TargetKey
Specifies the names of the columns in the edges table that identify the target vertex of an edge. This set of columns must have the same schema as the vertex_attributes and source_vertex_attributes.
SampleRate
[Optional] Specifies the sampling rate. This value must be in the range (0, 1.0). Default: 0.15 (15%).
FlyBackRate
[Optional] Specifies the chance, when visiting a vertex, of flying back to the starting vertex. This value must be in the range (0, 1.0). Default: 0.15 (15%).
Seed
[Optional] Specifies the seed used to generate a series of random numbers for sample_rate, flyback_rate, and any random number used internally. Specifying this value guarantees that the function result is repeatable on the same cluster. Default: 1000.
OutputTables
Specifies the names of the vertex and edge tables.
Accumulate
[Optional] Specifies the names of columns in the input vertex table (vertices) to copy to the output vertex table (vertex_table).
