Examples with WorkerInputManager com.baidu.hugegraph.computer.core.input.WorkerInputManager used on opensource projects

Example 1 with WorkerInputManager

use of com.baidu.hugegraph.computer.core.input.WorkerInputManager in project hugegraph-computer by hugegraph.

the class WorkerService method inputstep.

/**
 * 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.
