-------------------------------------
Summary: Generalize/unify state meta info
Key: FLINK-9799
URL: https://issues.apache.org/jira/browse/FLINK-9799
Project: Flink
Issue Type: Sub-task
Components: State Backends, Checkpointing
Affects Versions: 1.5.0
Reporter: Stefan Richter
Assignee: Stefan Richter
Flink currently has a couple of classes that describe the meta data of state
(e.g. for keyed state, operator state, broadcast state, ...) and they typically
come with their own serialization proxy and backwards compatibility story.
However, the differences between those meta data classes are very small, like
different option flags and a different set of serializers. Before introducing
yet another meta data for timers, we should unify them in a general state meta
data class.
