Caching strategies: cache-aside, write-through, TTL
Patterns for keeping fast caches and slower databases consistent and available under load.
"I need reads to be fast without letting stale or missing data break my service during traffic spikes."
Cache-aside: application reads cache first and falls back to DB then populates cache. Write-through: writes go to cache and backing store synchronously. TTL: cached items expire after a set time to bound staleness.
