redis MSET command syntax

Function:Set one or more key-value pairs at the same time. If a given key already exists, then MSET will overwrite the old value with the new value. If this is not what you want, consider using the MSETNX command: it will only work if all the given keys do not exist. Perform setting operations.

Syntax: MSET key value [key value ...]

Description: MSET is an atomic operation, all given Certain keys will be set at the same time. It is impossible for some given keys to be updated while other given keys have not changed.

Available versions: >= 1.0.1

Time complexity: O(N), N is the number of keys to be set.
