ASF GitHub Bot commented on FLINK-2030: --------------------------------------- Github user chiwanpark commented on the pull request: https://github.com/apache/flink/pull/861#issuecomment-137376194 Hi, I just reviewed the updated PR. Sorry for late. Your implementation is nice. It seems acting like I expected. But I have to check the following: I'm concerned about changing `Histogram` class. It causes API breaking. I'm not sure that this breaking is necessary. Reverting the changes of `Histogram` would be better. Because there are many differences between `ContinuousHistogram` and `DiscreteHistogram`, we don't need to create base class for them. I'm sorry about consuming time to merge this PR. It seems almost arrived the goal.
