Toward a General Distributed Messaging Framework for Online Transaction Processing Applications

Abstract

This paper presents a general distributed messaging framework for online transaction processing applications in e-business industry, and we name it as Metamorphosis (MetaQ). Specifically, this messaging framework has features of high availability, scalability, and high data throughput. The current implementation of MetaQ supports distributed XA transactions, asynchronous messaging, and multiple ways for storing message offsets. As a consequence, it is suited to the application contexts having a large quantity of messages, transaction-support, and real-time requirements. More important, another branch of MetaQ implementation, i.e., RocketMQ has been deployed and used in Taobao.com and Alipay.com. The real usages in both typical online transaction applications have proven that the nature of MetaQ can perform well for such big Internet applications.
