[jira] [Created] (KAFKA-6571) KafkaProducer.close(0) should be non-blocking

Dong Lin created KAFKA-6571:
-------------------------------

             Summary: KafkaProducer.close(0) should be non-blocking
                 Key: KAFKA-6571
                 URL: https://issues.apache.org/jira/browse/KAFKA-6571
             Project: Kafka
          Issue Type: Bug
            Reporter: Dong Lin
            Assignee: Dong Lin


According to the Java doc of producer.close(long timeout, TimeUnit timeUnit), it is said that "Specifying a timeout of zero means do not wait for pending send requests to complete". However, producer.close(0) can currently block on waiting for the sender thread to exit, which in turn can block on user's callback.

We probably should not let producer.close(0) join the sender thread if user has specified zero timeout.
