Change subject: IMPALA-6116: Bound memory usage of DataStreamSevice's service queue ...................................................................... Patch Set 2: (1 comment) http://gerrit.cloudera.org:8080/#/c/9282/2/be/src/runtime/krpc-data-stream-mgr.cc File be/src/runtime/krpc-data-stream-mgr.cc: http://gerrit.cloudera.org:8080/#/c/9282/2/be/src/runtime/krpc-data-stream-mgr.cc@176 PS2, Line 176: service_mem_tracker_->Release(transfer_size); > There may be a temporary window in which the process mem limit is exceeded, The process limit is checked by looking at TC-malloc and the buffer pool, rather than adding up the children consumption. So, I don't think this impacts the process limit. Who are the parents of these two trackers? Tim, what's your take on the order that the Consume() and Release() should occur in? -- To view, visit http://gerrit.cloudera.org:8080/9282 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Idea4262dfb0e0aa8d58ff6ea6a8aaaa248e880b9 Gerrit-Change-Number: 9282 Gerrit-PatchSet: 2 Gerrit-Owner: Michael Ho <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Lars Volker <[email protected]> Gerrit-Reviewer: Michael Ho <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Comment-Date: Thu, 15 Feb 2018 00:06:27 +0000 Gerrit-HasComments: Yes
