How delete special db cache

Hi
My Codeigniter version is 3
I cache some query with $this-db->cache
But the bad event is caches saved with segment and if I want to delete special query, I have to delete all cache
For example, I have a function for getting user info with id 1 or 2 or 3
I cache query for each user
When user 1 modify his profile, so I have to delete the cache for only user 1, not all cache
Please help me how to do it

The only thing you might try is the db delete that only deletes the cache for that page.

Not the delete all one.

What did you Try? What did you Get? What did you Expect?

I know but I have many functions and I need only remove special function cache

You can not do it with the db cache, with the file cache you can name it and then delete it.
Sounds like it would be a good method to add to the db cache.

I want to use Redis instead of DB cache
But cannot install it on windows wamp
My PHP version is 7.4.2
Can you help me with it?
