The current features of AWS AppSync are enough for any developer, but it has some areas for improvement. AWS AppSync can provide first-class support for SQL RDS since writing SQL via VTL is clunky and limited. I suggest native richer SQL resolver support because that is what I am looking for in AWS AppSync. My next suggestion is to promote JS-based resolvers as default, which will be better for the development experience since most developers use JS-based resolvers in their day-to-day life. Another suggestion is to provide built-in distributed tracing, which is a must. It needs to have a built-in distributed tracing view so that anyone can see reports and easily trace any issues. I suggest improving VTL debugging enhancement, observability, better SQL resolver support, strengthening local development tooling, promoting JS resolvers, and adding query performance insight could significantly improve the developer experience.
