Lakebase change data feed
Every insert, update and delete in a Lakebase schema written to Unity Catalog Delta history tables, read from the Postgres write-ahead log.
Why it is worth watching
It is the built-in route from operational Postgres to the lakehouse: no CDC tool, no message bus, no replication slot to watch.
