    • generateUid

      Optional<String> generateUid(String name)
      Generates a new unique identifier for a Transformation/DataStream operator. The name must be unique within the provider implementation. The framework will make sure that the name is unique for the entire topology.

      This method returns empty if an identifier cannot be generated, i.e., because the job is in batch mode, or UIDs cannot be guaranteed to be unique.
