When predicate pushdown is enabled, `DataSourceExec` with `ParquetSource`
gains the following metrics:
+- `output_rows_skew`: output skew score derived from per-partition
`output_rows`. `0%` is perfectly balanced, `100%` is maximally skewed, and
`N/A` means no output rows were produced.
- `page_index_rows_pruned`: number of rows evaluated by page index filters.
The metric reports both how many rows were considered in total and how many
matched (were not pruned).
- `page_index_pages_pruned`: number of pages evaluated by page index filters.
The metric reports both how many pages were considered in total and how many
matched (were not pruned).
- `row_groups_pruned_bloom_filter`: number of row groups evaluated by Bloom
Filters, reporting both total checked groups and groups that matched.
