peter-toth commented on issue #23802: [SPARK-26893][SQL] Allow partition 
pruning with subquery filters on file source
URL: https://github.com/apache/spark/pull/23802#issuecomment-465571583
 
 
   > @peter-toth I think what @cloud-fan is suggesting is to replace the 
subquery with its literal value before listing the partitions from the Hive 
metastore (please see `HiveShim.listPartitionsByFilter`). But IIUC, this should 
be done in `HiveStrategies` and I'd propose to do this in another PR since I 
consider it a different/indipendent change from this one. What do you think 
guys?
   
   @mgaido91 thanks, I get it now and agree about independent change.
