A work in progress comparison of web frameworks for Kotlin & Go microservices.

The intent of this project is to provide a relative comparison of the performance of basic microservices built using different technologies. It is meant to be an expanded take on Practical Performance Comparison of Spring Boot, Micronaut 1.3, Micronaut 2.0

WIP: Short Term vs. Long Term

The initial goal of the project is to support a generic GET endpoint that returns random data generated by Faker.
Expand to support CRUD operations backed by a Postgres datastore. The goal will be to compare performance of a more realistic service, as well as sense of how Spring Data JPA, Spring Boot with jOOQ, Micronaut Data JPA, and several other webframeworks using Exposed ORM stack up in a relative sense. This could be expanded to include other ORM/persistence frameworks.

Curent Implementations

Random Address Data

Spring Boot 2.x
Micronaut 2.x
Quarkus
Ktor
http4k
Kooby/Jooby for Kotlin
Javalin

Considerations for Future Additions

Longer term thoughts for additions.

Jetty vs Netty vs Tomcat vs ?
JVM comparisons (AdoptOpenJDK, Corretto, GraalVM, etc)
Jackson vs. GSON vs. kotlinx.serialization vs ?
Dependency Injection alternatives
other languages? (Rust, etc)
