---------------------------------

             Summary: improve java-producer-consumer-demo
                 Key: KAFKA-14755
                 URL: https://issues.apache.org/jira/browse/KAFKA-14755
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Luke Chen


while running both the examples, I saw flood of logs output because we print one line for message sent, and one line for message received. In java-producer-consumer-demo, there will be 10000 records sent/received, so > 20000 lines of logs output. Same for exactly-once-demo. Maybe we should consider to reduce the record number.

 

One more thing, in exactly-once-demo.java, there are clear class java doc in the demo file, but there's nothing in java-producer-consumer-demo.java. We should also improve that.

 

Lastly, the main thread in java-producer-consumer-demo won't exit if timed out waiting for demo producer and consumer to finish. You'll see exception thrown, but the application keeps waiting there.
