Since debug flags can significantly change the functioning of a system, they aren't distributed as a matter of course. In addition, since they're debug (internal) "helper" tools, they are subject to change at any time.
Most commonly, these flags will be provided by a support team member who will advise how, when and why to apply them. So no, there is no (as far as I know) publically available list of debug flags.
Hi Joseph, I think it will be very helpful to have this kind of list ready in case of troubleshooting. I have myself used couple of debug config keys. We do realize that these comes with warning.
Currently we had a issues with skipped and discarded purepaths due to high heap consumption along with GAT difference after upgrading to 7.0.12, we did multiple workarounds to fix the issue with the help of support and was finally resolved by degrading it to 7.0.7. so to have an initial analysis and more debug information I had requested for the same.
Although it is resolved now, I would like to have that level of information which can help me to analyse the system if anything is breaking down. It will definately save our lot of time.
