GETEX key [EX seconds|PX milliseconds|EXAT timestamp|PXAT milliseconds-timestamp|PERSIST]

Available since 6.2.0.

Time complexity: O(1)

Get the value of key and optionally set its expiration. GETEX is similar to GET, but is a write command with additional options.

*Options

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

  • EX seconds -- Set the specified expire time, in seconds.
  • PX milliseconds -- Set the specified expire time, in milliseconds.
  • EXAT timestamp-seconds -- Set the specified Unix time at which the key will expire, in seconds.
  • PXAT timestamp-milliseconds -- Set the specified Unix time at which the key will expire, in milliseconds.
  • PERSIST -- Remove the time to live associated with the key.

*Return value

Bulk string reply: the value of key, or nil when key does not exist.
