My aim is to find whether the max path length between two vertices is <= 4.
I have a graph dataframe and a test file of the below format.
I am trying to get the output column(OP) from bfs function of graph dataframes.
Col1, Col2, OP
a1, a4, true
a2, a1, false
a3, a5, true
Currently, I am looping through each and every row and applying bfs like below
gf.bfs.fromExpr("id = 'a1'").toExpr("id = 'a4'").maxPathLength(4).run()
Are there any better approaches where I can directly plugin list of vertices at source and destination to calculate the bfs in graph frames.
