🎄Twelve Days of SMT 🎄 - Day 3: Flatten 

The `Flatten` Single Message Transform (SMT) is useful when you need to collapse a nested message down to a flat structure.
This video explains using the Flatten SMT when streaming nested data to a database (MySQL in this case) with the JDBC Sink connector.
Kafka Connect is the primary method for doing integration with Apache Kafka and other systems. It includes Single Message Transform (SMT) which can be used to modify messages as they pass through the pipeline in or out of Kafka.
