+   - The client first sends a GetEndpoints request with the None policy to retrieve the endpoint list

 In this mode, IoTDB's stream processing engine sends data change events to the OPC UA Server through an OPC UA Sink. These events are published to the server's message queue and managed through Event Nodes. Other OPC UA Clients can subscribe to these Event Nodes to receive notifications upon data changes.

 #### 2.2.2 Pub/Sub Mode
 
 In this mode, IoTDB's stream processing engine sends data change events to the OPC UA Server (Server) via OPC UA Sink. These events are published to the server's message queue and managed via Event Nodes. Other OPC UA clients (Clients) can subscribe to these Event Nodes to receive notifications when data changes.
