在 flink job 运行一段时间后,观察日志发现出现了如下的 warn日志:
The operator name {} exceeded the {} characters length limit and was truncated
完整的 warn 日志如下:
The operator name TriggerWindow(GlobalWindows(), ListStateDescriptor{name=window-contents, defaultValue=null, serializer=org.apache.flink.api.common.typeutils.base.ListSerializer@a953d288}, PurgingTrigger()) exceeded the 80 characters length limit and was truncated.
修复方式:可以忽略,仅仅表示在flink web ui 上不会显示完整的 SQL。
