Delay message processing method and system

Abstract

The invention discloses a delay message processing method, which is executed in computing equipment and comprises the following steps of: receiving a delay message delivered by an application program,the message comprising an application identifier, a delay duration and a monitoring queue identifier; calculating to-be-triggered time of the delay message, storing the delay message and the to-be-triggered time in a data storage device in an associated manner, and inserting the delay message into a working time wheel or a buffer time wheel according to whether the to-be-triggered time is in a current preset period or a next preset period or not; taking out the delay message at the current moment from the working time round every other preset time, and sending the delay message to a to-be-consumed message queue, so that the application program performs monitoring processing; and when the current preset period time is over, the working time wheel and the buffer time wheel are exchanged, and a message of which the to-be-triggered time is in the next preset period is acquired from the data storage device and stored in the current buffer time wheel. The invention further discloses a corresponding system, computing equipment and a readable storage medium.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a delayed message processing method and system. Background technique [0002] With the rapid development of Internet services, many applications have derived the business requirement of automatically processing task B after a period of delay after the execution of pre-task A, that is, delayed tasks. This delayed task is initially completed by a timer, namely Every time the predecessor task A is executed, a timer is started, and after a certain period of time, task B is executed. However, due to the high concurrency of Internet applications, the opening, destruction, and scheduling of timers will occupy too much CPU during access peaks. resources, which have a great adverse effect on system stability.

[0002] With the rapid development of Internet services, many applications have derived the business requirement of automatically processing task B after a period of delay after the execution of pre-task A, that is, delayed tasks. This delayed task is initially completed by a timer, namely Every time the predecessor task A is executed, a timer is started, and after a certain period of time, task B is executed. However, due to the high concurrency of Internet applications, the opening, destruction, and scheduling of timers will occupy too much CPU during access peaks. resources, which have a great adverse effect on system stability

[0003] Subsequently, the processing of delayed messages through the message middleware was generated. A dead letter queue was established in the message middleware. The timer was simulated by setting the timeout time of the dead letter queue, and the corresponding target business queue was set. When a message is delivered After arriving in the dead letter queue, after the set timeout period, it will be automatically delivered to the set target business queue. Due to the variety of business forms, every time a new business requirement arises, a dead letter queue needs to be added to the middleware , and set the timeout time and target business queue for the dead letter queue. When the business requirements change, the related configuration of the message middleware also needs to be changed. In addition, the timeout time is configured in the queue dimension. In different occasions, the same business may have different If the delay time is long, a dead letter queue needs to be established for each delay time. There are a large number of redundant queues. At the same time, if the expiration time stipulated by the business is configurable, dynamic expansion cannot be achieved.
