### Is your feature request related to a problem or challenge? From `ParquetExec` metrics, with predicate pushdown enabled: > metrics=[output_rows=0, elapsed_compute=96ns, row_groups_matched_bloom_filter=0, row_groups_matched_statistics=21050, file_scan_errors=0, pushdown_rows_matched=0, row_groups_pruned_statistics=173576, row_groups_pruned_bloom_filter=21050, file_open_errors=0, num_predicate_creation_errors=0, bytes_scanned=25023432248, pushdown_rows_pruned=0, page_index_rows_pruned=0, predicate_evaluation_errors=0, page_index_rows_matched=0, time_elapsed_scanning_until_data=16.622753ms, time_elapsed_processing=72.280463608s, pushdown_eval_time=382ns, page_index_eval_time=3.177676ms, time_elapsed_scanning_total=16.661811ms, time_elapsed_opening=102.989073638s] For example, `pushdown_rows_matched` and `pushdown_rows_pruned` are far away from each other, even though they refer to roughly the same thing. The unstable sort also makes it hard to compare multiple `EXPLAIN ANALYZE` results. ### Describe the solution you'd like Sort them alphabetically, to break ties in the (very) partial order induced by `MetricValue::display_sort_key` ### Describe alternatives you've considered Split `Metrics` by categories and display each on a line; or split `ParquetExec` into "virtual" execution plans to reflect the successive opening and filtering steps done in `ParquetOpener`. That is more work, though. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
