Abstract
Настоящее изобретение предлагает способ и систему кэширования информационных объектов с помощью компьютерной сети. В данном изобретении механизм кэша непосредственно определяет, когда и где сохранять эти объекты в памяти (такой как ОЗУ) и в массовой памяти (такой как один или несколько накопителей на дисках), так чтобы оптимально записать эти объекты в массовой памяти и позже считать их из массовой памяти, без перманентного их поддержания. Механизм кэша активно распределяет эти объекты в память или на диск, определяет, где именно на диске сохранять эти объекты, извлекает эти объекты в ответ на ввод их идентификаторов в сети (таких как их URL - унифицированный указатель информационного ресурса) и определяет, какие объекты следует удалить из кэша, чтобы сохранять достаточное свободное пространство. Механизм кэша собирает информацию, предназначенную для записи на диск в форме эпизодов записи таким образом, чтобы максимально повысить эффективность при записи информации на диск и максимально повысить эффективность при последующем считывании информации с диска. Механизм кэша выполняет эпизоды записи таким образом, чтобы поэлементно вносить изменения на диске во время каждого эпизода записи, так что в механизме кэша не происходит сбоев из-за отключения питания или памяти, или иного промежуточного отказа узлов кэша. Механизм кэша сохраняет ключевые объекты системы на каждом из множества дисков, чтобы поддерживать голографию системы в том смысле, что потеря любого подмножества дисков уменьшает величину имеющегося кэша. Механизм кэша собирает также информацию, которую следует удалить с диска в ходе эпизодов удаления, чтобы максимальноThe present invention provides a method and system for caching information objects using a computer network. In this invention, the cache mechanism directly determines when and where to store these objects in memory (such as RAM) and in mass memory (such as one or more disk drives), so as to optimally record these objects in mass memory and later read them from mass memory, without permanent maintenance. The cache engine actively distributes these objects into memory or to disk, determines where to save these objects on disk, retrieves these objects in response to entering their identifiers in the network (such as their URL — a unified information resource pointer) and determines which objects follow remove from cache to save enough free space. The cache mechanism collects information intended for writing to disk in the form of recording episodes in such a way as to maximize efficiency when writing information to a disk and maximize efficiency when subsequently reading information from a disk. The cache engine performs episodes of recording in such a way as to make changes on the disk element by element during each episode of recording, so that the cache mechanism does not fail due to power or memory outage or other intermediate failure of cache nodes. The cache mechanism stores key system objects on each of a variety of disks in order to maintain system holography in the sense that the loss of any subset of disks reduces the size of the existing cache. The cache engine also collects information that should be removed from the disk during deletion episodes in order to maximize
