This is kafka.go, a repository containing Go bindings for the Apache Kafka pub/sub messaging system developed by LinkedIn. The bindings were originally authored by @jdamick but have largely been abandoned; I brought them up to date for Go 1 for my needs at work. Since that implied reorganizing the repository, I have elected to maintain a separate repository instead of issuing a pull request and disrupting that codebase.

The original documentation, mostly, follows.

The import path for kafka.go is github.com/jedsmith/kafka.

$ export GOPATH=`pwd`
$ go get github.com/jedsmith/kafka
$ go test github.com/jedsmith/kafka
ok     github.com/jedsmith/kafka      0.037s

To play around with publishers and consumers, there are also example binaries. Assuming a running Kafka server on your local machine:

$ go get github.com/jedsmith/kafka/examples/consumer
$ go get github.com/jedsmith/kafka/examples/producer

$ bin/producer -topic test -message "sup"
$ bin/consumer -topic test -consumeforever

2012/09/14 15:28:00 ----- Begin Message ------
2012/09/14 15:28:00 magic: 0
2012/09/14 15:28:00 checksum: ABBBF394
2012/09/14 15:28:00 payload: 737570
2012/09/14 15:28:00 payload(string): sup
2012/09/14 15:28:00 offset: 0
2012/09/14 15:28:00 ----- End Message ------

broker := kafka.NewBrokerPublisher("localhost:9092", "mytesttopic", 0)
broker.Publish(kafka.NewMessage([]byte("tesing 1 2 3")))

broker := kafka.NewBrokerConsumer("localhost:9092", "mytesttopic", 0, 0, 1048576)
broker.Consume(func(msg *kafka.Message) { msg.Print() })

Or, the consumer can use a channel-based approach:

broker := kafka.NewBrokerConsumer("localhost:9092", "mytesttopic", 0, 0, 1048576)
go broker.ConsumeOnChannel(msgChan, 10, quitChan)

broker := kafka.NewBrokerOffsetConsumer("localhost:9092", "mytesttopic", 0)
offsets, err := broker.GetOffsets(-1, 1)
