Work Description: wtanaka commented on issue #7736: [BEAM-5638] Exception
handling for Java MapElements and FlatMapElements
URL: https://github.com/apache/beam/pull/7736#issuecomment-464210191
The main advantage of an Either<BadT, GoodT> that I'm picturing is compile
time type safety for hooking up ptransforms and pcollections. With the
pcollection tuple class, I couldn't figure out a way to indicate at compile
time what the types of its constituent pcollections are. This then leads to
having difficulty coming up with a good statically type checked pattern for
creating reusable ptransform classes that have both a success outpit and a dead
letter output.
