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

> 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.

> INSERT INTO console
