> Priority: Major
> Labels: pull-request-available
>
> 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.
