bitfield:位图管道处理;bitfield有三个子指令,get、set、incrby,可以对指定位片段进行操作,单个指令最多只能处理64个连续位。 应用场景:用户签到、用户画像标签、大量整数排序等场景。 HyperLogLog 原理 伯努利实验:一次伯努利实验,抛硬币不管进行抛掷次数多少次,只要出现一个正面,就称之为为一次伯努利实验。

名称中包含 BIT 的命令,都是对二进制位的操作命令,例如,setbit、getbit、bitcount、bittop、bitfield,这些命令不常用。 15、典型应用场景 1)数据缓存:Redis 作为数据缓存层,MySQL 作为数据存储层。应用服务器首先从 Redis 中获取数据,如果缓存层中没有,则从MySQL 中获取后先存入缓存层再返回给应用服务器。 2)计...

Redis流(Stream):消息队列,还是用kafka消息队列(MQ,Message Queue)吧,kafka更专业。 Redis位域(bitfield,了解就好,工作中很少用):将很多小的证书存储到一个长度较大的位图中,又或者将一个非常庞大的键分割为多个娇小的键来进行存储,如实时分析领域。3
