An redis python datastructures package.

redis-cooker

An redis python datastructures package

Installation

To install redis-cooker, simply:

$ pip install redis-cooker

or from source:

$ python setup.py install

Getting Started

>>> from redis_cooker.clients import set_connection_url
>>> from redis_cooker.collections import RedisList
>>>
>>> set_connection_url('redis://:@127.0.0.1:6379/15')
>>> for i in RedisList("Testing:RedisList", init=['Hello', 'World']):
>>>     print(i)
Hello
World

By default, all data will use the built-in json serializer.

Attention!

• If the key has existed in Redis, new object will connect to the existed key and ignore the "init" value.
• For complex operations, redis-cooker uses lua instead of python.

Datastructures

redis-cooker provide 6 datastructures in current version:

• collections: RedisMutableSet, RedisString, RedisList, RedisDict, RedisDeque, RedisDefaultDict
• others: ABNTest

Integration with Pydantic

>>> from typing import List
>>>
>>> from pydantic import BaseModel
>>> from redis_cooker.clients import set_connection_url
>>> from redis_cooker.collections import RedisList
>>>
>>> set_connection_url('redis://:@127.0.0.1:6379/15')
>>>
>>>
>>> class Person(BaseModel):
        name: str
        age: int
>>>
>>>
>>> data = [{"name": "A", "age": 15},{"name": "B", "age": "16"}]
>>> for i in RedisList("Testing:Pydantic", init=data, schema=Person):
>>>     print(i)
{'name': 'A', 'age': 15}
{'name': 'B', 'age': '16'}

Integration with DRF Serializer

>>> from typing import List
>>>
>>> from rest_framework import serializers
>>> from redis_cooker.clients import set_connection_url
>>> from redis_cooker.collections import RedisList
>>>
>>> set_connection_url('redis://:@127.0.0.1:6379/15')
>>>
>>>
>>> class DRFPerson(serializers.Serializer):
        name = serializers.CharField()
        age = serializers.IntegerField()
>>>
>>>
>>> data = [{"name": "A", "age": 15},{"name": "B", "age": "16"}]
>>> for i in RedisList("Testing:DRF", init=data, schema=DRFPerson):
>>>     print(i)
OrderedDict([('name', 'A'), ('age', 15)])
OrderedDict([('name', 'B'), ('age', 16)])

Use ABNTest in your internal A/B Test

>>> from redis_cooker.abn_test import ABNTest, Choice
>>> from redis_cooker.clients import current_redis_client, set_connection_url
>>>
>>> set_connection_url('redis://:@127.0.0.1:6379/15')
>>> client = current_redis_client()
>>>
>>> topic = "lead comment"
>>> choices = [Choice(name="A", value=5), Choice(name="B", value=5), Choice(name="C", value=2)]
>>> abn_test = ABNTest(topic, choices)
>>> choice = abn_test.fetch()
