As for the question if it was easy to use side outputs instead of split/select. Personally I found it rather straightforward. In the IterateExample I even find the code much simpler, as the splitting is coupled within the mapper which looks more natural to me. There are two issues I found that could've been a bit easier: 1. It would be nice if we could have side outputs e.g. from RichMapFunction. I had to replace `MapFunction` with `ProcessFunction` 2. ~~I also found a comment in the `OutputTag` a bit misleading: `It is also not possible to use generic type variables with OutputTags, such as 'Tuple2<A, B>'` It is actually possible to do, you just need to create the OutputTag as an anonymous class. I will change the comment in the exception.~~ I misunderstood the message. It is actually correct. I missed the **generic** bit. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
