Using a Connection Link
Creation and use of a connection link is dependent on the permissions granted to a user. The following are the permissions that can be granted to users:
CREATE LINK: A user with theCREATE LINKpermission can create a connection link and only that user will know the connection details.SHOW LINK: A user with theSHOW LINKpermission can view and use all connection links that exist in a SingleStore DB database.DROP LINK: A user with theDROP LINKpermission can remove a connection link that exists in a SingleStore DB database.
Note: The listed permissions can be cluster or database scoped. For example, you can grant the CREATE LINK permission on *.* (cluster scoped) and database.* (database scoped) but not database.table. See the GRANT topic for more details.
