摘要： A distributed storage system is provided. The distributed storage system includes multiple front-end servers and zones for managing data for clients. Data within the distributed storage system is associated with a plurality of accounts and divided into a plurality of groups, each group including a plurality of splits, each split being associated with a respective account, and each group having multiple tablets and each tablet managed by a respective tablet server of the distributed storage system. Data associated with different accounts may be replicated within the distributed storage system using different data replication policies. There is no limit to the amount of data for an account by adding new splits to the distributed storage system. In response to a client request for a particular account's data, a front-end server communicates such request to a particular zone that has the client-requested data and returns the client-requested data to the requesting client.

摘要： The present invention is directed to a client-server network system implementing a multi-tier caching strategy for a user to access a document efficiently. The system comprises a client cache assistant serving as proxy for web browsers, a remote cache server managing user-requested documents and a search engine repository storing a huge number of documents as a backup for the remote cache server. Upon receipt of a document request, the client cache assistant examines its client cache to identify the requested document. If not successful, the remote cache server then identifies a copy of the requested document in its own cache and transmits a content difference between the two copies to the client cache assistant. If the server copy is still not fresh or not found, the remote cache server seeks another copy of the requested document from the search engine repository and transmits another content difference to the client cache assistant. The client cache assistant merges the content differences and the original copy into a new copy of the requested document.

摘要： Upon receipt of a document request, a client assistant examines its cache for the document. If not successful, a server searches for the requested document in its cache. If the server copy is still not fresh or not found, the server seeks the document from its host. If the host cannot provide the copy, the server seeks it from a document repository. Certain documents are identified from the document repository as being fresh or stable. Information about each these identified documents is transmitted to the server which inserts entries into an index if the index does not already contain an entry for the document. If and when this particular document is requested, the document will not be present in the server, however the server will contain an entry directing the server to obtain the document from the document repository rather than the document's web host.
摘要翻译：在接收到文档请求时，客户端助理检查其文件的缓存。如果不成功，服务器将在其缓存中搜索所请求的文档。如果服务器副本仍然不新鲜或找不到，则服务器从其主机寻找文档。如果主机无法提供副本，则服务器从文档存储库中查找它。某些文件从文档库中确定为新鲜或稳定。关于每个这些标识的文档的信息被传送到服务器，如果索引还没有包含文档的条目，则将该条目插入到索引中。如果请求此特定文档时，该文档将不存在于服务器中，但是服务器将包含一个条目，指示服务器从文档存储库而不是文档的Web主机获取文档。

摘要： An example method for passive compaction of a cache includes determining first metadata associated with first data and second metadata associated with second data. The first metadata includes a first retrieval time, and the second metadata includes a second retrieval time. The example method further includes obtaining a first metadata key including a first unique identifier and obtaining a second metadata key including a second unique identifier. The example method also includes generating a first data key and generating a second data key. The example method further includes writing, at a client device, the first and second data to the cache. Each of the first and second data occupy one or more contiguous blocks of physical memory in the cache, and the first and second data are stored in the cache in an order based on the relative values of the first and second retrieval times.
摘要翻译：用于缓存的被动压缩的示例性方法包括确定与第一数据相关联的第一元数据和与第二数据相关联的第二元数据。第一元数据包括第一检索时间，第二元数据包括第二检索时间。该示例方法还包括获得包括第一唯一标识符的第一元数据密钥并获得包括第二唯一标识符的第二元数据密钥。该示例方法还包括生成第一数据密钥并生成第二数据密钥。该示例方法还包括在客户端设备处将第一和第二数据写入高速缓存。第一和第二数据中的每一个占据高速缓存中的一个或多个物理存储器的连续块，并且第一和第二数据以基于第一和第二检索时间的相对值的顺序存储在高速缓存中。
