Upon reading about stateful functions, it seems as though first, a data stream has to flow to an event ingress. Then, the stateful functions will perform computations via whatever functionality it provides. Finally, the results of said computations will flow to the event egress which will be yet another datastream within the data stream job.
Is my understanding correct? I was hoping that a stateful function could be called by a process function, is that possible? (I am guessing no). Please let me know. Thank you. Sincerely, Marco A. Villalobos
