Github user StephanEwen commented on the pull request: https://github.com/apache/flink/pull/1966#issuecomment-220395032 I think for now, we should add a `@Deprecated` annotation to the `Histogram` and its related method on `RuntimeContext` and mention in the comment that we encourage the `LongHistogram` instead. On a major release, we should go through all deprecated parts and remove them. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

Github user mbode commented on the pull request: https://github.com/apache/flink/pull/1966#issuecomment-220277425 Hi Stephan, sounds good. 1. I wanted to avoid too much duplication, but I see your point. 2. Ok, throwing a new exception breaks the API. So should I just mark `Histogram` as deprecated? I guess the proper way would be to make Histogram generic, enabling users to instantiate Histogram. Again, this breaks the API, so we would have to wait for the next major release â what is the process for cases like that? --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

Github user StephanEwen commented on the pull request: https://github.com/apache/flink/pull/1966#issuecomment-220275206 I like the addition. Two things, however, that I am not sure about: 1. The `Histogram` uses a `LongHistogram` internally, which results in a lot of wrapping and converting. Each accumulator report (each heartbeat) needs to do the conversion. I think the Histogram should rather hold the proper (int, int) map directly. 2. I am skeptical about failing hard in the Histogram on an integer overflow. These kind of hard failures in utility types are always tricky. A program causing an overflow will result in a non-recoverable failure (it will always overflow again). For streaming programs, that is not a nice property. I would actually rather try to deprecate the int histogram (let it overflow) and encourage to replace it over time completely with the long histogram. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
