Research direction

Start by examining existing connectors in the SeaTunnel repository (e.g., connectors/connector *) to understand the structure and patterns. Review the Fluss project documentation and API at https://github.com/alibaba/fluss to identify how to integrate as a source and sink. Check if there are any previous discussions in the issue comments (5 comments) for additional context. Implement the connector module, then add documentation in both English and Chinese under the docs directory, and finally add end to end tests following the existing E2E test patterns.
