  • Increase memory scalability using table-specific memory cleanup
    Patent number: 9619153
    Abstract: A method to increase memory scalability using a table-specific memory cleanup is provided. The method may include determining whether a specific table within a set of tables is a candidate for elimination. The method may also include unloading a plurality of respective metadata associated with the specific table in response to the determination that the specific table is a candidate for elimination, whereby unloading the plurality of respective metadata includes temporarily deactivating the table. The method may further include creating a point-in-time snapshot copy of the respective metadata associated with the specific table. The method may also include saving the created point-in-time snapshot on a disk. The method may include detecting an access of the specific table. The method may also include constructing a plurality of respective table metadata structures using the saved created point-in-time snapshot, whereby the constructing is in response to detecting the access of the specific table.
