FUNCTION-RESTORE(3valkey)

✨ FUNCTION-RESTORE ✨

okay bestie, welcome to FUNCTION-RESTORE(3valkey) 💖 this is a page from the Valkey Command Manual and it's about putting your whole function library situation back from a payload. yes. we're doing this. 🫶

---

💅 NAME

function-restore — restores all libraries from a payload. that's it. that's the job. 👑

---

🎀 SYNOPSIS

FUNCTION RESTORE serialized-value [FLUSH | APPEND | REPLACE]

---

🌸 DESCRIPTION

Restore libraries from the serialized payload. bringing your little library babies back home 🏠✨

You can use the optional policy argument to provide a policy for handling existing libraries. The following policies are allowed:

• APPEND — appends the restored libraries to the existing libraries and aborts on collision. This is the default policy. (so if you don't say anything, this is what you get, and if there's a name clash it just gives up 😭)
• FLUSH — deletes all existing libraries before restoring the payload. scorched earth, no survivors, clean slate 💀🔥
• REPLACE — appends the restored libraries to the existing libraries, replacing any existing ones in case of name collisions. Note that this policy doesn't prevent function name collisions, only libraries. (so like. it'll swap out libraries with the same name but it is NOT out here saving you from function-level clashes, ok? be aware.)

💬 REPLY

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

just OK. simple. clean. iconic. ✨

---

⚡ COMPLEXITY

O(N) where N is the number of functions on the payload

so like, the more functions you packed in there, the more work it is. math is math 🧮
