Start with the linked datatunnel Doris example at examples/src/main/kotlin/com/superior/datatunnel/examples/doris and compare its MySQL-to-Doris and Kafka-to-Doris configurations with this connector’s integration points. Confirm the intended Spark/Doris support scope and define completion through working equivalent examples or tests; the issue names no repository implementation file or test.
