Debugging Edges
Debugging edges means recording of data flowing through the edge for further inspection.
Debugging is useful if you obtain incorrect or unexpected results after running a graph, as it helps you locate and identify the errors in the graph.

If you process a large amount of data, consider limiting the number of records to be saved into debug files or to filter the data. |
By default, debugging is enabled on all edges.
There are several debugging options for each edge. Right-click on the edge and select the Debug option from the context menu:

After you run the graph, one debug file is created for each debugged edge.
