Vedis Built-in Commands - Key/Value.

Command

APPEND key value

Description

If key already exists and is a string, this command appends the value at the end of the string. If key does not exist it is created and set as an empty string, so APPEND will be similar to SET in this special case.

Return value

Integer: The length of the string after the append operation.

Example
