Summary: Wire SQLConf in logical plan and expressions
Key: SPARK-21092
URL: https://issues.apache.org/jira/browse/SPARK-21092
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 2.2.0
Reporter: Reynold Xin
Assignee: Reynold Xin
It is really painful to not have configs in logical plan and expressions. We
had to add all sorts of hacks (e.g. pass SQLConf explicitly in functions). This
ticket exposes SQLConf in logical plan, using a thread local variable and a
getter closure that's set once there is an active SparkSession.
