这是直写式缓存的变体之一，称为写无效策略。通常，实现纯粹的回写式缓存没有多大意义，因为它既耗时又缓慢。但如果我们将 write-around 模式与cache-aside或read-through模式结合使用，那就有意义了。原因是：假设我们有一些不会很快被读取的数据。在这种情况下，我们永远不希望此类数据的写入经过缓存。由于缓存通常具

This post explains the three basic cache writing policies: write-through, write-around and write-back. Although caching is not a language-dependent thing, we’ll use basic Python code as a way of making the explanation and logic clearer and... | Shahriar
The processing signals determine when the data stored in the write buffer is also stored in the cache, and, therefore, the cache is permitted to read- around the write buffer more than one time as long as the write buffer has the same data stored therein as exists in the cache....
