def future(modifyStatement: Modifier)(implicit session: Session, executor: ExecutionContextExecutor): Future[ResultSet]

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.
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.
modifyStatement
The function allowing to modify underlying Statement
session
The implicit session provided by a com.outworkers.phantom.connectors.Connector.
executor
The implicit Scala executor.
returns
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().

def iterator(modifier: Modifier)(implicit session: Session, ec: ExecutionContextExecutor): Future[IteratorResult[R]]

Returns a parsed iterator of [R]ows lazily evaluated.
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.
session

returns
A Scala future wrapping scala iterator of mapped results.

Returns a parsed sequence of [R]ows but paginates the results using paging state. This will not consume or return the entire set of available results, it will instead return an amount of records equal to the fetch size setting.
