### Is your feature request related to a problem or challenge? In https://github.com/apache/arrow-datafusion/pull/7562 @devinjdangelo added the (really neat) feature to write a single parquet file in parallel. This feature is enabled by a feature flag (`allow_single_file_parallelism), that defaults to off. We haven't turned it on by default yet because the resulting parquet files don't have the necessary index structures (bloom filter, column_index, and offset_index) needed for high performance (see details in this conversation https://github.com/apache/arrow-datafusion/pull/7562/files#r1327037733) ### Describe the solution you'd like I would like the created parquet files to have the necessary index structures -- https://github.com/apache/arrow-rs/issues/4823 tracks adding such an API upstream in arrow-rs. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
