Hi. I think that current cache eviction policy of unity accelerator is LRU. Then Its timestamp is updated when actual asset cache is requested or updated. The problem is that this timestamp update method does not work well for "live" assets. In example, project AAA has lots of FBX file and some textures. And textures are updated very frequently so cache server is full of textures'cache. Then, cache of FBX files are evicted because it is not used recently. But, FBX files are live in project and new setup of project AAA takes very long time because cache server has only caches for textures (more badly, most of them are unused anymore). So Unity editor and Unity accelerator should have something method for updating timestamp of "live" assets (in other word, existing or trackable assets) I think. It may be similar to the policy of git lfs caching algorithm. Thanks.
