Question 121528 in Redis Question posted in
The official documentation can be found here.

How to clear the key in the specified list in Redis?

Redis has the following data:

key         value
code1       num1
code2       num2
...
code6000000 num6000000

I have a known fixed list which is not regular：

{code1, code3, code11, ..., code1234567}

How should I design Redis so that I can easily delete these kv?

    Redis has a data structure like hash table this.

    you can easily follow instructions there to accomplish your needs.

    Example:

    redis:6379> HSET myhash field1 "Hello"
(integer) 1

redis:6379> HGET myhash field1
"Hello"

redis:6379> HDEL myhash field1
(integer) 1

    if you want to delete some keys that are stored in a Redis list, you can use this one line shell script in Linux:

    > redis-cli  LRANGE mylist 0 -1 | xargs redis-cli  DEL
