Description

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.)
