adaptive execution in Spark SQL
URL: https://github.com/apache/spark/pull/24706#issuecomment-501611416
 
 
   I just ran the following script
   ```
       withSQLConf(
           SQLConf.RUNTIME_REOPTIMIZATION_ENABLED.key -> "true",
           SQLConf.AUTO_BROADCASTJOIN_THRESHOLD.key -> "80") {
         spark.sql(
           "SELECT * FROM testData join testData2 ON key = a where value = 
'1'").show(false)
         Thread.sleep(100000000)
       }
   ```
   
   In the details of SQL Tab, the plan has been changed to broadcast join, but 
the value of `isFinalPlan` is still false and the codegen id is wrong.
