摘要
Growth of databases in read-repeatable environments is controlled by an erase list maintained for each generation of the database. The erase list identifies pages which are retained in the database to facilitate read repeatability. The system uses the erase list to identify obsolete pages which can be removed from the database. The removed pages can then be reclaimed for re-use by a subsequent generation.
