-------------------------------------
Summary: Default queue.enqueue.timeout.ms to -1
Key: KAFKA-709
URL: https://issues.apache.org/jira/browse/KAFKA-709
Project: Kafka
Issue Type: Bug
Components: producer
Affects Versions: 0.8
Reporter: Chris Riccomini
Assignee: Jun Rao
Hey Guys,
It seems that, by default, producers in 0.8 are async, and have a default
queue.enqueue.timeout.ms of 0. This means that anyone who reads messages faster
than they're producing them will likely end up eventually hitting this
exception:
Exception in thread "Thread-3" kafka.common.QueueFullException: Event queue is
full of unsent messages, could not send event:
KeyedMessage(PageViewEventByGroupJson,Missing Page
Group,java.nio.HeapByteBuffer[pos=0 lim=125 cap=125])

at kafka.producer.Producer.send(Producer.scala:77)
As it says in https://cwiki.apache.org/KAFKA/kafka-mirroring.html, this can
result in losing messages, and nasty exceptions in the logs. I think the better
default is setting queue.enqueue.timeout.ms to -1, which will just block until
the queue frees up.
