    FunctionImplementationType implementationType = ((RemoteScalarFunctionImplementation) functionImplementation).getImplementationType();
    checkState(sqlFunctionExecutor.getImplementationType().equals(implementationType), format("%s SQL function executor is not setup", implementationType));
    return sqlFunctionExecutor.executeFunction(source, (RemoteScalarFunctionImplementation) functionImplementation, input, channels, argumentTypes, returnType);
