Github user gyfora commented on the pull request: https://github.com/apache/flink/pull/906#issuecomment-121548970 If we can still have the records without timestamps that would be good. But this should be automatic. Regarding monitoring, this seems to be an overkill for that purpose. We could "sample" the stream and attach timestamps there and that wouldn't be a large overhead.
