cachetools
This module provides various memoizing collections and decorators, including a variant of the Python 3 Standard Library @lru_cache function decorator.
>>> from cachetools import LRUCache
>>> cache = LRUCache(maxsize=2)
>>> cache.update([('first', 1), ('second', 2)])
>>> cache
LRUCache([('second', 2), ('first', 1)], maxsize=2, currsize=2)
>>> cache['third'] = 3
>>> cache
LRUCache([('second', 2), ('third', 3)], maxsize=2, currsize=2)
>>> cache['second']
2
>>> cache['fourth'] = 4
>>> cache
LRUCache([('second', 2), ('fourth', 4)], maxsize=2, currsize=2)For the purpose of this module, a cache is a mutable mapping of a fixed maximum size. When the cache is full, i.e. the size of the cache would exceed its maximum size, the cache must choose which item(s) to discard based on a suitable cache algorithm. A cache’s size is the sum of the size of its items, and an item’s size in general is a property or function of its value, e.g. the result of sys.getsizeof, or len for string and sequence values.
This module provides multiple cache implementations based on different cache algorithms, as well as decorators for easily memoizing function and method calls.
