a) The sizes of these files (corresponding to the tables) could be different and then one large file would limit the level of parallelism since it would be processed by a single thread.
b) If you have to stream the backup how do you reconcile these

MEB now supports innodb_undo_directory[logs][tablespace] option variables. When backup is executed, undo datafiles (up to number
