yaaredis (Yet Another Async Redis (client)) is a fork of aredis <https://github.com/NoneGG/aredis>, which itself was ported from redis-py <https://github.com/andymccurdy/redis-py>. yaaredis provides an efficient and user-friendly async redis client with support for Redis Server, Cluster, and Sentinels.

To get more information please read the full documentation_ managed by the upstream aredis repo. We are working on hosting our own as the projects diverge -- stay tuned!

Installation

yaaredis requires a running Redis server. To install yaaredis, simply:

.. code-block:: console

python3 -m pip install yaaredis

or from source:

.. code-block:: console

python3 -m pip install .

Note that yaaredis also supports using hiredis as a drop-in performance improvements. You can either install hiredis separately or make use of the PyPI extra to make use of this functionality:

.. code-block:: console

python3 -m pip install yaaredis[hiredis]

Getting started

We have various examples_ in this repo which you may find useful. A few more specific cases are listed below.

Single Node Client ^^^^^^^^^^^^^^^^^^

.. code-block:: python

import asyncio
from yaaredis import StrictRedis

async def example():
    client = StrictRedis(host='127.0.0.1', port=6379, db=0)
    await client.flushdb()
    await client.set('foo', 1)
    assert await client.exists('foo') is True
    await client.incr('foo', 100)

    assert int(await client.get('foo')) == 101
    await client.expire('foo', 1)
    await asyncio.sleep(0.1)
    await client.ttl('foo')
    await asyncio.sleep(1)
    assert not await client.exists('foo')

asyncio.run(example())

Cluster Client ^^^^^^^^^^^^^^

.. code-block:: python

import asyncio
from yaaredis import StrictRedisCluster

async def example():
    client = StrictRedisCluster(host='172.17.0.2', port=7001)
    await client.flushdb()
    await client.set('foo', 1)
    await client.lpush('a', 1)
    print(await client.cluster_slots())

    await client.rpoplpush('a', 'b')
    assert await client.rpop('b') == b'1'

asyncio.run(example())
