                 Key: FLINK-19035

             Project: Flink
          Issue Type: Sub-task
          Components: API / DataStream

We should also agree if we want to remove those in 1.x version already or do we want to wait for 2.0.

We should remove DataStream#fold and all related classes and methods such as FoldFunction, FoldingState, FoldingStateDescriptor ...
