Hi everyone,
reading the descriptions here <https://parquet.apache.org/documentation/latest/#metadata> https://parquet.apache.org/documentation/latest/#metadata, I think it should be possible in general to add arbitrary key-value metadata to any parquet column. Is that correct? If yes, in the https://github.com/apache/arrow repository, I do not really find that functionality in the API (no such thing as KeyValueMetaData or similar in ColumnChunkMetaData::ColumnChunkMetaDataImpl), so I guess that it's either not yet implemented or I just don't see it. If it's not implemented yet, is that something someone not very familiar with the code-base like me could implement or does that require a little more insight and experience? Regards, Roman
