The architecture systematically separates logical semantics from physical state across three independent dimensions: topology (consistent hashing decouples ring positions from data placement, making node operations stateless), storage (message queue offsets survive partition trimming via base offset adjustment), and deletion (tombstones and delete markers decouple the logical fact of deletion from physical data removal), making logical-physical independence a cross-cutting architectural principle rather than a per-system choice.
Consistent hashing, queue offsets, and deletion metadata are three instances of the same logical-physical decoupling strategy
