2020/09/09 - Redshift Data API Service - 9 new api methods
Changes The Amazon Redshift Data API is generally available. This release enables querying Amazon Redshift data and listing various database objects.
List the tables in a database. If neither SchemaPattern nor TablePattern are specified, then all tables in the database are returned. A token is returned to page through the table list. Depending on the authorization method, use one of the following combinations of request parameters:
AWS Secrets Manager - specify the Amazon Resource Name (ARN) of the secret and the cluster identifier that matches the cluster in the secret.
Temporary credentials - specify the cluster identifier, the database name, and the database user name. Permission to call the redshift:GetClusterCredentials operation is required to use this method.

string
[REQUIRED]
The cluster identifier. This parameter is required when authenticating using either AWS Secrets Manager or temporary credentials.
string
[REQUIRED]
The name of the database. This parameter is required when authenticating using temporary credentials.
string
The database user name. This parameter is required when authenticating using temporary credentials.
integer
The maximum number of tables to return in the response. If more tables exist than fit in one response, then NextToken is returned to page through the results.
string
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.
string
A pattern to filter results by schema name. Within a schema pattern, "%" means match any substring of 0 or more characters and "_" means match any one character. Only schema name entries matching the search pattern are returned. If SchemaPattern is not specified, then all tables that match TablePattern are returned. If neither SchemaPattern or TablePattern are specified, then all tables are returned.
string
The name or ARN of the secret that enables access to the database. This parameter is required when authenticating using AWS Secrets Manager.

A pattern to filter results by table name. Within a table pattern, "%" means match any substring of 0 or more characters and "_" means match any one character. Only table name entries matching the search pattern are returned. If TablePattern is not specified, then all tables that match SchemaPattern are returned.
