类 FailbackLogPositionManager

java.lang.Object

com.alibaba.otter.canal.common.AbstractCanalLifeCycle

com.alibaba.otter.canal.parse.index.AbstractLogPositionManager

com.alibaba.otter.canal.parse.index.FailbackLogPositionManager

所有已实现的接口:

CanalLifeCycle, CanalLogPositionManager

public class FailbackLogPositionManager
extends AbstractLogPositionManager

Created by yinxiu on 17/3/18. Email: marklin.hz@gmail.com 实现基于failover查找的机制完成meta的操作

 应用场景：比如针对内存buffer，出现HA切换，先尝试从内存buffer区中找到lastest position，如果不存在才尝试找一下meta里消费的信息
