What it does
Earlier this week, we launched PeerDB Streams , our latest product offering for real-time replication from Postgres to queues and message brokers such as Kafka , Redpanda , Google PubSub , Azure Event Hubs , and others. Today, we are announcing one of the flagship features of this offering — support for row-level transformations as part of Postgres Change Data Capture (CDC). You can write simple Lua scripts to define a transformation and add it as part of the replication (MIRROR). With this feature, users will be able to seamlessly perform in-flight row-level transformations to Postgres data before it is streamed to the target.

Hey HN, I’m an engineer at Supabase [0] and one of the creators of this demo. My team and I have been working hard to bring developers the next version of Supabase Realtime. The current version of Realtime [1] is a Change Data Capture (CDC) server for a PostgreSQL database that broadcasts changes via WebSockets to authorized subscribers. It’s written in Elixir/Phoenix. The server utilizes PostgreSQL’s logical replication functionality, which writes database changes to Write-Ahead Logging (WAL) segment files, and a replication slot, responsible for managing and retaining WAL files.…
