public class ThreadPoolExecutorPlus extends ThreadPoolExecutorBase implements ExecutorPlus
ThreadPoolExecutorBase
and ThreadPoolExecutorBuilder. Most Cassandra executors should use or extend this.
This class' addition is to abstract the semantics of task encapsulation to handle
exceptions and ExecutorLocals.
