| Abstract(in English) | This paper presents a dynamic load balancing algorithm for right-deep pipelined hash multi-joins executed on a shared nothing architecture. The algorithm makes use of a centralized processor called the foreman to gather statistics from the processors participating in the join. With these statistics, the foreman is able to determine how the build relation tuples should be redistributed to equalize the number of result tuples remaining to be generated by each of the processors. The unit of load migration is a hash line, the set of build tuples mapped to the same hash entry in a pipeline stage's hash table, and load balancing is performed separately for each stage of the pipeline. |
