> Flink supports co location constraints for operator placement during scheduling. This
is used internally for iterations, for example, but is not exposed to users.
> I propose to add a way for expert users to set these constraints. As a first step, I
would add them to the {{StreamTransformation}}, which is not part of the public user-facing
classes, but a more internal class in the DataStream API. That way we make this initially
a hidden feature and can gradually expose it more prominently when we agree that this would
be a good idea.
