---------------------------------
Summary: Clear up StateBackend, AbstractStateBackend abstractions
Key: FLINK-3360
URL: https://issues.apache.org/jira/browse/FLINK-3360
Project: Flink
Issue Type: Improvement
Components: Streaming
Reporter: Gyula Fora
Priority: Minor
Currently there is a StateBackend interface and an AbstractStateBackend class
which are not very closely related to each other. I think this should be
cleared up before the 1.0 release a little bit.
The KvState for instance requires an AbstractStateBackend which does not
implement the StateBackend. On the other hand the StateDescriptors bind to
StateBackends
I think we could get rid of the StateBackend interface and rename the
AbstractStateBackend -> StateBackend. We only need to modify the bind method of
the descriptors.
