             Summary: Add a cbo conf to switch between default statistics and cbo estimated statistics
                 Key: SPARK-18998
                 URL: https://issues.apache.org/jira/browse/SPARK-18998

          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: Zhenhua Wang


We need a cbo configuration to switch between default stats and estimated stats. We also need a new statistics method in LogicalPlan with conf as its parameter, in order to pass the cbo switch and other estimation related configurations in the future.
