Caching Strategies
Cut latency with caches
Caching stores computed or fetched results for reuse; choose keys, TTLs, and invalidation rules to balance freshness and performance.
- ttl
- invalidation
- write-through
- write-back
- cache key
Decide What to Cache
Cache read-heavy, slow-to-compute, or external call results.
Set Policies
Pick TTLs, size limits, and eviction; choose write strategies.
Invalidate Safely
Purge on writes or use versioned keys to avoid stale data.
