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.
