public final class Step extends GeneratedMessageV3 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. 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.
