zhuangchong opened a new issue #3334: URL: https://github.com/apache/incubator-dolphinscheduler/issues/3334
**Describe the feature** Query the database log table ID and judge that the last task is completed. If the execution is not completed, set the next query interval. **Is your feature request related to a problem? Please describe.** For the following reasons, add wait table plug-ins 1. Traditional ETL tasks are connected through the database log table identification, and the current task node judges whether the previous task node is completed. 2. A way of docking between departments or project groups and tasks, because it can not guarantee that DS can be used in the whole company. (currently DS supports API call mode, but it is not comprehensive, so database log table identification method can be considered). At present, we are confronted with this problem. Only we use DS ourselves. The traditional existing methods are connected with DS tasks of big data, and task docking between project teams. **Describe the solution you'd like**  --- **描述功能** 查询数据库日志表标识，判断上一个任务十分执行完成。如未执行完成，设置下次查询时间间隔。 **您的功能请求是否与问题相关？请描述一下** 基于以下几点原因，新增 插件 1.传统ETL 任务之间对接，都是通过数据库日志表标识，当前任务节点判断上一个任务节点是否执行完成。 2.部门或项目组之间，任务之间对接的一种方式，因为并不能保证DS可以在全公司内使用.（目前DS支持API调用方式，但是并不全面，可以考虑数据库日志表标识方式）。 目前我们这就遇到这个问题，只有我们自己使用，传统已有方式和大数据DS任务对接，项目组之间任务对接。  ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
