RENAME key newkey

自1.0.0起可用。

时间严重年夜度: O(1)

重命名keynewkey。它key不存在时会前往弱点。假定newkey曾经存在,它将被笼罩,当发生这类情形时,RENAME 推行一个隐式的 DEL 操作,以是假定被删除的键网罗一个异常年夜的值,那么纵然 RENAME 自己通常是一个常量操作,也能够或许招致高延迟。

重视:在 Redis 3.2.0之前,假定源和目的称谓类似,则会前往弱点。

前往值

质朴字符串回复

例子

redis>  SET mykey "Hello" "OK" 

redis>  RENAME mykey myotherkey "OK" 

redis>  GET myotherkey "Hello"
