Worked on Apache Arrow’s Acero module to enable implicit ordering for LIMIT queries in the Record Batch Reader Source, allowing efficient SELECT * LIMIT k operations without user-facing changes. This involved C++ development focused on data processing and unit testing, ensuring SQL compatibility and improved query planning for batch reads. In the mathworks/arrow repository, addressed reliability in asynchronous pipelines by implementing robust exception handling in AsyncTaskScheduler, preventing hangs from unhandled initial_task exceptions. Enhanced error reporting and ensured task completion, reducing the risk of production outages. The work demonstrated depth in asynchronous programming, error handling, and collaborative development across repositories.
