Ruben Q L commented on CALCITE-3447: ------------------------------------ Thanks [~daimin], could you please include the test in the PR? > Fix equivalents in method SubstitutionVisitor#go > ------------------------------------------------ > > Key: CALCITE-3447 > URL: https://issues.apache.org/jira/browse/CALCITE-3447 > Project: Calcite > Issue Type: Bug > Components: core > Reporter: daimin > Priority: Minor > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > Code segment here depends on `hashcode` and `equals` methods of class > `MutableRel`: > [https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/plan/SubstitutionVisitor.java#L492-L502] > > However the implementations of class `MutableScan` delegates to class > `TableScan`, which directly relies on implementations of class `Object`. This > leads to a situation that two `MutableScan` on the exactly same table will > not be considered as equivalent. -- This message was sent by Atlassian Jira (v8.3.4#803005)
