Description
Technical Field
The present invention relates to the field of data interaction technologies, and in particular, to a retry method and apparatus, a computer device, and a computer-readable storage medium.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
Data interaction and instruction transmission exist among different systems, and the ever-increasing business requirements enable the data interaction and instruction transmission among the different systems to be more frequent. However, regardless of the data interaction method, there is inevitably a situation in which the response is delayed. There are many reasons for the delay, such as network connection timeouts, system anomalies, etc. System response delays can cause inter-system data interaction failures.
For example, system a and system B agree to perform data interaction at 4 am each day by means of a text server. Due to network reasons, timeout occurs in the process of pushing the text to the system B by the system a, which results in failure of data interaction. For another example, according to the regulatory regulation, the system a and the system B agree that the system a remotely calls the instruction of the system B before 4 am every day to complete the reporting of the related data, and the remote call instruction fails due to the temporary abnormality of the service of the system B, so that the reporting of the data of the system a fails.
When response delay occurs, the partial system does not perform instruction retry operation any more. In addition, part of the system continuously executes retry operation of a designated number of times in a very short time; and the partial system performs instruction retry in equal time span and completes the instruction retry operation for specified times. However, the delay caused by network reasons or system service abnormality often requires manual intervention, and retry operations are continuously executed for a specified number of times in a short time, and the success rate is not high. In addition, if the time span is set to be longer or the total retry time of the instruction is longer under the condition of retrying the instruction in the equal time span, the data interaction is overtime; if the time span is set to be short, there may still be a case where data interaction fails after a specified number of retry operations are continuously performed, resulting in a low retry success rate. On the other hand, there is a problem that retry time span is not flexible enough when retry operations are continuously executed a specified number of times in a very short time or instruction retries are performed in a constant time span.
Therefore, the conventional retry method has a problem that the retry success rate and the retry time span are not flexible enough.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Fig. 1 shows a flow of implementing the retry method provided by the embodiment of the present invention, and for convenience of description, only the relevant parts related to the embodiment of the present invention are shown, and the detailed description is as follows:
as shown in fig. 1, a retry method includes:
102, executing the retry operation of the instruction with the prior sequence according to the retry time interval of the retry operation of the instruction with the prior sequence;
and 103, when the instruction retry operation in the front sequence fails, executing the instruction retry operation in the back sequence according to the retry time interval of the instruction retry operation in the back sequence until the end condition of the instruction retry operation is met.
The response delay is monitored and detected when the retry is performed, for example, the response delay of the monitored data interaction, and it will be understood by those skilled in the art that the response delay may also be other types of response delay, for example, the response delay of the remote invocation request, etc., which is not limited in particular by the embodiment of the present invention.
In the embodiment of the invention, when the corresponding delay is detected, the instruction retry operation is required to be carried out, and the retry time interval of the instruction retry operation is determined. Specifically, when the response delay is detected, the retry time interval of each instruction retry operation may be determined according to a preset retry base time interval and a retry weight parameter of each instruction retry operation.
The retry base time interval is a preset retry time interval, and can be preset according to actual conditions and specific requirements. For example, the retry base time interval is preset to be 1 second, or the retry base time interval is preset to be 3 seconds, and those skilled in the art will understand that the retry base time interval may also be preset to be 2 seconds, 2.5 seconds, and the like, which is not limited in particular by the embodiment of the present invention.
The retry weight parameter of each instruction retry operation is similar to the retry basic time interval, and the retry weight parameter configured in advance can be preset according to actual conditions and specific requirements. For example, the retry weight parameter is set to be an exponential parameter, or the retry weight parameter is set to be a logarithmic parameter, or the retry weight parameter is set to be a quadratic function that varies with time, and those skilled in the art can understand that the retry weight parameter may also be set to be a plurality of discrete constants that vary regularly, for example, the retry weight parameter of each instruction retry operation is a discrete constant that decreases sequentially, or a discrete constant that increases sequentially, or a discrete constant that decreases sequentially and then increases sequentially, or a discrete constant that increases sequentially and then decreases sequentially, and the like, and the embodiments of the present invention do not particularly limit this.
