// Amazon DynamoDB Streams provides API actions for accessing streams and processing
// stream records. To learn more about application development with Streams,
// see Capturing Table Activity with DynamoDB Streams (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.html)
// in the Amazon DynamoDB Developer Guide.
//
// The following are short descriptions of each low-level DynamoDB Streams action:
//
//    * DescribeStream - Returns detailed information about a particular stream.
//
//    * GetRecords - Retrieves the stream records from within a shard.
//
//    * GetShardIterator - Returns information on how to retrieve the streams
//    record from a shard with a given shard ID.
//
//    * ListStreams - Returns a list of all the streams associated with the
//    current AWS account and endpoint.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
