This disk arrangement favors sequential reads 这种磁盘方案有助于连续的读取。
During heavy sequential reads from one tablespace , i o activity on other tablespaces is very light , or even nonexistent 当从一个表空间连续读取的任务比较重时,其他表空间的i / o操作却极其稀少,甚至是没有。
This arrangement is made with the following concern : in the tpc - h workload , a significant amount of i o operations are sequential reads 这种方案是出于以下考虑而布置的:在tpc - h工作负载中,相当大一部分i / o操作都是连续的读取操作。
