"Write Once Stream Everywhere: Transforming Your Data into Events"
summary
Database writes emit events via change data capture, using Postgres logical replication and a replication slot to stream WAL records so inserts/updates/deletes appear instantly in a consumer stream. The demo shows an app inserting rows and a listener receiving them with LSN positions for ordering and replay. Options covered include the open-source deum plus an outbox pattern and a hosted Prisma Pulse that stores high-throughput events with resumable delivery.
