Jack Vanlightly lays out an argument:
Over the past few months, I’ve seen a growing number of posts on social media promoting the idea of a “zero-copy” integration between Apache Kafka and Apache Iceberg. The idea is that Kafka topics could live directly as Iceberg tables. On the surface it sounds efficient: one copy of the data, unified access for both streaming and analytics. But from a systems point of view, I think this is the wrong direction for the Apache Kafka project. In this post, I’ll explain why.
Read on for an explanation of what “zero-copy” means here, as well as Jack’s position on the matter. I think it’s a solid argument and worth the read.
