Can you explain a bit more what the general goal of this task is? Especially the formula that determines whether or not two rows match each other. Maybe there’s an easier way to solve your problem, cross-joins are very expensive and should be avoided if possible.
Maybe you can also share your workflow? It seems like you managed to make some progress already, it would be helpful to see it. If your data is sensitive, that’s fine, just fill in dummy data instead. You can export workflows by right-clicking on them in the KNIME Explorer.
