I have a service A that every once in a while needs to send a message to a cluster of services B1, B2 ... BN. Then all of these services need to receive that message reliably, and send a confirmation back to A. After A receives the confirmation from all services from cluster B, it needs to send a message to another cluster of services C1, C2 ... CN.
What is the right ZeroMQ pattern for this, and what sockets should I pick?
It seems like a ROUTER-DEALER situation where A is a ROUTER and Bs and Cs are DEALER-s. I need the transmission of these messages to have delivery guarantee so not sure if I can do PUB-SUB here.
