The WebSocket feed type consumes messages from an externally accessible WebSocket server. The WebSocket protocol enables two-way low-latency communication between a client and server. It accomplishes this by establishing persistent socket connections between a server and client where the server sends data to connected clients. In this case, ArcGIS Velocity acts as the WebSocket client.
Example
- Updated sensor values are broadcast from a WebSocket server.
Usage notes
- The WebSocket server must be externally accessible on the Internet.
After configuring feed connection properties, see Configure input data to learn how to define the schema and the key properties.
