Specify the target key columns in the edges table.
EdgeWeight
[Optional] Specify the column in the edges table that contains the edge weight, which must be a positive value.
Default behavior: All edges have the same weight (that is, the graph is unweighted).
DampFactor
[Optional] Specify the value to use in the PageRank formula. The damp_factor must be a DOUBLE PRECISION value between 0 and 1.
Default: 0.85
MaxIterNum
[Optional] Specify the maximum number of function iterations before the function completes. The max_iterations must be a positive INTEGER value.
The max_iterations is the number of function iterations (that is, the SQL-GR iterations minus 3).
Default: 20
StopThreshold
[Optional] Specify the convergence criteria value. The threshold must be a DOUBLE PRECISION value.
Default: 0.0001
Accumulate
[Optional] Specify the vertices table columns to copy to the output table.
