Cloudflare launches Workers KV Instant for faster global data replication
Key points
- Workers KV Instant uses Cloudflare's Quicksilver v2.
- Offers 100x faster p99 reads than classic Workers KV.
- Provides immediate global data updates without cold read penalties.
- Writes replicate 20x faster, within 250ms for 99% of writes.
- Uses the same Workers KV API (get, put, list, delete).
New Mode for Workers KV
Cloudflare has launched Workers KV Instant, a new operational mode for its Workers KV service. This mode is designed to provide instant global availability for data changes without incurring cold read penalties, improving performance for developers using the platform.
Powered by Quicksilver
Workers KV Instant is powered by Quicksilver v2, Cloudflare's internal key-value store previously unavailable to customers. Quicksilver was developed for fast global replication and low-latency access, and is used across many Cloudflare products for critical lookups.
Performance Improvements
The new KV Instant mode delivers significantly improved performance. It offers read latency that is over 100 times faster than the classic Workers KV mode, with p99 reads resolving in under two milliseconds. Write operations also see a substantial speed increase, with 99% of all writes replicating across Cloudflare's edge locations in approximately 250 milliseconds.
Ideal Use Cases
KV Instant is particularly suited for data that is written infrequently but read often, such as application configuration data, feature flags, and settings that require near-instant global availability. While not for all data types, it excels in scenarios where data needs to be in the 'hot path' of applications.
Familiar API
Developers can integrate Workers KV Instant using the existing Workers KV API, which includes familiar functions like get(), put(), list(), and delete(). This maintains continuity for developers already working with Cloudflare's platform.
