> But GetColumnDataDecryptor will happily reuse the footer_data_decryptor_ for all columns that use footer key encryption... Hmm yeah that could be a problem. > And besides, even if we were creating a distinct decryptor per column chunk, the caller may still want to parallelize reading at the page level. It looks like the `PageReader` API doesn't provide a way to parallelise reading though, you can only iterate over data pages sequentially, so I don't think this is a concern: https://github.com/apache/arrow/blob/990cdf7dca8ba74d1c3b9a7b14898011a1142356/cpp/src/parquet/column_reader.h#L156-L158 -- This is an automated message from the Apache Git Service.
