Change subject: IMPALA-7293: Show tuple layout in explain plan. ...................................................................... Patch Set 4: Code-Review+1 (4 comments) I have a few more suggestions for the layout, feel free to ignore them if you disagree or do not want to spend more time with this. http://gerrit.cloudera.org:8080/#/c/13193/4/testdata/workloads/functional-planner/queries/PlannerTest/tuple-layout.test File testdata/workloads/functional-planner/queries/PlannerTest/tuple-layout.test: http://gerrit.cloudera.org:8080/#/c/13193/4/testdata/workloads/functional-planner/queries/PlannerTest/tuple-layout.test@28 PS4, Line 28: missing stats The missing stats lead to different explain output, which will cause failed tests during the Jenkins build. http://gerrit.cloudera.org:8080/#/c/13193/4/testdata/workloads/functional-planner/queries/PlannerTest/tuple-layout.test@219 PS4, Line 219: Slot format=<offset nullable type relative-path> Maybe write this only once before the first tuple? http://gerrit.cloudera.org:8080/#/c/13193/4/testdata/workloads/functional-planner/queries/PlannerTest/tuple-layout.test@220 PS4, Line 220: 0 1 I would prefer a smaller padding to make the lines more compact. I wouldn't care about very large offsets, e.g. above 9999 - as the offsets are ordered, so most row will naturally aligned even without padding. http://gerrit.cloudera.org:8080/#/c/13193/4/testdata/workloads/functional-planner/queries/PlannerTest/tuple-layout.test@221 PS4, Line 221: ARRAY<ARRAY<INT>> array_array_col An idea to complicate the layout further: we could make the scalar case more compact + print the whole complex types by creating a new column like "complex-type" after the path. It would be empty for scalars, and the 3rd column for collections could be simply COLLECTION. -- To view, visit http://gerrit.cloudera.org:8080/13193 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iac38290217a219e75400e4206835992a7ea31dba Gerrit-Change-Number: 13193 Gerrit-PatchSet: 4 Gerrit-Owner: Abhishek Rawat <ara...@cloudera.com> Gerrit-Reviewer: Abhishek Rawat <ara...@cloudera.com> Gerrit-Reviewer: Csaba Ringhofer <csringho...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Reviewer: Todd Lipcon <t...@apache.org> Gerrit-Comment-Date: Wed, 08 May 2019 09:33:58 +0000 Gerrit-HasComments: Yes
