    I’m using postres like everyone :) but i’ll give a try to duckdb. It looks promising and nice.

      Me too! I think the spatial capabilities are going to advance a lot but the good news is that you can keep some data in PostGIS and mix it with DuckDB since they have some Postgres connectivity too!

    Does this support indexing? Not just your usual spatial index like GIST(geom) but indexes on custom expressions?
    Also- great that the native geom types are fast. But do they handle change of CRS, proj, geog vs geom etc?
    AKA what if you need high accuracy distance calc

      Ah I see it’s GDAL and more coming native, cool :)

      I think it doesn’t support CRS yet and yes you can do non spatial indexes.

    How to make h3? I'm stuck there

    • @GregBreak
      @GregBreak Рік тому +1

      also spatial extension doesn't work

    • @MattForrest
      @MattForrest  11 місяців тому

      Spatial extension now comes native in DuckDB but H3 you have to build locally then use as an unsigned extension.
