----------------------------------------------
> 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
> Priority: Major
>
> 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.
