User Advantages

  1. Referring to a connection link in a command is more secure than specifying the connection details directly in the command. Users need the CREATE LINK permission to create connection links, and only those users need to know the connection details.

  2. Commands such as BACKUP,RESTORE, CREATE PIPELINE, and SELECT support connection links. Users can run these commands without specifying the connection details. However, the user needs the SHOW LINK permission to use a connection link.
