Implementation method of queue for processing declarative events

Abstract

The invention relates to the field of cloud platform event processing, in particular to an implementation method of a queue for processing declarative events, which comprises the following steps of: S1, creating a queue, checking by a de-weighting device before the events are added into the queue, and only allowing the events which do not exist to be added into the queue by the de-weighting device; S2, arranging a plurality of events in the queue in a stacking manner according to a priority sequence; S3, controlling a processor to obtain the frequency of the event from the queue through a speed governor; and S4, the processor carrying out state transition processing on the event, wherein if processing succeeds, references to the event in the de-weighting device are eliminated, state transition processing of the next event is carried out, and if processing fails, the event which fails to be processed by the processor is added into the de-weighting device again after failure times are recorded by the back-off device, the priority is lowered and the processing time is delayed. The problems of repeated processing, overload processing and concurrent processing of normal events of failure events due to the fact that failure event return queues serve as the normal events to be continuously processed in an existing process are solved.

Description

technical field [0001] The invention relates to the technical field of cloud platform event processing, in particular to a method for realizing a queue for processing declarative events. Background technique [0002] At present, the existing process for a cloud platform to realize the transfer of the current state of resources to the desired state is as follows: [0003] Step 1. Query to obtain the current state of the specified resource, and put it into the pending queue; Step 2, obtain the pending event from the queue, and compare the gap between the current state and the expected state; Step 3, process resource changes according to the gap; Fourth, if the processing is successful, the processing of the resource is ended; step five, if the processing fails, continue processing according to the state gap. [0004] There are following technical problems for above-mentioned existing flow process: [0005] 1. If there is already a status change event of a resource in the que...

Problems solved by technology

[0009] Based on the above problems, the present invention provides a method for implementing a queue for processing declarative events, which solves the problem of repeated processing, overload processing, and concurrency of normal events in failure events caused by the existing process returning the failure event to the queue as a normal event.
