Declarative Event-Driven-Application Patterns with Knative
Talkat AppDeveloperCon Europe 2024 · on Tuesday, 2024-03-19· at 16:25· Pavilion 7 | Level 7.3 | Room S04·
summary
Knative Eventing and CNCF CloudEvents are used to build declarative EDAs on Kubernetes with concrete pieces: a Broker HTTP endpoint, Trigger filters, a Sequence CRD for ordered steps, and a Kafka sink that persists CloudEvents. Patterns shown include retries with backoff and a dead-letter sink that adds base64 conative error data, the dataRef extension (claim check) to avoid large payloads, and an outbox approach using Debezium CDC to reliably publish DB changes. Schema validation is noted as not yet available.
