Summary: VolcanoPlanner#fireRules and VolcanoRuleCall#matchRecurse should ignore known-to-be-unimportant relations Key: CALCITE-2589 URL: https://issues.apache.org/jira/browse/CALCITE-2589 Project: Calcite Issue Type: Improvement Components: core Affects Versions: 1.17.0 Reporter: Vladimir Sitnikov Assignee: Julian Hyde {{call.getPlanner().setImportance}} is used to avoid use of known-to-be-inefficient relation, however the check of importance is performed very late. The check is performed in org.apache.calcite.plan.volcano.RuleQueue#skipMatch when ruleCalls have already been created. I suggest to move the check into VolcanoPlanner#fireRules and VolcanoRuleCall#matchRecurse It would reduce amount of "possible" rule executions. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
