There's some really good explanation (and implementation) in the Caffeine library[1]. Ben Manes worked with Gil Einziger on the implementation and actually contributed to an updated version of the TinyLFU paper, IIRC. Gil has a ton of very relevant work[2][3] around cache admission, control, and information density. Unfortunately cache admission is an understudied and woefully unimplemented area of CS & computer engineering as far as I can tell. There's some decent work around hardware layer problems, cache line insertion/eviction/etc, but not much in general purpose software caching. Gils research was definitely the most relevant and relatable when I was involved in this area a few years back.
