MapComp: A Secure View-based Collaborative Analytics Framework for Join-Group-Aggregation
<|reference_start|>MapComp: A Secure View-based Collaborative Analytics Framework for Join-Group-Aggregation: This paper introduces MapComp, a novel view-based framework to facilitate join-group-aggregation (JGA) queries for collaborative analytics. Through specially crafted materialized view for join and novel design of group-aggregation (GA) protocols, MapComp removes duplicated join workload and expedites subsequent GA, improving the efficiency of JGA query execution. To support continuous data updates, our materialized view offers payload-independence feature and brings in significant efficiency improvement of view refreshing with free MPC overhead. This feature also allows further acceleration for GA, where we devised multiple novel protocols that outperform prior works. Notably, our work represents the first endeavor to expedite secure collaborative JGA queries using materialized views. Our experiments demonstrate a significant advantage of MapComp, achieving up to a 2189.9x efficiency improvement compared to the non-view based baseline when executing queries eight times.<|reference_end|>
