PeerDB
PeerDB is an open-source data movement engine built for Postgres. It streams a Postgres database into ClickHouse (and other warehouses and queues) with change data capture, so your analytics copy stays seconds behind production instead of a nightly dump behind it. You create peers and mirrors from a web UI or from plain SQL over the Postgres wire protocol.
Disclosure: deploy links carry the author's Railway referral code — the author receives a usage kickback when you deploy. The template itself is free to deploy; Railway usage charges apply.
