        { # Defines a particular step within a Cloud Dataflow job.
            #
            # A job consists of multiple steps, each of which performs some
            # specific operation as part of the overall job.  Data is typically
            # passed from one step to another as part of the job.
            #
            # Here&#x27;s an example of a sequence of steps which together implement a
            # Map-Reduce job:
            #
            #   * Read a collection of data from some source, parsing the
            #     collection&#x27;s elements.
            #
            #   * Validate the elements.
            #
            #   * Apply a user-defined function to map each element to some value
            #     and extract an element-specific key value.
            #
            #   * Group elements with the same key into a single element with
            #     that key, transforming a multiply-keyed collection into a
            #     uniquely-keyed collection.
            #
            #   * Write the elements out to some data sink.
            #

            # types of jobs, not just Map-Reduce.
