[jira] [Commented] (FLINK-15103) Performance regression on 3.12.2019 in various benchmarks

["Chesnay Schepler (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-15103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16989704#comment-16989704 ] 

Chesnay Schepler commented on FLINK-15103:
------------------------------------------

{{git log 8403fd4..60b3f2f}} doesn't print anything for me, shouldn't it be {{c41e087..60b3f2f}}?
8403fd4 is the latest benchmark, 60b3f2f is the benchmark right after the regression, c41e087 is the benchmark right before the regression.
