Hi, I have multiple clients PUSHing messages to a pair of PULL workers. Clients connect, workers bind. I'm trying to figure out how to properly gracefully restart a worker without loosing messages.
Reading the docs I know I should do a unbind() on the worker PULL socket, but I'm not sure how my application will get notified that all in-transit or already queued messages are delivered? Are PUSH sockets somehow notified that their peer is no longer available? Or must I use another socket (maybe a PUB/SUB) so that workers signal clients "hey, I'm going away" and ask them the disconnect()? Is there a way for workers to check after unbind if there are still connected clients? This would help workers determine when its safe to exit after a zmq_pool reveals no more messages pending. Finally, I know the Guide is not up-to-date to 3.2, is there a wiki or something with up-to-date 3.2 zeromq patterns?
