Topics represent Kafka topics in your cluster. Go to the Settings > Topics page to view the Kafka topics available in DetectFlow.
DetectFlow automatically discovers topics in Kafka and shows their associations with Pipelines. On this page, you should be able to see all your Kafka topics. If that's not the case, ensure the Kafka permissions provided during the deployment are sufficient.
For each topic, you can see:
Topic Name. Kafka topic identifier
Pipelines. Associated Pipelines using this topic as a source or destination. If the topic is not used in a Pipeline, a dash is displayed.
Topics are used in:
Pipeline Configuration – As source and Destination Topics
Log Source Testing – As test Topics for parsing scripts
Dashboard Visualization – Displayed in the Pipeline graph
Topics must exist in Kafka before they can be used in Pipelines. If you add/update/remove a topic in Kafka, DetectFlow reflects these changes automatically. Alternatively, you can click the Sync Topics button to force-check for updates on the Kafka side.
