Thanks! I look forward to reading about implementation details.
It does seem like documentation of Citus Cloud HA and disaster recovery behavior is a bit light, compared to e.g.
- http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concep...
- https://devcenter.heroku.com/articles/heroku-postgres-ha
"In addition to continuous protection which is explained above, high availability is available if your application requires less exposure to downtime. We provision stand-bys if you select high availability at provisioning time. This can be for your primary node, or for your distributed nodes." https://docs.citusdata.com/en/v6.1/cloud/features.html
Please let me know if I've missed any resources on this topic!
