## 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.

Use ParDo with DoFn.
Refer to the Beam Programming Guide "ParDo" section for more information.
