Is your feature request related to a problem or challenge? Please describe what you are trying to do.

I have been using EXPLIN ANALYZE to do some adhoc analysis on our query output

At the moment, explain analyze shows all statistics for all parquet files scanned -- this is often overwhelming for manual analysis

Describe the solution you'd like
What I would like is a summarized version of all the statistics (like we do for partitions) for all the parquet files. I would like per-file breakdowns only reported with EXPLAIN ANALYZE VERBOSE so I can understand at a high level what happened

Something like:

|                   |             ParquetExec: limit=None, metrics=[output_rows=47870000, elapsed_compute=4ns, spill_count=0, spilled_bytes=0, mem_used=0, bytes_scanned=35328432, row_groups_pruned=0, predicate_evaluation_errors=0, pushdown_rows_filtered=4, num_predicate_creation_errors=0, pushdown_eval_time=1.23756ms, time_elapsed_opening=27.569443574s, time_elapsed_processing=2.772865879s, time_elapsed_scanning=646.659086ms,

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context

For example

Here is an example output:
