Comparison between GraphFrames and GraphX

It is important to look at a quick comparison between GraphX and GraphFrames as it gives you an idea as to where GraphFrames are going. Joseph Bradley, who is a software Engineer at Databricks, gave a brilliant talk on GraphFrames and the difference between the two APIs. The talk is available at http://bit.ly/2hBrDwH. Here is a summary of the comparison:

	GraphFrames	GraphX
Core APIs	Scala, Java, Python	Scala only
Programming Abstraction	DataFrames	RDDs
Use Cases	Algorithms, Queries, Motif Finding	Algorithms
VertexIds	Any type (in Catalyst)	Long
Vertex/edge attributes	Any number of DataFrame columns	Any type (VD,ED)
Return Types	GraphFrames/DataFrames	Graph [VD,ED] or ...
