I'm also building in the lakehouse space and anecdotally have seen more excitement around Iceberg over delta lake just because of its completely open source origins. Iceberg has evolved faster and has had more contributions from a more diverse set of contributors than Delta Lake. Not sure if this will change with a Snowflake <> Tabular acquisition but I'd easily bet on Iceberg if current trends continue.
We agree. We plan to bring Iceberg support as a first-class citizen as soon as we can, but unfortunately the support in Rust these days is still limited. We and the community are working on it
