Hi everyone, could you please recommend a reactivate flow connector to Redis based on kotlin coroutines? Thanks

Lettuce with coroutines adapters (there's for CompleteableFuture, rx, etc as separate artifacts in the coroutines lib, you can probably find something that lettuce supports)

would recommend something for ZeroMQ as well?

I am extremely happy with Redisson https://github.com/redisson/redisson It is 'pure java' (not kotlin), so is not integrated with coroutines specifically. Due to its consistent sync/async set of APIs it works well with standard async adaptors. If you use a kotlin friendly serialization ("codec" ) like jackson+kotlin you can directly map native kotlin objects to redis data .
