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.
