Abstract: Query optimization using of a query that is compiled into a query tree. The optimization is efficiently performed by using a distinct value estimation data structure (e.g., a KMV synopsis) that represents within an interval distinctness of values that are generated based on data within an interval, even if the resultant data from a subinterval is considered. Various candidate query trees are evaluated, with distinct value generation data structures being propagated for parent nodes based on the distinct value generation data structures of its child node(s). Propagation operations correlate to the operation represented by the parent node in the query tree. The optimizer uses the propagated distinct value estimation structure in order to evaluate the number of distinct values of data that would result from execution of the candidate query tree at least at the corresponding operations (and not just based on the distinct values of the input data).

Abstract: Shuffling of into partitions by first grouping input vertices of a limited number. Each group of input vertices may then be simply shuffled into a corresponding group of intermediate vertices, such as by broadcasting. A second grouping occurs in which the intermediate vertices are grouped by partition. The intermediate vertices then shuffle into corresponding output vertices for the respective partitions of that group. If the intermediate vertices are still too large, then this shuffling may involve recursively performing the shuffling just described, until ultimately the number of intermediate vertices shuffling into the output vertices is likewise limited. Thus, the final shuffling into the output vertices might also be simply performed by broadcasting.
