Abstract
A system includes determination of a first partition-wise operation on a first database table partition of a first table located at a first server node and a first database table partition of a second table located at a second server node, determination of a first cost to execute the first partition-wise operation on the first server node, and a second cost to execute the first partition-wise operation on the second server node, determination of a second partition-wise operation on a result of the first partition-wise operation, determination of a third cost to execute the second partition-wise operation on the first server node based on the first cost and the second cost, and a fourth cost to execute the second partition-wise operation on the second server node based on the first cost and the second cost, determination of one of the first server node and the second server node to execute the second partition-wise operation based on the third cost and the fourth cost, and determination of one of the first server node and the second server node to execute the first partition-wise operation based on the third cost and the fourth cost.
