Usage examples
Simple low-level interface:
import asyncio
import aioredis
loop = asyncio.get_event_loop()
async def go():
conn = await aioredis.create_connection(
('localhost', 6379), 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(
('localhost', 6379), 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(
('localhost', 6379),
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())Requirements

Changes
1.0.0 (2017-xx-xx)
NEW:
Connections pool has been refactored; now create_redis function will yield Redis instance instead of RedisPool (see #129);
Dropped create_reconnecting_redis, create_redis_pool should be used instead;
Implement Sentinel support (see #181);
Implement pure-python parser (see #212);
Add migrate_keys command (see #187);
Add zrevrangebylex command (see #201);
Add command, command_count, command_getkeys and command_info commands (see #229);
FIX:
Fix critical bug in patched asyncio.Lock (see #256);
Fix Multi/Exec transaction canceled error (see #225);
Add missing arguments to create_redis and create_redis_pool;
Fix deprecation warning (see #191);
Make correct __aiter__() (see #192);
Backward compatibility fix for with (yield from pool) as conn: (see #205);
Fixed pubsub receiver stop() (see #211);
MISC:
Multiple test fixes;
Add PyPy3 to build matrix;
Update dependencies versions;
0.3.2 (2017-06-21)
NEW:
Added zrevrangebylex command (see #201), cherry-picked from master;
Add connection timeout (see #221), cherry-picked from master;
FIX:
0.3.1 (2017-05-09)
FIX:
Fix pubsub Receiver missing iter() method (see #203);
0.3.0 (2017-01-11)
NEW:
Pub/Sub connection commands accept Channel instances (see #168);
Implement new Pub/Sub MPSC (multi-producers, single-consumer) Queue – aioredis.pubsub.Receiver (see #176);
