    The changes look good, we just have to figure out what to do about the methods on `StreamExecutionEnvironment`.
One thing I'd like to get rid of is `CheckpointableInputFormat.getCurrentState` returns a
Tuple that contains the split. The split is never used internally, it's only stored to return
it from this method but the read operator itself also stores the split so I think it is redundant.
