This disk arrangement favors sequential reads 這種磁盤方案有助于連續的讀取。
During heavy sequential reads from one tablespace , i o activity on other tablespaces is very light , or even nonexistent 當從一個表空間連續讀取的任務比較重時,其他表空間的i / o操作卻極其稀少,甚至是沒有。
This arrangement is made with the following concern : in the tpc - h workload , a significant amount of i o operations are sequential reads 這種方案是出于以下考慮而布置的:在tpc - h工作負載中,相當大一部分i / o操作都是連續的讀取操作。
