Have you looked at the output of `EXPLAIN ANALYZE` for your query? That will
show you what metrics are available
I don't think we have upload/download bytes but I do think there are a bunch
of parquet level metrics like
```sql
| | ParquetExec: file_groups={1 group:
[[data.parquet]]}, projection=[<cols>], limit=1, metrics=[output_rows=1,
elapsed_compute=1ns, bytes_scanned=4763, predicate_evaluation_errors=0,
page_index_rows_filtered=0, pushdown_rows_filtered=0, file_open_errors=0,
row_groups_pruned=0, file_scan_errors=0, num_predicate_creation_errors=0,
time_elapsed_processing=7.350966ms, time_elapsed_opening=1.363919ms,
pushdown_eval_time=2ns, time_elapsed_scanning_until_data=6.981077ms,
page_index_eval_time=2ns, time_elapsed_scanning_total=6.981147ms] |
```
We can probably add more
