Usage examples

Simple low-level interface:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

@asyncio.coroutine
def go():
    conn = yield from aioredis.create_connection(
        ('localhost', 6379), loop=loop)
    yield from conn.execute('set', 'my-key', 'value')
    val = yield from conn.execute('get', 'my-key')
    print(val)
    conn.close()
loop.run_until_complete(go())
# will print 'value'

Simple high-level interface:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

@asyncio.coroutine
def go():
    redis = yield from aioredis.create_redis(
        ('localhost', 6379), loop=loop)
    yield from redis.set('my-key', 'value')
    val = yield from redis.get('my-key')
    print(val)
    redis.close()
loop.run_until_complete(go())
# will print 'value'

Connections pool:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

@asyncio.coroutine
def go():
    pool = yield from aioredis.create_pool(
        ('localhost', 6379),
        minsize=5, maxsize=10,
        loop=loop)
    with (yield from pool) as redis:    # high-level redis API instance
        yield from redis.set('my-key', 'value')
        print((yield from redis.get('my-key')))
    yield from pool.clear()    # closing all open connections

loop.run_until_complete(go())

Requirements

• Python 3.3+
• asyncio or Python 3.4+
• hiredis

Note

hiredis is preferred requirement. Pure-python fallback protocol parser is TBD.
