I would like to dynamically set the maxsize of python lru_cache, but when I wrap a function (A._get) in antoher function (A.get), the cache doesn't work. The original use of lru_cache (A._get2) works properly.
from functools import partial, lru_cache, wraps
lru_cache_maxsize = 5
class A:
@staticmethod
def _get(func_name: str, date: str, **params):
time.sleep(1)
return func_name, date, params
@staticmethod
def get(func_name: str, date: str, **params):
maxsize = params.pop("maxsize", lru_cache_maxsize)
# print(maxsize)
return lru_cache(maxsize=maxsize)(A._get)(func_name, date, **params)
@staticmethod
@lru_cache(maxsize=5)
def _get2(func_name: str, date: str, **params):
time.sleep(1)
return func_name, date, params
method 1 (Not working)
for i in range(10):
for n in range(5):
ret = A.get("func1", str(n))
print(ret)
method 2 (This works, but I want to dynamically set the maxsize)
for i in range(10):
for n in range(5):
ret = A._get2("func1", str(n))
print(ret)
[update]:
I found the asnwers, and posted the links below.
disable `functools.lru_cache` from inside function
Python functools lru_cache with instance methods: release object
