Introducing Workers KV Instant — powered by Quicksilver
Cloudflare has launched Workers KV Instant, a new storage tier achieving sub-2ms p99 read latencies. The service guarantees 250ms global replication across the entire Cloudflare edge network.
Verified State Diff
Impact & Verification Analysis
Cloudflare Workers developers, distributed systems architects, and enterprise users requiring low-latency global state management.
This release bridges the gap between edge-based key-value storage and high-performance database requirements, enabling more complex, stateful applications to run entirely on the edge without sacrificing speed.
Full Fact Overview
Workers KV Instant leverages the Quicksilver distributed configuration store to bypass traditional eventual consistency limitations inherent in standard Workers KV. By moving data closer to the execution environment and optimizing the replication pipeline, Cloudflare has effectively eliminated cold-read penalties. This architecture allows developers to maintain the existing Workers KV API while gaining performance characteristics suitable for high-frequency, latency-sensitive applications.
