maptiler
data.json just shows the first 100 values of attributes
Hey, when I retrieve the /data/mbtiles.json, /data.json or index.json, I only get the first 100 values of the attributes I use for my LineStrings, even if the count is over 100. Is there a way to configure how much values are shown in the json? I couldn't find anything in the documentation.

Is it the same on the index page? are you able to access the files that arn't listed there at all?
I am not aware of a parameter or limit... we would have to look around the code and see where that limit may come from
Yes it's the same on the index.json and yes I can access the files that arn't listet. The parameters with the correct values are also available in the not listed files.
Is it possible that a request timeout was hit? How long does the query take and is it always limited to exactly 100? By LineString I assume a geojson source?
The query takes around 200ms. The limit is always exactly 100. The Tileserver serves mbtiles, which are generated by tippecanoe from a geojson.
@AimbotNooby I have been down in the rabbit hole and found some batch and chunk sizes on my way down, but everything was fine. The "issue" is hard coded here: https://github.com/felt/tippecanoe/blob/423fea15448386ccc832686f55f072b1f97f73ba/mbtiles.cpp#L27
I could verify it with my own geojson file /o\
