Use All Space
Go Up to Restoring a database using IBConsole
Option values are True and False.
To restore a database with 100% fill ratio on every data page, set the Use All Space option to True. By default, space is reserved for each row on a data page to accommodate a back version of an UPDATE or DELETE. Depending on the size of the compressed rows, that could translate to any percentage.
This function corresponds to the -use_all_space option of gbak.
