Answer 1

you can use the @DelegateAsync keyword on your service methods to get them executed by the global executor service.

The documentation also describes how to handle result events : https://grails.github.io/grails-doc/latest/guide/async.html

Answer 2

You know that spawning arbitrary threads and leaving them on their own can be dangerous? You can end up with dozens of export threads running and no way of controlling them.

Better ways of doing this include using quartz scheduler and run export jobs whenever you need to, have an async (message driven?) worker apps/threads and some web containers provide built-in worker services.

Simply put, there's plenty of ways of doing this securely and in a controlled manner.
