The implementation mode of the architecture is mainly that the gateway calls the micro-services and calls the micro-services mutually. Actually, each interface provided by each micro service has an upper limit of the number of requests or an upper limit of resources, and when the micro service request reaches the upper limit, or when other special conditions, such as abnormal conditions of machine resources or network jitter, occur, there will be a request congestion of the micro service. Once the congestion occurs, other requests continue to be congested, so that the whole micro-service system is unavailable. Or a higher-level system, when the situation occurs, the queue is used for storing the task message, the queue is a first-in first-out queue, the first-in message is processed firstly, so that a lot of time is consumed when the message which arrives at the next time is processed, and the timeout is abandoned, so that the request fails.

According to the description, under the condition of insufficient resources, the latest received task message is processed preferentially, the processing success rate of the latest task message is ensured, and therefore the overall request success rate is improved.
The invention also proposes a computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps as described above.
Example one
Referring to fig. 2, a first embodiment of the present invention is: a request processing optimization method can be applied to a micro-service architecture, and comprises the following steps:
s1: creating a first-in first-out queue and a first-in last-out queue; that is, in the system content of the server, two queues are created, i.e., a first-in first-out queue and a first-in last-out queue. The length of the queue can be set according to conditions such as the size of a memory, and preferably, the length of the queue is 1024.
S2: according to a preset period, detecting the CPU occupancy rate of equipment where a server side is located, or acquiring the total number of task messages processed in the period, and calculating to obtain the message processing speed. Detecting the occupation condition of CPU resources in each period to obtain the CPU occupancy rate of the current period; or when the current period is finished, counting the total number of the task messages processed by the server in the current period, and dividing the total number by the duration of the current period to obtain the message processing speed of the current period.
For example, the CPU occupancy is detected every 10s, or the total number of task messages processed by the service end in the 10s is counted every 10s, and then is divided by 10, so as to obtain the message processing speed corresponding to the 10 s.
Further, the CPU occupancy rate or the message processing speed is stored in a local cache. Preferably, only the latest CPU occupancy or message processing speed may be stored in the local cache, so as to save the storage space of the local cache.
S3: receiving a task message sent by a request end; the request end may be a client or a server.
S4: and judging whether the request processing of the server is normally executed, namely whether the request timeout condition does not occur in the server and the upper limit of the task processing quantity is not reached, if so, processing the received task message according to the existing processing method, otherwise, whether the request timeout condition occurs in the server or the task processing quantity is on-line is reached, and if not, writing the received task message into a queue, and executing the step S5.
S5: acquiring the CPU occupancy rate or the message processing speed of the previous period; namely, the newly detected CPU occupancy or the newly calculated message processing speed is acquired.
S6: and judging whether the CPU occupancy rate does not reach a preset first threshold value or whether the message processing speed reaches a preset second threshold value, if so, namely the resource occupancy rate is lower or the message processing speed is higher, indicating that the task message can be continuously received and processed, executing the step S7, and if not, namely the resource occupancy rate is higher or the message processing speed is lower, indicating that more task messages cannot be continuously processed, executing the step S8.
Preferably, the first threshold is 60%; the second threshold is dependent on the specific traffic operation.
S7: the write-in thread writes the received task message into the first-in first-out queue, and the consumption thread takes out the earliest written task message from the first-in first-out queue for processing; the first-in first-out queue is adopted to store the task messages, and the first-in task messages are processed preferentially.
S8: the write-in thread writes the received task message into the first-in-first-out queue, and the consumption thread takes out the latest written task message from the first-in-first-out queue for processing; namely, the first-in and second-out queues are adopted to store the task messages, and the task messages which arrive after the priority processing are also adopted.
When the CPU occupancy is large or the processing speed is slow, if the task message that arrives first is processed first, the task processing is slow, and it is easy for the processing time of the task that is overtime to be delayed (or for the request end to be determined to be failed due to the overtime of the request), which may cause the request to fail, and the task message that arrives later may be abandoned due to the overtime, which may cause the request to fail. Therefore, under the scene, the latest received task message is processed preferentially, and the earlier task message is processed, so that the processing success rate of the later-achieved task message is ensured, and the overall request success rate is improved.
Further, if the processing speed of the message does not reach the speed of writing the message into the queue, the number of the task messages in the queue is increased, and when the maximum supported number of the queue is reached, the queue can not support more messages to be stored, and the task messages written into the queue earlier are discarded or refused to be processed.
Further, for steps S5-S8, if it is detected in the current cycle that the CPU occupancy of the previous cycle reaches the first threshold or the message processing speed does not reach the second threshold, the write thread immediately writes the task message into the fifo queue, but the consumption thread continues to process the task message in the fifo queue in the current cycle, and no matter whether the consumption thread can consume the task message in the fifo queue in the current cycle, the consumption thread starts to process the task message in the fifo queue in the next cycle, and the task message in the fifo queue is abandoned, that is, the default request fails. This is because the alert threshold has been reached at this time, and priority needs to be given to successful processing of the latest task message.
In this embodiment, a new self-adjusting function is adopted, and when a request timeout condition occurs at a server or the upper limit of the task processing number is reached, two queues are used to store task messages, one is a first-in first-out queue, and the other is a first-in last-out queue, and the task messages are specifically analyzed and processed according to the resource occupation condition (mainly CPU occupancy rate) or the message processing speed of the device where the server is located. When the CPU occupancy rate is low or the message processing speed is high, the task message can be continuously received and processed, the first-in first-out queue is adopted to store the task message and perform subsequent processing, and the subsequent task can be quickly consumed and completed due to sufficient resources. When the CPU occupancy rate is high or the message processing speed is low, which indicates that more tasks cannot be processed continuously, the first-in and second-out queues are adopted to store the task messages, so that the latest task messages can be processed quickly, the success rate is ensured, and the previously received task messages have high request failure probability and are subsequently processed. By adopting the mode of processing the tasks in a self-adjusting way, the probability of task execution failure caused by insufficient resources can be reduced to a great extent, and the execution success rate is improved.
