Aurora Serverless v2 support for Data API

Well, we are many that are eagerly awaiting some kind of response from AWS... I can only recommend you to raise feature requests through your Support with AWS and contact your AWS account rep. and ask them to add a feature request on your behalf.

The RDS Proxy and Data-API aren't really comparable "function-wise", but they both offer connection pooling (which is the most important feature I guess). The RDS Proxy is a "service" built into the underlying AWS infrastructure which can be used by some other AWS functions, e.g. Lambdas. The Data-API, is what the name says, an API which we can call from anywhere over HTTP.

AppSync can also, natively, use the Data-API as a resolver using VTL scripts (something we do a lot), but AppSync can't use a RDS Proxy. To use RDS Proxy with an AWS Service that doesn't have "native" RDS Proxy Support you alwyas have to go through a Lambda, something that adds latency as well as more code that must be maintained. This we can avoid with the Data-API!

I really hope that AWS listens to us customers and while being thrown under the bus right now, I hope they ca grab my foot and pull me out from there by announcing the Data-API for v2!

We are stuck on v1 (that has the world's worst scaling) because of this and we really need to go to v2 to get a functioning scaling in place but can't because of AppSync and the lack of support for it in v2... :(
