Right, everything has to go through the leader. If the producer waits for ack=committed, it will get an exception when sending m3. So the producer is aware of that m3 may not be committed by the broker. The producer can choose to resend m3 if it wants to be sure that m3 is safely stored at the brok

Excellent thanks! BTW, in the slides, it shows the the message 'm3' is lost. I guess the leader is the single point of failure then when a producer sends a message, meaning it can never bypass the leader and write to the followers in case of leader failure right? On Thu, Feb 28, 2013 at 8:35 AM
