Semantic method and device based on message middleware

Abstract

The invention discloses a semantic method and device based on message middleware, and the method comprises the steps: obtaining a semantic identifier in a semantic request under the condition that the semantic request for the message middleware is received; determining a target semantic method based on the semantic identifier, wherein the target semantic method is a semantic method based on an idempotent principle or a semantic method based on a transaction principle; under the condition that the target semantic method is the semantic method based on the idempotent principle, executing the semantic method only once on a single message queue in the semantic request based on the message middleware; and under the condition that the target semantic method is the semantic method based on the transaction principle, executing the semantic method only once on the plurality of message queues in the semantic request based on the message middleware. According to the process, the semantic method is executed only once based on the idempotent principle or the transaction principle, semantic guarantee is not needed to be carried out only once based on an additional streaming data computing platform, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data flow computing, in particular to a semantic method and device based on message middleware. Background technique [0002] In stream computing systems, messages have different semantics. There are three general semantics: [0003] at-most-once: At most once, do not care whether the message is sent successfully, and do not need the return value of the message sent. (Can be lost, such as request logs and other scenarios) [0004] at-least-once: at least once, allowing the message to repeat but must ensure that the message must arrive. (It can be repeated, such as video information, modified N times, the latest shall prevail) [0005] exactly-once: Exactly once, to ensure that the message will not be lost and will not be repeated. (There is and can only be used once, such as payment, transfer and other scenarios that need to rely on context calculations) [0006] At most, the existing message middle...

Problems solved by technology

And the processing of related semantics is handed over to the corresponding producers and consumers to guarantee the exactly-once semantics based on the additional stream data computing platform, and deal with the problem of low efficiency.
