  • Python deserves a good in-memory cache library!

    If you know Caffeine(Java)/Ristretto(Go)/Moka(Rust), you know what Theine is. Python deserves a good in-memory cache library.

    Thanks for the feedback. I am aware of Moka. We used it on a work project but stopped because we had a couple of issues with it. The main one was: which I think is fixed now and a smaller issue which was caused by the Quanta crate crashing on AMD chips (also fixed).
  • Writing a concurrent LRU cache

    Ya, I saw concache but I looked into it and it doesn't implement what is needed. Each bucket has its own linked-list backing (hence "lock-free linked list buckets"). An LRU needs each value in each bucket to be part of one linked list I believe. After posting this I realized my line of research was failing because it was state of the art five years ago. Caffeine replaced `concurrentlinkedhashmap` in the java world (by the same author). A rust version of that is Moka. These are much more complicated than a concurrent LRU but faster (aka more state of the art). Another rust crate is Stretto which is a port of dgraph's Ristretto (in go). The question becomes is it worth it to essentially port `concurrentlinkedhashmap` to have a great concurrent LRU when there are more state of the art caches out there.
  • Stretto - a thread-safe, high-performance, high hit-ratio cache.

    How does it compare to ?

    Part 1 makes sense, 2 is a little confusing. The blog post ends up using this Java library: which implements those ideas. I am curious if there is something equivalent implemented in rust, or is it something I should write? Also is there an even better way to do thread-safe performant LRU?

What are some alternatives?
