Hi all! I just noticed that all Scala DataStream methods like "rebalance", "broadcast", "shuffle", etc are defined without parenthesis.
I am a bit puzzled about this. Even though these methods do not modify the DataStream object on which they are called, they define for example a distributed shuffle, which makes them not really side effect free. I would define them with parenthesis. If we decide to do this, and since this is API breaking, we should do it before 1.0 Greetings, Stephan PS: I suspect that this comes from the fact that IntelliJ has the annoying behavior to define all methods with empty parenthesis by default as no-parenthesis methods.
