Redis根据通配符批量删除Key
Redis 目前还不支持根据通配符批量删除 Key 的命令，但我们可以借助 Redis 的 del 命令、Linux 管道和 xargs 指令来完成。
Redis的
del命令支持删除给定的一个或多个 key，并返回被删除 key 的数量。如命令del key1 key2 key3。
比如要删除所有以 WxMpSessionKey 开头的 Key，可以使用如下命令：
1 | [redis@iztz9ploifbvce ~]# redis-cli -h 192.168.182.227 -p 1379 keys "WxMpSessionKey*" |xargs redis-cli -h 192.168.182.227 -p 1379 del |
如果连接 Redis 的 HOST 为 127.0.0.1，端口号也为默认的 6379，则以上的命令可以简写为：
1 | redis-cli keys "WxMpSessionKey*" |xargs redis-cli del |
（END）

Using the PFADD Command in Redis
Redis, an open-source, in-memory data structure store, offers a wide range of commands to manipulate data structures like strings, lists, sets, hashes, bitmaps, hyperloglogs, and more. Among these, the HyperLogLog data type is particularly useful for approximating the number of unique elements in a set when the set is too large to fit into memory or when you don’t need absolute accuracy. The PFADD command is one of the key operations for working with HyperLogLog in Redis. This guide will...
