Kostas Kloudas reassigned FLINK-2646: ------------------------------------- Assignee: (was: Kostas Kloudas) > Rich functions should provide a method "closeAfterFailure()" > ------------------------------------------------------------ > > Key: FLINK-2646 > URL: https://issues.apache.org/jira/browse/FLINK-2646 > Project: Flink > Issue Type: Improvement > Components: Core > Affects Versions: 0.10.0 > Reporter: Stephan Ewen > Fix For: 1.0.0 > > > Right now, the {{close()}} method of rich functions is invoked in case of > proper completion, and in case of canceling in case of error (to allow for > cleanup). > In certain cases, the user function needs to know why it is closed, whether > the task completed in a regular fashion, or was canceled/failed. > I suggest to add a method {{closeAfterFailure()}} to the {{RichFunction}}. By > default, this method calls {{close()}}. The runtime is the changed to call > {{close()}} as part of the regular execution and {{closeAfterFailure()}} in > case of an irregular exit. > Because by default all cases call {{close()}} the change would not be API > breaking. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
