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-461994350
- In my use cases, wanting to keep the input element seems to be a pretty
common case -- at the very least to be able to help debug what was bad about it.
- One thing that I have found myself wishing for frequently is for
exceptions to go into an `Either`, i.e. for the return value of the
`MapElements` to be a: `PCollection<Either<ExceptionT, SuccessT>>` Having a
standard "blessed" way to do this would be very helpful. I've been meaning to
try to contribute something like this but haven't been able to make the time
yet.
