Lifei Chen commented on FLINK-7464: ----------------------------------- Hi, [~sunjincheng121], I think `FIRST_VALUE` and `LAST_VALUE` are very useful and I can also find the two build-in aggregate functions docs of [aliyun|[https://help.aliyun.com/knowledge_detail/62791.html]]. But the subtask is closed with status unsolved. is there any reasons why the progress of the feature is stopped ?
