Specifies the target key (the names of the edges table columns that identify the target vertex). If you specify targets_table, the function uses only the vertices in targets_table as targets (which must be a subset of those that this argument specifies).
[Optional] Specifies the name of the edges table column that contains edge weights. Each edge_weight is a positive value. Default: Each edge_weight is 1; that is, the graph is unweighted.
[Optional] Specifies whether the graph is directed. Default: 'true'.
[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. Default: 10.
[Optional] Specifies the number of source vertices that run a single-node shortest path (SNSP) algorithm in parallel. If group_size exceeds the number of source vertices in a partition, the number of source vertices in the partition is the group size. Default behavior: The function uses cluster and query characteristics to determine the optimal group size.
