Change subject: IMPALA-6034: Add CPU and scanned bytes limits per query ...................................................................... Patch Set 11: I was talking to Pooja offline and realised that the CPU limit implementation is deeply flawed because we don't update the CPU usage at any regular cadence - e.g. scanner threads only update it when they exit. I'm thinking about making cpu_limit_s a "DEVELOPMENT" query option and leaving it undocumented until we can address that issue. The bytes read implementation works as expected. -- To view, visit http://gerrit.cloudera.org:8080/10415 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I4c6015e21da684bb9f33e236d71309dd4c178a20 Gerrit-Change-Number: 10415 Gerrit-PatchSet: 11 Gerrit-Owner: Mostafa Mokhtar <mmokh...@cloudera.com> Gerrit-Reviewer: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Mostafa Mokhtar <mmokh...@cloudera.com> Gerrit-Reviewer: Sailesh Mukil <sail...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Comment-Date: Wed, 18 Jul 2018 21:00:20 +0000 Gerrit-HasComments: No
