[GitHub] [bookkeeper] merlimat commented on pull request #3264: Update datasketches version from 0.8.3 to 3.2.0
merlimat commented on PR #3264:
URL: https://github.com/apache/bookkeeper/pull/3264#issuecomment-1147682083
@Shoothzj Just did a quick test. There are 4 bytes per each recorded sample with the new Datasketches. It would be good to understand why that is the case and if there's any way to configure DataSketches to avoid that.
