Project description

Latest Version in PyPI CircleCI build status Supported Python versions

An efficient and user-friendly async redis client ported from redis-py (which is a Python interface to the Redis key-value)

To get more information please read full document

Installation

aredis requires a running Redis server.

To install aredis, simply:

$ sudo pip3 install aredis

or alternatively (you really should be using pip though):

$ sudo easy_install aredis

or from source:

$ sudo python setup.py install

Getting started

For more example

single node client

>>> import asyncio
>>> from aredis 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')
>>>
>>> loop = asyncio.get_event_loop()
>>> loop.run_until_complete(example())

cluster client

>>> import asyncio
>>> from aredis 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'
>>>
>>> loop = asyncio.get_event_loop()
>>> loop.run_until_complete(example())
