Supercharge your GraphQL with Ktor and GraalVM
summary
Live coding shows GraphQL Kotlin + Ktor serving a code-first schema, with schema generation via Reflections and explicit polymorphism mapping required for native images; slow field work moves from blocking sleep to suspend functions to avoid thread stalls. GraalVM native image boots near instantly — measured 0.02 seconds startup — at the cost of extra build work: native image adds ~1+ minute to build and requires reflection metadata and explicit type lists. The demo compiles and runs successfully.
