watch

Publisher<HealthCheckResponse> watch(GrpcServiceContext ctx,
 HealthCheckRequest request)

  Performs a watch for the serving status of the requested service.
  The server will immediately send back a message indicating the current
  serving status.  It will then subsequently send a new message whenever
  the service's serving status changes.

  If the requested service is unknown when the call is received, the
  server will send a message setting the serving status to
  SERVICE_UNKNOWN but will *not* terminate the call.  If at some
  future point, the serving status of the service becomes known, the
  server will send a new message with the service's serving status.

  If the call terminates with status UNIMPLEMENTED, then clients
  should assume this method is not supported and should not retry the
  call.  If the call terminates with any other status (including OK),
  clients should retry the call with appropriate exponential backoff.
 

Parameters:

ctx - context associated with this service and request.

request - the request from the client.

Returns:

used to write a stream of type HealthCheckResponse to the client.
