Improve automatic reload on Camel route
Describe the feature here
reloading a relatively simple Camel route is taking 6 seconds (on my machine).
a log is suggesting some ways to have small changes ot be faster (like in my case changing the content of a string in a log message):
2025-11-07 18:02:58,992 INFO [io.qua.dep.dev.RuntimeUpdatesProcessor] (Timer-0) Live reload took more than 4 seconds, you may want to enable instrumentation based reload (quarkus.live-reload.instrumentation=true). This allows small changes to take effect without restarting Quarkus.
(and yes I realize that there can be a lot of different use cases and a lot of work but maybe some quick win available?)
Reloading a relatively simple Camel route is taking 6 seconds
Can you share a reproducer?
- start with mvn quarkus:dev
- after the route is running, changing the string in the setBody().simple
Ok - so in this case it's extra time taken for graceful shutdown of the Kafka consumer / producer.
You can speed it up a bit with:
%dev.camel.component.kafka.shutdown-timeout=1000
We could perhaps force this config automatically in dev mode. Not sure how safe it is though. I noticed if you set smaller timeout values then you get some ugly InterruptedException messages in the console logs.
