Change subject: Limit number of rowsets in compaction selection to 32 in TSAN mode ...................................................................... Patch Set 1: The 256K is coming from the fact that the iterators are holding onto a BlockDecoder for each column, and the default cfile page size is 256K. So, those BlockDecoders that work by decompressing a page at a time up front are likely to retain ~256K of memory each. -- To view, visit http://gerrit.cloudera.org:8080/11885 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I01ad4ba3a13995c194c3308d72c1eb9b611ef766 Gerrit-Change-Number: 11885 Gerrit-PatchSet: 1 Gerrit-Owner: Will Berkeley <[email protected]> Gerrit-Reviewer: Adar Dembo <[email protected]> Gerrit-Reviewer: Alexey Serbin <[email protected]> Gerrit-Reviewer: Andrew Wong <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Todd Lipcon <[email protected]> Gerrit-Reviewer: Will Berkeley <[email protected]> Gerrit-Comment-Date: Tue, 13 Nov 2018 18:49:22 +0000 Gerrit-HasComments: No
