Worked on the man-group/ArcticDB repository to deliver reliability and performance improvements for column statistics generation and query statistics reporting. Focused on optimizing index-key reads by ensuring each key is read only once, which reduced CPU and I/O usage during analytics. Refactored and simplified the ColumnStats component by removing legacy code paths and dead tests, improving maintainability and reducing technical debt. Enhanced user-facing naming through safer string handling and iteration patterns using C++ and Python. The work emphasized robust testing, code cleanup, and performance optimization, resulting in lower analytics latency, more accurate statistics, and a more maintainable backend codebase.
