摘要： State information in a publish and subscribe system is retained. A state publication is received from a publisher for a topic with one or more delta publications. The state publication and the one or more delta publications are used to keep track of a current state associated with the topic. It is determined that a subscriber has connected to a topic and information pertaining to the current state is sent to the subscriber. This equates to either a list comprising the state publication and subsequent delta publications or a single publication. Such a single publication is maintained by the system and comprises a state publication updated by one or more subsequent delta publications.

摘要翻译： 保留发布和订阅系统中的状态信息。 从一个发行者收到一个国家出版物，为一个或多个三角洲出版物提供主题。 国家出版物和一个或多个增量出版物用于跟踪与该主题相关联的当前状态。 确定订户已经连接到主题，并且将关于当前状态的信息发送给订户。 这等同于包括国家出版物和随后的增量出版物或单个出版物的列表。 这样的单个出版物由系统维护并且包括由一个或多个后续的delta出版物更新的状态发布。
