Change subject: IMPALA-8092: Add an admission controller debug page ...................................................................... Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/12244/1/be/src/scheduling/admission-controller.h File be/src/scheduling/admission-controller.h: http://gerrit.cloudera.org:8080/#/c/12244/1/be/src/scheduling/admission-controller.h@449 PS1, Line 449: std::vector<int64_t> peak_mem_histogram_; > Quick initial question, can't remember if we discussed this offline - why n just looked at HdrHistogram, it seems like a full blown implementation of a histogram, not sure it its an overkill for our use case. I just went with fixed bucket for easy lookup of appropriate bucket and to avoid keeping track of the bucket-to-value mapping. Definitely a lot of ways we can do this and something more clever to allow variable range and buckets. open to suggestions. -- To view, visit http://gerrit.cloudera.org:8080/12244 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iff055d9709ea1bcc2f492adcde92241b6149f766 Gerrit-Change-Number: 12244 Gerrit-PatchSet: 1 Gerrit-Owner: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Pooja Nilangekar <pooja.nilange...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Comment-Date: Wed, 23 Jan 2019 19:53:43 +0000 Gerrit-HasComments: Yes
