摘要： A method for uploading an object into a distributed storage system is implemented at a computing device The computing device splits an object into one or more chunks and uploads the one or more chunks into the distributed storage system. For each uploaded chunk, the computing device receives a write token from the distributed storage system, inserts an entry into an extents table of the object for the chunk in accordance with the received write token and the chunk ID, chunk offset, and chunk size of the chunk, generates a digest of the extents table, the digest representing the one or more chunks that the client expects to be within the distributed storage system, and sends the digest of the extents table to the distributed storage system. The distributed storage system is configured to use the digest to determine whether it has each of the one or more client-expected chunks.

摘要翻译： 一种将对象上传到分布式存储系统的方法在计算设备上实现。计算设备将对象分成一个或多个块，并将一个或多个块上传到分布式存储系统中。 对于每个上传的块，计算设备从分布式存储系统接收写令牌，根据接收到的写令牌和块ID，块偏移量和块大小将条目插入到块的对象的扩展表中 块，生成扩展表的摘要，摘要表示客户端期望在分布式存储系统内的一个或多个块，并将扩展数据表的摘要发送到分布式存储系统。 分布式存储系统被配置为使用摘要来确定它是否具有一个或多个客户预期的块中的每一个。

摘要： A structured document is translated into an initial hierarchical data structure in accordance with syntactic elements defined in the structured document. The initial hierarchical data structure includes a plurality of nodes, and each node corresponds to one of the syntactic elements. The method then annotates a node with a set of attributes including geometric parameters of semantic elements in the structured document that are associated with the node in accordance with a pseudo-rendering of the structured document. Finally, the method merges the nodes in the initial hierarchical data structure into a tree of merged nodes in accordance with their respective attributes and a set of predefined rules such that each merged node is associated with a semantically distinct region of the pseudo-rendered document. The predefined rules include rules for merging nodes associated with semantic elements that have nearby positions and/or compatible attributes in the pseudo-rendered document.

摘要翻译： 结构化文档根据结构化文档中定义的句法元素被翻译成初始分层数据结构。 初始层次数据结构包括多个节点，并且每个节点对应于语法元素之一。 该方法然后根据结构化文档的伪呈现，利用一组属性来注释节点，包括与该节点相关联的结构化文档中的语义元素的几何参数。 最后，该方法根据其各自的属性和一组预定义的规则将初始分层数据结构中的节点合并到合并树的树中，使得每个合并的节点与伪呈现的文档的语义上不同的区域相关联。 预定义规则包括用于合并与伪渲染文档中具有附近位置和/或兼容属性的语义元素相关联的节点的规则。
