The server runs indefinitely, but can be stopped by a keyboard interrrupt.


  • executor: The executor to be hosted by the server.
  • num_threads: The number of network threads to use for handling gRPC calls.
  • port: The port to listen on (for gRPC), must be a non-zero integer.
  • credentials: The optional credentials to use for the secure connection if any, or None if the server should open an insecure port. If specified, must be a valid ServerCredentials object that can be accepted by the gRPC server's add_secure_port().
  • options: The optional list of server options, each in the (key, value) format accepted by the grpc.server() constructor.


  • ValueError: If num_threads or port are invalid.
