> This problem is present for a long time ago, we maintain 2 completely different groups of classes for shuffling:
> UnorderedKVInput -> *ShuffleManager -> Fetcher*
> OrderedGroupedKVInput -> *Shuffle -> ShuffleScheduler -> FetcherOrderedGrouped*
> I don't think any of us would start to merge them in a single patch (and if so, we can wait for a complete review and fight with conflicts all the time), instead, we can make smaller refactors that make sense on their own.
> (I'm 100% this is not the first ticket addressing this but I cannot find the earlier ones at the moment)
