This API provides two methods for retrieving paginated results:
Method 1: Set the MaxResults parameter to specify the number of results per page. To retrieve the next page, pass the NextToken value returned from the previous call to the DescribeDBInstances API. The NextToken value is the pagination token.
For your initial paginated query, you only need to set the MaxResults parameter. The API returns the first page of results and a NextToken value.
Method 2: Use PageSize to set the number of results per page and PageNumber to specify the page to retrieve.
You can use only one of these methods per request. For large result sets, Method 1 provides better query performance.
