Change Data Capture Node in IBM App Connect
In this blog, we will learn how to change the data capture node in IBM App Connect.
Introduction
Modern digital ecosystems require instantaneous data synchronization across applications, yet conventional approaches frequently degrade system responsiveness. Repeatedly polling relational databases for updates consumes excessive infrastructure capacity and introduces performance bottlenecks. The Change Data Capture (CDC) feature—launched in IBM App Connect Enterprise (ACE) eliminates this inefficiency by converting database mutations into low-latency event streams. By reading native transaction logs rather than executing resource-intensive query operations, the CDC node detects record additions, modifications, or deletions as they happen, immediately broadcasting standardized JSON payloads to downstream consumers without overhead on primary workloads.
Configuration Steps:
- Define the tables that you want to monitor with the CDC node in your database
- Download the required CDC connector JAR files (debezium-connector-mysql) that match your App Connect Version.
- Drag the CDC node from the App Connect palette
- Associate these credentials with the designated CDC resource name.
- Create a new Change Data Capture Policy inside an ACE Policy Project.
- Configure the connection details (database host, port, database name, and security identity).
- In the node’s Properties view, assign the CDC Policy created in the previous step.
- Specify the schema and populate the Database Tables list property with the specific table names you want to monitor.
Conclusion
Change Data Capture (CDC) in IBM App Connect Enterprise is an easy and efficient way to keep data synced across systems in real time. Instead of constantly checking the database for updates, ACE listens directly to background database logs to capture changes as soon as they happen. This means zero lag and no extra burden on your database performance. By using simple CDC policies, you can build reliable data pipelines that keep all your applications automatically updated.
