rediscache-decorator 1.0

Using redis as external rediscache_decorator with one line of code

Important Note :

This repo is widely based on https://github.com/louisLouL/louisPy Yet, for deployment purposes (esp. AWS Lambda), it relies too heavily on pandas.

Quick start

Install

pip install rediscache_decorator

Initialize

from rediscache_decorator import Cache
from redis import StrictRedis
redis = StrictRedis(decode_responses=True)
cache = Cache(redis)

Examples

Make sure you have redis up and running.(https://redis.io/)

Example1 : Cache string return

from time import sleep
from datetime import datetime
@cache.ttl(300)
def pseudo_calc():
    sleep(1)
    print("Computation in progress")
    return str(datetime.now())

for i in range(10):
    print(pseudo_calc())

Example 3: Cache dict

@cache.dict(60)
def return_a_dict(*args, **kwargs):
    sleep(1)
    print("Computation in progress")
    return {"now": str(datetime.now())}


for i in range(5):
    print(return_a_dict())

Example 4: Cache float number

@cache.float(60)
def return_a_float(*args, **kwargs):
    return random()


for i in range(5):
    print(return_a_float())

Delete Cache

# Delete cache by function and signature
cache.delete_cache(return_a_float, 2, b=3) 
# Delete cache by function
cache.delete_cache(return_a_float)
# Delete all caches
cache.delete_cache()
