Contributed to the apache/seatunnel project by enhancing the MaxCompute connector, focusing on both reliability and secure access. Addressed data processing challenges by implementing a more robust split distribution strategy, ensuring unique split IDs and correct index allocation across multiple readers. Expanded test coverage using Java and unit testing to validate these improvements, particularly in multi-reader and secure-access scenarios. Introduced schema-name based access and enabled passwordless authentication through environment variables and ECS RAM roles, streamlining secure integration with cloud environments. The work combined API development, cloud computing, and data engineering skills to improve maintainability and flexibility within the connector’s architecture.
