// 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 (https://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 Amazon Web Services Support (https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html)
// . You can use DescribeStreamSummary to check the stream status, which is
// returned in StreamStatus . CreateStream has a limit of five transactions per
// second per account.
