final case class GenericRecordParseIO[T](path: String, parseFn: (GenericRecord) => T)(implicit evidence$2: Coder[T]) extends ScioIO[T] with Product with Serializable

Given a parseFn, read GenericRecord and apply a function mapping => T before producing output. This IO applies the function at the time of de-serializing Avro GenericRecords.

This IO doesn't define write, and should not be used to write Avro GenericRecords.

  19. def tap(read: ReadP): Tap[Nothing]

    Write options also return a ClosedTap.

    Write options also return a ClosedTap. Once the job completes you can open the Tap. 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.

  20. val tapT: Aux[T, Nothing]

    Output tap type.

    Output tap type.

    This _must_ be a stable value (a val, not a def) in every implementation, otherwise the return type of write cannot be inferred.
