The record

What it does: dbmazz is a Rust daemon that reads PostgreSQL changes through logical replication and streams inserts, updates, and deletes to a sink.
Performance: The project reports sub-second replication lag and about 11 MB of resident memory per daemon in its README.
Sources and sinks: The README lists PostgreSQL and MySQL sources, with StarRocks, PostgreSQL, and Snowflake as stable sinks; S3/Iceberg is listed as roadmap.
Setup: The project provides an ez-cdc CLI quickstart demo and an official Docker image for running the daemon.
CLI platforms: The project README says its CLI runs on Linux and macOS for amd64 and arm64.
License: dbmazz uses Elastic License 2.0, which the README describes as allowing commercial and non-commercial use while restricting offering it to third parties as a managed service.
BYOC and data location: EZ-CDC says BYOC runs in the customer's AWS or GCP account and that its data stays within that account.
BYOC security features: The maker lists multi-AZ high availability, autoscaling, load balancing, optional PrivateLink, and data sovereignty for BYOC.
Observability: The maker lists Prometheus metrics, gRPC reflection, an HTTP control plane, and a live terminal dashboard.
Automatic setup: The maker says ez-cdc can create publications, replication slots, sink tables, and audit columns automatically.
Support: The project points users to GitHub Discussions and Issues, and its documentation lists support by email or GitHub issue.
Intended users: The README describes dbmazz as an option for teams seeking streaming PostgreSQL CDC without operating a streaming platform.
Notable limitation: The README says each dbmazz instance handles one replication job.
