Change subject: KUDU-3002: prioritize WAL unanchoring when under memory pressure ...................................................................... Patch Set 3: > Patch Set 2: > > Forgot to mention: could you sanity check this on a real cluster? Tested on a real cluster with a 1% memory pressure limit and 1GiB hard limit, with a constant insert loadgen workload and manual upserts. https://imgur.com/MI4BG6Q I eventually saw DMS flushes a few seconds after upserting (i.e. the DMS flushes are not being triggered immediately, just when they become "old" enough to unanchor WALs). -- To view, visit http://gerrit.cloudera.org:8080/14910 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ibd85e8f2904a36b74cd6a3038c9ec49bb1ff9844 Gerrit-Change-Number: 14910 Gerrit-PatchSet: 3 Gerrit-Owner: Andrew Wong <[email protected]> Gerrit-Reviewer: Adar Dembo <[email protected]> Gerrit-Reviewer: Andrew Wong <[email protected]> Gerrit-Reviewer: Bankim Bhavsar <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Todd Lipcon <[email protected]> Gerrit-Comment-Date: Tue, 17 Dec 2019 08:58:44 +0000 Gerrit-HasComments: No
