I think eBPF has also great potential to help JVM-based languages. Especially around performance aspects even comparing to the current java agents which use bytecode manipulation.
The article mentions avoiding GC pressure and separation between recording and processing as big wins for performance for runtimes like Java but you could do the same inside Java by using ring buffer, no?
Interesting idea. I think that as long as you able to do processing, serializing and delivery in other process and save this work from your application runtime you should see great performance
