iQCAR: inter-Query Contention Analyzer for Data Analytics Frameworks

Summary: iQCAR attributes query slowdowns to concurrent queries in analytics frameworks. It builds a multi-level DAG of resource conflicts for online time-window analysis, pinpointing the most contentious queries, resources, and hosts with higher accuracy than overlap-based baselines.
