// the specified streaming source (Amazon Kinesis stream or Amazon Kinesis Firehose
// delivery stream) or S3 object. In the response, the operation returns the
// inferred schema and also the sample records that the operation used to infer the
// schema. You can use the inferred schema when configuring a streaming source for
