而在使用相同方法的其他算法中，采用有效的棋盘表现方法是一个介于复杂性，速度和空间需求之间的权衡。

In the same way as other algorithms, the use of efficient board representations is a tradeoff between complexity, speed, and space requirements.

这个特性是以表空间为单位启用或禁用的，从而可以有效地使 DB2 中的某些数据使用文件缓存，而另一些数据则绕过文件缓存。

This feature is available on a tablespace-by-tablespace basis, effectively allowing some data in DB2 to use file caching and other data to bypass it.

要进行有效的日志记录，需要使用大量的磁盘空间，并且在多线程环境中，所需的磁盘空间会成倍地增加，因为大量的线程都在记录它们的跟踪信息。

A significant amount of disk space is required for effective logging, and it increases many fold in a multi-threaded environment where numerous threads write their trace.
