Every caching layer introduces a fundamental challenge: how do you keep two data stores in sync when writes happen? Get this wrong and you’ll face stale reads, lost writes, or both. Get it right and…
Read more →Redis caching can reduce database load by 60-90% and improve response times from hundreds of milliseconds to single-digit milliseconds. But throwing Redis in front of your database without a coherent…
Read more →Redis is more than a cache. Sorted sets, streams, and HyperLogLog solve problems that key-value can’t.
