Summary: Configuration option to exclude rule by a regex on their
description
Key: HIVE-25880
URL: https://issues.apache.org/jira/browse/HIVE-25880
Project: Hive
Issue Type: New Feature
Components: CBO
Affects Versions: 4.0.0
Reporter: Alessandro Solimando
Assignee: Alessandro Solimando
Introduce a configuration option to exclude rules via a regex on the rule
description, based on Calcite's
[org.apache.calcite.plan.AbstractRelOptPlanner#setRuleDescExclusionFilter|https://github.com/apache/calcite/blob/0065d7c179b98698f018f83b0af0845a6698fc54/core/src/main/java/org/apache/calcite/plan/AbstractRelOptPlanner.java#L186].
The motivation is to provide a quick workaround when one or more rules are
causing issues at planning time, without code changes.
Another use would be to quickly experiment on the impact of disabling one or
more rules on the compute plan.
