# ParDo

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.

**Kata:** Please write a simple ParDo that maps the input element by multiplying it by 10.
