Review comment:
Although IncreasingToUpperBoundRegionSplitPolicy override the
shouldSplit, but does not override isExceedSize.
IMO, even if there is only ConstantSizeRegionSplitPolicy, the ref check
should be precondition of size check, since if any store has ref file, all
stores are no need to check size.
