一种自适应内存排序能够在排序过程中动态改变所使用的内存量。本文所描述的方法根据输入大小以及数据库系统中运行的其他排序的内存需求来调整内存使用情况。它为小规模排序节省内存空间,为大规模排序减少排序时间,并在并发排序之间平衡内存使用。当多个排序并发运行时,整体系统性能得以提高。
A memory-adaptive sort is able to dynamically change the amount of memory used during sorting. The method described in this paper adjusts memory usage according to input size and memory requirements of other sorts running in a database system. It saves memory space for small sorts, reduces sort time for large sorts, and balances memory usage among concurrent sorts. Overall system performance is improved when several sorts are running concurrently.
