Hello! Previously, I practically did not work with radish. The question is this: there are many entries in the database like user:1:followers, user:2:followers, and so on. How do I efficiently reset the values of all such keys to null? So that user:1:followers = user:2:followers = ... = 0
Is it possible to write something like SET user:*:followers 0?
In addition to followers, friends must also be reset. Can these operations be combined somehow?

You can scan the keys with the SCAN command with an asterisk in the template and reset the values using the found keys with the MSET command.
If it is possible with one team, I will be glad to know too.
