This library is not maintained anymore and only supports Kafka 0.6. Please use mumrah/kafka-python if you want Kafka 0.8 support.
brod lets you produce messages to the Kafka distributed publish/subscribe messaging service. It started as a fork of pykafka (https://github.com/dsully/pykafka), but became a total rewrite as we needed to add many features.
It's named after Max Brod, Franz Kafka's friend and supporter.
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 http://incubator.apache.org/kafka/
