[jira] [Updated] (FLINK-12791) Introduce LocalKeyedStateHandle
interface and implement LocalKeyedKeyGroupsStateHandle /
LocalKeyedIncrementalKeyedStateHandle
[ https://issues.apache.org/jira/browse/FLINK-12791?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
vinoyang updated FLINK-12791:
-----------------------------
Description:
To deal with local keyed state, we need to implement a {{LocalKeyedStateHandle}} interface to distinguish the existed {{KeyedStateHandle}}. This is a marker interface does not provide anything further methods.
Based on {{LocalKeyedStateHandle}} we provided two implementations: {{LocalKeyedKeyGroupsStateHandle}} and {{LocalKeyedIncrementalKeyedStateHandle}}. They are specialized {{KeyGroupsStateHandle}} and {{IncrementalKeyedStateHandle for states that are local keyed.}}
> Introduce LocalKeyedStateHandle interface and implement LocalKeyedKeyGroupsStateHandle / LocalKeyedIncrementalKeyedStateHandle
