name

The user-specified Cloud Dataflow job name. Only one Job with a given name can exist in a project within one region at any given time. Jobs in different regions can have the same name. If a caller attempts to create a Job with the same name as an already-existing Job, the attempt returns the existing Job. The name must match the regular expression [a-z]([-a-z0-9]{0,1022}[a-z0-9])?
