链路监控
以前的方案
全量校验，逻辑上就是select * from tcbuyer.order的结果，和select * from tc.order 的结果作对比。
伪增量校验 ，比较上一个小时的数据。
单流增量校验， 基于事件的比较，当买家库生成一笔订单后，相应地MySQL会产生一条binlog，单流增量校验系统就能以这条binlog作为触发条件，解析出binlog内容，去实时反查卖家库有没有对应记录。
AMG的校验图模型——Check Graph
假设交易链路有4个业务系统需要对账，分别是交易、库存、资金和支付，其中涉及的事件分别对应 交易下单事件、减库存事件、使用红包资金事件、支付事件。对账的需求如下：
交易事件 和 库存事件 做校验；
交易事件 和 资金事件 做校验；
交易事件 和 支付事件 做校验；
资金事件 和 支付事件 做校验。
一旦上面4个校验中的其中一个出现问题，都认为是业务系统存在异常，需要及时报出来。
明显可以看出来，这是一个图模型。比如，A事件和B事件校验，则存在一条边，连接A和B点。以事件作为点（Node），事件间的校验方法作为边（Edge），构造出一个图（Graph）模型。按照上述场景，构造的图模型如下：
交易 《-----校验----》
集团的各个系统为了业务解耦、保证主链路的性能或可用性，各系统之间常常存在各种同步异步调用、强弱依赖关系。一旦网络抖动、业务系统bug、或是某个子系统出现异常，就可能就会出现业务数据不一致。拿最核心的交易系统和库存系统来说，用户下了单之后，没减库存，那么很有可能出现超卖；用户关闭订单之后，没有回补库存，那么就会导致少卖。这就是交易和库存系统之间的数据不一致。
