Ah, I think you may be talking about the repeatable reads property? All readers in LogDevice are guaranteed to see the same records in the same order (aside from trimmed data).

What I was wondering really, was whether LogDevice provides total order atomic broadcast, and as such whether it solves concensus. It appears it does (or rather, it daisychains on the concensus provided by zookeeper and uses it's own fencing mechanism, similar to what bookkeeper/Pulsar does).
