Iceberg is turning from a JVM table format into a library other systems embed. What that shift changes for engines, catalogs, and the spec itself.
Rust, Go, Python, and C++ Iceberg implementations change who can write the format. Why multi-language clients matter more than another JVM engine.
One suite of REST catalog operations every Iceberg platform should pass. What sameness means, where implementations diverge, and how to test it.
Remote scan planning moves Iceberg file selection into the catalog. What that changes for engines, governance, and operational cost beyond query speed.
