[jira] [Created] (ARROW-8150) [Rust] Allow writing custom FileMetaData k/v pairs

David Kegley created ARROW-8150:
-----------------------------------

             Summary: [Rust] Allow writing custom FileMetaData k/v pairs
                 Key: ARROW-8150
                 URL: https://issues.apache.org/jira/browse/ARROW-8150
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: David Kegley


It would be nice to be able to write custom k/v metadata in the rust implementation of parquet. It looks like there was a plan for this previously but it has not been implemented yet.

[https://github.com/apache/arrow/blob/a1eb440c92ae1c8edc93bc9ae646a8e371d756c6/rust/parquet/src/file/writer.rs#L182]

I have a working implementation that adds a `key_value_metadata` field to the `WriterProperties` struct
