static file for lower zoom and serve dynamically for higher zoom #256

Closed lhapaipai closed 2 years ago

lhapaipai commented 2 years ago

I wonder if it possible to pre-generate the tiles with a low level of zoom, those which are generally the most supplied and therefore take a long time to load and on the other hand to leave to the server the care of dynamically serving the tiles with high level of zoom ?

I am thinking of this option with the cache.file (no for cache.s3) we will specify in the cache configuration a max zoom, we are launching a generation of tiles. And after starting the server, for each request, it checks if it has the cached file otherwise it generates it.

Thanks.

This makes absolutely sense and looks like a simple but useful enhancement.

Yeah, that would be nice. Right now, I'm doing this in the reverse proxy. Small-scale tiles are pre-generated and go to my "static" backend, while large-scale tiles get rendered dynamically.

Would be nice to wrap this up in the backend.

The cache_limits settings in https://t-rex.tileserver.ch/doc/reference/#tileset should do this!
