Traditional caches give you the same tradeoff: pick one refresh interval, and it applies to everything. Stable data gets refreshed more than it needs to while volatile data sits stale longer than you'd like. Tune one, you compromise the other.
That's why we built Adaptive Cache, which is available today as part of the Readyset Platform. Adaptive Cache adjusts the refresh interval per cached result based on how frequently that result actually changes, with no manual tuning required.
In our testing, p95 staleness dropped 97% compared to a standard TTL cache, with only a 60% increase in upstream refresh load instead of the 490% increase you would need to achieve the same result by manually shrinking the interval.
This is a key step toward caching that's truly invisible, no tuning, no babysitting.
