Github user aljoscha commented on the issue: https://github.com/apache/flink/pull/2729 I realise I'm a bit late but I think we should not add a config that allows Scala Object functions. The only case where this makes sense if you have a pipeline with parallelism 1. Allowing users to override can only lead to problems in the future. What do you think?
