kafka-rb
kafka-rb allows you to produce messages to the Kafka distributed publish/subscribe messaging service.
Requirements
You need to have access to your Kafka instance and be able to connect through TCP. You can obtain a copy and instructions on how to setup kafka at https://github.com/kafka-dev/kafka
Installation
sudo gem install kafka-rb
(the code works fine with JRuby, Ruby 1.8x and Ruby 1.9.x)
Usage
Sending a simple message
require 'kafka'
producer = Kafka::Producer.new
message = Kafka::Message.new("some random message content")
producer.send(message)
Sending a sequence of messages
require 'kafka'
producer = Kafka::Producer.new
message1 = Kafka::Message.new("some random message content")
message2 = Kafka::Message.new("some more content")
producer.send([message1, message2])
Batching a bunch of messages using the block syntax
require 'kafka'
producer = Kafka::Producer.new
producer.batch do |messages|
puts "Batching a send of multiple messages.."
messages << Kafka::Message.new("first message to send")
messages << Kafka::Message.new("second message to send")
end
- they will be sent all at once, after the block execution
Consuming messages one by one
require 'kafka'
consumer = Kafka::Consumer.new
messages = consumer.consume
Consuming messages using a block loop
require 'kafka'
consumer = Kafka::Consumer.new
consumer.loop do |messages|
puts "Received"
puts messages
end
