Till Rohrmann commented on FLINK-16478:
---------------------------------------
Thanks for updating the design document [~dixingx...@yeah.net]. I will take
another look after the feature freeze for the {{1.11}} release has passed.
Some quick comments:
1. I agree that a timer feature would be nice but I believe that this is not
strictly necessary. The user can change the logging level once he no longer
needs the previous log level. I think this is simpler to achieve and would
narrow down the scope even further.
2. Supporting log4j2 and logback sounds good. If Flink runs with a not
supported logging framework, then it would be good to report back with a
meaningful error message in case that the user tries to adjust the logging
level.
