public interface ContinuousAsyncResultSet extends AsyncPagingIterable<Row,ContinuousAsyncResultSet>
DSE replies to a continuous query with a stream of response frames. There is one instance of this class for each frame.

Cancels the continuous query.
Returns information about the execution of this page of results.

Note: because the driver does not support query traces for continuous queries,
ExecutionInfo.getTracingId() will always be
