Abstract
Improvements to the performance of distributed database systems are described. Suggested table distributions are provided that can reduce the performance overhead associated with database operations that involve multiple nodes, and can provide more even distribution of computing resource use. A method includes minimizing a cost function that includes a plurality of performance metrics, at least a portion of the metrics being associated with a weight. Candidate table distributions can be analyzed in an iterative manner to determine a lowest-cost distribution. A final table distribution can be output, such as to a user.
