Sending multiple multipart ZMQ PUB messages in parallel

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

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.
