Jun Rao commented on KAFKA-1282: -------------------------------- Nicu, I was doing some manual testing of this feature. What I observed is that sometimes, the idle connections are not closed. The following was what I did. 1. Configure a small connections.max.idle.ms = 10000. 2. start ZK and Kafka broker 3. start a console consumer bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic topic1 --from-beginning 4. start a console producer and type in sth every 15 secs or so. bin/kafka-console-producer.sh --broker-list localhost:9092 --topic topic1 --request-required-acks 1 What I observed was that initially, the producer connections kept getting killed by the broker correctly after being idle for 10 secs. The next producer send would hit an IOException and trigger a resend. However, after typing in 10 or so messages, at some point, no idle connections were killed by the broker any more and the producer send always succeeded. > Disconnect idle socket connection in Selector > --------------------------------------------- > > Key: KAFKA-1282 > URL: https://issues.apache.org/jira/browse/KAFKA-1282 > Project: Kafka > Issue Type: Bug > Components: producer > Affects Versions: 0.8.2 > Reporter: Jun Rao > Assignee: nicu marasoiu > Labels: newbie++ > Fix For: 0.9.0 > > Attachments: 1282_brush.patch, 1282_brushed_up.patch, > KAFKA-1282_Disconnect_idle_socket_connection_in_Selector.patch > > > To reduce # socket connections, it would be useful for the new producer to > close socket connections that are idle.
