LINSERT key BEFORE|AFTER pivot value

自2.2.0起可用。

时间复杂度: O(N)其中N是在查看数据透视之前要遍历的元素的数量。这意味着插入列表(头部)左端的某处可以被认为是O(1),并且在右端(尾部)的某处插入的是O(N)。

插入value存储在key参考值之前或之后的列表中pivot

key不存在时,它被视为空列表,不执行任何操作。

key存在但不包含列表值时会返回错误。

返回值

整数回复:插入操作后列表的长度,或者未找到-1pivot

例子

redis>  RPUSH mylist "Hello" (integer) 1 

redis>  RPUSH mylist "World" (integer) 2 

redis>  LINSERT mylist BEFORE "World" "There" (integer) 3 

redis>  LRANGE mylist 0 -1 1) "Hello" 2) "There" 3) "World"
