maropu commented on issue #24960: [SPARK-28156][SQL] Self-join should not miss 
cached view
URL: https://github.com/apache/spark/pull/24960#issuecomment-507511937
 
 
   (This might be off-topic and this is just a question though...) btw, any 
reason not to use optimized plans instead of analyzed plans for plan caches? 
Just to avoid overheads? In case that we do so, it seems self-joins in the 
description uses the cached view;
   ```
   == Optimized Logical Plan ==
   Project [a#37, b#38]
   +- Join Inner, (a#37 = a#73)
      :- Project [a#37, b#38]
      :  +- Filter isnotnull(a#37)
      :     +- InMemoryRelation [a#37, b#38, c#39, d#40], StorageLevel(disk, 
memory, deserialized, 1 replicas)
      :           +- *(1) FileScan orc default.table1[a#37,b#38,c#39,d#40] 
Batched: true, DataFilters: [], Format: ORC, Location: 
InMemoryFileIndex[file:/Users/maropu/Repositories/spark/spark-master/spark-warehouse/table1],
 PartitionFilters: [], PushedFilters: [], ReadSchema: 
struct<a:int,b:int,c:int,d:int>
      +- Project [a#37 AS a#73]
         +- Filter isnotnull(a#37)
            +- InMemoryRelation [a#37, b#38, c#39, d#40], StorageLevel(disk, 
memory, deserialized, 1 replicas)
                  +- *(1) FileScan orc default.table1[a#37,b#38,c#39,d#40] 
Batched: true, DataFilters: [], Format: ORC, Location: 
InMemoryFileIndex[file:/Users/maropu/Repositories/spark/spark-master/spark-warehouse/table1],
 PartitionFilters: [], PushedFilters: [], ReadSchema: 
struct<a:int,b:int,c:int,d:int>
   ```
