Method Detail

getWorkerCount

int getWorkerCount()

Get number of workers

Returns:

Number of workers

getTotalNumVertices

@Deprecated
long getTotalNumVertices()

Deprecated.

Get the total (all workers) number of vertices that existed at the start of the current piece. Recommended to avoid it, as it introduces global dependencies, code will not be able to work on top of a subgraphs any more. This number should be easily computable via reducer or aggregator.

getTotalNumEdges

@Deprecated
long getTotalNumEdges()

Deprecated.

Get the total (all workers) number of edges that existed at the start of the current piece. Recommended to avoid it, as it introduces global dependencies, code will not be able to work on top of a subgraphs any more. This number should be easily computable via reducer or aggregator.
