listDatabases method

Future<ListDatabasesResponse> listDatabases({ required String database, String? clusterIdentifier, String? dbUser, int? maxResults, String? nextToken, String? secretArn, String? workgroupName, })

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:

• Secrets Manager - when connecting to a cluster, provide the secret-arn of a secret stored in Secrets Manager which has username and password. The specified secret contains credentials to connect to the database you specify. When you are connecting to a cluster, you also supply the database name, If you provide a cluster identifier (dbClusterIdentifier), it must match the cluster identifier stored in the secret. When you are connecting to a serverless workgroup, you also supply the database name.
• Temporary credentials - when connecting to your data warehouse, choose one of the following options:
  • 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, arn:iam::123456789012:user:foo has the database user name IAM:foo. Also, permission to call the redshift-serverless:GetCredentials operation is required.
  • 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, arn:iam::123456789012:user:foo has the database user name IAM:foo. Also, permission to call the redshift:GetClusterCredentialsWithIAM operation is required.
  • 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 redshift:GetClusterCredentials operation is required.

May throw DatabaseConnectionException. May throw InternalServerException. May throw QueryTimeoutException. May throw ResourceNotFoundException. May throw ValidationException.

Parameter database : The name of the database. This parameter is required when authenticating using either Secrets Manager or temporary credentials.

Parameter clusterIdentifier : The cluster identifier. This parameter is required when connecting to a cluster and authenticating using either Secrets Manager or temporary credentials.

Parameter dbUser : The database user name. This parameter is required when connecting to a cluster as a database user and authenticating using temporary credentials.

Parameter maxResults : The maximum number of databases to return in the response. If more databases exist than fit in one response, then NextToken is returned to page through the results.

Parameter nextToken : A value that indicates the starting point for the next set of response records in a subsequent request. If a value is returned in a response, you can retrieve the next set of records by providing this returned NextToken value in the next NextToken parameter and retrying the command. If the NextToken field is empty, all response records have been retrieved for the request.

Parameter secretArn : The name or ARN of the secret that enables access to the database. This parameter is required when authenticating using Secrets Manager.

Parameter workgroupName : The serverless workgroup name or Amazon Resource Name (ARN). This parameter is required when connecting to a serverless workgroup and authenticating using either Secrets Manager or temporary credentials.
