Alessandro Solimando updated HIVE-25880:
----------------------------------------
Description:
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.
An example of configuration would be as follows:
{code:java}
set
hive.cbo.rule.exclusion.regex=HiveJoinPushTransitivePredicatesRule|HivePreFilteringRule;
{code}
The above configuration setting would exclude from planning both
_HiveJoinPushTransitivePredicatesRule_ and _HivePreFilteringRule_ rules.
