SCRIPT-FLUSH(3valkey)

✨ NAME ✨

script-flush — it literally wipes every single server-side Lua script out of the script cache. all of them. gone. bye bestie 💅

---

🎀 SYNOPSIS 🎀

SCRIPT FLUSH [ASYNC | SYNC]

---

🦋 DESCRIPTION 🦋

okay so, this one flushes the Lua scripts cache. like, the whole thing. ngl it's giving "spring cleaning but for your server" 🧹✨

By default, SCRIPT FLUSH will synchronously flush the cache. but here's the tea — if you set the lazyfree-lazy-user-flush configuration directive to “yes”, that changes the default flush mode to asynchronous. so the default is not always the default, iykyk 😭

You can also just say what you want out loud with one of these modifiers, and they'll dictate the flushing mode explicitly:

• ASYNC: flushes the cache asynchronously
• SYNC: flushes the cache synchronously

valkey-protocol(7) Simple string reply: OK.

like. that's it. that's the reply. OK. iconic behaviour honestly 👑

---

🌸 COMPLEXITY 🌸

O(N) with N being the number of scripts in cache

so yeah, the more scripts you hoarded, the longer this takes. no cap 💀
