Jark Wu commented on FLINK-13900: --------------------------------- Hi [~xiaodao], this is one of the approaches. However, if the query has 100 columns, it is verbose to define the columns and types again in the DDL. Having a built-in sink without defining it will be helpful for debugging purpose. > Add a built-in "console" sink to print results in console > --------------------------------------------------------- > > Key: FLINK-13900 > URL: https://issues.apache.org/jira/browse/FLINK-13900 > Project: Flink > Issue Type: New Feature > Components: Table SQL / API, Table SQL / Planner > Reporter: Jark Wu > Priority: Major > > It is a useful feature for debugging and quickstart.
