
----------------------------------------------

             Summary: Enable AggregateReduceFunctionsRule from Calcite
                 Key: HIVE-18979
                 URL: https://issues.apache.org/jira/browse/HIVE-18979
             Project: Hive
          Issue Type: Task
          Components: CBO
    Affects Versions: 3.0.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


The rule rewrites aggregate functions into simpler ones. It should help us gathering more common sub-expressions for a given plan, and it should have a positive effect on materialized view rewriting coverage too.
