Sorry, I don't really get it. Before I get the number of the records from the likes stream - I have to materialize that stream in order to get the result.
So far I can think of a custom *GraphStage* that will take 2 inputs - the profile and the stream, and produce one output - profile, that will be emitted only after the last element of the likes stream is consumed, hence the number of the records is known. -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
