Cloudflare Rearchitects Workers KV Following GCP Outage, Achieves 40x Performance Gain
Cloudflare has recently redesigned Workers KV with a hybrid storage architecture that automatically routes objects between distributed databases and object storage based on size characteristics, while operating dual storage backends. This change improved the p99 read latencies from 200ms to under 5ms for their global key-value store while handling hundreds of billions of key-value pairs.
