Alpakka with Akka cluster samples?


My team is trying to evaluate whether we can use Alpakka with Akka cluster to build some sort of distributed stream processing service (part of a bigger solution) … we’re using Java, most data is coming from kafka (for now) and the whole thing will be deployed to K8s.
I was wondering if there’s some example projects out there in Alpakka with Akka cluster, I can look at to try and build a poc ?

my other question is : how should we go by scaling pods up and down in K8s based on how much events we’re processing in the Akka cluster ?
