PROFILE
Kang Myeong Gwan
Over four months, contributed to the apache/seatunnel project by developing and enhancing core connector features and improving documentation accuracy. Delivered a recursive file scan option for FTP, HDFS, and local connectors, enabling configurable directory traversal and more flexible file ingestion. Enhanced the Replace Transform to support multi-field replacements, updating Java-based transformation logic while maintaining backward compatibility. Addressed documentation issues by correcting data type mapping headers and fixing Markdown formatting, reducing user confusion and aligning with project standards. Demonstrated skills in Java, data transformation, file handling, and documentation, with a focus on maintainability, configuration-driven design, and collaborative version-controlled workflows.

Jun 1, 2026June 2026 monthly summary for apache/seatunnel: Implemented a new recursive_file_scan option for file connectors (FTP, HDFS, local) to control whether subdirectories are scanned during ingestion. Default behavior remains recursive, with opt-out provided by setting recursive_file_scan to false, delivering more flexible and efficient file ingestion across connector types. No major bugs fixed this month; focus on feature delivery, code quality, and documentation. This enhancement reduces manual configuration, enables scalable ingestion of large directory trees, and strengthens our File Connector V2 capabilities. Technologies demonstrated include the Java-based connector framework, configuration-driven behavior, feature flag patterns, and cross-team collaboration on the File Connector V2 effort, reinforcing reliability and maintainability.

Feb 1, 2025February 2025 (2025-02) monthly summary focused on documentation quality improvements for the apache/seatunnel project. Delivered a targeted fix to ensure accurate data type mappings guidance in SeaTunnel connector docs by correcting the header from 'Orc Data Type' to 'Parquet Data Type' in OssFile.md and S3File.md. This doc-only change clarifies Parquet vs Orc data type mappings, reducing potential misconfigurations for users and lowering support friction.
