docs: <p>
  Creates a <code>DataSource</code> object from an <a href="http://aws.amazon.com/rds/"> Amazon Relational Database
  Service</a> (Amazon RDS). A <code>DataSource</code> references data that can be used to perform
  <code>CreateMLModel</code>, <code>CreateEvaluation</code>, or <code>CreateBatchPrediction</code> operations.
  </p>
  <p>
  <code>CreateDataSourceFromRDS</code> is an asynchronous operation. In response to
  <code>CreateDataSourceFromRDS</code>, Amazon Machine Learning (Amazon ML) immediately returns and sets the
  <code>DataSource</code> status to <code>PENDING</code>. After the <code>DataSource</code> is created and ready
  for use, Amazon ML sets the <code>Status</code> parameter to <code>COMPLETED</code>. <code>DataSource</code> in
  the <code>COMPLETED</code> or <code>PENDING</code> state can be used only to perform
  <code>&gt;CreateMLModel</code>&gt;, <code>CreateEvaluation</code>, or <code>CreateBatchPrediction</code>
  operations.
  </p>
  <p>
  If Amazon ML cannot accept the input source, it sets the <code>Status</code> parameter to <code>FAILED</code> and
  includes an error message in the <code>Message</code> attribute of the <code>GetDataSource</code> operation
  response.

  @param createDataSourceFromRDSRequest
  @return Result of the CreateDataSourceFromRDS operation returned by the service.
  @throws InvalidInputException
  An error on the client occurred. Typically, the cause is an invalid input value.
  @throws InternalServerException
  An error on the server occurred when trying to process a request.
  @throws IdempotentParameterMismatchException
  A second request to use or change an object was not allowed. This can result from retrying a request
  using a parameter that was not present in the original request.
