jitcache

jitcache is a just-in-time key-value cache that is thread/process safe. jitcache also prevents repeated computation when multiple workers request the same value.

jitcache was designed to improve the performance of Plot.ly Dash apps by caching results and reducing CPU load.

Installation

$ pip install jitcache

Example Usage

Notice that slow_fn is only called once, despite two requests.

from cache import KVStore
import time
import json

store = KVStore()

def slow_fn(input_1, input_2):
    print("Slow Function Called")
    time.sleep(1)
    return input_1 * input_2

kwarg_dict = {
    'input_1': 10,
    'input_2': 4
}

# Make a unique identifier for this object
key = json.dumps(kwarg_dict, sort_keys=True)

# Insert a value with corresponding key
value1 = store.get_value(key, slow_fn, kwarg_dict)

value2 = store.get_value(key, slow_fn, kwarg_dict)

print(value1), print(value2)

Output:

Slow Function Called
