James,
There are separate queues for each partition, so there are no
guarantees on the order of the sends (or callbacks) between
partitions.
(Actually, IIRC, the code intentionally randomizes the partition order
a bit, possibly to avoid starvation)

Hi,
I'm trying to understand the new producer, and the order in which the Callbacks
will be called.
From my understanding, records are batched up per partition. So all records
destined for a specific partition will be sent in order, and that means that
their callbacks will be called in order.
