django-ft-cache

A fault-tolerant pylibmc cache backend for Django

Documentation

By default, a failed cache operation in Django is fatal and will raise a 500 error. In some cases, this might not be desirable behavior. This cache backend will catch failures and log them, but not raise an exception. A cache get that fails will appear to be a miss to the application.

Installation

pip install pylibmc django-ft-cache

Replace the existing pylibmc cache backend in your settings with 'django_ft_cache.FaultTolerantPyLibMCCache'. For example:

CACHES = {
    'default': {
        'BACKEND': 'django_ft_cache.FaultTolerantPyLibMCCache',
        'LOCATION': ['127.0.0.1:11211'],
    },
}

Building Your Own

If you are already using a custom cache backend, a mixin is provided that should add this capability: django_ft_cache.FaultTolerantCacheMixin.
