ASF GitHub Bot commented on FLINK-9809: --------------------------------------- Github user StephanEwen commented on the issue: https://github.com/apache/flink/pull/6309 Thanks, merging once CI is green... > Support setting CoLocation constraints on the DataStream Transformations > ------------------------------------------------------------------------ > > Key: FLINK-9809 > URL: https://issues.apache.org/jira/browse/FLINK-9809 > Project: Flink > Issue Type: Improvement > Components: Streaming > Reporter: Stephan Ewen > Assignee: Stephan Ewen > Priority: Major > Labels: pull-request-available > Fix For: 1.6.0 > > > Flink supports co location constraints for operator placement during > scheduling. This is used internally for iterations, for example, but is not > exposed to users. > I propose to add a way for expert users to set these constraints. As a first > step, I would add them to the {{StreamTransformation}}, which is not part of > the public user-facing classes, but a more internal class in the DataStream > API. That way we make this initially a hidden feature and can gradually > expose it more prominently when we agree that this would be a good idea. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
