 * <p>List the databases in a cluster. A token is returned to page through the database list. Depending on the authorization method, use one of the following combinations of request parameters: </p> <ul> <li> <p>Secrets Manager - when connecting to a cluster, provide the <code>secret-arn</code> of a secret stored in Secrets Manager which has <code>username</code> and <code>password</code>. The specified secret contains credentials to connect to the <code>database</code> you specify. When you are connecting to a cluster, you also supply the database name, If you provide a cluster identifier (<code>dbClusterIdentifier</code>), it must match the cluster identifier stored in the secret. When you are connecting to a serverless workgroup, you also supply the database name.</p> </li> <li> <p>Temporary credentials - when connecting to your data warehouse, choose one of the following options:</p> <ul> <li> <p>When connecting to a serverless workgroup, specify the workgroup name and database name. The database user name is derived from the IAM identity. For example, <code>arn:iam::123456789012:user:foo</code> has the database user name <code>IAM:foo</code>. Also, permission to call the <code>redshift-serverless:GetCredentials</code> operation is required.</p> </li> <li> <p>When connecting to a cluster as an IAM identity, specify the cluster identifier and the database name. The database user name is derived from the IAM identity. For example, <code>arn:iam::123456789012:user:foo</code> has the database user name <code>IAM:foo</code>. Also, permission to call the <code>redshift:GetClusterCredentialsWithIAM</code> operation is required.</p> </li> <li> <p>When connecting to a cluster as a database user, specify the cluster identifier, the database name, and the database user name. Also, permission to call the <code>redshift:GetClusterCredentials</code> operation is required.</p> </li> </ul> </li> </ul> <p>For more information about the Amazon Redshift Data API and CLI usage examples, see <a href="https://docs.aws.amazon.com/redshift/latest/mgmt/data-api.html">Using the Amazon Redshift Data API</a> in the <i>Amazon Redshift Management Guide</i>. </p>
