Luke Hutchison commented on FLINK-6035:
---------------------------------------
I see, makes sense. I was going through my program and naming everything, and
noticed that groupBy seemed to be one of the only things that couldn't be
named. I didn't realize those were fused in the graph display of the pipeline.
Actually, one other thing I noticed was that collect() can't be named too, due
to the return type. It's probably not a time-consuming operation, since it
creates a complete instantiation of a DataSet in RAM, but maybe support a
{code}.collect(String name){code} method? (I could open a separate bug for
that, or rename this one, if you agree -- otherwise, feel free to close this
bug.)
