Question

If you know that the cache will be invalidated because of an explicit Service call in real time, it's pretty easy. Just kill the cache. It might be expensive to recreate it, though, or perhaps you even know exactly what needs to be refreshed.

这句话太难了，我快疯了。什么破英语写的。
作者脑子有问题。

如果清楚会使快存失效的具体实时调用服务，这就易如反掌。只要取消快存即可。即便你清楚要刷新的内容，重建快存也可能代价不菲。
