> The release logic here is reasonable, as release is usually called in conjunction with insert or lookup: > > 1. `lookup + release` will not increase the cache usage. > > 2. ` insert + release`, if `_usage + current_item_total_size > _capacity` during the insert, there will trigger the eviction of infrequently used items. If no existing items are evicted during the insert, it means that all items in the current cache are hot. In this case, it is reasonable to throw away the item to be inserted during release, to prevent the cache usage from increasing infinitely in the case of all hot data.
