/**
* Container for the parameters to the {@link com.amazonaws.services.kinesis.AmazonKinesis#createStream(CreateStreamRequest) CreateStream operation}.
*
* This operation adds a new Amazon Kinesis stream to your AWS account. 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 write transactions 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.
*
*
* You receive a LimitExceededException when making a
* CreateStream request 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.
*
*
*
* Note: The default limit for an AWS account is 10 shards per
* stream. If you need to create a stream with more than 10 shards,
* contact AWS Support
* to increase the limit on your account.
*
*
* You can use the DescribeStream operation to check the
* stream status, which is returned in StreamStatus .
*
*
* CreateStream has a limit of 5 transactions per second
* per account.
