系统作业(逻辑名称asyncoperation)这个实体存储了工作流、异步SDK插件步骤的运行记录，若是不及时删除的话，这个实体记录数太多会严重影响系统性能。
所以我们一般做法分成两种，一个是建立一个系统批量删除作业，删除状态为成功、失败、已取消，且创建日期为X个月之前的记录(因为不少公司对日志保留有要求，起码保留一个月)，这个批量删除作业最频繁可以每隔七天运行一次。
另外一个就是切记两个选项要选中，一个是工作流的【自动删除已完成的工作流作业(以节省磁盘空间)】要选中。
另一个就是SDK插件步骤的【Delete AsyncOperation if StatusCode = Successful】要选中。
这两个选项如果不选中，有时候会带来严重问题，比如说SDK插件步骤，注册在所有实体的RetrieveMutiple，Retrieve等运行非常频繁的消息上，那带来的系统作业记录会非常多，可能一天几百万。
难道每次都一个个用眼睛看手工检查，太Low，我们当然有程序办法，跑一下程序就可以检查出来，下面就是可以参考的代码。
