The concept of "zero-copy" integration between Apache Kafka and Apache Iceberg, which suggests that Kafka topics could directly function as Iceberg tables, is critiqued for its inefficiencies and potential pitfalls.

Additionally, it highlights challenges related to schema evolution and performance optimization for both streaming and analytics workloads.
