Summary: FilterProjectTransposeRule should allow filter conditions with correlated variables to be pushed down Key: CALCITE-2617 URL: https://issues.apache.org/jira/browse/CALCITE-2617 Project: Calcite Issue Type: Improvement Components: core Affects Versions: 1.17.0 Reporter: Stamatis Zampetakis Assignee: Julian Hyde Fix For: 1.18.0 The rule always forbids conditions with correlated variables to be pushed down (as of [CALCITE-769|https://issues.apache.org/jira/browse/CALCITE-769] to avoid certain problems in the decorrelation of the query). However, in the general context of query optimization, it is beneficial to push-down filters and the fact that there is a correlated variable is not a reason to skip this optimization. In order to avoid regressions, and at the same time enable correlated conditions to be pushed down we should make the pushing of correlated variables configurable. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
