Gatling (Open-Source)

Gatling version: 3.12.3 (open to other options though)
Gatling flavor: java scala
Gatling build tool: [ ] maven

Hi folks,

I’m currently working on performance testing some Kafka topics. I stumbled upon some official Gatling docs for executing a Kafka load test (Learn how to Load test a Kafka server with Gatling). However, I was wondering if anyone knows of any plugins / libraries that are able to run on Java 11? All the various libraries I’ve found (galax-io, tinkoff) are only compiled on Java 17 and I’m working in a Java 11 project. Does anyone know of any alternatives that are work by using Java 11?

The galax-io plugin is actually the continuation of the tinkoff one (it’s the author’s previous employer).

There’s also another 3rd party plugin for Kafka but it’s stuck on Gatling 3.9, see https://docs.gatling.io/reference/script/third-parties/.

Then, Java 11 was released 7 years ago and several projects are moving away from it. This is also a move we’re contemplating. MHO, you and your employer should consider upgrading.

Yep, but we’re not able to upgrade at the moment. Any chance you now of compiling the galax-io plugin for Java 11? Or other alternatives you recommend that could work to use Gatling for load testing a Kafka topic for Gatlinv v.3.12.3?

You can try to recompile the galax-io plugin and see if it really has a strong dependency on Java 17.
But that’s nothing something we can help with here. For 3rd party plugins, please reach out their respective authors directly, typically on GitHub.
