The Cache Layer Arrives After the First Cache Goes Wrong
Quarrystone Performance designs caching layers for Elixir applications, covering keys, invalidation, warm-up, supervision-tree integration, and measurement.
Field notes
The service treats caching as a sequence of operational decisions rather than a dependency installation: key cardinality, memory implications, invalidation paths, warm-up behavior, supervision-tree wiring, and repeatable measurement. Its stated scope is one application and its hot read paths, with Cachex.fetch/3 identified for lazy population and a runbook intended to cover failure response, including switching the cache off without a deploy. The page quotes a fixed fee of $6,200 CAD.
