---------------------------------------
Summary: explain function with codegen and cost parameters
Key: SPARK-22044
URL: https://issues.apache.org/jira/browse/SPARK-22044
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.2.0
Reporter: Jacek Laskowski
Priority: Minor
{{explain}} operator creates {{ExplainCommand}} runnable command that accepts
(among other things) {{codegen}} and {{cost}} arguments.
There's no version of {{explain}} to allow for this. That's however possible
using SQL which is kind of surprising (given how much focus is devoted to the
Dataset API).
This is to have another {{explain}} with {{codegen}} and {{cost}} arguments,
i.e.
{code}
def explain(codegen: Boolean = false, cost: Boolean = false): Unit
{code}
