该代数由基于成本的优化器使用,该优化器能够自由混合使用常规运算符以及与压缩有关的运算符。
This algebra is exploited by a cost-based optimizer that can freely mix regular and compression-aware operators.
按位运算符会对两个自变量中对应的位执行布尔代数,并最终生成一个结果。
Bitwise operators perform Boolean algebra on the corresponding bits in the two arguments to produce the result.
