What are the various operators in PySpark GraphX?
Property Operators : These operators create a new graph with a user-defined map function modifying the characteristics of a vertex or edge. For these operators, the graph structure is unchanged. This is an important property of these operators because it allows the generated graph to preserve the structural indices of the original graph.
Structural Operators : GraphX currently supports only a few widely used structural operators. The opposite operator creates a new graph with the directions of the edges reversed. The subgraph operator returns a graph with only vertices and edges that meet the vertex predicate. The mask operator creates a subgraph by returning a graph with all vertices and edges found in the input graph. The groupEdges operator merges parallel edges.
Join operators : Join operators allow you to join data from external collections (RDDs) to existing graphs. For example, we may want to combine new custom attributes with an existing graph or drag vertex properties from one graph to another.
