> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.2.0
> Reporter: Aljoscha Krettek
> Assignee: Stefan Richter
> Priority: Blocker

> The recent introduction of key-grouped state breaks queryable state because the JobManager does not yet forward the client to the correct TaskManager based on key-group ranges.
> This will either have to be implemented on the JobManager side, i.e. in {{AkkaKvStateLocationLookupService}} or on the {{TaskManager}} when state is registered. The JobManager can know the mapping because it should know the {{parallelism}}/{{maxParallelism}} which it can use to determine where the state for a key-group is stored. The {{TaskManager}} send a {{NotifyKvStateRegistered}} message that already contains a {{keyGroupIndex}} field that is not useful/correct at the moment, though.
