Python API for the Kafka Message Queue

pykafka

pykafka 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

pip install pykafka

Usage

Sending a simple message

import kafka

producer = kafka.producer.Producer('test')
message  = kafka.message.Message("Foo!")
producer.send(message)

Sending a sequence of messages

import kafka

producer = kafka.producer.Producer('test')
message1 = kafka.message.Message("Foo!")
message2 = kafka.message.Message("Bar!")
producer.send([message1, message2])

Batching a bunch of messages using a context manager.

import kafka
producer = kafka.producer.Producer('test')

with producer.batch() as messages:
  print "Batching a send of multiple messages.."
  messages.append(kafka.message.Message("first message to send")
  messages.append(kafka.message.Message("second message to send")

• they will be sent all at once, after the context manager execution.

Consuming messages one by one

import kafka
consumer = kafka.consumer.Consumer('test')
messages = consumer.consume()

Consuming messages using a generator loop

import kafka

consumer = kafka.consumer.Consumer('test')

for message in consumer.loop():
  print message
