def and(condition: (Table) ⇒ clauses.WhereClause.Condition)(implicit ev: =:=[Chain, Chainned]): DeleteQuery[Table, Record, Limit, Order, Status, Chainned, PS]

And clauses require overriding for count queries for the same purpose.
And clauses require overriding for count queries for the same purpose. Without this override, the CQL query executed to fetch the count would still have a "LIMIT 1".
condition
The Query condition to execute, based on index operators.
returns
A SelectCountWhere.

def execute()(implicit session: Session, keySpace: KeySpace): Future[ResultSet]

Default asynchronous query execution method based on Twitter Future API.
Default asynchronous query execution method based on Twitter Future API. This will convert the underlying call to Cassandra done with Google Guava ListenableFuture to a consumable Twitter Future that will be completed once the operation is completed on the database end.
Unlike Scala Futures, Twitter Futures and operations on them do not require an implicit context. Instead, the context propagates from one future to another inside a flatMap chain which means all operations(map, flatMap) that originate on a Twitter Future obtained as the result of a database call will execute inside com.websudos.phantom.Manager.executor.
session
The implicit session provided by a com.websudos.phantom.connectors.Connector.
keySpace
The implicit keySpace definition provided by a com.websudos.phantom.connectors.Connector.

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.websudos.phantom.Manager.scalaExecutor and it is recommended to use com.websudos.phantom.dsl.context for operations that chain database calls.
