pip install redis-lruIt's often useful to have an lru redis cache. Of course, it's also desirable not to have the cache grow too large, and cache expiration is often desirable. This module provides such a cache.
redis-lru supports CPython 3.4+
For the most part, you can just use it like this:
import redis
from redis_lru import RedisLRU
client = redis.StrictRedis()
cache = RedisLRU(client)
@cache
def f(x):
print("Calling f({})".format(x))
return x
f(3) # This will print "Calling f(3)", will return 3
f(3) # This will not print anything, but will return 3 (unless 15 minutes have passed between the first and second function call).Additionally a datetime.time object can be provided to clear the cache at a specific time of the day:
@cache(expire_on=datetime.time(hour=8)) # clear at 08:00 o'clock
def b(x):
print("Calling f({})".format(x))
return x
