Major Description
V2 file scans have duplication in the description. This is because FileScan uses the metadata to create the description, but each file type overrides metadata and the description adding the same metadata.
Example from a parquet agg pushdown explain:
+- BatchScan parquet file:/...[min(_3)#814, max(_3)#815, min(_1)#816, max(_1)#817, count
#818L, count(_1)#819L, count(_2)#820L, count(_3)#821L] ParquetScan DataFilters: [], Format: parquet, Location: InMemoryFileIndex(1 paths)[file:/..., PartitionFilters: [], PushedAggregation: [MIN(_3), MAX(_3), MIN(_1), MAX(_1), COUNT(*), COUNT(_1), COUNT(_2), COUNT(_3)], PushedFilters: [], PushedGroupBy: [], ReadSchema: struct<min(_3):int,max(_3):int,min(_1):int,max(_1):int,count:bigint,count(_1):bigint,count(_2)..., PushedFilters: [], PushedAggregation: [MIN(_3), MAX(_3), MIN(_1), MAX(_1), COUNT(*), COUNT(_1), COUNT(_2), COUNT(_3)], PushedGroupBy: [] RuntimeFilters: []
