Accelerating database queries containing bitmap-based conditions

摘要: Systems, methods and articles of manufacture for accelerating database queries containing bitmap-based conditions are described herein. An embodiment includes determining a bitmap, where the bitmap represents set rows that have satisfied one or more conjunctive which preceded conjunct is disjunction in query expression restricting evaluation disjunct within to represented by bitmap. Another satisfaction result preceding disjuncts scope not determined In this way, embodiments present invention enable acceleration disjunctions on table, as well reduce temporary resources consumed such queries.
