            #     Required. Specifies the path, relative to `Cluster`, of
            #     the field to update. For example, to change the number of workers
            #     in a cluster to 5, the `update_mask` parameter would be
            #     specified as `config.worker_config.num_instances`,
            #     and the `PATCH` request body would specify the new value, as follows:

            #         }
            #     Similarly, to change the number of preemptible workers in a cluster to 5,
            #     the `update_mask` parameter would be
            #     `config.secondary_worker_config.num_instances`, and the `PATCH` request
            #     body would be set as follows:
