> In job handling to scale for larger deployment it is essential to be able to 
> execute a job outside of the local instance. This can be in another instance 
> in the same cluster (ie when ontop of documentMk) or outside of the cluster 
> (in AEM eg via 
> [offloading|https://docs.adobe.com/docs/en/aem/6-2/deploy/configuring/offloading.html]).
>  In both cases Sling Event (Resource) stores the job in the repository 
> (/var/eventing/jobs).
> It could be useful to have another variant of job execution that is managed 
> entirely outside of the repository. With SLING-5645 a new API was created to 
> support messaging-based implementations that would fit in this category as 
> they map a job to a (one or a few) message(s). 
> This new SLING-5645 Job-API is not entirely compatible with sling.event.api 
> though.
> This ticket is to track an effort to provide a messaging-based implementation 
> for sling.event.api - namely for Kafka. The goal is to become a drop-in 
> replacement of sling event without much need for change on the user side of 
> the sling.event.api.
> This might not right away become part of sling, but might start off in the 
> contrib section - to underscore that it's not something supported, at least 
> as of yet.
