Atomically sets multiple string keys with an optional shared expiration in a single operation.

## Required arguments

<details open><summary><code>numkeys</code></summary>

The number of keys being set.

</details>

<details open><summary><code>key value [key value ...]</code></summary>

A series of key/value pairs.

</details>

## Optional arguments

<details open><summary><code>condition and expiration flags</code></summary>

The `MSETEX` command supports a set of options that modify its behavior:

* `NX` -- Set the keys and their expiration time only if none of the specified keys exist.
* `XX` -- Set the keys and their expiration time only if all of the specified keys already exist.
* `EX seconds` -- Set the specified expiration time in seconds (a positive integer).
* `PX milliseconds` -- Set the specified expiration time in milliseconds (a positive integer).
* `EXAT unix-time-seconds` -- Set the specified Unix time in seconds (a positive integer) at which the key(s) will expire.
* `PXAT unix-time-milliseconds` -- Set the specified Unix time in milliseconds (a positive integer) at which the key(s) will expire.
* `KEEPTTL` -- Retain the time to live associated with the keys.
