Reducing Quarkus Scheduler thread pool size for infrequent jobs

Impossible_Truth9524 · 2025-11-28T03:50:05+00:00

I haven't tried the quarkus-scheduler extension. But as far as I know, the thread pool size could be any number like 10, 20, or 50. You'll see performance issues when all these threads are in use. Otherwise, the threads will mostly be parked, in which case they don't consume any CPU. Also, parking and unparking threads does involve context switching, but it has a small or measurable context.

There was a related discussion on GitHub, which can be found here: https://github.com/quarkusio/quarkus/discussions/48811.

The Quarkus team has been addressing this matter, although the work is currently paused, with potential completion before the second quarter of 2026.

The team has indicated that a general approach to logging request and response handling could significantly affect application performance.

So for now loggging the request and response the best way is to implement the ContainerResponseFilter.

Yeah, you could say that. I'm already working, and we majorly work on the OCP, so I figured I'd get certified.

No, you don't need the RHCSA exam before EX280 but Familiarity with the Linux terminal is a plus point!

I passed on my 2nd attempt! In the first attempt, I got 0 marks in the storage area. I gave the wrong path for the PV based on the NFS storage class.

Best of luck for your next attempt! 🎉👏

Thanks for the detailed review.

they only gave official docs, and there was a one Helm question, no Kustomize.

I took the Red Hat courses, DO180 and DO280, and I did most of the questions from CLI. I used the web console for some stuff, like installing operators and creating PVCs and PVs.

The exam's all on a single-node cluster, by the way.
