ABSTRACT:
A database management system is described. The system includes a computer storage medium having a primary storage medium and an overflow storage medium. The system also includes a manager for managing a plurality of data structures (queues) stored in the computer storage medium. The manager receives a request to store a data object in a target data structure. The manager determines whether an overflow mode condition currently exists. If an overflow mode condition does not currently exist, then the manager determines whether a combined size of all data structures stored in the primary storage medium plus a size of the data object is greater than a predetermined threshold. If a combined size of all data structures stored in the primary storage medium plus a size of the data object is greater than a predetermined threshold, then the manager enters an overflow mode. Also, the manager selects one or more data structures currently stored in the primary storage medium, and moves the selected data structures from the primary storage medium to the overflow storage medium. The overflow storage medium is then directly accessed to process any subsequent actions involving these data structures.
