I admit I only dip my toes into the Java ecosystem occasionally. How low is low memory usage? The last microservice-oriented Java framework I used was Spring Boot, but I don’t know that I’d call it lightweight.
I hope no one calls it lightweight. We've been running a few or our own benchmark tests for various frameworks and we have found that Quarkus running on GraalVm is the definition of lightweight.
Thanks for pointing me towards Quarkus! That looks really cool!
Edit: And yes... the folks I was working with were excited at how much lighter-weight Spring Boot was compared to whatever it was they were using before. When I showed them a Go-based server just using net/http, they almost had a stroke!
