Remove cache keys with key pattern

[xsoheilalizadeh]

Description

I have hybrid caching implemented on my system by using in-memory and redis provider, I want to be able to remove cache keys by a key pattern, for example, I have the following keys:

• configurations:games:ranks
• configurations:games:players

What I want to remove here is any key that includes games, so, I'd have a key pattern that looks like *games*

I tried to use IHybridCachingProvider.RemoveAsync which uses unlink command in redis, by using *games* as the key it would run the following command in redis that does not remove any keys:

unlink *games*

Then I wanted to try with IHybridCachingProvider.RemoveByPrefixAsync which uses scan to find the keys with the pattern that only ends with *, because it replaces the * in the pattern that I'm passing so *games* becomes games* that does not find the keys that I'm targetting.

scan 0 match games* count 200

Expected

The expected redis command that works for this issue is as following,

scan 0 match *games* count 200

The requirement here is to have a new method or any other solution to be able to remove keys by a pattern that is not limited by only a prefix. I'd be glad to contribute to this because it's a necessary feature for our project.

Specifications

• Provider : EasyCaching.HybridCache (1.6.1)
• Interceptor : AspectCore (6.0.0)
