One binary. No Kafka. A single Rust daemon that streams PostgreSQL changes to StarRocks, Snowflake, or another PostgreSQL with sub-second replication lag — 23–360× lighter than [Debezium standard deployments][deb-faq] and 727× lighter than [Airbyte's minimum recommendation][air-deploy].

No Kafka, no Flink, no ZooKeeper, no Connect cluster, no schema registry — and no batch windows. The whole thing is 30 MB on disk and 11 MB resident in memory — about the size of an idle shell session, not a database tool. Run it from the official Docker image or build it from source. Each instance handles one replication job. The ez-cdc CLI in quickstart mode — live throughput, lag, source vs target row counts. --- At a glance How dbmazz compares to other open-source CDC tools on resource footprint and deployment complexity — the two dimensions where dbmazz is purpose-built to win. dbmazz Debezi","default_branch":null,"files":null,"tree":[],"storefront":"/r/ez-cdc","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/ez-cdc/dbmazz/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
