Summary: Refactor State to Prepare For Key-Group State Backends Key: FLINK-4381 URL: https://issues.apache.org/jira/browse/FLINK-4381 Project: Flink Issue Type: Sub-task Components: Streaming Reporter: Aljoscha Krettek In order to use the new {{KeyGroupAssigner}}/{{key group sharding}} the state backends need no be able to deal with key groups. For this, we first need to refactor the state abstractions. Specifically, this touches how key-grouped state should be stored and also how state is sent to the {{CheckpointCoordinator}} and how it is stored. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
