GoKawiilCloudflare launches K2, a serverless event-streaming service, in public beta
Cloudflare has released K2, a durable event streaming primitive on its Developer Platform, now in public beta. K2 stores incoming events as an ordered log built on R2 object storage, letting multiple consumers read data independently and at their own pace without losing events during downtime.
GoKawiil's interpretation of the reporting above, not reported fact.
By decoupling producers from consumers, K2 could let developers build systems like fraud detection or analytics pipelines that read the same event stream without risking dropped data when one consumer lags or goes offline. Cloudflare says it originally built K2 internally to support its Pipelines product, suggesting the company is now exposing infrastructure it built for its own stream-processing needs as a general-purpose tool for customers.
- Cloudflare K2 is a new serverless, durable event-streaming primitive now in public beta.
- It stores events as an ordered log on R2 storage, supporting multiple independent consumers and long-term retention.
- K2 originated as internal infrastructure for Cloudflare's Pipelines product, which requires guaranteed, durable event storage.
