### Query engine
spark
### Question
I was using Iceberg with PySpark, and using JDBC catalog, and set warehouse
to GCS
I creata a table using `date` as partition key.
I write some data into table, and decide to delete date=20240220, so I
```
spark.sql(f"DELETE FROM {iceberg_table} WHERE date = '20241220'")
spark.sql(f"CALL {catalog_name}.system.expire_snapshots('{iceberg_table}')")
```
I find that the parquet file under `date=20240220` is deleted, but the
folder `date=20240220` still remain
Also the same, when I drop the table using
```
spark.sql(f"DROP TABLE {iceberg_table} PURGE")
```
the data will be deleted, but all the partition folders will still remain
These behavior cause many empty folders in my gcs, I wonder if there is any
way I can do in iceberg to prevent this from happening?
