@joeyac Sorry to bring it up again... but I am deeply confused about this line of code: `auto column_struct = std::static_pointer_cast<arrow::StructArray>(table->GetColumnByName("column")->chunk(0)); ` since GetColumnByName returns a shared_ptr to ChunkedArray, would accessing only the chunk(0) returns incomplete data? like if the data file is huge and truncated (from the document I couldn't really get the idea). Could you say a bit more about this? Thanks a lot! ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
