How to use the enhanced Kafka support in AAP 2.6 with multiple topics, wildcards, and improved reliability for event-driven automation.
Introduction
AAP 2.6 significantly improves Kafka integration for Event-Driven Ansible with support for multiple topics, wildcard patterns, and better error handling. This makes Kafka-driven automation more practical for real-world enterprise environments.
What's New for Kafka in AAP 2.6
Multiple Topic Support
You can now subscribe to multiple Kafka topics in a single rulebook:
Wildcard Pattern Matching
Use wildcards to subscribe to topic patterns:
This matches all topics starting with infrastructure.: • infrastructure.cpu_alerts • infrastructure.disk_warnings • infrastructure.network_events
Improved Error Handling
Enhanced connection resilience with: • Automatic reconnection on broker failures • Configurable retry logic • Better error reporting in EDA logs • Graceful handling of topic deletion
Example: Multi-Topic Event Processing
Architecture Considerations
Consumer Groups
Use consumer groups to distribute event processing across multiple EDA instances:
Topic Design
Design your Kafka topics with EDA wildcard support in mind:
Best Practices Use consumer groups for high-availability EDA deployments Design hierarchical topics to leverage wildcard subscriptions Monitor consumer lag to ensure EDA keeps up with event volume Set appropriate timeouts for rulebook actions Test with high volume before production deployment
Conclusion
Enhanced Kafka support in AAP 2.6 makes event-driven automation more powerful and practical. Multi-topic and wildcard support reduce rulebook complexity while improved error handling increases reliability.
