### Is your feature request related to a problem or challenge? @Veeupup implemented the great `parquet_metadata` feature in https://github.com/apache/arrow-datafusion/pull/8413 ❤️ While playing around with it however, I noticed that the formatting of string statistics was not super easy to interpret as it is formatted something like `[72, 101, 108, 108, 111] ` For example: ```shell andrewlamb@Andrews-MBP:~/Software/arrow-datafusion$ datafusion-cli -c "select * from parquet_metadata('parquet-testing/data/data_index_bloom_encoding_stats.parquet')"; DataFusion CLI v33.0.0 +--------------------------------------------------------------+--------------+--------------------+-----------------------+-----------------+-----------+-------------+------------+----------------+------------+--------------------------+--------------------------+------------------+----------------------+--------------------------+--------------------------+--------------------+--------------------------+-------------------+------------------------+------------------+-----------------------+-------------------------+ | filename | row_group_id | row_group_num_rows | row_group_num_columns | row_group_bytes | column_id | file_offset | num_values | path_in_schema | type | stats_min | stats_max | stats_null_count | stats_distinct_count | stats_min_value | stats_max_value | compression | encodings | index_page_offset | dictionary_page_offset | data_page_offset | total_compressed_size | total_uncompressed_size | +--------------------------------------------------------------+--------------+--------------------+-----------------------+-----------------+-----------+-------------+------------+----------------+------------+--------------------------+--------------------------+------------------+----------------------+--------------------------+--------------------------+--------------------+--------------------------+-------------------+------------------------+------------------+-----------------------+-------------------------+ | parquet-testing/data/data_index_bloom_encoding_stats.parquet | 0 | 14 | 1 | 163 | 0 | 4 | 14 | "String" | BYTE_ARRAY | [72, 101, 108, 108, 111] | [116, 111, 100, 97, 121] | 0 | | [72, 101, 108, 108, 111] | [116, 111, 100, 97, 121] | GZIP(GzipLevel(6)) | [BIT_PACKED, RLE, PLAIN] | | | 4 | 152 | 163 | +--------------------------------------------------------------+--------------+--------------------+-----------------------+-----------------+-----------+-------------+------------+----------------+------------+--------------------------+--------------------------+------------------+----------------------+--------------------------+--------------------------+--------------------+--------------------------+-------------------+------------------------+------------------+-----------------------+-------------------------+ 1 row in set.

For example as duckdb does (showing that `[72, 101, 108, 108, 111] ` as `Hello` ```shell andrewlamb@Andrews-MBP:~/Software/arrow-datafusion$ duckdb -c "select * from parquet_metadata('parquet-testing/data/data_index_bloom_encoding_stats.parquet')"; ┌──────────────────────┬──────────────┬────────────────────┬──────────────────────┬─────────────────┬───────────┬─────────────┬────────────┬────────────────┬───┬─────────────────┬─────────────────┬─────────────┬──────────────────────┬───────────────────┬──────────────────────┬──────────────────┬──────────────────────┬────────────� �─────────┐ │ file_name │ row_group_id │ row_group_num_rows │ row_group_num_colu… │ row_group_bytes │ column_id │ file_offset │ num_values │ path_in_schema │ … │ stats_min_value │ stats_max_value │ compression │ encodings │ index_page_offset │ dictionary_page_of… │ data_page_offset │ total_compressed_s… │ total_uncompressed… │ │ varchar │ int64 │ int64 │ int64 │ int64 │ int64 │ int64 │ int64 │ varchar │ │ varchar │ varchar │ varchar │ varchar │ int64 │ int64 │ int64 │ int64 │ int64 │ ├──────────────────────┼──────────────┼────────────────────┼──────────────────────┼─────────────────┼───────────┼─────────────┼────────────┼────────────────┼───┼─────────────────┼─────────────────┼─────────────┼──────────────────────┼───────────────────┼──────────────────────┼──────────────────┼──────────────────────┼────────────� �─────────┤ │ parquet-testing/da… │ 0 │ 14 │ 1 │ 163 │ 0 │ 4 │ 14 │ String │ … │ Hello │ today │ GZIP │ BIT_PACKED, RLE, P… │ │ │ 4 │ 152 │ 163 │ ├──────────────────────┴──────────────┴────────────────────┴──────────────────────┴─────────────────┴───────────┴─────────────┴────────────┴────────────────┴───┴─────────────────┴─────────────────┴─────────────┴──────────────────────┴───────────────────┴──────────────────────┴──────────────────┴──────────────────────┴────────────� �─────────┤ │ 1 rows 23 columns (18 shown) │ └──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────� �─────────┘ andrewlamb@Andrews-MBP:~/Software/arrow-datafusion$ ``` ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
