Abstract

Aspects include operating a distributed database that includes multiple computing nodes that are connected via a network for exchanging data, and a database management system for managing a source dataset and a target dataset. The target dataset is stored in a distributed fashion across the multiple computing nodes. The method includes repeatedly, using the multiple computing nodes, checking for a matching condition between a source element selected from a source dataset and one of multiple target elements in the target dataset. The multiple computing nodes are used to calculate a command set of a merged command list of commands to merge the source element with the target element using the matching condition. The command set is executed to merge the source element with the target dataset before checking for the matching condition between a next source element selected from the multiple source element and one of the multiple target elements.
