简介

  • Redis Sorted Set / Zset（有序集合）
  • 命令特征：所有命令开始前都带有字母“Z”

    增加

    | 命令 | 解释 | | —- | —- | | ZADD key [NX|XX] [CH] [INCR] score member [score member …] | 添加到有序set的一个或多个成员，或更新的分数，如果它已经存在 | | ZINCRBY key increment member | 增量的一名成员在排序设置的评分 |

删除

命令 解释
ZREMRANGEBYLEX key min max 删除名称按字典由低到高排序成员之间所有成员。
ZREMRANGEBYRANK key start stop 在排序设置的所有成员在给定的索引中删除
ZREMRANGEBYSCORE key min max 删除一个排序的设置在给定的分数所有成员

查询

命令 解释
ZCARD key 获取一个排序的集合中的成员数量
ZCOUNT key min max 返回分数范围内的成员数量
ZLEXCOUNT key min max 返回成员之间的成员数量
ZRANGE key start stop [WITHSCORES] 根据指定的index返回，返回sorted set的成员列表

修改

命令 解释
