  • Archiving accelerator-only database tables
    Patent number: 11500833
    Abstract: A DBMS manages a high-performance accelerated database that is synchronized with a conventional client database. The accelerated database contains both “regular” accelerated tables, which each duplicate a table of the client database, and accelerator-only tables (AOTs) that are unique to the accelerated database and that may be used for analytical purposes. AOT rows are archived by moving the rows to a dedicated accelerator-only archive stored in the accelerated database. When a user query attempts to access accelerator-only data, the DBMS rewrites the query to adapt the requested operations to the accelerated database's partitioned archive/non-archive structure. The rewritten query specifies steps for accessing archived and non-archived accelerator-only data without forcing the DBMS front-end to generate a merged view of archived and non-archived accelerator-only data.
