SYSTEM FOR HIGH-THROUGHPUT HANDLING OF TRANSACTIONS IN DATA-PARTITIONED, DISTRIBUTED, RELATIONAL DATABASE MANAGEMENT SYSTEM

摘要

The present invention is directed to a novel, a topic-based messaging architecture (including schema, protocols, naming conventions, etc.) to be used in a distributed data-oriented OLTP environment. According to an aspect of the claimed subject matter, the topic-based messaging architecture can be implemented as a type of publication-subscription (pub-sub) messaging pattern. In one or more embodiments of the topic-based system, messages are published to topics, or named logical channels. Subscribers in a topic-based system will receive all messages published to the topics to which they subscribe, and all subscribers to a topic will receive the same messages. The publisher is responsible for defining the classes of messages to which subscribers can subscribe. The topic-based messaging interface improves the scalability of a distributed database management system and provides a robust mechanism for message delivery.
