Sending multiple multipart ZMQ PUB messages in parallel

Question

What is the preferred pattern for this? Multiple contexts? Waiting until all patterns for the message are assembled and sending them synchronized?

Answer 1

Found a solution:

• Each sender connects to an IPC PUSH socket and writes multipart messages to it. When it's done, it closes the socket.
• A dedicated thread receives on the opposite IPC PULL socket and writes the messages, part-by-part, into one TCP PUB socket.
