Hi @jsbilgi,
Sounds like a good start with Alpakka!
There is an example for reading from Kafka and writing to Elasticsearch which might help you to get started: https://doc.akka.io/docs/alpakka/current/examples/elasticsearch-samples.html#example-read-from-a-kafka-topic-and-publish-to-elasticsearch
I hope that’s kind of what you were looking for,
Enno.
