AI Analysis

●MidShip It

Background sweeper refreshes hot cache entries before expiry, but the API is still experimental.

Strengths
  • •Coalesces concurrent cache misses into a single recomputation to prevent thundering herds.
  • •Exposes /zinda/stats endpoint showing hit rates, stale serves, and refresh errors instantly.
  • •Middleware option caches entire HTTP responses without modifying individual endpoint code.
Weaknesses
  • •README explicitly warns against production use while core ideas are still being validated.
  • •Competes with mature alternatives like Redis, Cachetools, and FastAPI-Cache that are stable.

Post Description

Hi folk,

I am working on a small experimental freshness-first caching library and wanted some design feedback. before i take it further.

Instead of wiring up invalidations by hand, the cache would watch your function by hand and cache should automatically infer the behavior and keep the data fresh.
