K2 is a serverless event log built on R2 object storage that decouples producers and consumers, trading ~1 second produce latency for unlimited retention and horizontal scaling across 335 edge cities.
Summary
Eliminates event loss from producer-consumer misalignment without running Kafka at the edge. Enables independent consumer scaling and long-term retention without dedicated infrastructure management.
Why it matters
Eliminates event loss from producer-consumer misalignment without running Kafka at the edge. Enables independent consumer scaling and long-term retention without dedicated infrastructure management.
Implementation verdict
Replaces Kafka for edge event buffering; Queues for high-scale fan-out; requires HTTP API or Worker binding integration. Public beta now—worth prototyping if you need durable multi-consumer streams, but 1s p99 latency rules out sub-second requirements.
