If you only need statless transformations, I guess that fs2, zio-streams, and alpakka kafka are good solutions, and it's just a matter of personal preference. But zio and fs2 are definitely lightwheight when you compare it with akka streams. I see a lot of comments against ZIO streams that are not supported by the facts, since https://github.com/zio/zio-kafka has more contributors than https://github.com/fd4s/fs2-kafka. Here are some materials if you want to learn more about zio-kafka: https://www.youtube.com/watch?v=GECv1ONieLw https://scalac.io/blog/streaming-microservices-with-zio-and-kafka/
ZStream is part of the core ZIO library. It's not maintained by one person but by the entire core team and in the upcoming version 2 saw major updates.
We were using Spark extensively for many years, transforming JSON and TSV.
