-------------------------------------
Summary: High packet rate between brokers in kafka cluster.
Key: KAFKA-1563
URL: https://issues.apache.org/jira/browse/KAFKA-1563
Project: Kafka
Issue Type: Bug
Affects Versions: 0.8.1.1
Reporter: Fedor Korotkiy
On our kafka cluster with 3 brokers and input 40MB/s we see about 100K
packets/s traffic between brokers(not including consumers). Majority of packets
have small size(about 20bytes of data).
I have found that kafka server sets TcpNoDelay option on all sockets.
https://github.com/apache/kafka/blob/0.8.1/core/src/main/scala/kafka/network/SocketServer.scala#L202
And I think that causes the issue.
Can you please explain current behavior and fix it/make it configurable?
