+ * Service definition for apache Pulsar Client ControllerService
+ * responsible for maintaining a pool of @PulsarProducer and
+ * @PulsarConsumer objects.
+ *
+ * Since both of these objects can be reused, in a manner similar
+ * to database connections, and the cost to create these objects is
+ * relatively high. The PulsarClientPool keeps these objects in pools
+ * for re-use.
