Redis memoize cache

Project description

rcache.py

pipeline status

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

Usage

To use the file, import rcache and annotate functions with @rcache.rcache().

import rcache

@rcache.rcache()
def expensive_func(arg, kwarg=None):
  # Expensive stuff here
  return arg

The @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 http://localhost:6379)
  • @rcache.rcache(key=rcache.ARGS[KWARGS,NONE]) - Check against args, kwargs or neither of them when doing a cache lookup.

How it works

rcache.py queries 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.
