Abstract: Provided is a method of database management including locating, with a recovery logic, a first metadata table using a beginning metadata table key, reading, by the recovery logic, the first metadata table, retrieving, with the recovery logic, a first next metadata table key of the first metadata table, locating, by the recovery logic, a second metadata table based on the first next metadata table key or based on a third next metadata table key of a third metadata table having a third metadata table range between a first metadata table range of the first metadata table and a second metadata table range of the second metadata table, reading, by the recovery logic, the second metadata table, determining, by the recovery logic, the second metadata table lacks valid keys in the second metadata table range, and making available, by the recovery logic, memory space associated with the second metadata table.
