Fedor Korotkiy created KAFKA-1563: ------------------------------------- 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? -- This message was sent by Atlassian JIRA (v6.2#6252)
