class TriangleCount extends Arguments with Serializable with WithIntermediateStorageLevel
Triangle count implementation.
This class provides two algorithms for counting triangles:
- A direct version that computes exact triangle counts using set intersection of neighbor lists.
- An approximate version based on the DataSketches library (Theta sketches), which trades off accuracy for performance on large-scale graphs.
The output DataFrame contains two columns:
- "id": the vertex id
- "count": the number of triangles passing through the vertex
