E-Cube: Multi-Dimensional Event Sequence Analysis Using Hierarchical Pattern Query Sharing
Summary: Proposes E-Cube, a multi-dimensional event-pattern model that fuses CEP and OLAP for real-time pattern analysis over streams. Leverages hierarchical query sharing with drill-down/roll-up and the cost-driven optimizer Chase to reuse intermediates, delivering up to tenfold speedups on stock-market workloads.
