keywrapper

Extremely simple key-value storage wrapper

Motivation

I usually use Redis for small projects with a dynamic storage component. Most of the times I just need a very simple key-value storage and Redis does a terrific job with that. However not all the applications need a high performance storage but just being very easy to start using them.

The idea of this wrapper is to start using a serverless JSON based storage. In the future, if better performance ins required, move the storage of an application to Redis or any other supported driver without changing a single line of code.

Installation

sudo pip install keywrapper

Basic usage

JSON store:

import keywrapper

store = keywrapper.new_store('json')

store.set_value('foo', 'bar', '42')

store.get_value('foo', 'bar')

Redis store:

import keywrapper

store = keywrapper.new_store('redis')

store.set_value('foo', 'bar', '42')

store.get_value('foo', 'bar')

Migrate from JSON store to Redis store:

import keywrapper

json_store = keywrapper.new_store('json')
redis_store = keywrapper.new_store('redis')

redis_store.restore(json_store.dump())

Current status

These are the current implemented features:

• JSON and Redis drivers
• Hash style data type (key, attribute, value)
• set_value and get_value functions
• dump function implemented only in JSON driver
• restore function implemented in both JSON and Redis drivers
