/**
* Container for the parameters to the {@link com.amazonaws.services.kinesis.AmazonKinesis#describeStream(DescribeStreamRequest) DescribeStream operation}.
*
* Describes the specified stream.
*
*
* The information about the stream includes its current status, its
* Amazon Resource Name (ARN), and an array of shard objects. For each
* shard object, there is information about the hash key and sequence
* number ranges that the shard spans, and the IDs of any earlier shards
* that played in a role in creating the shard. A sequence number is the
* identifier associated with every record ingested in the Amazon Kinesis
* stream. The sequence number is assigned when a record is put into the
* stream.
*
*
* You can limit the number of returned shards using the
* Limit parameter. The number of shards in a stream may be
* too large to return from a single call to DescribeStream
* .
* You can detect this by using the HasMoreShards
* flag in the returned output. HasMoreShards is set to
* true when there is more data available.
*
*
* DescribeStream is a paginated operation. If there are
* more shards available, you can request them using the shard ID of the
* last shard returned. Specify this ID in the
* ExclusiveStartShardId parameter in a subsequent request
* to DescribeStream .
*
*
*
* DescribeStream has a limit of 10 transactions per second
* per account.
