摘要： An application deployment model for enterprise applications to enable applications to be deployed to and executed from a globally distributed computing platform, such as an Internet content delivery network (CDN). According to the invention, application developers separate their Web application into two layers: a highly distributed edge layer and a centralized origin layer. In a representative embodiment, the edge layer supports a servlet container that executes a Web tier, typically the presentation layer of a given Java-based application. Where necessary, the edge layer communicates with code running on an origin server to respond to a given request. In an alternative embodiment, the edge layer supports a more fully-provisioned application server that executes both Web tier (e.g., presentation) and Enterprise tier application (e.g., business logic) components. In either case, the inventive framework enables one or more different applications to be deployed to and executed from the edge server on behalf of one or more respective entities.

摘要： The present invention provides a method for obtaining predicable and repeatable output results in a continuous processing system. The method involves processing messages and primitives in accordance with the following rules: (1) Messages are processed in accordance with timestamps, where messages are divided up into “time slices”; (2) message order within a data stream is preserved among messages with the same time stamp; (3) subject to rule #4, for each time slice, a primitive is executed when either the messages within such time slice show up in the input stream for such primitive or the state of the window immediately preceding such primitive changes due to messages within such time slice; and (4) for each time slice, primitives that are dependent on one or more upstream primitives are not executed until such upstream primitives have finished executing messages in such time slice that are queued for processing. If such rules are insufficient to determine the order in which primitives are processed, a deterministic “tie-breaking” rule is then applied.

摘要： A method for processing messages ensures that every message that enters a continuous processing system is fully processed in its entirety, even in the event of a failure within the system. Messages are pushed through an execution plan that includes a set of connected “primitives” that process the message, where the primitives may be distributed across a group of servers. Messages are pushed through in accordance with a protocol that does not permit unprocessed messages to be permanently lost as they travel from input sources, between primitives, and to output sources within the execution plan. The input queue, output queue, and state (if any) associated with each primitive are saved in persistent storage at select checkpoints. If a failure occurs on a server, the server, after it starts up again, restores the primitives on that server to the input queues, output queues, and states saved at the last applicable checkpoint.

摘要： A method is provided for processing an application on an edge server, wherein the application comprises a set of defined presentation, code and data components, each of which are preferably URI-addressable objects. In response to a client request, the presentation, code and data components are processed according to a set of metadata to generate a response, and the response is delivered to the client. The presentation components are typically content such as HTML fragments, WML fragments, or some combination thereof. The code components are typically Java servlets or beans, XSLT style sheets, or some combination thereof. The data components are typically XML files, native database formatted files, and the like. Each of the presentation, code and data components may have a distinct management profile, cacheability profile, deployment profile, invalidation profile, and security profile. These profiles are settable via metadata or other similar means. Using this framework, heterogenous components may be composed into other components and complete applications or services.

摘要： A method, in a continuous computation system, for processing a set of registered queries over a cluster of servers includes creating an execution plan for processing a set of queries over a cluster of servers, where the continuous computation system creates the execution plan by analyzing the semantics and requirements of the queries to determine how to distribute processing across the cluster. Analysis of a query can include determining whether input messages for the query can be processed independent of each other, whether input messages for the query can be partitioned into groups that can be processed independent of each other, whether the query includes an aggregator function, and whether the query includes a subquery.

摘要： Business applications running on a content delivery network (CDN) having a distributed application framework can create, access and modify state for each client. Over time, a single client may desire to access a given application on different CDN edge servers within the same region and even across different regions. Each time, the application may need to access the latest “state” of the client even if the state was last modified by an application on a different server. A difficulty arises when a process or a machine that last modified the state dies or is temporarily or permanently unavailable. The present invention provides techniques for migrating session state data across CDN servers in a manner transparent to the user. A distributed application thus can access a latest “state” of a client even if the state was last modified by an application instance executing on a different CDN server, including a nearby (in-region) or a remote (out-of-region) server.

摘要翻译： 在具有分布式应用程序框架的内容传送网络（CDN）上运行的业务应用程序可以为每个客户端创建，访问和修改状态。 随着时间的推移，单个客户端可能希望访问同一区域内甚至跨不同区域的不同CDN边缘服务器上的给定应用。 每次应用程序可能需要访问客户端的最新“状态”，即使该状态最后被不同服务器上的应用程序修改。 当最后修改状态的过程或机器死亡或临时或永久不可用时，会出现困难。 本发明提供了以对用户透明的方式跨CDN服务器迁移会话状态数据的技术。 因此，分布式应用程序可以访问客户端的最新“状态”，即使状态最后由在不同的CDN服务器上执行的应用程序实例进行修改，包括附近（区域内）或远程（区域外） 服务器。
