def future()(implicit session: Session, ec: ExecutionContextExecutor): Future[ResultSet]

Default asynchronous query execution method.
Default asynchronous query execution method. This will convert the underlying call to Cassandra done with Google Guava ListenableFuture to a consumable Scala Future that will be completed once the operation is completed on the database end.
The execution context of the transformation is provided by phantom via com.outworkers.phantom.Manager.scalaExecutor and it is recommended to use com.outworkers.phantom.dsl.context for operations that chain database calls.
session

An asynchronous Scala future wrapping the Datastax result set.

Returns a parsed sequence of [R]ows.
Returns a parsed sequence of [R]ows. This will only fetch the amount of records defined in the fetchSize setting. It will allow pagination of the inner result set as a scala.collection.immutable.List.
It will greedy evaluate the records inside a single fetch size batch as it returns a list as opposed to an iterator. For a non greedy variant of the size method use iterator().

Returns a parsed iterator of [R]ows lazily evaluated. This will respect the fetch size setting of a query, meaning you will need to provide a paging state to fetch records beyond the regular fetch size.
