Postgresql

Set up a Change Data Capture architecture on Azure using Debezium, Postgres and Kafka was a tutorial on how to use Debezium for change data capture from Azure PostgreSQL and send them to Azure Event Hubs for Kafka - it used the wal2json output plugin.

What about the pgoutput plugin?

This blog will provide a quick walk through of how to pgoutput plugin and provide clarification on this point raised by Denis Arnaud (thank you for brining it up!)

Change Data Capture (CDC) is a technique used to track row-level changes in database tables in response to create, update and delete operations. Different databases use different techniques to expose these change data events - for example, logical decoding in PostgreSQL, MySQL binary log (binlog) etc. This is a powerful capability, but useful only if there is a way to tap into these event logs and make it available to other services which depend on that information.
