  • Consult the logs for error message details and troubleshooting.
  • The logs can help determine the time taken for each iteration. If you know the number of iterations that the function takes (usually 25-50), you can estimate the total execution time.
  • All graph functions operate much faster on INTEGER and BIGINT single-column vertex ids. To generate an INTEGER vertex based graph, see Tips section above.
  • Compute the modularity in incremental steps by choosing a subset of nodes using the Sources argument.
  • If you know some groupings in the graph, specify them with the CommunityAssociation argument.
  • If you specified the CommunityEdgeTable argument, the reason for slowness might be that the function is writing the community table to the database through JDBC. Run the function without the CommunityEdgeTable argument first, to obtain the modularity of the resultant graph.
