- The ExecuteGraph method is removed from the service interface. - Client::Execute calls Compile + Execute instead of ExecuteGraph. The existing users of this method is not affected. - The Compile compiles the graph into an executable. Since the argument shapes will affect how the graph is compiled, the Client::Compile has an argument `argument_shapes`, which must be the same as the shapes of the arguments being used in the Execute method. - The service cache the exectuables.
