Redis How to limit the return number of a KEYS command?

Question

I get values ​​with the "KEYS p_ *" command in redis.

But with "KEYS p_ *", if redis has millions of keys, I will get too many values ​​and poor performance.

So, can I just get 100 values ​​with the "KEYS p_ *" command?

Answer 1

SCAN is recommended for production, so you can use something like:

SCAN 0 COUNT 100 MATCH p_* 

and keep getting the next page
see the SCAN command for more details:
