Change subject: IMPALA-7942 (part 2): Add query hints for predicate selectivities ...................................................................... Patch Set 28: (1 comment) http://gerrit.cloudera.org:8080/#/c/18023/28/fe/src/main/java/org/apache/impala/analysis/Expr.java File fe/src/main/java/org/apache/impala/analysis/Expr.java: http://gerrit.cloudera.org:8080/#/c/18023/28/fe/src/main/java/org/apache/impala/analysis/Expr.java@1065 PS28, Line 1065: if (allowConjunctsFromChild(this)) { This still has not addressed the concern that getConjuncts() which is a generic method for collecting conjuncts and the behavior should not change based on a hint. Probably best to add a new function that returns only the local conjuncts and call that with the appropriate hint checking logic inline in the caller so the context and intent is all clear. -- To view, visit http://gerrit.cloudera.org:8080/18023 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I2776b9bbd878b8a21d9c866b400140a454f59e1b Gerrit-Change-Number: 18023 Gerrit-PatchSet: 28 Gerrit-Owner: wangsheng <[email protected]> Gerrit-Reviewer: Amogh Margoor <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Kurt Deschler <[email protected]> Gerrit-Reviewer: Qifan Chen <[email protected]> Gerrit-Reviewer: Quanlong Huang <[email protected]> Gerrit-Reviewer: Xiang Yang <[email protected]> Gerrit-Reviewer: Zoltan Borok-Nagy <[email protected]> Gerrit-Reviewer: wangsheng <[email protected]> Gerrit-Comment-Date: Wed, 05 Apr 2023 14:11:21 +0000 Gerrit-HasComments: Yes
