This module provides low-level protocol support for Apache Kafka as well as high-level consumer and producer classes. Request batching is supported by the protocol as well as broker-aware request routing. Gzip and Snappy compression is also supported for message sets.

Compatible with Apache Kafka 0.8.0

I'm following the version numbers of Kafka, plus one number to indicate the version of this project. The current version is 0.8.0-1. This version is under development, APIs are subject to change.

from kafka.client import KafkaClient
from kafka.consumer import SimpleConsumer
from kafka.producer import SimpleProducer

kafka = KafkaClient("localhost", 9092)

producer = SimpleProducer(kafka, "my-topic")
producer.send_messages("some message")
producer.send_messages("this method", "is variadic")

consumer = SimpleConsumer(kafka, "my-group", "my-topic")
for message in consumer:
    print(message)

kafka.close()

from kafka.client import KafkaClient
kafka = KafkaClient("localhost", 9092)
req = ProduceRequest(topic="my-topic", partition=1,
    messages=[KafkaProdocol.encode_message("some message")])
resps = kafka.send_produce_request(payloads=[req], fail_on_error=True)
kafka.close()

resps[0].topic      # "my-topic"
resps[0].partition  # 1
resps[0].error      # 0 (hopefully)
resps[0].offset     # offset of the first message sent in this request

Install with your favorite package manager

Pip:

git clone https://github.com/mumrah/kafka-python
pip install ./kafka-python

Setuptools:

git clone https://github.com/mumrah/kafka-python
easy_install ./kafka-python

Using setup.py directly:

git clone https://github.com/mumrah/kafka-python
cd kafka-python
python setup.py install

Download and build Snappy from http://code.google.com/p/snappy/downloads/list

wget http://snappy.googlecode.com/files/snappy-1.0.5.tar.gz
tar xzvf snappy-1.0.5.tar.gz
cd snappy-1.0.5
./configure
make
sudo make install

Install the python-snappy module

pip install python-snappy

Some of the tests will fail if Snappy is not installed. These tests will throw NotImplementedError. If you see other failures, they might be bugs - so please report them!

These are broken at the moment

python -m test.unit

First, checkout the Kafka source

git submodule init
git submodule update
cd kafka-src
./sbt update
./sbt package

Next start up a ZooKeeper server on localhost:2181

/opt/zookeeper/bin/zkServer.sh start

This will actually start up real Kafka brokers and send messages in using the client.
