Can you use Lua scripting to make Redis throw events?

I'm trying to create an abstraction where I can listen to change events of a redis collection and have the key, value passed into a callback. I was wondering if it would be possible to do this with Lua scripting on the newer versions.

Thanks!

You can certainly publish events from Lua scripts, and you could certainly poll. The right way to solve your problem would be to publish to a pubsub channel every time you change the set.

No, you can't.

Since Redis is single threaded, your lua script must return quickly. Listening to change of events requires a long running process, and lua scripting is just not designed for that use case.

Take a look at my answer to your other question - listen for changes in redis
