Tejas Patil commented on SPARK-20703:
-------------------------------------
for dynamic partitioned tables, number of partitions produced could also be a
good metric to track.
> Add an operator for writing data out

> Key: SPARK-20703
> URL: https://issues.apache.org/jira/browse/SPARK-20703
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Reynold Xin
>
> We should add an operator for writing data out. Right now in the explain plan
> / UI there is no way to tell whether a query is writing data out, and also
> there is no way to associate metrics with data writes. It'd be tremendously
> valuable to do this for adding metrics and for visibility.
