Redis 列表

Redis 列表简介

Redis 列表是字符串值的链表。Redis 列表经常用于

• 实现堆栈和队列。
• 为后台工作系统构建队列管理。

基本命令

• LPUSH 将新元素添加到列表头部；RPUSH 将新元素添加到列表尾部。
• LPOP 移除并返回列表头部的一个元素；RPOP 执行相同操作但从列表尾部移除。
• LLEN 返回列表的长度。
• LMOVE 原子地将元素从一个列表移动到另一个列表。
• LRANGE 从列表中提取一系列元素。
• LTRIM 将列表截断到指定的元素范围。

阻塞命令

列表支持几种阻塞命令。例如

• BLPOP 移除并返回列表头部的一个元素。如果列表为空，该命令将阻塞，直到有元素可用或达到指定的超时时间。
• BLMOVE 原子地将元素从源列表移动到目标列表。如果源列表为空，该命令将阻塞，直到有新元素可用。

参阅完整的列表命令系列。

示例

• 将列表视为队列（先进先出）

  >_ Redis CLI

  > LPUSH bikes:repairs bike:1
  (integer) 1
  > LPUSH bikes:repairs bike:2
  (integer) 2
  > RPOP bikes:repairs
  "bike:1"
  > RPOP bikes:repairs
  "bike:2"

• 要限制列表的长度，可以调用 LTRIM

  >_ Redis CLI

  > RPUSH bikes:repairs bike:1 bike:2 bike:3 bike:4 bike:5
  (integer) 5
  > LTRIM bikes:repairs 0 2
  OK
  > LRANGE bikes:repairs 0 -1
  1) "bike:1"
  2) "bike:2"
  3) "bike:3"
