Differences between aioredis and asyncio-redis about aioredis-py HOT 4 CLOSED

Oh, well)

• First of all I tried to make it simplier -- asyncio_redis implements asyncio.Protocol (lots of code) vs aioredis uses asyncio.StreamReader/StreamWriter (no protocol code; just read & send);
• At the moment when I started aioredis asyncio-redis had no hiredis parser.
• asyncio_redis API forces end-user to work with one type of data, ie only bytes or only unicode or etc. So you would receive an error trying to mix data types, say set('unicode_key', b'encoded_bytes_data').
• asyncio-redis has no way to execute raw command; aioredis provides execute method so you'll be able to use new redis commands before their shortcuts/API implemented by client lib.
• "automatic reconnections", well, in asyncio-redis if the server has gone away would reconnect, reconnect and reconnect. I mean reconnection is done as soon as connection is lost which is bad. For instance we had functional tests infrastructure where we were starting & shutting down standalone redis server instance so after all tests we had several hundreds of spamy errored 'reconnect' messages.
• aioredis doesn't have pub/sub yet, but it is in progress and will be implemented soon.

How does aioredis handle disconnections ?

I'm having trouble with asyncio-redis not closing connections.
Redis says it has reached the max number of clients. But most of them are ghosts.

Do you think aioredis is better at handling those ?

Also, does aioredis support async with ?

from aioredis-py.

@lux-lth I suggest you open a new issue - connection pool leaks sound like a bug. And on the off chance it's a misuse of the connection pool, improved documentation from the issue resolution would help others.

Hi, @lux-lth ,

aioredis handles connections well — drops closed, opens new when needed, reuse already opened. All that is handled by aioredis.ConnetionsPool.
You should check aioredis.create_redis_pool.

Also, does aioredis support async with ?

It is supported in terms of acquiring connection from pool and releasing it back,
so that no other coroutine will use same connection (this is mostly needed if you want to send some blocking command). Is this what you asked?