After determining the retry time interval of each instruction retry operation, the instruction retry operation in the previous order is executed according to the retry time interval of the instruction retry operation in the previous order. The retry operation of the instruction with the prior execution sequence may be executed successfully or failed. After the retry operation of the instruction whose execution sequence is prior succeeds, the retry operation may be ended.
However, after the instruction retry operation with the prior execution sequence fails, the instruction retry operation with the subsequent execution sequence needs to be further executed according to the retry time interval of the instruction retry operation with the subsequent execution sequence, and the above process is executed in a loop until the end condition of the instruction retry operation is satisfied. Wherein, satisfying the ending condition of the instruction retry operation comprises: (1) the execution of the retry operation of the instructions which follow the sequence is successful; (2) the retry number reaches a preset maximum retry number threshold.
The preset maximum retry number threshold is a preset maximum retry number threshold, and the preset maximum retry number threshold may be preset according to actual conditions and specific requirements. For example, the preset maximum retry number threshold is preset to be 5 times, or the preset maximum retry number threshold is preset to be 8 times, and it can be understood by those skilled in the art that the preset maximum retry number threshold can be preset to be 6 times, or 10 times, etc., and the embodiment of the present invention is not limited thereto.
In the embodiment of the invention, when the response delay is detected, the retry time interval of each instruction retry operation is determined according to the preset retry basic time interval and the retry weight parameter of each instruction retry operation; executing the instruction retry operation in the sequence according to the retry time interval of the instruction retry operation in the sequence; when the instruction retry operation before the sequence fails, the instruction retry operation after the sequence is executed according to the retry time interval of the instruction retry operation after the sequence until the end condition of the instruction retry operation is satisfied. The embodiment of the invention determines the retry time interval of each instruction retry operation according to the preset retry basic time interval and the retry weight parameter, thereby not only improving the flexibility of the retry time interval, but also improving the retry success rate.
In one embodiment of the present invention, in order to increase the retry success rate, the retry time interval of the sequentially previous instruction retry operation is sequentially increased to the retry time interval of the sequentially next instruction retry operation.
In determining the retry time interval of the instruction retry operation, it may be set that the retry time interval of each instruction retry operation exhibits a periodic variation. In the case of a retry failure, the time of the next retry interval may be appropriately extended in order to increase the success rate of the retry. Accordingly, the retry time interval of the instruction retry operation in the order before to the retry time interval of the instruction retry operation in the order after can be set to be gradually increased, thereby improving the success rate of the retry.
In an embodiment of the present invention, in order to further improve the retry success rate, the retry weight parameter of each instruction retry operation is an index parameter, and the retry time interval of each instruction retry operation satisfies the following relationship:
PN＝Q×KN-1N＝1,2,3…；
and K is greater than 1;
wherein, PNA retry time interval representing N instruction retry operations, Q representing a retry base time interval, KN-1A retry weight parameter indicating an nth instruction retry operation, N-1 indicating an exponent in the retry weight parameter, and K indicating a base in the retry weight parameter.
The embodiment of the invention can set the retry weight parameter of each instruction retry operation as the index parameter, and simultaneously satisfies that the base number of the index parameter is more than 1, so as to satisfy that the retry time interval of the instruction retry operation in the front sequence is gradually increased to the retry time interval of the instruction retry operation in the back sequence, thereby further improving the success rate of retry.
Specifically, for example, the base number K in the retry weight parameter is 2, the number of retries N is 5, and the retry base time interval is 2 seconds, and it can be determined that the retry time interval of the first instruction retry operation is 2 seconds, the retry time interval of the second instruction retry operation is 4 seconds, the retry time interval of the third instruction retry operation is 8 seconds, the retry time interval of the fourth instruction retry operation is 16 seconds, the retry time interval of the fifth instruction retry operation is 32 seconds, and the retry time intervals of the first to fifth instruction retry operations sequentially increase.
