> Currently producer.send() may block on metadata for up to max.block.ms. This behavior is well documented but it is a bit sub-optimal. Since we return a future we should be able to make producer.send() completely non-blocking. One idea is to simply insert the record into a global queue shared across all partitions, and let the sender thread fetch record from this queue and send to broker.
