// 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 can create your data stream using either on-demand or provisioned capacity
// mode. Data streams with an on-demand mode require no capacity planning and
// automatically scale to handle gigabytes of write and read throughput per minute.
// With the on-demand mode, Kinesis Data Streams automatically manages the shards
// in order to provide the necessary throughput. For the data streams with a
// provisioned mode, you must specify the number of shards for the data stream.
// Each shard can support reads up to five transactions per second, up to a maximum
// data read total of 2 MiB per second. Each shard can support writes up to 1,000
// records per second, up to a maximum data write total of 1 MiB 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 Amazon Web
// Services account used by the application. It is also scoped by Amazon Web
// Services 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 Amazon Web Services account, see [Amazon Kinesis Data Streams Limits] in the
// Amazon Kinesis Data Streams Developer Guide. To increase this limit, [contact Amazon Web Services Support].
//
// You can use DescribeStreamSummary to check the stream status, which is returned in StreamStatus .
//
// CreateStreamhas a limit of five transactions per second per account.
