  • Hybrid table implementation by using buffer pool as permanent in-memory storage for memory-resident data
    Patent number: 10114908
    Abstract: Embodiments relate to a method, system, and computer program product for data management. An aspect includes a search index that is created for a database. The search index has a reference value of a first or a second type associating data to a storage location in a first memory or a second memory respectively. Responsive to a data retrieval request, data is accessed using the reference value from the first or the second memory. If there is a data migration between the first and second memory storage, the reference values are then recalculated and altered in the search index accordingly.

  • Index for hybrid database
    Patent number: 9495398
    Abstract: Providing an index for a database table that includes a first portion of rows stored in a memory device and a second portion of rows stored in a disk device. A request is received relating to a specific row of the database table. An index that includes entries for each row of the database table stored in the memory device and entries for a subset of the rows of the database table stored in the disk device is accessed. A connection is made to the memory device if the specific row is stored in the memory device, and a connection is made to the disk device if the specific row is stored in the disk device. An action related to the specific row is performed based on the received request.
