Robert Metzger commented on FLINK-2419: --------------------------------------- Okay, I suspect its this one: https://github.com/apache/flink/pull/937 I'll still re-open the issue until we have a test that ensures that the {{notifyCheckpointComplete}} is called exactly once. > DataStream sinks lose key information > ------------------------------------- > > Key: FLINK-2419 > URL: https://issues.apache.org/jira/browse/FLINK-2419 > Project: Flink > Issue Type: Bug > Components: Streaming > Reporter: Gyula Fora > Assignee: Gyula Fora > Priority: Blocker > Fix For: 0.10 > > > If the user applies an addSink method after keyBy, the sink will not have the > information of the key as the transform method is bypassed. > This makes it impossible to use partitioned states with sinks. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
