      Description

      Folding is an operation that cannot be done incrementally in a distributed way and that also cannot be done on merging windows. Now that we have AggregatingState and aggregate operations we should deprecate folding in the APIs and deprecate FoldingState.

      I suggest to remove folding completely in Flink 2.0
