We can either improve the seda component to have an correlation map with timeout and the likes (eg like camel-jms have).
But this component current behavior has been as it has been since Camel 1, where the requestor will wait for the reply.
What we need is an async correlation manager (like camel-jms).
So either we
- change the SEDA implementation
- add a new component
In the old days with JBI there was the camel-nmr component that has this strategy, but it was replaced with JMS as the solution as you have all of this out of box with JMS, and it came out of the box with ServiceMix
