Abstract: Most of the currently existing query languages and data processing frameworks rely on one or another form of the group-by operation for data aggregation. In this paper, we critically analyze properties of this operation and describe its major drawbacks. We also describe an alternative approach to data aggregation based on accumulate functions and demonstrate how it can solve these problems. Based on this analysis, we argue that accumulate functions should be preferred to group-by as the main operation for data aggregation.
