Key insights cover why three explicit layers beat one, how Kafka Connect's Dead Letter Queue and Schema Registry enforce trustworthiness, the nuances of CDC including handling absent events, why audit columns (VALID_FROM, VALID_TO, DELETE_FLAG, JOB_RUN_ID) are operationally essential rather than compliance decoration, and what distinguishes a reusable data platform from a one-off pipeline. ## Full article daily.dev links to this article rather than hosting it.
