摘要
阐述了制约海量数据装入速度的5个主要因素,提出了减少磁盘I/O冲突、DBMS装入功能的选用、分解数据、预先排序、消除并发处理等5种主要的提高装入速度的办法,综合应用这些方法可以较好地解决海量数据装入速度慢的缺点.
The five factors restricting the velocity of mass of data encasement are elaborated in this article. The corresponding methods such as reducing the collision of disk I/O, choosing the function of DBMS encasement, decomposing of data, ordering in advance and avoiding intercurrently deal are presented to accelerate the encasement. The disadvantage of mass of data encasement could be overcome by integrating those methods.
