Argument Category Description
TargetKey Required Specifies 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 argument specifies).
EdgeWeight Optional Specifies the name of the edges table column that contains edge weights. Each edge_weight is a positive value. By default, each edge_weight is 1; that is, the graph is unweighted.
Directed Optional Specifies whether the graph is directed. The default value is 'true'.
MaxDistance Optional Specifies the maximum distance between source and target for which the function outputs the vertices. The max_distance must be an integer. If max_distance is negative, the distance between source and target is unbounded. The default is value is 10.
GroupSize Optional Specifies the number of source vertices that execute a single-node shortest path (SNSP) algorithm in parallel. If group_size exceeds the number of source vertices in a partition, then the number of source vertices in the partition is the group size. By default, the function uses cluster and query characteristics to determine the optimal group size.
