Decomposable aggregate functions. Aggregate functions present a bottleneck, because they potentially require having all input values at once.In distributed computing, it is desirable to divide such computations into smaller pieces, and distribute the work, usually computing in parallel, via a divide and conquer algorithm.. Some aggregate functions can be computed by computing the aggregate for

A system and method include obtaining a query and identifying an aggregate join index (AJI) at a high level of aggregation. The dimension table may be rolled-up with the grouping key being the union of the grouping key in the AJI and the grouping key of the query. The identified AJI is joined with the rolled-up dimension table to obtain columns in the query that are not in the identified AJI.
