Hi Pieter, Does PUB-SUB do retransmissions at the TCP level ? We do not need retransmissions as that will impact the real time nature of our application. Even though pub-sub is unreliable overall, I am wondering if retransmissions happen to make sure a message is reliably delivered. Having a flag that says "no retransmissions" will also be helpful.
