[jira] [Commented] (FLINK-13900) Add a built-in "console" sink to print results in console

["Timo Walther (Jira)" <ji...@apache.org>]

Timo Walther commented on FLINK-13900:
--------------------------------------

In general this would be useful, but it would be the first sink that has no fixed expected schema right? Have you considered adding it as a regular connector that can be used in DDL etc. with maybe additional options?

> It is a useful feature for debugging and quickstart. With the console builtin sink, we can directly output arbitrary query into the console or {{taskmanager.out}} in cluster setup. 
> Currently, we have to implement a dedicate PrintTableSink and configure every field names and types before output the query, which is very verbose.
