Usage examples

Simple low-level interface:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

async def go():
    conn = await aioredis.create_connection(
        'redis://localhost', loop=loop)
    await conn.execute('set', 'my-key', 'value')
    val = await conn.execute('get', 'my-key')
    print(val)
    conn.close()
    await conn.wait_closed()
loop.run_until_complete(go())
# will print 'value'

Simple high-level interface:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

async def go():
    redis = await aioredis.create_redis(
        'redis://localhost', loop=loop)
    await redis.set('my-key', 'value')
    val = await redis.get('my-key')
    print(val)
    redis.close()
    await redis.wait_closed()
loop.run_until_complete(go())
# will print 'value'

Connections pool:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

async def go():
    pool = await aioredis.create_pool(
        'redis://localhost',
        minsize=5, maxsize=10,
        loop=loop)
    await pool.execute('set', 'my-key', 'value')
    print(await pool.execute('get', 'my-key'))
    # graceful shutdown
    pool.close()
    await pool.wait_closed()

loop.run_until_complete(go())

Simple high-level interface with connections pool:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

async def go():
    redis = await aioredis.create_redis_pool(
        'redis://localhost',
        minsize=5, maxsize=10,
        loop=loop)
    await redis.set('my-key', 'value')
    val = await redis.get('my-key')
    print(val)
    redis.close()
    await redis.wait_closed()
loop.run_until_complete(go())
# will print 'value'

Requirements

• Python 3.5.3+
• hiredis

Note

hiredis is preferred requirement. Pure-python protocol parser is implemented as well and can be used through parser parameter.
