If you're applying non-destructive updates then you don't even need quorum to achieve consistency. You're just writing immutable data.

- pkolaczk 10y agoIf you're applying non-destructive updates without quorum, you would not get monotonic read consistency, because stale reads would be possible. You could write a row, immediately read it back from another replica and find out the row is not there, because that replica didn't get it yet. You'd have only eventual consistency.
