Project description

asyncio (PEP 3156) Redis client library.

https://travis-ci.org/aio-libs/aioredis.svg?branch=master https://codecov.io/gh/aio-libs/aioredis/branch/master/graph/badge.svg https://ci.appveyor.com/api/projects/status/wngyx6s98o6hsxmt/branch/master?svg=true

Features

hiredis parser Yes
Pure-python parser Yes
Low-level & High-level APIs Yes
Connections Pool Yes
Pipelining support Yes
Pub/Sub support Yes
SSL/TLS support Yes
Sentinel support Yes [1]
Redis Cluster support WIP
Trollius (python 2.7) No
Tested CPython versions 3.3, 3.4, 3.5, 3.6
Tested PyPy3 versions 5.7.1
Tested for Redis server 2.6, 2.8, 3.0, 3.2
Support for dev Redis server through low-level API
[1]Sentinel support is available in master branch. This feature is not yet stable and may have some issues.

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

Note

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

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:

  • Implement Geo commands support (see #177 and #179);

FIX:

  • Minor tests fixes;

MISC:
