Stores the locations of edge-partition join sites for each vertex attribute in a particular vertex partition.
怎么翻譯？
現在把原始碼貼出來如下：
/**
* Stores the locations of edge-partition join sites for each vertex attribute in a particular
* vertex partition. This provides routing information for shipping vertex attributes to edge
* partitions.
*/
private[graphx]
class RoutingTablePartition(
private val routingTable: Array[(Array[VertexId], BitSet, BitSet)]) extends Serializable {
/** The maximum number of edge partitions this `RoutingTablePartition` is built to join with. */
val numEdgePartitions: Int = routingTable.size
/** Returns the number of vertices that will be sent to the specified edge partition. */
def partitionSize(pid: PartitionID): Int = routingTable(pid)._1.size
/** Returns an iterator over all vertex ids stored in this `RoutingTablePartition`. */
def iterator: Iterator[VertexId] = routingTable.iterator.flatMap(_._1.iterator)

就是一個路由表項的組成。頂點ID，磁區號i，j......uj5u.com熱心網友回復：
能否給出完整的翻譯？我理解的是頂點按照取模等隨機方式分到某個號（該號代表行號或列號，根據方向確定屬于哪個），比如分為3行3列，共9個區，假如一個邊的兩點中，起始點分到2，終止點去到0，那么就磁區就是（2,0），就是第四個磁區。但是這句英文怎么來翻譯呢？轉載請註明出處，本文鏈接：https://www.uj5u.com/qita/79998.html
