I've been going back and forth on that as well - why did you guys end up switching?

Bunch of reasons but can be boiled down to: • lack of control over instance - limited access to config, locked in a kindergarten, minimal extensions • aurora allowed us to talk to lambdas directly from PG via aws_lambda extension which was pivotal for some required event-based functionality (on aurora sls this would have to be done via a polling mechanism) • access to the WAL - we need this to implement a custom CDC pipeline. Aurora itself makes use of this access to enable continuous backups • no more Data API - we can connect using basic parameters which is more flexible

The point about aws_lambda extension was something that was interesting to me as well

yeah same here. It's a neat concept but the execution has so many constraints and tradeoffs
