Change subject: IMPALA-7310: Partial fix for NDV cardinality with NULLs. ...................................................................... Patch Set 8: (1 comment) I think I'm probably OK with either approach. http://gerrit.cloudera.org:8080/#/c/16349/8/testdata/workloads/functional-query/queries/QueryTest/compute-stats-date.test File testdata/workloads/functional-query/queries/QueryTest/compute-stats-date.test: http://gerrit.cloudera.org:8080/#/c/16349/8/testdata/workloads/functional-query/queries/QueryTest/compute-stats-date.test@32 PS8, Line 32: 'd','DATE',1,22,4,4,-1,-1 Is this change right? I thought the column stats themselves were not meant to include nulls. It seems like it will be confusing if these show stats commands don't show the stored stats. -- To view, visit http://gerrit.cloudera.org:8080/16349 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iec967053b4991f8c67cde62adf003cbd3f429032 Gerrit-Change-Number: 16349 Gerrit-PatchSet: 8 Gerrit-Owner: Shant Hovsepian <[email protected]> Gerrit-Reviewer: Aman Sinha <[email protected]> Gerrit-Reviewer: David Rorke <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Qifan Chen <[email protected]> Gerrit-Reviewer: Shant Hovsepian <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Comment-Date: Fri, 28 Aug 2020 19:13:33 +0000 Gerrit-HasComments: Yes
