💖 CLUSTER-CANCELSLOTMIGRATIONS 💖

okay bestie, welcome to the Valkey Command Manual, section 3valkey — yes the title is literally CLUSTER-...GRATIONS(3valkey) because manpage headers love to be mysterious, but the actual star of the show is cluster-cancelslotmigrations, and she is so iconic for a command that's basically a big red "stop 🛑" button. no cap.

✨ NAME ✨

cluster-cancelslotmigrations — cancel all current ongoing slot migration operations. like, all of them. every single one. bye 👋

🎀 SYNOPSIS 🎀

CLUSTER CANCELSLOTMIGRATIONS

that's it. no args, no flags, no drama. she just does the thing. 💅

🌸 DESCRIPTION 🌸

so CLUSTER CANCELSLOTMIGRATIONS cancels all in progress valkey-atomic-slot-migration(7) atomic slot migrations that were initiated through valkey-cluster-migrateslots(7) CLUSTER MIGRATESLOTS.

and here's the important part, bestie, don't skip this — only slot migrations initiated on this node get cancelled. if this node is the target of a slot migration, then the cancellation has to be performed on the source node instead. it's giving "you can't cancel somebody else's party from the wrong house" 🫶

🫠 lowkey crucial: wrong node = nothing happens. check where the migration started, fr fr.

👑 COMPLEXITY 👑

O(N), where N is the number of slot migration operations being cancelled. so the more migrations you're shutting down, the more work it is. math is math. ✨
