In January 2026, Ghafek integrated the Star Schema Benchmark (SSB) into the apache/systemds repository to support performance evaluation and benchmarking. He developed a suite of DML queries and Shell runner scripts that automate the benchmarking process, enabling standardized and repeatable performance assessments for SystemDS. His work established a framework that informs both optimization and capacity planning by providing consistent performance data. Throughout the project, Ghafek applied skills in data analysis, data processing, and performance benchmarking, focusing on automation and version control. The depth of the implementation provided a solid foundation for ongoing performance evaluation, though no major bugs were addressed.
January 2026: Key feature delivered was the Star Schema Benchmark (SSB) Integration for SystemDS performance evaluation. This included multiple DML queries and runner scripts to enable automated benchmarking. No major bugs fixed this month. Overall impact: established a standardized, repeatable benchmarking framework that informs performance optimization and capacity planning. Skills demonstrated: benchmarking architecture, DML query design, scripting/automation, and version control.
