Immediat >From the compute incremental stats side, IMO, we need the following metrics, (1) Time spent, stats size from on-demand incremental stats fetch RPCs (planner) (2) Time spent to merge the stats after the child queries finish I think (2) is already captured in some form (and perhaps we can make it more clear by narrowing down the scope to just measure the time taken to merge). I was hoping this change makes it easy to do (1). I'm not sure what is needed from the expression nodes. May be I'm missing something. -- To view, visit http://gerrit.cloudera.org:8080/11388 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I808d55a225338912ebaebd0cf71c36db944b7276 Gerrit-Change-Number: 11388 Gerrit-PatchSet: 3 Gerrit-Owner: Todd Lipcon <t...@apache.org> Gerrit-Reviewer: Andrew Sherman <asher...@cloudera.com> Gerrit-Reviewer: Bharath Vissapragada <bhara...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Todd Lipcon <t...@apache.org> Gerrit-Reviewer: Vuk Ercegovac <vercego...@cloudera.com> Gerrit-Comment-Date: Fri, 07 Sep 2018 18:00:48 +0000 Gerrit-HasComments: Yes
