Here's an example of the error: This module provides various memoizing collections and decorators, including variants of the Python Standard Library’s @lru_cache function decorator.. For the purpose of this module, a cache is a mutable mapping of a fixed maximum size. This class discards the least recently used items first to make space when necessary. If you can use the decorator version of LRUCache, that's preferred since it has built-in locking. Let’s see how we can use it in Python 3.2+ and the versions before it. 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. 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. This module provides various memoizing collections and decorators, including variants of the Python 3 Standard Library @lru_cache function decorator. This is mostly due to the GIL, which will help avoid some of the more serious threading issues.
