Cloudflare K2: serverless event streams

Event streaming keeps producers and consumers apart: a service stores events in order so each reader can process them at its own pace without dropping data when a consumer lags. Cloudflare's K2, in beta, builds those logs on R2 object storage instead of a broker cluster, batching events into files and relying on the storage layer's atomic operations to keep their order; writes can take a second.
