MSET · Valkey

MSET

Atomically creates or modifies the string values of one or more keys.

Usage

MSET key value [key value …]

Description

Sets the given keys to their respective values. MSET replaces existing values with new values, just as regular SET. See MSETNX if you don’t want to overwrite existing values.

MSET is atomic, so all given keys are set at once. It is not possible for clients to see that some of the keys were updated while others are unchanged.

Reply

Simple string reply: always OK because MSET can’t fail.

Complexity

O(N) where N is the number of keys to set.
