[jira] [Created] (FLINK-4556) Make Queryable State Key-Group Aware
Aljoscha Krettek created FLINK-4556:
---------------------------------------
Summary: Make Queryable State Key-Group Aware
Key: FLINK-4556
URL: https://issues.apache.org/jira/browse/FLINK-4556
Project: Flink
Issue Type: Improvement
Components: Streaming
Affects Versions: 1.2.0
Reporter: Aljoscha Krettek
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.
