We have to decide the schema of a UDTF at the run time. For example. udtf('c1, c2, c3') will generate three columns for a lateral view. Most systems such as calcite and hive support this feature. However, the current implementation of flink didn't implement the feature correctly. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
