-----------------------------------

             Summary: Move all non-batch specific classes in flink-java to flink-core
                 Key: FLINK-3303
                 URL: https://issues.apache.org/jira/browse/FLINK-3303
             Project: Flink
          Issue Type: Improvement
          Components: Core, Java API
    Affects Versions: 0.10.0
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.0.0


Currently, {{flink-java}} has a lot of classes that are also needed by the streaming api and that are useful to the classes in {{flink-core}}.
In particular, certain improvements to the state API are blocked by the fact that certain classes are not in {{flink-core}}.

I suggest to move classes from {{flink-java}} to {{flink-core}} after the following pattern:
  - {{flink-core}} will contain all classes that are common across the batch and streaming API.
  - {{flink-java}} will contain all batch API specific classes (we may eventually even think about renaming it to {{flink-batch-java}}.


Because {{flink-java}} references {{flink-core}}, this will not be a breaking change.
