Because new rows are inserted in the part of the table that contains rows with similar values, data remains clustered without the need to run the REORG utility.
由于新行是插在表中具有近似值的行附近的位置,因此数据仍然是聚合的,而不需要运行REORG实用程序。
But, row level sampling may produce more accurate statistics if relational data values are highly clustered.
但是,如果关系数据值是高度聚集的,那么行级抽样可以产生更精确的统计信息。

This works fine on a single computer, but when you move to a clustered model, it's important that cached data remain consistent across all nodes.
在单一计算机上,这种方式工作得很好,但是在进入集群模型时,重要的是缓存的数据要在所有节点间保持一致。
Additional solutions, depending on the errors, may be to manually rebuild non-clustered indexes, manually drop and reload a table if the data is static, and so on.
另外的解决方案,取决于具体的错误,可能是手工重建非聚簇索引,如果数据是静态的手工扔掉和重新载入表,诸如此类。
You create the data source in a clustered environment in the same manner as you do in a single-server environment, except that you define the scope for the data source as cluster.
除非将数据源的作用域定义为集群,否则您可利用在单服务器环境中的相同方法,在集群环境中创建数据源。
Finally, the clustering of the data is guaranteed and cannot become un-clustered, as is normally the case in OLTP systems.
最后,数据的集群受到保障,数据不会又变成非集群状态,在OLTP系统中就常常会出现这种情况。
Your clustered index is the order the data is stored in the table, so you can only have one clustered index per table.
你的聚集索引顺序表中的数据存储,所以你每个表只能有一个聚集索引。
The Heat Map displays values on either a clustered, linear or logarithmic scale, to help spot uneven distribution of data across threads.
“HeatMap”中能够以集群(clustered)、线性(linear)或者对数(logarithmic)的方式显示值,以帮助我们跨线程识别出对数据的不平均分布。
Besides reorganizing one or more indexes, large object data types (LOBs) that are contained in the clustered index or underlying table are compacted by default when an index is reorganized.
重新组织索引时,除了重新组织一个或多个索引外,默认情况下还将压缩聚集索引或基础表中包含的大型对象数据类型(lob)。
He also said that in testing with the Spring Pet Clinic reference application, clustered Ehcache yielded higher throughput and lower latency than a database for read-only and read-mostly data access.
Ari还说到,在测试SpringPetClinic参考应用时发现集群的Ehcache要比数据库(基本上都是只读访问)拥有更高的吞吐量和更低的延时。
WebSphere provides real-time fully coherent data sharing for clustered applications.
WebSphere为集群方式的应用程序提供了实时的、完全一致的数据共享。
It may also provide more accurate statistics if the data is clustered (obtains a sample that better represents overall table data).
如果数据是群集的,它还可以提供更准确的统计信息(所获得的样本更好地代表了整个表数据)。
The structure of the row locator depends on whether the data pages are stored in a heap or a clustered table.
行定位器的结构取决于数据页是存储在堆中还是聚集表中。
The second, clustered the data, and then discovered frequent items sets in the result of clustering.

DATA already sorted creates the clustered index with the SORTED_DATA option.
“数据已经排序”用SORTED _ DATA选项来创建聚集索引。
To improve XML data query, all nodes are clustered based their labels, and path information of each node is kept in bit vectors.
为了提高XML数据查询处理效率,提出对XML数据结点采用标签聚类存储,同时结点路径信息存储在位向量中。
UPDATE and DELETE operations are often accelerated by clustered indexes because these operations require large amounts of data to be read.
聚集索引通常可加快UPDATE和DELETE操作的速度,因为这些操作需要读取大量的数据。
