The input rows are arranged into groups having the same values of the by expressions. The shuffle strategy query shares the query load on cluster nodes, where each node will process one partition of the data. The shufflekey query shares the query load on cluster nodes, using a key to partition data. Specifies the number of partitions used to share the query load on cluster nodes.
