.Write options also return a

. Once the job completes you can open theTap
. Tap abstracts away the logic of reading the dataset directly as an Iterator[T] or re-opening it in another ScioContext. The Future is complete once the job finishes. This can be used to do light weight pipeline orchestration e.g. WordCountOrchestration.scala. - val tapT: Aux[T, T]
Output tap type.
