[jira] [Commented] (FLINK-7464) Add useful build-in Aggregate
function into TabalAPI&SQL
[ https://issues.apache.org/jira/browse/FLINK-7464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16812283#comment-16812283 ]
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 ?
Thanks !
