GETDEL reads the string at key and deletes the key in the same step, so no other client can read the value in between. Use it to consume one-time values such as tokens.

Return value

Section titled “Return value”
Case RESP2 RESP3
The key held a string Bulk string: the value Bulk string
The key does not exist Nil bulk string Null

GETDEL replies with a WRONGTYPE error, and deletes nothing, when the key holds a value that is not a string.

Examples

Section titled “Examples”
