A messaging system supporting SQL syntax

Abstract

The invention discloses a message system supporting SQL syntax. The message system is a message middleware, as a kind of middleware, has the characteristics of shielding the differentiation of the underlying services, and provides a unified and easy-to-use interface for external users to receive and send messages, thus shielding the details of the underlying. Generally speaking, consumers and senders of messages have the ability to process messages, and the message middleware that supports SQL syntax has the additional middleware-level processing power for the message itself. By combining withthe high performance of middleware layer and powerful decoupling characteristics, the message system based on SQL syntax will have instant filtering of messages and the ability to add, delete and modify configuration messages, which can be used as redundant backup to ensure data integrity or customize stronger and more powerful API to support the high-availability extension of message middleware.

Description

technical field [0001] The present invention relates to a client of a message system (hereinafter also referred to as message middleware) that supports SQL syntax, and the corresponding middleware supporting technology. It is easy to refer to the field of data processing and integration, especially related to DQL (Data Query Language) related supporting technology . Background technique [0002] The role of message middleware is to achieve the underlying technology that supports horizontal expansion and decoupling of services through the routing and distribution of messages. Clients developed based on message middleware technology often need to consider a series of issues around the reliability of messages, such as how to cache important messages and message landing, and these often make service construction cumbersome, and message users need to subscribe to many messages. And filter the messages by yourself, and then store data around the messages that need to be landed. M...

Problems solved by technology

First of all, such an operation is more complicated, and secondly, the load on the middleware is relatively large. If many people subscribe to this topic, many repeated and redundant messages will be generated, which creates double pressure on the message source and middleware.
