Is ReactorDebugAgent suitable for production?

Question

I read how to enable ReactorDebugAgent here:

https://projectreactor.io/docs/core/release/reference/#reactor-tools-debug

But I don't know if it's feasible to have such debug agent enabled by default on the production environment or only when something unusual happens?

Answer 1

The section name, as of 18th Feb 2022, is:

7.4. Production-ready Global Debugging

which seems to suggest that it is indeed suitable to be used in production. To add further context, the agent:

instruments your code and adds debugging info without paying the cost of capturing the stacktrace on every operator call. The behaviour is very similar to Activating Debug Mode - aka tracebacks, but without the runtime performance overhead.

To add some more context, we have been using this agent in a service with ~500 rps and ~5ms response time, and have not faced any issue, and have benefited from the traceback with assembly information
