Redis obtains hash key data in batches

Since user information is cached in the redis hash type

The requirement is to obtain a user list, such as 30 users on each page, and want to obtain the user information of these 30 users at one time
But redis does not obtain hash keys in batches Methods!
How should I solve it? Is there something wrong with my design?
For example, the user hash key is userinfo:1 user:info:2 user:info:3 user:info:4 ....
These hash keys store user information
I want to get the hash value of userinfo:1-30 at one time

Use lua script to loop
eval "local rst={}; for i,v in pairs(KEYS) do rst[i]=redis.call('hgetall', v) end; return rst" 2 user:1 user :2

127.0.0.1:6379> hgetall user:2
1) "age"
2) "22"
3) "name"
4) "tom"
127.0.0.1:6379> hgetall user:1
1) "name"
2) "jack"
3) "age"
4) "21"

Use lua, or multi

In my case it’s just a for loop, multi is a transaction
