Build Status

Django-BMemcached

A django cache backend to use bmemcached module which supports memcached binary protocol with authentication.

Installing

Use pip:

pip install django-bmemcached

Using

In your settings.py add bmemcached as backend:

CACHES = {
    'default': {
        'BACKEND': 'django_bmemcached.memcached.BMemcached',
        'LOCATION': 'your_server:port',
    }
}

If you are using Django 1.11 or above, you can also add OPTIONS which will be passed through to the client. The options available for BMemcached are as follows:

CACHES = {
    'default': {
        'BACKEND': 'django_bmemcached.memcached.BMemcached',
        'LOCATION': 'your_server:port',
        'OPTIONS': {
            'username': 'user',
            'password': 'password',
            'compression': None,
            'socket_timeout': bmemcached.client.constants.SOCKET_TIMEOUT,
            'pickler': pickle.Pickler,
            'unpickler': pickle.Unpickler,
            'pickle_protocol': 0
        }
    }
}

NB If you have options in your configuration that are not supported (see the sample above, or django_bmemcached.memcached.VALID_CACHE_OPTIONS) the cache will raise an InvalidCacheOptions error the first time it is accessed:

>>> from django_bmemcached import BMemcached
>>> client = BMemcached(None, {'OPTIONS': {'bad_option': True}})
>>> client.get("foo")
Traceback (most recent call last):
...
django_bmemcached.memcached.InvalidCacheOptions: Error initialising BMemcached - invalid options detected: {'bad_option'}
Please check your CACHES config contains only valid OPTIONS: {'username', 'unpickler', 'compression', 'pickle_protocol', 'password', 'pickler', 'socket_timeout'}
>>>

Using in Heroku

Just add bmemcached as backend. It will work automagically if you have added memcached as Heroku addon.

CACHES = {
    'default': {
        'BACKEND': 'django_bmemcached.memcached.BMemcached'
    }
}
