• Moving off RDS is possible using logical replication with a publisher/subscriber model to transfer data between databases 3:05
• Large database migrations face challenges with initial data copying, but can be managed through multiple publishers/subscribers and parallel dump operations 3:42
• The video also covers a novel approach to partition table migration with minimal downtime by moving data incrementally 15:02

Now, they didn't really leave the cloud. They were still on the internet. they just were running their own servers at a different hosting provider. And I know what I've done to try to minimize cloud costs is mostly just use the commodity services of AWS like EC2, EBS, S3. But a lot of the more specialized services I've avoided because I know they tend to put a pretty high markup on those. And one of those services that I don't use is RDS. Why? Well, I already have sufficient postgro…
