information would be lost, as multiplication by 2 is equivalent to shifting. The advantage of using a prime is less clear, but it is traditional. A nice property of 31 is that the multiplication can be replaced by a shift and a subtraction for better performance:31 * ...

字符串是 Redis 最基本的数据结构 ,它将以一个键和一个值存储于 Redis 内部,很像Java的 Map 结构 ,让 Redis 通过键去找到值。 Redis 会通过 key 去找到对应的字符串 ,比如通过 keyl 找到 valuel。假设产品的编号为 0001 , 只要设置 key 为 product_0001 , 就可以通过 product_0001去保存该产品到 Redis...
