[Carter Kozak]

spring-webflux supports reactive types on undertow: https://docs.spring.io/spring/docs/current/spring-framework-reference/web-reactive.html

It may be helpful to read their undertow handler implementation, or to use spring-webflux directly.

The idea is that the handler method simply spawns an async task and whenever that async tasks completes, we send back the response without making the handler method/worker threads wait for the async task to finish.
