public interface ReactiveResultSet extends org.reactivestreams.Publisher<ReactiveRow>, ReactiveQueryMetadata
Publisher of ReactiveRows returned by a ReactiveSession.
By default, all implementations returned by the driver are cold, unicast, single-subscriber only publishers. In other words, they do not support multiple subscriptions; consider caching the results produced by such publishers if you need to consume them by more than one downstream subscriber.
Also, note that reactive result sets may emit items to their subscribers on an internal driver
IO thread. Subscriber implementors are encouraged to abide by Reactive Streams
Specification rule 2.2 and avoid performing heavy computations or blocking calls inside
onNext calls, as doing so could slow down
the driver and impact performance. Instead, they should asynchronously dispatch received signals
to their processing logic.
This interface exists mainly to expose useful information about request execution and query metadata. This is particularly convenient for queries that do not return rows; for queries that do return rows, it is also possible, and oftentimes easier, to access that same information at row level.
