Change subject: IMPALA-7219. 7.5% of Catalog Server heap wasted by empty HashMaps and ArrayLists ...................................................................... Patch Set 2: Right, it seems like this is just a case of wastage by IncompleteTable objects, which contain the entirety of the 'Table' superclass but in fact use none of it. We could probably get away with a much cheaper implementation of IncompleteTable that has only the "name" field and nothing else. -- To view, visit http://gerrit.cloudera.org:8080/10982 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: If9c75f65ecb3ba3f2c739fa483a84dc052f471c6 Gerrit-Change-Number: 10982 Gerrit-PatchSet: 2 Gerrit-Owner: Misha Dmitriev <count...@gmail.com> Gerrit-Reviewer: Misha Dmitriev <count...@gmail.com> Gerrit-Reviewer: Todd Lipcon <t...@apache.org> Gerrit-Reviewer: Vuk Ercegovac <vercego...@cloudera.com> Gerrit-Comment-Date: Fri, 20 Jul 2018 19:01:13 +0000 Gerrit-HasComments: No
