Ubuntu:

    apt-get install libsnappy-dev

OSX:

    brew install snappy

    cd snappy-1.1.3
    ./configure
    make
    sudo make install

### Install Python Module

Install the python-snappy module

    pip install python-snappy

## Optional crc32c install

Highly recommended if you are using Kafka 11+ brokers. For those kafka-python uses a new message protocol version, that requires calculation of crc32c, which differs from zlib.crc32 hash implementation. By default kafka-python calculates it in pure python, which is quite slow. To speed it up we optionally support https://pypi.python.org/pypi/crc32c package if it’s installed.

    pip install crc32c
