 We have a strategy where cache is deleted after a retention period automatically and no new cache is created if there is not enough disk space.

-PMA.core will not cache tiles or thumbnails if there is not enough disk space (as defined in the [[cache_settings|settings]]).
+Extracted tiles from [[https://realdata.pathomation.com/what-whole-slide-images-wsis-are-made-of/|WSIs]] are stored in a cache repository. This is Just In Time (JIT) caching: the tiles are only stored in the cache after being generated for the first time.
+When many people look at the same slide, they are typically interested in the same regions of interest and slide details. This means that as a system is used over time, almost all of its accessed content will be available through the tile cache. Tile caching in this regard also makes PMA.core a much more scalable system than it would be without this mechanism.
