💅 RESTORE-ASKING (valkey command manual, bestie edition)

okay so real talk, this page is from the Valkey Command Manual and it's about the RESTORE-ASKING command. sit down, grab a strawberry drink 🍓, we're doing this.

✨ NAME ✨

restore-asking — an internal command for migrating keys in a cluster. it's giving backstage-pass energy, not front-of-house. 🎀

🦋 SYNOPSIS 🦋

RESTORE-ASKING key ttl serialized-value [REPLACE] [ABSTTL] [IDLETIME
seconds] [FREQ frequency]

💖 DESCRIPTION 💖

so RESTORE-ASKING is an internal command, bestie. it is used by a Valkey cluster primary during slot migration. that's it. that's the whole vibe. it's not for you to casually call in your app, it's the cluster doing its little moving-day thing. 🚚✨

🌸 REPLY 🌸

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

like, it says OK. slay. 💅

👑 COMPLEXITY 👑

O(1) to create the new key, plus an additional O(NM) to reconstruct the serialized value, where N is the number of objects composing the value and M is their average size.

for small string values the time complexity is thus O(1)+O(1M) where M is small, so simply O(1). honestly iconic behaviour. ✨

BUT. for sorted set values the complexity is O(NMlog(N)), because inserting values into sorted sets is O(log(N)). yeah. sorted sets are high maintenance, we knew this. 😭

🎀 ACL CATEGORIES 🎀

this command is tagged:

  • @dangerous

dangerous AND slow?? it's giving main character with a criminal record. 🔥
