------------------------------------
Summary: Create dedicated OneRowRelationExec node
Key: SPARK-52060
URL: https://issues.apache.org/jira/browse/SPARK-52060
Project: Spark
Issue Type: Task
Components: SQL
Affects Versions: 4.1.0
Reporter: Richard Chen
creates a new OneRowRelationExec node, which is more or less a copy of the
RDDScanExec node.
We want a dedicated node because this helps make it more clear when a one row
relation, i.e. for patterns like `SELECT version()` is used.
