Geometry type support for DuckLake spec

[houstonwarren]

Hi team,

Thanks for all your work on DuckLake — I’ve been trying it out and it’s been fantastic so far. Really refreshing coming from the Iceberg world.

Given that Parquet now supports geometry/geography types, Iceberg has recently added native geo types, and DuckDB offers strong spatial support via its extension, I’m wondering if there are any plans to add a geometry type to the DuckLake spec?

Is its current absence due to the pure SQL-based catalog design, where only certain backends support spatial extensions?

Geometry support would be a killer feature for me and would make DuckLake an ideal fit for geospatial work given the strength of DuckDB in that area. Appreciate any insights — and thanks again for the great work!

Ah apologies! I did search, but clearly not well enough.
