Ben Stopford commented on KAFKA-4522:
-------------------------------------
It'd be good to have some empirical evidence that this was indeed a bottleneck
in the wider flow.
> Using Disruptor instead of Array Blocking queue in Kafka Producer

> Key: KAFKA-4522
> URL: https://issues.apache.org/jira/browse/KAFKA-4522
> Project: Kafka
> Issue Type: Improvement
> Components: producer
> Reporter: Pratik kumar
>
> Kafka Producer currently uses Java's Array Blocking Queue to store outbound
> kafka message before batching them in async mode. In case of high production
> rate of kafka messages,this adds to lock contention on the user and is
> generally hidden from user.(quoting from personal experience)
> Usage of LMAX Disruptor can reduce the lock contention overhead put by Kafka
> Producer
> LMAX Disruptor -> https://github.com/LMAX-Exchange/disruptor
> Also can someone help me understand if blocking queue gives any guarantees
> inherent to kafka's design(and hence is irreplaceable)
