Subject [jira] [Commented] (FLINK-10975) Add support for TimeAttribute in Map/FlatMap operator
Date Mon, 25 Mar 2019 01:45:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-10975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16800347#comment-16800347
] 

sunjincheng commented on FLINK-10975:
-------------------------------------

As the Google doc mentioned, the time attribute is lost after the map/flatMap operation. e.g.:
{code}
tab('name, 'age, 'address, 'rowtime)
tab.map(udf('name)).as('col1, 'col2) // Does not include time attributes.
{code}
So, I close this JIRA. first.
