Scalability Tab

This toggle specifies if the Robot service subscribes to Orchestrator's SignalR channels or not. By default, this setting is enabled, and all available channels are selected:

When all transport channels are enabled, the best available transport is automatically selected, in the following priority order: WebSocket > Server-Sent Events > Long Polling. If the first protocol is not available for any reason, the next in line (if enabled) is used to facilitate the communication between Orchestrator and Robot.

When selected, enables the WebSocket transport protocol to be used to connect the Robot to Orchestrator's SignalR channels. This is the highest protocol used in the order of priority due to its performance and support for simultaneous communication in both directions - from the Robot service to Orchestrator and vice versa.

If the SignalR (Robots) feature is not enabled, WebSocket becomes the only available transport protocol.

When selected, enables the Server-Sent Events (SSE) push technology to be used to connect the Robot to Orchestrator's SignalR channels. This is the first backup in case WebSockets is not available for any reason.

This option cannot be used if the SignalR (Robots) feature is not enabled.
