Summary
Introduced Workers KV, a highly distributed, eventually-consistent, key-value store designed for Cloudflare's global network. It allows storing up to 1 billion keys (2kB each) with values up to 64kB, offering global consistency within 10 seconds and high read throughput (100k+ reads/sec/key). Pricing is integrated with Workers compute minimums, with additional storage and reads billed separately. Use cases include API gateways, dynamic data serving, configuration management, and connecting disparate systems.
