transform feature property

[farfromrefug]

I use tippecanoe to generate contours line.
I use gdal_contour -i 10 -a ele to generate the geojson to pass to tippecanoe.

I also need to use ogr2ogr to transform the ele to div as such:

ogr2ogr -dialect sqlite -sql "
SELECT
  ele,
  CASE
    WHEN ele % 1000 = 0 THEN 1000
    WHEN ele % 500 = 0 THEN 500
    WHEN ele % 250 = 0 THEN 250
    WHEN ele % 200 = 0 THEN 200
    WHEN ele % 100 = 0 THEN 100
    WHEN ele % 50 = 0 THEN 50
    WHEN ele % 20 = 0 THEN 20
    ELSE 10
  END AS div,
  geom
FROM
  contour
" /vsigzip/$name-contours-10m.geojson $name-contours-4326-10m.gpkg

Now ogr2ogr is really slow and also prevent me from using tippecanoe in "parallel".

I was wondering if there was a way to get rid of the ogr2ogr step. Is there any way to transform feature properties in tippecanoe (before filtering) so that ele would become the modulo div?

Thanks
