Hello, Using the arrow cpp api I am creating a MemoryMappedFile with excess space and am writing to it using a RecordBatchWriter. When closing the RecordBatchWriter I am finding that I don't have the exact size of what has been written to the MemoryMappedFile and can't truncate/resize the file. Is there a way for me to get the total number of bytes that have been written to the MemoryMappedFile? I found that RecordBatchWriter::stats() does not include of the number of bytes written when RecordBatchWriter::Close() is called. -- This is an automated message from the Apache Git Service.
