MSET stores each value at its key, overwriting existing values of any type and clearing their time to live, as SET does. All keys are written together: no client sees some of them set and others not yet. If a key is named twice, the last value wins.

In a cluster, all keys must hash to the same slot.

Return value

Section titled “Return value”
Case RESP2 RESP3
Always Simple string OK Simple string OK

An odd number of arguments after the command name is an ERR wrong number of arguments for 'mset' command error.
