Integration testing is crucial for Kafka Connectors to ensure they work correctly with external systems. This guide provides a comprehensive approach to setting up and executing integration tests for Kafka Connectors, covering everything from environment setup to best practices for testing source and sink connectors.
Apache Kafka is a powerful distributed event streaming platform, and Kafka Connect makes it easy to integrate Kafka with external systems. While many pre-built connectors exist, real-world applications often need custom connectors tailored for proprietary systems, custom logic, or advanced error handling. That’s where this production-ready template comes in—it removes the boilerplate and gives you everything you need to build, test, and deploy connectors with ease.
Kafka Connect provides a flexible way to process streaming data using Single Message Transforms (SMTs). If you need to filter out tombstone records (records with null values), you should use the generic Filter transformation along with the RecordIsTombstone predicate.
