I'm about to start a CQRS project with Axon, and I'm considering using a library called Quasar (
http://docs.paralleluniverse.co/quasar/) to manage the web service connections for the application. Quasar is an implementation of lightweight (non-OS) threads on the JVM as suspendable continuations called "fibers" using a Java agent to do bytecode instrumentation. I don't know much about the underlying concurrency model of Axon's command bus, so I'm not sure if there's some reason the two won't work well together. I anticipate that most of the commands posted to the bus will originate from these "fiber" threads that Quasar provides.
Would posting commands from within these non-standard "fiber" threads potentially interfere with Axon's asynchronous handling architecture?
Sometimes concurrency issues are hard to test for predictably, so I figured I'd ask here first.
Thanks!
