Abstract Value Members
- abstract def discover(in: ProxyInfo): Future[Spec]
Discover what components the user service wishes to serve.
- abstract def healthCheck(in: Empty): Future[HealthCheckResponse]
Health check for the user service to detect if it stops, crashes or becomes unresponsive and the proxy needs to restart it.
Health check for the user service to detect if it stops, crashes or becomes unresponsive and the proxy needs to restart it. The SDK should respond in a timely fashion if healthy or fail the request if not.
- abstract def proxyTerminated(in: Empty): Future[Empty]
When the Kalix proxy is shutting down it sends this signal at the end of the shutdown process.
When the Kalix proxy is shutting down it sends this signal at the end of the shutdown process. The user service container should preferably delay its own shutdown until the proxy has terminated to be able to drain requests in flight from the proxy.
- abstract def reportError(in: UserFunctionError): Future[Empty]
Report an error back to the user service.
Report an error back to the user service. This will only be invoked to tell the user service that it has done something wrong, eg, violated the protocol, tried to use a component type that isn't supported, or attempted to forward to a component that doesn't exist, etc. These messages should be logged clearly for debugging purposes.
