I’ve some doubts too. I try to write a parquet file locally. What I learned is to use `SerializedFileWriter` and manually call `next_row_group` to append data chunks. But by setting `WriterProperties::data_pagesize_limit` and `WriterProperties::max_row_group_size`, shouldn’t a writer automatically divided data into appropriate row groups? I could assume by calling `write_batch` repeatedly and the writer would take care of the details to keep it stick to the threshold values. A few more examples on read / write parquet file would be really great. Thanks! 😊 -- This is an automated message from the Apache Git Service.
