redys

A simple redis-like in pure python3, fully asyncio/thread/process compliant !

on pypi/redys

features

• asyncio compliant
• client Sync (Client) & Async (AClient)
• 100% tested on all platforms ("3.7", "3.8", "3.9", "3.10", "3.11" on ubuntu-latest, macos-latest, windows-latest) NEW
• very quick
• classics commands : get/set/delete/keys & incr/decr
• sets commands : sadd/srem
• queue commands : rpush/lpush/rpop/lpop
• pubsub commands : subscribe/unsubscribe/get_event & publish
• cache commands : setex
• ping() command ;-)
• KILL() command (so a client can kill the server) NEW
• exchange everything that is pickable (except None)
• raise real python exception in client side
• minimal code size
• works well on GAE Standard (2nd generation/py37)
• just in-memory !

why ?

Redis is great, but overbloated for my needs. Redys is simple, you can start the server side in an asyncio loop, and clients can interact with a simple in-memory db. Really useful when clients are in async/threads/process(workers)/multi-hosts world, to share a unique source of truth.

nb

• The sync client (Client) use threads, so it can't live in the same loop as the server (Server). It's better to use it in another thread or process.
• The async client (AClient) can live in the same loop as the server (Server), but don't forget to await each methods (which are coroutines in async version)
• Not fully/concurrency tested. Use at own risk ;-)
• See tests for examples

BTW, I use it in production since 2018: and no problems at all !!!! (it works as excepted)
