Universal compaction


First of all, it’s great that it’s possible to tweak RocksDB configuration! My question is along these lines: should I prepare for any side effects if I choose universal compaction (kCompactionStyleUniversal) instead of leveled?
After some testing it seems it offers better performance on HDDs than the default.
And storage there is cheaper than IOPs…

Hi @bra,

If you choose universal, also call tiered, compaction instead of leveled, please refer to this page regarding possible impacts.
