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) // .
