-------------------------------------
Hi [~younggyuchun],
I'd take a look at how SHOW PARTITIONS works today:
-
[https://github.com/apache/spark/blob/36803031e850b08d689df90d15c75e1a1eeb28a8/sql/core/src/main/scala/org/apache/spark/sql/execution/command/tables.scala#L1023]
which returns a list of string paths.
It would be great that with [DataSourceV2
tables|[https://github.com/apache/spark/blob/36803031e850b08d689df90d15c75e1a1eeb28a8/sql/catalyst/src/main/java/org/apache/spark/sql/connector/catalog/Table.java#L43]],
we can return the list of partitions
([https://github.com/apache/spark/blob/36803031e850b08d689df90d15c75e1a1eeb28a8/sql/catalyst/src/main/java/org/apache/spark/sql/connector/catalog/Table.java#L60])
where each Transform is a separate column.
