----------------------------------------------
Summary: Skip Druid/JDBC rules in optimizer when there are no
Druid/JDBC sources
Key: HIVE-19300
URL: https://issues.apache.org/jira/browse/HIVE-19300
Project: Hive
Issue Type: Improvement
Components: CBO, Druid integration, JDBC
Affects Versions: 3.0.0, 3.1.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
When there are no Druid/JDBC sources in a plan, we can skip the complete blocks
that trigger rules to push computation to Druid/JDBC, since they will have no
effect on the plan, and thus avoid the overhead of traversing the plan to try
to find matchings.
