wgtmac opened a new issue, #34888:
URL: https://github.com/apache/arrow/issues/34888

   ### Describe the enhancement requested
   
   Parquet specs support storing key-value metadata provided by the user. However, the parquet-cpp writer can only set it via `ParquetFileWriter::Open()`. Sometimes user may want to add extra information to it while writing. So it is good to support adding extra key-value metadata any time before closing the file writer.
   
   ### Component(s)
   
   C++, Parquet
