During October 2025, Antoine B. developed ARRAY query parameter support for the Workbench view in the apache/druid repository, enhancing the system’s ability to handle multi-valued array parameters in queries. He approached this by updating the druid-query-toolkit dependency to version 1.2.1 and ensuring license compliance, while maintaining robust test coverage through updated snapshots that reflected the new behavior. Working primarily with React, JavaScript, and TypeScript, Antoine focused on seamless UI integration and careful dependency management. His work improved parameter handling reliability in the Workbench, aligning tooling for stability and compliance without introducing regressions or reported bugs during the period.
