Redis memoize cache
What is it
rcache.py is a cache and works on redis so it is suitable for multi threaded and multi process applications.
It has been inspired and based on
cache.py library https://github.com/bwasti/cache.py
To use the file,
import rcache and annotate functions with
import rcache @rcache.rcache() def expensive_func(arg, kwarg=None): # Expensive stuff here return arg
@rcache.rcache() function can take multiple arguments.
@rcache.rcache(timeout=20)- Only caches the function for 20 seconds.
@rcache.rcache(url="http://other_redis:6379")- Saves cache to specified Redis url (defaults to
@rcache.rcache(key=rcache.ARGS[KWARGS,NONE])- Check against args, kwargs or neither of them when doing a cache lookup.
How it works
redis and checks against the name, arguments and hash of a function's source
to decide if the function has been run before. If it has it returns the cached result immediately.
