- TargetKey
- Specify the target key (the names of the Edges table columns that identify the target vertex). If you specify targets_table, then the function uses only the vertices in targets_table as targets (which must be a subset of those that this syntax element specifies).
- Directed
- [Optional] Specify whether the graph is directed.
- EdgeWeight
- [Optional] Specify the name of the Edges table column that contains edge weights. The weights are positive values.
- MaxDistance
- [Optional] Specify the maximum distance (an integer) between the source and target vertices. A negative max_distance specifies an infinite distance. If vertices are separated by more than max_distance, the function does not output them.
- GroupSize
- [Optional] Specify the number of source vertices that execute a SNSP algorithm in parallel. If group_size exceeds the number of source vertices in each partition, s, then s is the group size.
- SampleRate
- [Optional] Specify the sample rate (the percentage of source vertices to sample), a DOUBLE PRECISION value in the range (0.0, 1.0]. The number of source vertices that the function uses to create betweenness is approximately sample_rate*n, where n is the number of vertices in the graph.
- Accumulate
- [Optional] Specify the names of the Vertices table columns to copy to the output table. These columns enable you to identify the different betweenness scores in the output table.
