    • Dynamic application instance discovery and state management within a distributed system. A distributed system may implement application instances configured to perform one or more application functions within the distributed system, and discovery and failure detection daemon (DFDD) instances, each configured to store an indication of a respective operational state of each member of a respective group of the number of application instances. Each of the DFDD instances may repeatedly execute a gossip-based synchronization protocol with another one of the DFDD instances, where execution of the protocol between DFDD instances includes reconciling differences among membership of the respective groups of application instances. A new application instance may be configured to notify a particular DFDD instance of its availability to perform an application function. The particular DFDD instance may be configured to propagate the new instance's availability to other DFDD instances via execution of the synchronization protocol, without intervention on the part of the new application instance.
    • 动态应用程序实例发现和分布式系统中的状态管理。 分布式系统可以实现被配置为在分布式系统内执行一个或多个应用功能的应用实例,以及发现和故障检测守护程序(DFDD)实例,每个实例被配置为存储相应组的每个成员的相应操作状态的指示 应用程序实例的数量。 DFDD实例中的每一个可以与DFDD实例中的另一个重复地执行基于八卦的同步协议,其中DFDD实例之间的协议的执行包括协调各个应用实例组的成员之间的差异。 可以将新的应用实例配置为通知特定的DFDD实例其可用性来执行应用功能。 特定DFDD实例可以被配置为通过执行同步协议将新实例的可用性传播到其他DFDD实例,而不需要新应用实例的部分干预。

    • Method and apparatus for measuring true end-to-end latency for calls to Web services are described. In embodiments, a Web service client and a Web service provider may collaborate to collect timing/latency data for calls to the Web service. This data may be collected, stored, and analyzed by a latency measurement service to generate displays and/or reports on true end-to-end latency measurements for Web service calls. Embodiments may collect Internet/network infrastructure latency for Web service calls up to and including the “last mile” to the Web service client and the Web service processing time. Additionally, by analyzing latency data collected from a number of Web services clients and/or Web service providers, embodiments may provide a macro-level view into overall Internet performance. In one embodiment, the latency measurement service may be a Web service.
    • 描述了用于测量对Web服务调用的真实端到端延迟的方法和装置。 在实施例中,Web服务客户端和Web服务提供商可以协作来收集用于对Web服务的呼叫的定时/等待时间数据。 可以通过延迟测量服务收集,存储和分析此数据,以生成Web服务调用的真实端到端延迟测量的显示和/或报告。 实施方式可以收集到Web服务客户端的Web服务呼叫直到并包括“最后一公里”的Web /网络基础架构延迟以及Web服务处理时间。 此外,通过分析从多个Web服务客户端和/或Web服务提供商收集的延迟数据,实施例可以将宏观级视图提供到整体的互联网性能。 在一个实施例中,等待时间测量服务可以是Web服务。

    • A keymap service architecture for a distributed storage system. A system may implement storage nodes configured to store replicas of data objects, where each of the replicas is accessible via a respective locator value, and keymap instances each configured to store keymap entries corresponding respectively to the data objects. A given keymap entry may indicate a mapping from a given key value corresponding to a given data object to each respective locator value of its replicas. Each of the keymap instances may store a replica of the given keymap entry and may index its respective stored keymap entries within a respective index data structure including hierarchically arranged index nodes corresponding to keymap entries. For a given keymap entry having a given corresponding index node, each tag value associated with each ancestor of the given corresponding index node may be a prefix of the given key value.
    • 分布式存储系统的键盘映射服务体系结构。 系统可以实现被配置为存储数据对象的副本的存储节点,其中每个副本可以经由相应的定位器值访问,以及键映射实例,其被配置为存储分别对应于数据对象的键映射条目。 给定的键映射条目可以指示对应于给定数据对象的给定键值到其副本的每个相应定位器值的映射。 每个键映射实例可以存储给定键映射条目的副本,并且可以在相应的索引数据结构内对其各自存储的键映射条目进行索引,包括对应于键映射条目的分层排列的索引节点。 对于具有给定对应索引节点的给定键图条目,与给定对应索引节点的每个祖先相关联的每个标签值可以是给定键值的前缀。
