Best, SunJincheng > Refactoring UDTF interface > -------------------------- > > Key: FLINK-6334 > URL: https://issues.apache.org/jira/browse/FLINK-6334 > Project: Flink > Issue Type: Improvement > Components: Table API & SQL > Reporter: Ruidong Li > Assignee: Ruidong Li > > The current UDTF leverages the table.join(expression) interface, which is not > a proper interface in terms of semantics. We would like to refactor this to > let UDTF use table.join(table) interface. Very briefly, UDTF's apply method > will return a Table Type, so Join(UDTF('a, 'b, ...) as 'c) shall be viewed as > join(Table) -- This message was sent by Atlassian JIRA (v6.3.15#6346)
