The site is a little thin on details and internals. I would be very interested to learn more about how they handle failovers whilst still guaranteeing "strong consistency".
- mason_s 12y agoFailovers are currently handled outside of Postgres-XL. Consistency is achieved because all of the nodes use the same transaction ids and snapshots (list of running transactions), via the Global Transaction Manager. There is no need to worry about statements being executed in a different order across the nodes.
