Description

The current API allows writing RowGroups with specified numbers of rows, however does not allow writing RowGroups with specified size. In order to write RowGroups of specified size we need to write rows in chunks while checking the total_bytes_written after each chunk is written. This is currently impossible because the call to NextColumn() closes the current column writer.
