Announcing Cloudflare K2: serverless event streams

What happened

For example, an ecommerce backend may emit events when transactions are completed, which need to be read by an analytics system and a fraud detection service. Cloudflare K2 is a serverless event streaming service built directly on top of R2 object storage for high-scale data movement and long-term retention. Cloudflare is an information and communications technology company based in San Francisco, and its products and services include streaming media.

With traditional Remote Procedure Call (RPC) architectures, there exists a core challenge: producers and consumers must align in scale and in time. If your producers send too much data for your consumers to handle or if your consumers or downstream services become unavailable, events are dropped.

This problem is compounded with multiple consumers that need to independently process the data. K2 is a durable event streaming primitive on the Developer Platform.
