IExecutor Threading
Executor threading is straight forward. When a task is received to be executed on Executor E, then E will have its
own ThreadPoolExecutor instance and the work is put on the work queue of this executor. Thus, Executors are fully isolated, but still share the same underlying hardware; most importantly the CPUs.
You can configure the IExecutor using the ExecutorConfig (programmatic configuration) or using <executor> (declarative configuration).
