—Interactive ad-hoc analytics over large datasets has become an increasingly popular use case. We detail the challenges encountered when building a distributed system that allows the interactive exploration of a data cube. We introduce DICE, a distributed system that uses a novel session-oriented model for data cube exploration, designed to provide the user… (More)
The interactive exploration of data cubes has become a popular application , especially over large datasets. In this paper, we present DICE, a combination of a novel frontend query interface and distributed aggregation backend that enables interactive cube exploration. DICE provides a convenient, practical alternative to the typical offline cube… (More)
