// parameter, Kinesis Data Streams uses the default limit, which is currently 100.
// You can detect if there are more streams available to list by using the
// HasMoreStreams flag from the returned output. If there are more streams
// available, you can request more streams by using the name of the last stream
// returned by the ListStreams request in the ExclusiveStartStreamName parameter
// in a subsequent request to ListStreams . The group of stream names returned by
// the subsequent request is then added to the list. You can continue this process
// until all the stream names have been collected in the list. ListStreams has a
// limit of five transactions per second per account.
