wgtmac opened a new pull request, #34889: URL: https://github.com/apache/arrow/pull/34889
### Rationale for this change 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. ### What changes are included in this PR? Add a new interface `void AddKeyValueMetadata(std::shared_ptr<const KeyValueMetadata> key_value_metadata)` to the `ParquetFileWriter` class. User can now add more key-value metadata to the file if not closed. ### Are these changes tested? Added a new `Metadata.TestAddKeyValueMetadata` test to verify key-value metadata added before closing the writer are well preserved. ### Are there any user-facing changes? Yes, user can add custom key-value metadata whenever writer is not closed. -- This is an automated message from the Apache Git Service.
