Hi Hangxiang,
感谢您的回应。
下面是该问题的关键代码,main_stream表是流数据源,数据事件流频约每笔500ms~1s,目前尝试将t1minStream和t5minStream
assignTimestampsAndWatermarks(WatermarkStrategy.noWatermarks())是不会产生这问题造成作业失败了,但输出会有数据丢失。
如有其他思路,麻烦你了。
String t1minSql = "SELECT rowtime, key, id, AVG(num) OVER w_t1min AS avg_t1min
FROM main_stre
Hi,
可以通过设置 table.exec.state.ttl 来控制状态算子的 state TTL. 更多信息请参阅 [1]

在使用使用jemalloc内存分配器一段时间后,出现checkpoint
超时,任务卡住的情况,哪位遇到过呢?flink版本:flink-1.13.2,jiemalloc版本:5.3.0
After using the jemalloc memory allocator for a period of time, checkpoint
timeout occurs and tasks are stuck. Who has encountered this? flink
version:1.13.2, jiemalloc version: 5.3.0
请教一下,flink的两阶段提交对于sink算子,预提交是在做检查点的哪个阶段触发的?预提交时具体是做了什么工作?
