You just need to understand that EV-bases application is actually
a single process, thus all the IO should be event-driven as well,
including database requests.

If you accidentally block in a route handler for noticeable amount of time
your server will simply stop answering other queries.

That's why message queues arise -- to offload lasting tasks to a separate
process(es).
