asyncio (PEP 3156) Redis support

asyncio (PEP 3156) Redis support

Documentation

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')))
    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.

Changes

0.2.4 (xxxx-xx-xx)

0.2.3 (2015-08-14)

• Redis cluster support work in progress;

• Fixed pool issue causing pool growth over max size & acquire call hangs (see https://github.com/aio-libs/aioredis/issues/71);

• info server command result parsing implemented;

• Fixed behavior of util functions (see https://github.com/aio-libs/aioredis/issues/70);

• hstrlen command added;

• Few fixes in examples;

• Few fixes in documentation;

0.2.2 (2015-07-07)

• Decoding data with encoding paramter now takes into account list (array) replies (see https://github.com/aio-libs/aioredis/pull/68);

• encoding parameter added to following commands: - generic commands: keys, randomkey; - hash commands: hgetall, hkeys, hmget, hvals; - list commands: blpop, brpop, brpoplpush, lindex, lpop, lrange, rpop, rpoplpush; - set commands: smembers, spop, srandmember; - string commands: getrange, getset, mget;

• Backward incompatibility:

  ltrim command now returns bool value instead of ‘OK’;

• Tests updated;

0.2.1 (2015-07-06)

• Logging added (aioredis.log module);

• Fixed issue with wait_message in pub/sub (see https://github.com/aio-libs/aioredis/issues/66);

0.2.0 (2015-06-04)

• Pub/Sub support added;

• Fix in zrevrangebyscore command (see https://github.com/aio-libs/aioredis/pull/62);

• Fixes/tests/docs;

0.1.5 (2014-12-09)

• AutoConnector added;

• wait_closed method added for clean connections shutdown;

• zscore command fixed;

• Test fixes;

0.1.4 (2014-09-22)

• Dropped following Redis methods – Redis.multi(), Redis.exec(), Redis.discard()

• Redis.multi_exec hack’ish property removed

• Redis.multi_exec() method added

• High-level commands implemented:

  • generic commands (tests);

  • transactions commands (api stabilization).

• Backward incompatibilities:

  • Following sorted set commands’ API changed:

    zcount, zrangebyscore, zremrangebyscore, zrevrangebyscore;

  • set string command’ API changed;

0.1.3 (2014-08-08)

• RedisConnection.execute refactored to support commands pipelining (see http://github.com/aio-libs/aioredis/issues/33);

• Several fixes;

• WIP on transactions and commands interface;

• High-level commands implemented and tested:

  • hash commands;

  • hyperloglog commands;

  • set commands;

  • scripting commands;

  • string commands;

  • list commands;

0.1.2 (2014-07-31)

• create_connection, create_pool, create_redis functions updated: db and password arguments made keyword-only (see http://github.com/aio-libs/aioredis/issues/26);

• Fixed transaction handling (see http://github.com/aio-libs/aioredis/issues/32);

• Response decoding (see http://github.com/aio-libs/aioredis/issues/16);

0.1.1 (2014-07-07)

• Transactions support (in connection, high-level commands have some issues);

• Docs & tests updated.

0.1.0 (2014-06-24)
