Usage example

Simple high-level interface with connections pool:

import asyncio
import aioredis

async def go():
    redis = await aioredis.create_redis_pool(
        'redis://localhost')
    await redis.set('my-key', 'value')
    val = await redis.get('my-key', encoding='utf-8')
    print(val)
    redis.close()
    await redis.wait_closed()

asyncio.run(go())
# will print 'value'

Using a pool among multiple coroutine calls:

import asyncio
import string

import aioredis

async def go(r, key, value):
    await r.set(key, value)
    val = await r.get(key)
    print(f"Got {key} -> {val}")

async def main(loop):
    try:
        r = await aioredis.create_redis_pool(
            "redis://localhost", minsize=5, maxsize=10, loop=loop
        )
        return await asyncio.gather(
            *(
                go(r, i, j)
                for i, j in zip(string.ascii_uppercase, string.ascii_lowercase)
            ),
            return_exceptions=True,
        )
    finally:
        r.close()
        await r.wait_closed()

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    res = loop.run_until_complete(main(loop))
