Debezium 3.0 loosens the Kafka Connect dependency, Estuary Flow runs managed CDC at millions of rows per second, Flink CDC 3.x has become a real ELT pipeline tool, Airbyte is the open source standard with 350+ connectors, Fivetran is expensive but keeps winning enterprise, Sling CLI handles fast local integration, and Sequin pipes Postgres directly to webhooks and Kafka. Reverse ETL with Hightouch / Census / Polytomic, cloud-native options like AWS DMS / GCP Datastream / Azure Synapse Link, database-native mechanisms like Postgres logical replication and MongoDB Change Streams, and patterns like outbox / transactional outbox / saga. With KR / JP big-tech case studies.

Debezium 3.0이 Kafka Connect 의존을 줄였고, Estuary Flow는 매니지드 CDC SaaS로 초당 백만행을 받아낸다. Flink CDC 3.x는 ELT 파이프라인 자체가 되었고, Airbyte는 350+ 커넥터로 오픈소스 표준이 되었으며, Fivetran은 비싸지만 끝없이 잘 팔린다. Sling CLI는 로컬 빠른 통합을, Sequin은 Postgres → 웹훅/Kafka를 한 줄로 해준다. Hightouch · Census · Polytomic의 reverse ETL, AWS DMS · GCP Datastream · Azure Synapse Link 같은 클라우드 옵션, Postgres logical replication과 MongoDB Change Streams 같은 DB 네이티브, 그리고 outbox/transactional outbox/saga 패턴까지. 한국·일본 빅테크 사례와 함께.
