HYBRID DATA STORAGE AND LOAD SYSTEM WITH POSITION LOOKUP

Abstract:

System, method, and various embodiments for providing a hybrid data storage and load system are described herein. An embodiment operates by receiving a lookup request for a row identifier (ROWID) of a row of a table of a database, wherein the lookup request identifies a row position of the ROWID. A page corresponding to the row position is identified from an address vector stored in memory storage. The identified page is loaded from the disk storage to the memory storage. The row position is identified within the page from the memory storage. The ROWID stored in the row position is identified within the page. The ROWID is returned responsive to the lookup request.
