Pass an Arrow (Vector) to getFilterValue in GeoArrowSolidPolygonLayer

[Phonom]

I understand that "Any accessor (layer property prefixed with get*) can be passed an Arrow Vector"

But I'm having some trouble trying to pass a vector to the getFilterValue accessor when creating a GeoArrowSolidPolygonLayer , I'm trying to do this :

const buffer = await fs.promises.readFile(my_arrow_path);
const data = tableFromIPC(new Uint8Array(buffer));
...
let geometry = data.getChild("geometry")!;
let datetimeColumn = data.getChild("datetime")!;

const layer = new GeoArrowSolidPolygonLayer({
    id: state.id,
    data: data,
    getPolygon: geometry,
    getFilterValue: datetimeColumn,
    ...
}

With that nothing appear. I don't think I have any error or logs either...
My arrow is made with GeoPandas with the function "to_arrow(geometry_encoding="geoarrow")"
And the dataframe have 3 columns "datetime", "value" and "geometry".

I have another solution that's works :

    getFilterValue: (
      _: unknown,
      info: { index?: number; data: any; target: [number] }
    ) => {
      const row = info?.data?.data?.get?.(info.index ?? -1);
      const value = row?.datetime;
      return value;
    },

The layer appear with that, but I'm having some performance issues.

getFilterValue isn't a prop defined by GeoArrowSolidPolygonLayer.

That's defined by the deck.gl DataFilterExtension instead. I think you have to pass in the accessor data manually. I can't recall exactly. You can inspect how Lonboard does it here, though it might not be easy to follow how the extensions interact with the main layers.

Also, in the latest beta versions and upcoming release the layers change from taking in "column" inputs (i.e. Vector) to "contiguous array" inputs (i.e. arrow.Data).
