Possible to do zero allocation for this too? https://github.com/VictoriaMetrics/fastcache

do you have an alternative to kv lru cache that has zero allocation? fastcache has 2b allocation per operation https://github.com/VictoriaMetrics/fastcache

It looks quite domain specific. I'd say a better candidate would be hashicorp/golang-lru.
