> The {{size}} of a {{Log}} is calculated incorrectly due to an Integer overflow. For large topics (larger than 2 GB) this value overflows.
> This is easily observable in the reported metrics values of the path {{log.Log.partition.*.topic.<topicname>.Size}} (see attached screenshot).
> Moreover I think this breaks the size-based retention (via {{log.retention.bytes}} and {{retention.bytes}}) of large topics as well.
> I am not sure on the recommended workflow, should I open a pull request on github with a fix?
