It’s been a few months already since I’ve started working for good with distributed systems using (micro)services and asynchronous processing via service bus. Many issues and question raised and one of these was how to not lose the information about commands and events being processed and even more importantly, how to notify the user once the request has completed? I’ve had to come up with some solution that seems to be sufficient (at least for now) and I’d like to share it with you.
