Haisheng Yuan created CALCITE-3756: -------------------------------------- Summary: RelSubset should not match operand(RelNode.class) Key: CALCITE-3756 URL: https://issues.apache.org/jira/browse/CALCITE-3756 Project: Calcite Issue Type: Bug Components: core Reporter: Haisheng Yuan
Even RelSubset is a subclass of RelNode, but they are quite different. RelNode already fires these rules, it is not necessary to fire fore RelSubset. More importantly, it never worked due to CALCITE-3755. In addition, it will waste time to try to iterate class operands of RelSubset and try to match pattern operand(RelNode), given that it never matches when ascending. -- This message was sent by Atlassian Jira (v8.3.4#803005)
