Change subject: IMPALA-6679,IMPALA-6678: reduce scan reservation ...................................................................... Patch Set 10: (1 comment) http://gerrit.cloudera.org:8080/#/c/9757/10//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/9757/10//COMMIT_MSG@42 PS10, Line 42: Observability: Is there something simple to be said about having stats vs. not having stats? How big can the difference be? It is always better to have stats? Suppose we have a worst-case scenario where having stats significantly regresses the throughput of a scan-heavy workload. How can that be addressed without dropping stats? Dropping stats should never be an acceptable workaround. -- To view, visit http://gerrit.cloudera.org:8080/9757 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ifc80e05118a9eef72cac8e2308418122e3ee0842 Gerrit-Change-Number: 9757 Gerrit-PatchSet: 10 Gerrit-Owner: Tim Armstrong <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: Bikramjeet Vig <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Comment-Date: Wed, 25 Apr 2018 23:37:23 +0000 Gerrit-HasComments: Yes
