I am new to nanomsg and I am looking to implement a client/server service using REQ/REP. Server is a stateless service, but depends on another google service for reply to incoming requests. REP Service should be either asynchronous, so that it can handle other REQ requests in the queue while data gets ready form google service, or it should start workers[ideally from pool] to process REQ request in the queue. But I have not found any examples that does anyone of the above or may be I am missed some docs. The example req/rep is targeted at synchronous REP implementations. I am looking for, how to start a worker / create a pool of workers at service start and assign worker to each incoming request. Or, with asynchronous REP how can I send the reply to the appropriate/correct client/REQ when data gets ready. I have seen a thread regarding SP RAW that can be used, but not sure how it helps in my case. I appreciate any help or guidance. Thanks R K.
