Team, I am looking for ways to store more metadata (key-value style) at the row group level using the parquet-cpp library. However the RowGroupMetaData class defined in [1] doesn't provide anything relevant for what I am looking. Does the existing library support something like this?
Also I observed that the below code returns file level KeyValueMetadata while I was expecting KeyValueMetadata at the row-group level. Kindly correct me if I am doing something wrong. arrow::FileReader->ReadRowGroup(index, rg); (*rg)->schema()->metadata() [1] https://github.com/apache/parquet-cpp/blob/master/src/parquet/file/metadata.h - Rahul
