Delete All Keys #502

Open Edgaras91 opened 1 year ago

Edgaras91 commented 1 year ago

Description

How can I delete all keys with the correct prefix that was set up in set-up code. For example:

UseRedis( options => options.DBConfig.KeyPrefix = "dev1"

I want to delete all keys that have the above prefix "dev1" without having to mention the KeyPrefix.

I was very surprised that IEasyCachingProvider.RemoveAllAsync() requires keys? What is the use case to use this? Could we have an overload that doesn't take keys as parameters?

I also don't want to use "Flush" method as I believe that will ignore the prefix and require admin config.

The sole reason we are trying this library, as opposed to IDistributedCache, is so we can have a way to clear all cache for the application.

@Edgaras91 Thanks for your interest in this project.

You can have a try with RemoveByPatternAsync or RemoveByPrefixAsync

Could you give an example of how to do it? I could not find any good documentation on this. Our key has no structure. Star characters alone were rejected.

You can try to look at these unit test codes: https://github.com/easycaching-contrib/ec-basetest/blob/main/src/EasyCaching.BaseTest/BaseCachingProviderTest.cs#L929
