> We just did some experiments on some larger clusters and found that while using IncreasingToUpperBoundRegionSplitPolicy generally works well and is very convenient, it does tend to produce too many regions.
> Since the logic is - by design - local, checking the number of regions of the table in question on the local server only, we end with more regions then necessary.
