In 0.7, each producer reconnects to the broker periodically. Messages sent
in different socket connections could arrive out of order. Take a look at
reconnect.interval in http://kafka.apache.org/07/configuration.html
. If you
don't use VIP for the producers, you can actually set reconnect.interval to
a really large value. In 0.8, there is no reconnect.interval any more.
Messages sent from a single producer are expected to arrive in order at the
broker, as long as they sent to the same partition in a topic.
