What I don't want to get into is mirroring the config options of some third party system, or doing things like setting defaults. Other kinds of cache that are available in the cachetools package are: the LFUCache (Least Frequently Used), that counts how often an item is retrieved, and discards the items used least often to make space when necessary. the LRUCache (Least Recently Used), that discards the least recently used items first to make space when necessary. Well a lot of operations in Python are thread-safe by default, so a standard dictionary should be ok (at least in certain respects). class cachetools.LRUCache(maxsize, missing=None, getsizeof=None) Least Recently Used (LRU) cache implementation. Also, since LRUCache is modified when values are gotten from it, you will also need to make sure you're locking when you get values from cache too. This is mostly due to the GIL, which will help avoid some of the more serious threading issues. Contribute to tkem/cachetools development by creating an account on GitHub. There's a bunch of that in this PR right now. Gallery About Documentation Support ⦠26.1. popitem() Remove and return the (key, value) pair least recently used.

This module provides various memoizing collections and decorators, including variants of the Python Standard Library's @lru_cache function decorator. class cachetools. When the cache is full, i.e. If you can use the decorator version of LRUCache, that's preferred since it has built-in locking. Letâs see how we can use it in Python 3.2+ and the versions before it. In Python 3.2+ there is an lru_cache decorator which allows us to quickly cache and uncache the return values of a function. Before Python 3.2 we had to write a custom implementation.
