The output table has a row for each source vertex. The reachable target vertices exclude the source vertex itself; that is, the function does not calculate the closeness and k-degree scores for loops.
| Column | Data Type | Description |
|---|---|---|
| inv_sum_dist | DOUBLE PRECISION | Inverse of the sum of the shortest distances to all reachable target vertices. If there are no reachable target vertices, then this value is NULL. |
| inv_avg_dist | DOUBLE PRECISION | Inverse of the average shortest distances to all reachable target vertices. If there are no reachable target vertices, then this value is NULL. |
| sum_inv_dist | DOUBLE PRECISION | Sum of the inverse distances to all reachable target vertices. If there are no reachable target vertices, then this value is NULL. |
| kdegree | DOUBLE PRECISION | Total number of reachable target vertices. If there are no reachable target vertices, then this value is 0. |
| accumulate_column | Same as in vertex table | Column copied from the vertex table. The table can have more than one such column. These columns enable you to identify different closeness scores. |
