cached state

基本解释

Cached state can optionally be indexed, allowing the entire grid to be searched.
我们可以对缓存状态加索引，这样就能搜索整个网格了。
This would typically happen in parallel, as each node receives and performs the query on its locally cached state. And returns results.
通常这都是并发行为，因为每个结点都会在其本地的缓存状态上接收并执行查询，最后返回结果。
The forecast is retrieved from the NWS if the NWS is online and from a file if it is not online, and the method uses the cached state and city information to improve performance.
在 NWS 在线的情况下从 NWS 检索预报，在 NWS 不在线的情况下从文件中检索预报，该方法使用高速缓存的州和城市信息以提高性能。
