An easy-to-use cache module

How to use

Run pip install mecache or pipenv install mecache to install.

Built-in three cache modes, memory cache mode, file cache mode, redis cache mode.

You can control the time of cache failure by using the cache parameters.

memory modes

from mecache import Memory

memory = Memory("CACHE_PATH")

# Cache failure after 60 seconds
@memory.cache(60)
def do(x, y):
    import time
    time.sleep(2)
    return x+y

redis modes

from mecache import Redis

# Refer to https://redis-py.readthedocs.io/en/latest/ for all parameters
redis = Redis(host="127.0.0.1", port='6379', db=0, password="password")

# Cache failure after 60 seconds
@redis.cache(60)
def do(x, y):
    import time
    time.sleep(2)
    return x+y

file modes

from mecache import File

# CACHE_PATH like '/var/tmp/test-cache'
file = File("CACHE_PATH")

# Cache failure after 60 seconds
@file.cache(60)
def do(x, y):
    import time
    time.sleep(2)
    return x+y

Advanced usage

If the parameters of a function are difficult to serialize using pickle, you can specify the rules that generate key by customizing keyf. The return value of the function keyf must be a string.

# a example in django view function

def key_by_user(request):
    return request.user.username

@memory.cache(60*60, keyf=key_by_user)
def home(request):
    return render(request, 'home.html')
