METHOD AND SYSTEM FOR MEMORY EFFICIENT, UPDATE OPTIMIZED, TRANSACTIONAL FULL-TEXT INDEX VIEW MAINTENANCE |
摘要 |
Methods and systems are directed to an update-optimized and memory-efficient method for transactional full-text index view maintenance. Embodiments include a method and system of reducing the overhead requirements of maintaining a transactional index view in the case of a large number of updates at any particular time. The method involves maintaining a single blacklist bitmap across updated transactional query views, applying the latest set of updates to the bitmap when a new view is required, and post-adjusting the bitmap when the transactional view is created to ensure that entries that should be visible have not been removed. |
