For example, a compiler may choose to optimize a loop index variable by storing it in a register, or the cache may delay flushing a new value of a variable to main memory until a more opportune time.
例如，编译器为了优化一个循环索引变量，可能会选择把它存储到一个寄存器中，或者缓存会延迟到一个更适合的时间，才把一个新的变量值存入主存。

In general, a nested loop join with sort composite is favored by the optimizer if the inner index is well-clustered and the inner table is expected to be probed many times.
一般来说，如果内部索引是良好的集群且预测内部表被多次探测，则使用复合排序的嵌套循环联将受到优化器的青睐。
To refresh your memory, Listing 20 shows how a typical for loop might be used — note the usage of an index variable to not only move through the list, but also to indicate position.
