I think that it'd be super-valuable to do an analysis of an RDS Postgres deployment. Amazon is doing some dark magic with RDS that sits at this really interesting "distributed, but not that distributed" inflection point, which impacts the basic assumptions of lots of distributed database design.
I believe RDS Postgres is probably the right answer for lots of applications, especially for those that already depend on AWS for baseline availability. I'd love to see if that holds up against a rigorous analysis.
- aeyes 6y agoAre you talking about Aurora? Because in RDS the replication is just what you get out of the box.
- aphyr 6y agoI'd like this too, but I'm not sure how to do fault injection against an Amazon-controlled service.
- ashtonkem 6y agoYou’d probably have to work directly with AWS on that one, either to get a custom harness in AWS, or to find out how they configure RDS replication.
- elesbao 6y agothe setup would prob ably be pgsql primary, aurora secondaries on diff zones and something changing cross-zone or cross-region vpc setting to try to break replication ? never tried that but was hurt by rds pure pgsql cross region replication in a network outage situation.
