Takeshi Yamamuro created SPARK-24690:
----------------------------------------
Summary: Add a new config to control plan stats computation in
LogicalRelation
Key: SPARK-24690
URL: https://issues.apache.org/jira/browse/SPARK-24690
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.3.1
Reporter: Takeshi Yamamuro
We cannot currently enable StarSchemaDetection.reorderStarJoins because we need
to turn off CBO to enable it but StarSchemaDetection internally references
LogicalPlan.stats.rowCount.
This rowCount is used in LogicalRelation if CBO disabled.
This ticket is to propose a new separate config so that LogicalRelation can use
rowCount to compute data statistics.
