A second significant performance advantage is that the initial join performed by WebSphere Federation Server is "reducing"; that is, it outputs far less data than it reads in from the sources.
第二个显著的性能优点是,WebSphereFederationServer执行的初始连接“减少”了;也就是说,它输出的数据远远少于从源数据读取的数据。
You can add a call in YY_INPUT to the function GetNextChar , which reads the data from a file and keeps information about the position of the next character to read.

DB2 has a very efficient and optimized backup utility that multiplexes the data pages it reads from the database and writes them to the target device in a randomized order.
DB2有一个非常高效的备份实用程序,它可以将从数据库读出的数据页分成多个部分,并以随机的顺序将它们写到目标设备。
Because the DB2 subsystem reads data in the order in which it needs to process it, clustering helps reduce expensive SORTs.
由于db2子系统会按照处理的顺序来读取数据,因此集群能帮助降低昂贵的sort操作数。

At startup, the on demand configuration code inside the secure proxy reads the static route file and builds the in-memory routing data.
在启动后,安全代理内部的随需应变配置代码将读取静态路由文件并构建内存路由数据。
The benefit of sharding (like partitioning) is that it compacts big data: individual tables are smaller in each shard, which allows for faster reads and writes, which increases performance.
切分的好处(如分区一样)在于它可以压缩大型数据:单独的数据表在每个切分中相对较小,这样就可以支持更快速的读写速度,从而提高性能。
As a program does reads and writes to the file, the AIX kernel caches the file's data in memory as non-computational permanent storage pages.
随着程序对该文件进行读写操作,AIX内核将该文件的数据作为非计算性的永久存储分页在内存中进行缓存。
In this pattern, the client always reads and writes against a server-side data store.
在该模式下,客户机始终读写服务器端数据存储。
This happens when a transaction reads the same data twice, while another transaction modifies the data between the two reads, resulting in in a different result for each read.
这个隔离级只有当一个事务对同样的数据进行两次读操作而其他事务修改了两次读操作之间的数据,从而导致了每个读操作的结果不同时才会发生。
For data-oriented XML documents, the target is usually the data format of a DBMS or an in-memory representation by an application that reads XML files.
