pub fn write_parquet(list: &[Data]) -> Result<Vec<u8>>Expand description
Write a list of commonmeta records as a single Parquet file. Alongside a
flattened tabular projection of each record’s fields (for filtering in
tools like DuckDB without parsing JSON), every row also carries a json
column with the record’s complete serialization, so read_parquet
round-trips losslessly.
