Iceberg is, primarily, a spec [0]. It defines exactly what data is stored and how it is interacted with. The community debates broadly on spec changes first, see a recent one on cross-platform SQL UDFs [1].

We have yet to see a largely llm driven language implementation, but it is surely possible. I imagine it would be easier to tell the llm to instead translate the Java implementation to whatever language you need. A vibe-coded language could do major damage to a companies data.

If I had a spec for something non-trivial, I probably would ask AI to create a test suite first. Or port tests from an existing system since each test is typically orders of magnitude easier to rewrite in any language, and then run AI in a loop until the tests pass.
