// Creates a Amazon Kinesis stream. A stream captures and transports data records
// that are continuously emitted from different data sources or producers. Scale-out
// within an Amazon Kinesis stream is explicitly supported by means of shards,
// which are uniquely identified groups of data records in an Amazon Kinesis
// stream.
//
// You specify and control the number of shards that a stream is composed of.
// Each open shard can support up to 5 read transactions per second, up to a
// maximum total of 2 MB of data read per second. Each shard can support up
// to 1000 records written per second, up to a maximum total of 1 MB data written
// per second. You can add shards to a stream if the amount of data input increases
// and you can remove shards if the amount of data input decreases.
//
// The stream name identifies the stream. The name is scoped to the AWS account
// used by the application. It is also scoped by 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, Amazon Kinesis immediately returns and sets the stream status to
// CREATING. After the stream is created, Amazon Kinesis sets the stream status
// to ACTIVE. You should perform read and write operations only on an ACTIVE
// stream.
//

// if 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 Limits (http://docs.aws.amazon.com/kinesis/latest/dev/service-sizes-and-limits.html).
// If you need to increase this limit, contact AWS Support (http://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html)

// in StreamStatus.

// of the shard that the iterator points to, GetRecords returns an empty list.
// Note that it might take multiple calls to get to a portion of the shard that
// contains records.
//
// You can scale by provisioning multiple shards. Your application should have
// one thread per shard, each reading continuously from its stream. To read
// from a stream continually, call GetRecords in a loop. Use GetShardIterator
// to get the shard iterator to specify in the first GetRecords call. GetRecords
// returns a new shard iterator in NextShardIterator. Specify the shard iterator
// returned in NextShardIterator in subsequent calls to GetRecords. Note that
// if the shard has been closed, the shard iterator can't return more data and
// GetRecords returns null in NextShardIterator. You can terminate the loop
// when the shard is closed, or when the shard iterator reaches the record with
// the sequence number or other attribute that marks it as the last record to
// process.
//
// Each data record can be up to 50 KB in size, and each shard can read up
// to 2 MB per second. You can ensure that your calls don't exceed the maximum
// supported size or throughput by using the Limit parameter to specify the
// maximum number of records that GetRecords can return. Consider your average
// record size when determining this limit. For example, if your average record
// size is 40 KB, you can limit the data returned to about 1 MB per call by
// specifying 25 as the limit.
//
// The size of the data returned by GetRecords will vary depending on the utilization
// of the shard. The maximum size of data that GetRecords can return is 10 MB.
// If a call returns this amount of data, subsequent calls made within the next
// 5 seconds throw ProvisionedThroughputExceededException. If there is insufficient
// provisioned throughput on the shard, subsequent calls made within the next

// won't return any data when it throws an exception. For this reason, we recommend
// that you wait one second between calls to GetRecords; however, it's possible
// that the application will get exceptions for longer than 1 second.
