Flink输出问题之flink侧输出算子堵住如何解决

问题一：flink侧输出算子堵住的问题问题描述：(兄弟部门的问题，不方便截图，请求原谅~~) 1. flink版本： 1.6.0 2. 基本流程：flink读取kafka数据 -> json解析->(process并行度6)往下游11条pipeline发送数据 3. 问题现象：运行一段时间后，该任务堵住，sink端无数据产生 4. 监控信息：任务在map->sid...

如题，当前Flink任务反压情况下，基于Flink WebUI可以定位到反压算子C1的前一个算子B1。但是B1的后续如果有很多个算子，比如C1、C2、C3、......、Cn。如何在C1-Cn之间定位问题算子呢？总不能不断拆分任务，去除部分算子排除法吧。当前希望是通过metrics指标来看。但是，和buffer相关的指标，目前发现有很多指标恒定为0，感觉貌似是没统计，而不是实际值是0。比.....
