    • A method and system for providing convergence of data copies in asynchronous data replication in a database system, includes: labeling rows of a plurality of table copies with a monotonic number, a copy identification, and propagation controls; asynchronously capturing at least one labeled change to any row of any of the plurality of table copies from a database recovery log; determining that the captured change is to be communicated to others of the plurality of table copies; communicating the captured change to the others of the plurality of table copies; and applying the communicated change to the others of the plurality of table copies, where the plurality of table copies converge to a same state. In applying the communicated changes, conflicting changes are identified and resolved. In this manner, convergence of data copies in asynchronous data replication is provided, and processing and storage costs are significantly reduced.
    • 一种用于在数据库系统中异步数据复制中提供数据副本的收敛的方法和系统,包括:用单调数,复制标识和传播控制标记多个表副本的行; 从数据库恢复日志中异步地将至少一个标记的更改捕获到多个表副本中的任一个的任何行的任何行; 确定所捕获的改变将被传送到所述多个表副本中的其他人; 将所捕获的改变传达给所述多个表格副本中的其他更改; 以及将所传送的改变应用于所述多个表副本中的其他表,其中所述多个表副本收敛到相同的状态。 在应用传达的更改时,会发现和解决冲突的变化。 以这种方式,提供异步数据复制中的数据副本的收敛,并且显着地减少处理和存储成本。

    • One or more techniques and/or systems are disclosed for providing additional content in an email. An email service can receive the email at an email server. Prior to the email being sent to an email client, metadata for a parameter used to retrieve the additional content is identified and collected. The collected metadata is sent to the email client used by the intended recipient of the email (e.g., on a smart phone). When the user attempts to access the email, the email server can respond by sending script code to the email client, which, in combination with locally stored metadata retrieved from the email, provides the additional content in the email. In this manner, an email regarding a package, for example, can include not only a tracking number but also a status of the delivery of the package, where the status may be different/updated each time the email is accessed.
    • 公开了用于在电子邮件中提供附加内容的一个或多个技术和/或系统。 电子邮件服务可以在电子邮件服务器上接收电子邮件。 在将电子邮件发送到电子邮件客户端之前,识别并收集用于检索附加内容的参数的元数据。 收集的元数据被发送到电子邮件的预期收件人使用的电子邮件客户端(例如,在智能电话上)。 当用户尝试访问电子邮件时,电子邮件服务器可以通过向电子邮件客户端发送脚本代码来进行响应,电子邮件客户端与本地存储的从电子邮件检索的元数据结合在电子邮件中提供附加内容。 以这种方式,例如,关于包裹的电子邮件不仅可以包括跟踪号码,而且还可以包括每次接入电子邮件时状态可能不同/更新的包裹的传送状态。

    • One or more techniques and/or systems are disclosed for virtualizing data in a user interface (UI). A virtual layout viewport is identified which comprises an area that may be viewed in a UI, where at least some data from one or more tuples of data is to be realized in the viewable area of the UI. Data that is to be realized in the viewport is identified from the one or more tuples of data, and the identified data is realized in the viewport, such as by creating a representation of the data for display in the UI. The realized data can be virtualized by removing the representation when the virtual layout viewport is modified in relation to a display of tuple data (e.g., an item is scrolled out of view).
    • 公开了用于在用户界面(UI)中虚拟化数据的一个或多个技术和/或系统。 识别虚拟布局视口,其包括可以在UI中观看的区域,其中来自一个或多个数据元组的至少一些数据将在UI的可见区域中实现。 要在视口中实现的数据是从一个或多个数据元组中识别的,并且识别的数据在视口中实现,例如通过创建用于在UI中显示的数据的表示。 当虚拟布局视口相对于元组数据的显示被修改(例如,一个项目被滚出视图)时,通过去除表示来实现所实现的数据。

    • A method for handling transaction messages in asynchronous data replication in a database system, in which the database system includes a source node and a target node, and each transaction message has information concerning a row change to a table copy at the source node. The method includes determining whether a first transaction message has a dependency on a preceding non-completed transaction message. Responsive to the first transaction message having a dependency on the preceding non-completed transaction, the method further includes holding the first transaction message, completing the preceding non-completed transaction message including applying the row change associated with the preceding non-completed transaction message to the table copy at the target node, and responsive to completing the preceding non-completed transaction message, releasing the first transaction message and applying the row change associated with the first transaction message to the table copy at the target node.
    • 一种用于在数据库系统中处理异步数据复制中的事务消息的方法,其中数据库系统包括源节点和目标节点,并且每个事务消息具有关于在源节点处的表副本的行更改的信息。 该方法包括确定第一交易消息是否具有对先前未完成的交易消息的依赖性。 响应于对先前未完成的交易具有依赖性的第一交易消息,该方法还包括保存第一交易消息,完成前述未完成交易消息,包括将与先前未完成的交易消息相关联的行变更应用于 在目标节点处的表副本,并且响应于完成上述未完成的交易消息,释放第一交易消息并将与第一交易消息相关联的行变更应用于目标节点处的表副本。
