Summary

dbmazz is a Rust daemon for streaming database changes into a sink. It reads PostgreSQL changes through logical replication and streams inserts, updates, and deletes. The project reports sub-second replication lag and about 11 MB of resident memory per daemon. PostgreSQL and MySQL are listed as sources; stable sinks are StarRocks, PostgreSQL, and Snowflake, while S3/Iceberg is on the roadmap. Each instance handles one replication job. The project provides an ez-cdc CLI quickstart demo and an official Docker image for running the daemon. Its CLI runs on Linux and macOS for amd64 and arm64. The maker lists Prometheus metrics, gRPC reflection, an HTTP control plane, and a live terminal dashboard. It says automatic setup can create publications, replication slots, sink tables, and audit columns. The self-hosted engine is free, and the free BYOC plan deploys in a customer's AWS or GCP account; support and optional PrivateLink connectivity are charged separately. dbmazz uses Elastic License 2.0, which permits commercial and non-commercial use but restricts offering it to third parties as a managed service.

Who it is for

dbmazz suits teams seeking streaming PostgreSQL change data capture without operating a streaming platform. It is also an option for users who want to self-host or deploy in their AWS or GCP account.

What is good

  • Free self-hosted engine.
  • Streams inserts, updates, and deletes.
  • Official Docker image and CLI quickstart demo.
  • Lists Prometheus metrics and a terminal dashboard.

What to know first

  • Each instance handles one replication job.
  • S3/Iceberg is listed as roadmap, not stable.
  • Managed-service offering to third parties is restricted.
  • BYOC support and optional PrivateLink cost extra.

Verdict

dbmazz offers a focused CDC daemon with listed stable sources and sinks, plus self-hosted and BYOC options. Check the one-job-per-instance limit and license restriction against your deployment plans.
