   ### Search before asking
   
   - [X] I had searched in the 
[issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22)
 and found no similar issues.
   
   
   ### What happened
   
   
测试seatunnel的同步功能时，使用http作为source，mysql作为sink。不论配不配置poll_interval_millis，都只在任务启动时同步一次数据到mysql里面，然后在任务保持任务运行状态下，post新数据后，并没有更新或插入操作，日志也显示数据条数持续不变，怀疑未进行轮询
