Allow invalidating tile-cache for individual tiles #3701

Open Schlepptop opened 5 months ago

User Story

As a developer, I can force a map update for a tile if my tileserver notifies me of a change.

Rationale

I don't want to invalidate the whole cache when a single tile changed.

Impact

Developers use hacky alternatives such as the ones listed in https://github.com/mapbox/mapbox-gl-js/issues/2633 that may or may not work, and seem to clear the map while the new (and old!) tiles are being re-loaded.

Invalidating a single tile might prove very problematic, having said that, if you want to dig into the code and find the right way to do it, and open a PR with the relevant design and limitations it would be great!

Which issues do you see that might arise?

IDK, invalidating only part of the cache always seems risky to me, I might be pessimistic, but go ahead and try it out :-)
