memcached

The MinSendBackupAfterMs is now set to 1 ms. Unfortunately this causes backup requests to be send when there is low load. It would be useful if we could set the minimum a little bit higher for certain endpoints.

Currently we don't have any mechanism to limit the maximum number of clients that could be handled simultaneously.

This feature should be designed properly. Here is some clue: https://redis.io/topics/clients#maximum-number-of-clients

Seem we need RemoveAll cache with out parameter, or can called by remove everything for invalidate all cache.

For now I use following code

var listPrefix = new List<string>
{
    "foo",
    "bar",
    "another-foo"
};

listPrefix.ForEach(prefix => {
   cachingProvider.RemoveByPrefix(prefix);
});

Instead of write above code, we may can write single like below

` cachin

建议BaseRepository 里增加返回 IQueryable 的Get / GetAsync 的方法
有了之后就可以在service 里面进行拼接LINQ 用于获取到ViewModel中关联其他类的数据

Steps to reproduce:

1. I have about 5 millions of items in Redis.
2. Call cache.clear() without arguments.

As a temporary workaround I had to call redis-cli FLUSHALL from terminal.

Get能否类似post设置request Header,现在貌似没有提供
