-----------------------------------
Summary: 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.
