Show HN: Secache – Sampling Eviction Cache

Snawoot — Sun, 07 Dec 2025 10:22:22 +0000

I'd like to share a curious cache implementation I recently came up with: https://pkg.go.dev/github.com/Snawoot/secache

It's a small (<200 LOC) simple cache implementation. What makes it curious is how it approaches item expiration. Usually in-memory cache libraries either scan entire key space from time to time or maintain priority queue to kick out oldest items. This library handles item expiration differently: on each new item addition it performs fixed small number of eviction attempts against keys selected randomly. This way it is able to maintain stable high ratio of valid elements in cache.

What's more important is that validity of item is decided by user-provided function. That allows to bring in your own notion of item validity: item age, frequency of the item use, internal state of shared object and so on. E.g. I use it, among other things, to evict per-user instances of "golang.com/x/time/rate".Limiter as soon as token bucket recovered to initial state and limiter has no shared lock being held on it.

New comment by Snawoot in "Consistent hashing"

Snawoot — Fri, 03 Oct 2025 13:44:20 +0000

I also double that rendezvous hashing suggestion. Article mentions that it has O(n) time where n is number of nodes. I made a library[1] which makes rendezvous hashing more practical for a larger number of nodes (or weight shares), making it O(1) amortized running time with a bit of tradeoff: distributed elements are pre-aggregated into clusters (slots) before passing them through HRW.

I've made a couple of modules which allow canonicalize maps and slices of comparable elements, making their canonical handles also comparable:

I think I found some solution for arenas in Go: https://pkg.go.dev/github.com/Snawoot/freelist

Has some shortcomings, but I think it should work.

> What ever happened to providing a good service?

I'm getting an impression it's just not profitable enough. For many years I get a feeling that business is considered sound only if it is superprofitable (not exactly the right term, but still) in order to cover all losses.

Probably it's because of market competition required to be at least noticed. Some companies' spendings for marketing are greater than for R&D, production and operations combined. Maybe we got ourselves into a situation where everywhere competing for low-hanging fruits or trying to make customer believe it's the service they need while all of it doesn't really overlap with real society needs.
