[jira] [Created] (KAFKA-6705) producer.send() should be non-blocking

Dong Lin created KAFKA-6705:
-------------------------------

             Summary: producer.send() should be non-blocking
                 Key: KAFKA-6705
                 URL: https://issues.apache.org/jira/browse/KAFKA-6705
             Project: Kafka
          Issue Type: Improvement
            Reporter: Dong Lin
            Assignee: Dong Lin


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.
