Allowing too much free space, however, could cause extra pages to be read for queries and largely defeat the purpose of using a clustering index.───不過,如果允許太多自由空間的存在,則可能導致查詢時需要讀取額外的頁,這反而大大違反了使用群集索引的本意。
Common alternatives include clustering index columns or other unique key columns.───常見的替代項包括索引列或其他唯一鍵列的群集。
Avoid having any indexes on the table, if possible, but particularly not a clustering index.───盡可能避免表上有任何索引,尤其是不要有群集索引。
Optimization Method of Clustering Index in Data Warehouse───數據倉庫中聚簇索引的優化方法
Approximate k-NN Search in High-Dimensional Spaces Based on the Clustering Index Tree───基于聚類索引樹的高維近似檢索算法
According to different influence of evident degree of clustering index to power load, the weighted demarcating method is inducted.
Common alternatives include clustering index columns or other unique key columns.
Allowing too much free space, however, could cause extra pages to be read for queries and largely defeat the purpose of using a clustering index.
Avoid having any indexes on the table, if possible, but particularly not a clustering index.
According to the experience from engineering practices and reliability theory of building structures, clustering index, quantified criterion and clustering classes are confirmed.
This paper introduces a newly generalized and dynamic structure for the similarity retrieval of high dimensional feature vectors called the recursive clustering index tree.
With the algorithms of video feature extraction, similarity measure and fast search based on clustering index table, a video similarity search system was implemented.
A successful clustering strategy can reduce the number of DB2 GETPAGEs (and also I/Os), especially if many sequential scans use the clustering index.
The final algorithm is used when the table has a clustering index; in which case DB2 tries to insert each row on a page with similar key values (according to the clustering index).
