Parameterize the number of iterations in the Gremlin pageRank step

Question

As far as I understand gremlin pageRank step (g.V().pageRank()) runs a PageRank vertex program with 30 iterations.

Is it possible to change the max number of iterations?

Answer 1

This should work:

g.V().pageRank().times(5)

There's an example of this in the Apache TinkerPop docs:

gremlin> g.V().pageRank().by('pageRank').times(5).order().by('pageRank').valueMap()
