-- second request will be ignored and the first
-- google.longrunning.Operation created and stored in the backend is
-- returned.It is recommended to always set this value to a UUID
-- (https:\/\/en.wikipedia.org\/wiki\/Universally_unique_identifier).The id

-- | 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: { \"config\":{ \"workerConfig\":{
-- \"numInstances\":\"5\" } } } 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: { \"config\":{ \"secondaryWorkerConfig\":{
-- \"numInstances\":\"5\" } } } __Note:__ Currently, only the following
-- fields can be updated:
