Managing Resource Tags Using the Console
The following is an example of the Manage Tags window for an Amazon Redshift resource, such as a
cluster or a parameter group.
You use the Add Tags section to add key pairs to an Amazon Redshift resource.When you begin entering
a key pair in the Add Tags section, a new row will appear so that you can add another key pair, and so
on. For more information about allowed characters for keys and values, see Tagging Requirements (p.241).
If you decide that you don't want to add a particular tag to the resource, you can remove it from the Add
Tags section by clicking the X in the row. Once you have specified the key pairs that you want to add,
you apply the changes so that they are associated with the resource.
