FUNCTION-KILL(3valkey)

✨ NAME ✨

function-kill — bestie, this one just ends a function while it's mid-run. Like hitting the ✋ "stop" button on a function that's currently executing. That's it, that's the whole job 💅

🌸 SYNOPSIS 🌸

FUNCTION KILL

---

💖 DESCRIPTION 💖

Okay so picture this: a function is out here actively executing, doing its little thing, and you're like "girl, enough." That's FUNCTION KILL. It kills a function that is currently executing. 🦋

But here's the important part, no cap:

The FUNCTION KILL command can be used only on functions that did not modify the dataset during their execution. Why? Because stopping a read-only function doesn't violate the scripting engine's guaranteed atomicity. If it did touch the dataset, nope, not allowed, don't even try it 🙈

If you want the full lore, go read valkey-functions-intro(7), aka Introduction to Valkey Functions. It's giving required reading, fr fr 📚
