WebApr 7, 2024 · When you look up a value by key, the cache first checks the map to see if such a value exists. If not, it relies on a loader to load the value from a data source in read-through manner and enters the value into the map using a put-if-absent method. The challenge in ensuring high throughput lies in efficient maintenance of the LRU list.
