Abstract
A computer-implemented method for partitioning data for a query operation of one table of the database system is provided. The computer-implemented method comprises estimating a value distribution of the attribute in the result table based on a first value distribution of the attribute in the first column of the first table. The computer-implemented method further comprises determining boundaries for partitioning ranges of the attribute, based on the estimated value distribution, wherein the partitioning ranges correspond to a same number of rows of the result table. The computer-implemented method further comprises partitioning the first table with processing nodes of the query operation, based on the determined boundaries of partitioning ranges.
