Example 6 with SuperstepStat

use of com.baidu.hugegraph.computer.core.graph.SuperstepStat in project hugegraph-computer by hugegraph.

the class MasterService method inputstep.

/**
 * Coordinate with workers to load vertices and edges from HugeGraph. There
 * are two phases in inputstep. First phase is get input splits from
 * master, and read the vertices and edges from input splits. The second
 * phase is after all workers read input splits, the workers merge the
 * vertices and edges to get the stats for each partition.
