   wait, it seems the query works well in v2.4.3;
   ```
   scala> df.explain
   == Physical Plan ==
   *(1) Range (0, 10, step=1, splits=4)
   
   scala> df.persist
   res1: df.type = [id: bigint]
   
   scala> df.explain
   == Physical Plan ==
   *(1) InMemoryTableScan [id#0L]
      +- InMemoryRelation [id#0L], StorageLevel(disk, memory, deserialized, 1 replicas)
            +- *(1) Range (0, 10, step=1, splits=4)
   scala> 
   ```
   Which commit affects the behaviour?
