// CreateStreamRequest returns a request value for making API operation for
// Amazon Kinesis.
//
// Creates a Kinesis data stream. A stream captures and transports data records
// that are continuously emitted from different data sources or producers. Scale-out
// within a stream is explicitly supported by means of shards, which are uniquely
// identified groups of data records in a stream.
//
// You specify and control the number of shards that a stream is composed of.
// Each shard can support reads up to five transactions per second, up to a
// maximum data read total of 2 MB per second. Each shard can support writes
// up to 1,000 records per second, up to a maximum data write total of 1 MB
// per second. If the amount of data input increases or decreases, you can add
// or remove shards.
//
// The stream name identifies the stream. The name is scoped to the AWS account
// used by the application. It is also scoped by AWS Region. That is, two streams
// in two different accounts can have the same name, and two streams in the
// same account, but in two different Regions, can have the same name.
//
// CreateStream is an asynchronous operation. Upon receiving a CreateStream
// request, Kinesis Data Streams immediately returns and sets the stream status
// to CREATING. After the stream is created, Kinesis Data Streams sets the stream
// status to ACTIVE. You should perform read and write operations only on an
// ACTIVE stream.
//
// You receive a LimitExceededException when making a CreateStream request when
// you try to do one of the following:
//
// * Have more than five streams in the CREATING state at any point in time.
//
// * Create more shards than are authorized for your account.
//
// For the default shard limit for an AWS account, see Amazon Kinesis Data Streams
// Limits (http://docs.aws.amazon.com/kinesis/latest/dev/service-sizes-and-limits.html)
// in the Amazon Kinesis Data Streams Developer Guide. To increase this limit,
// contact AWS Support (http://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html).
//
// You can use DescribeStream to check the stream status, which is returned
// in StreamStatus.
//
// CreateStream has a limit of five transactions per second per account.
//
// // Example sending a request using CreateStreamRequest.
