类 OdevitySortByNameJobShardingStrategy

java.lang.Object

org.apache.shardingsphere.elasticjob.infra.handler.sharding.impl.OdevitySortByNameJobShardingStrategy

所有已实现的接口:

JobShardingStrategy, TypedSPI

public final class OdevitySortByNameJobShardingStrategy
extends Object
implements JobShardingStrategy

Sharding strategy which for hash with job name to determine IP asc or desc.

IP address asc if job name' hashcode is odd; IP address desc if job name' hashcode is even. Used to average assign to job server. For example: 1. If there are 3 job servers with 2 sharding item, and the hash value of job name is odd, then each server is divided into: 1 = [0], 2 = [1], 3 = []; 2. If there are 3 job servers with 2 sharding item, and the hash value of job name is even, then each server is divided into: 3 = [0], 2 = [1], 1 = [].
