1.写入一段时间后duration过期 2.写入后刷新缓存 cacheLoader 3.重新加载方法reload 3.1 需要判断key不为空,原值oldValue不为空 3.2 基于immediateFuture实现,创建一个ListenableFuture,这个future不能被取消或者超时, 并且isDone方法永远会返回值 3.3 调用localCache中实现,传入Callable<? extends V> valueLoader执行加载...
CacheLoader.asyncReload(baseLoader,executor); asyncReloader.load(newObject()); asyncReloader.reload(newObject(),newObject()); asyncReloader.loadAll(ImmutableList.of(newObject())); assertEquals(2,loadCount.get()); assertEquals(1,reloadCount.get()); ...
线程安全:确保CacheLoader的load和reload方法是线程安全的,因为它们可能会被多个线程并发调用。 异常处理:在load和reload方法中处理可能的异常,以避免缓存处于不一致状态。 性能考虑:虽然异步重新加载可以提高响应性,但过多的异步任务可能会增加系统的负载。因此,需要合理设置缓存的容量和刷新策略。 缓存失效:如果缓存项在...
显式清除 任何时候，你都可以显式地清除缓存项，而不是等到它被回收： 个别清除：Cache.invalidate(key) 批量清除：Cache.invalidateAll(keys) 清除所有缓存项：Cache.invalidateAll() 移除监听器 通过CacheBuilder.removalListener(RemovalListener)，你可以声明一个监听器，以便缓存项被移除时做一些...
This is usually taken as a signal for the calling program to build the item. But if the entry has a CacheReloader, the Cache.get() method will use it to rebuild expired items rather than returning null. See Also: ReloadableCacheMethod Summary Object reload(String cacheName, Object key, ...
Returns a CacheLoader which wraps loader, executing calls to reload(K, V) using executor. static <K,V>CacheLoader<K,V>from(Function<K,V> function) Returns a cache loader that uses function to load keys, without supporting either reloading or bulk loading. static <V> Cache...

Some options and properties of plugin was not reloaded after :Lazy reload <plugin>, because the old version was preserved in cache. Sorry, something went wrong. fix(loader): when reloading, clear plugin properties cache … 8abfceb folke merged commit 312e424 into folke:main Oct 25, 202...
如selectOne、insert等）。转换过程可以参考MapperMethod的execute()方法实现。简单来说是以下规则：
The problem is that if you intend to stop the whole grid to restart it and reload the existing state from the CacheStore(s), the nodes get likely assigned a different position in the view, and therefore in the hashwheel, and the content of each local CacheStore won't match the ...
