METADATA TABLE MANAGEMENT SCHEME FOR DATABASE CONSISTENCY

摘要

A database management method according to an embodiment of the present invention is provided. The method includes, with recovery logic, finding a first metadata table using a starting metadata table key, reading a first metadata table, by recovery logic, a first metadata table of the first metadata table. Retrieving a subsequent metadata table key, finding a second metadata table based on the first subsequent metadata table key or a third subsequent metadata table key of the third metadata table, by the recovery logic, a third The subsequent metadata table has a third metadata table range between the first metadata table range of the first metadata table and the second metadata table range of the second metadata table, and by the recovery logic, the second metadata Reading the data table, determining whether the second metadata table does not have valid keys in the range of the second metadata table by the recovery logic, and using the memory space associated with the second metadata table by the recovery logic It may include the step of enabling.
