I'm building an simple Graph with GraphFrames on Scala 2.11 Spark 2.2.
I can create my graph without problems, but i have no idea how create a subgraph from input user.
I want to extract graph from the big one, like :
Get subgraph from node#123 with 3 max depth parents.
I tried connectedComponent, ( see https://graphframes.github.io/user-guide.html ) but I have no idea what to do with "compenent" column.
Thanks for your helps.
