@Generated public final class Step extends com.google.protobuf.GeneratedMessage implements StepOrBuilder
 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.

 **Note:** The properties of this object are not stable and might change.

 Here'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'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.

 Note that the Cloud Dataflow service may be used to run many different
 types of jobs, not just Map-Reduce.
