Cool project!
How do you generate the timestamps for last writer wins? What happens if there is a tie?
Just my 2c: if I see a distributed database, the first question I ask is how it handles distributed transactions. Perhaps this topic should be higher on your FAQ, currently it is the 21st question.
There's an option in the Postgres configuration named "track_commit_timestamp" that does this automatically. It's required to be enabled when using LWW as the conflict resolution model. If there's a tie, the node with the highest node number wins.
