> when the size of the graph is huge(0.2 billion vertex, 6 billion edges), the srcAttr and dstAttr in graph.triplets don't update when using the Graph.outerJoinVertices(when the data in vertex is changed).
> the code and the log is as follows:
> {quote}
> g = graph.outerJoinVertices()...
> g,vertices,count()
> g.edges.count()
> println("example edge " + g.triplets.filter(e => e.srcId == 5000000001L).collect()
>       .map(e =>(e.srcId + ":" + e.srcAttr + ", " + e.dstId + ":" + e.dstAttr)).mkString("\n"))
>     println("example vertex " + g.vertices.filter(e => e._1 == 5000000001L).collect()
>       .map(e => (e._1 + "," + e._2)).mkString("\n"))
> {quote}
> the result:
> {quote}
> example edge 5000000001:0, 2467451620:61
> 5000000001:0, 1962741310:83 // attr of vertex 5000000001 is 0 in Graph.triplets
> example vertex 5000000001,2 // attr of vertex 5000000001 is 2 in Graph.vertices
> {quote}
> when the graph is smaller(10 million vertex), the code is OK, the triplets will update when the vertex is changed
