Dong Lin updated KAFKA-6705:
----------------------------
Description: 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. (was: Currently producer.send() may block on
metadata or full buffer 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.)
