A simple caching library for Python

Simple Caching Library for Python

Summary

Simple caching library for supported providers. Pass method call to caching provider along with generated key to populate memcached with the result. The results will be returned with a boolean value if there was a cache miss to assist in any metrics generation.

Versions

0.0.1 - Support for memcached and json conversion

Getting Started

1. Instantiate the provider:

   from simplecache.common.json_conversion import JsonConversion
   from simplecache.providers.memcached import MemcachedProvider
   
   memcached = MemcachedProvider(JsonConversion(), servers='127.0.0.1')
   

2. PUT data into Memcached:

   data = {
       'test1': 'value1',
       'test2': 'value2'
   }
   
    memcached.put('testkey1', 60, data) 
   

3. GET data by key from provider. Optionally: Pass a method for a cache miss to load data into provider from the result.

    class TestClass(object):
   
        def test_method(self, param1, param2):
            data = {
                'test1': 'value1',
                'test2': 'value2'
            }
            if param1 != 'p1' or param2 != 'p2':
                raise Exception('Unexpected error.')
            return data
   
    t = TestClass()
   
    # test local instance of memcached with cache miss
    response, miss = memcached.get(
        'testkey2', 60, t.test_method, param1='p1', param2='p2')
   

4. DELETE data by key from provider.

    memcached.delete('testkey1')
