Summary: Allow One Input of ConnectedStream to be Broadcast (was: Allow
ConnectedStreams to Be Keyed on Only One Side)
> Allow One Input of ConnectedStream to be Broadcast

> Key: FLINK-3659
> URL: https://issues.apache.org/jira/browse/FLINK-3659
> Project: Flink
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 1.0.0
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
>
> Currently, we only allow partitioned state when both inputs are keyed (with
> the same key type). I think a valid use case is to have only one side keyed
> and have the other side broadcast to publish some updates that are relevant
> for all keys.
> When relaxing the requirement to have only one side keyed we must still
> ensure that the same key is used if both sides are keyed.
