DQSim: Does the Task Assignment Slow Down Your Distributed Database System?
Summary: DQSim formalizes distributed task scheduling and simulates query execution, enabling rapid evaluation of schedulers without modifying a database system. Its NetHEFT and cCEFT algorithms cut latency by over 2× in challenging scenarios. (summarized by gpt-6-luna on Oct 22 2026)
