| <h2>ParDo</h2> |
| <p> |
| ParDo is a Beam transform for generic parallel processing. The ParDo processing paradigm is |
| similar to the “Map” phase of a Map/Shuffle/Reduce-style algorithm: a ParDo transform considers |
| each element in the input PCollection, performs some processing function (your user code) on |
| that element, and emits zero, one, or multiple elements to an output PCollection. |
| </p> |
| <p> |
| <b>Kata:</b> Please write a simple ParDo that maps the input element by multiplying it by 10. |
