Workers KV is faster than ever with a new architecture

We’re excited to announce a significant performance improvement coming to Workers KV, focused on dramatically improving cold read performance and reducing latency, even for long tail access patterns.

Developers using KV have seen great performance on hot reads, but ask why their 95th percentile latency — often on a key (or set of keys) that hadn’t been accessed recently or in that region — was higher than expected. We took this feedback to heart: we’ve been working feverishly on a new caching layer for KV behind the scenes, which enables customers to achieve much more frequent hot reads, reduced worst case latency times, better flexibility and control over cache TTLs, and much faster consistency over our previous iterations, and it’s now live for all KV users.

The best part? Developers using KV don’t need to change anything to benefit from this increased performance.

What is Workers KV?

Workers KV is a key value store designed for read heavy use-cases and applications powered by Cloudflare’s network. KV’s focus on read-heavy use-cases allows it to serve hot (cached) reads in milliseconds, which makes it ideal for storing per-application or customer configuration data, routing configuration, multivariate (A/B testing) configurations, and even small asset Continue reading

Cloudflare Queues: messages at your speed with consumer concurrency and explicit acknowledgement

Communicating between systems can be a balancing act that has a major impact on your business. APIs have limits, billing frequently depends on usage, and end-users are always looking for more speed in the services they use. With so many conflicting considerations, it can feel like a challenge to get it just right. Cloudflare Queues is a tool to make this balancing act simple. With our latest features like consumer concurrency and explicit acknowledgment, it’s easier than ever for developers to focus on writing great code, rather than worrying about the fees and rate limits of the systems they work with.

Queues is a messaging service, enabling developers to send and receive messages across systems asynchronously with guaranteed delivery. It integrates directly with Cloudflare Workers, making for easy message production and consumption working with the many products and services we offer.

What’s new in Queues?

Consumer concurrency

Oftentimes, the systems we pull data from can produce information faster than other systems can consume them. This can occur when consumption involves processing information, storing it, or sending and receiving information to a third party system. The result of which is that sometimes, a queue can fall behind where it should be. Continue reading
