> In FLIP-20, we need IterativeCondition to support an {{open()}} method to compile the generated code once. We do not want to insert a if condition  in the {{filter()}} method. So I suggest make IterativeCondition support {{RichFunction}} interface.
> Things to be very careful about:
> * backwards compatibility (we previously serialized conditions) - changes to those interfaces have to be done carefully
> * we want to be able to add dynamic patterns in the future, so at some point we have to open also on control message arrival
