I have code which uses File::Cache for both disk-based lookup tables ("Have I seen X before?") and storing metadata about an item. The API is fine, but filesystem performance with very large caches is just too slow (even after playing with the "cache_depth" param.), so I'd like to use a database to store this information instead. (I'm not too worried about speed, but it needs to be lightweight). However, I can't seem to find any module that does this. Am I looking in the wrong place, or should I just write my own? :-)
