Thanks! I didn’t want to bring up existing tools unless I knew them in enough detail be thorough and accurate. That said, Vitess can apply query limits as described under Insights. Migrations seem to have dozens of solutions from home-grown to enterprise. Not sure about reducing deadlocks, I’ve seen academic articles in passing that I don’t think have been commercialized yet. Lambdas are common with NoSQL databases like Firebase and DynamoDB. Supabase is working on a Functions feature which is interesting because it’s on Postgres, but they haven’t released many details.
What I’d really like to see is how the combination of features could be more than the sum of its parts.
