Questions tagged [django-johnny-cache]

Johnny Cache is a caching framework for django applications. It works with the django caching abstraction, but was developed specifically with the use of memcached in mind. Its main feature is a patch on Django’s ORM that automatically caches all reads in a consistent manner. It works with Django 1.1 thru 1.4 and python 2.4 thru 2.7.
