  • Index entry eviction
    Patent number: 8397028
    Abstract: Systems, methods embodied on computer-readable media, and other embodiments associated with index entry eviction are described. One example method includes selecting an index entry for eviction from a bucket of index entries based on a time value, a utility value, and a precedence value. A precedence value may be a value associated with an index entry that is static over time. Additionally, results of a function that compares two precedence values may be static over time. The example method may also include providing an index entry identifier that identifies the index entry.
