> Technically, StoreEngine can be used to achieve any permutations of things, but to make
it more convenient to replace compaction policy/compator in standard schemes like tier-based,
we can add separate hooks in DefaultStoreEngine (as long as custom ones conform to its default
expectations e.g. flat list of sorted files, etc.)
