Hi Edward,

What is the current version you are using? Starting in 0.8.1 the default
partitioner of the producer would no longer be round-robin at a per-message
level but would stick to one partition for a period (the metadata refresh
period, which is 10 min by default) and then round-robin to another
partition in the next period.
