incremental index

基本解釋

An incremental update of the index will take less time and resources than the creation of the initial index.
索引的增量更新將比初始索引創(chuàng)建需要的時(shí)間和資源更少。
Incremental backup allows you to back up only index and data pages that have changed since a previous backup.
增量備份允許衹備份自上一次備份以來(lái)發(fā)生變化的索引和數(shù)據(jù)頁(yè)。
This means that DB2 chooses either the rebuild or incremental index maintain approach, whichever is the best fit.
這意味著，DB2 從重新?lián)k建和增量索引維護(hù)兩種方法中選擇最郃適的方法。