In one embodiment of the present invention, in order to improve the retry efficiency, the retry time interval of the retry operation of the instruction in the sequence before to the retry time interval of the retry operation of the instruction in the sequence after is decreased.
In determining the retry time interval of the instruction retry operation, it may be set that the retry time interval of each instruction retry operation exhibits a periodic variation. In the case of a retry failure, the time of the next retry interval may be appropriately reduced in order to improve the efficiency of the retry. Accordingly, the retry time interval of the instruction retry operation in the order before to the retry time interval of the instruction retry operation in the order after can be set to be decreased in sequence, thereby improving the retry efficiency.
In an embodiment of the present invention, in order to further improve the retry efficiency, the retry weight parameter of each retry operation is an index parameter, and the retry time interval of each retry operation satisfies the following relationship:
PN＝Q×KN-1N＝1,2,3…；
k is more than 0 and less than 1;
wherein, PNA retry time interval indicating an Nth instruction retry operation, Q indicating a retry base time interval, KN-1A retry weight parameter indicating an nth instruction retry operation, N-1 indicating an exponent in the retry weight parameter, and K indicating a base in the retry weight parameter.
The embodiment of the invention can set the retry weight parameter of each instruction retry operation as the index parameter, and simultaneously satisfies that the base number of the index parameter is more than 0 and less than 1, so as to satisfy that the retry time interval of the instruction retry operation in the front sequence is decreased to the retry time interval of the instruction retry operation in the back sequence, thereby further improving the retry efficiency.
Specifically, for example, the base number K in the retry weight parameter is 0.5, the number of retries N is 3, and the retry base time interval is 0.5 seconds, and it can be determined that the retry time interval of the first instruction retry operation is 0.5 seconds, the retry time interval of the second instruction retry operation is 0.25 seconds, the retry time interval of the third instruction retry operation is 0.125 seconds, and the retry time intervals of the first to third instruction retry operations are sequentially decremented, thereby improving the retry efficiency.
In an embodiment of the present invention, in order to improve the flexibility of the retry time interval, the retry time interval of the instruction retry operation in the previous order to the retry time interval of the instruction retry operation in the next order is sequentially decreased and then sequentially increased, or sequentially decreased and then sequentially increased.
In determining the retry time interval of the instruction retry operation, it may be set that the retry time interval of each instruction retry operation exhibits a periodic variation. At a certain stage or period, the time of the next retry interval may be reduced appropriately; the time for the next retry interval may be increased as appropriate during another phase or period. Accordingly, the retry time interval of the instruction retry operation in the previous order to the retry time interval of the instruction retry operation in the next order can be sequentially increased and then sequentially decreased, or sequentially decreased and then sequentially increased.
Fig. 2 shows a flow of implementing the retry method provided by the embodiment of the present invention, and for convenience of description, only the relevant parts of the embodiment of the present invention are shown, and the following details are described below:
in an embodiment of the present invention, as shown in fig. 2, in the retry method, in step 101, when a response delay is detected, a retry time interval of each instruction retry operation is determined according to a preset retry base time interval and a retry weight parameter of each instruction retry operation, and is replaced with:
in step 201, when a response delay is detected, a retry time interval of each instruction retry operation is determined according to a preset retry base time interval and a maximum retry number threshold.
In another embodiment, to further increase the flexibility of determining the retry time interval, when a response delay is detected, the retry time interval for each instruction retry operation is determined based only on the pre-configured retry base time interval and the maximum retry number threshold. The retry time interval of each instruction retry operation is based on a preset maximum retry threshold value and shows regular change. For example, the retry time interval of each instruction retry operation is sequentially increased or sequentially decreased, or the retry time interval is sequentially increased and then sequentially decreased, or the retry time interval is sequentially decreased and then sequentially increased.
In the embodiment of the invention, when the response delay is detected, the retry time interval of each instruction retry operation is determined according to the preset retry basic time interval and the maximum retry number threshold, so that the flexibility of determining the retry time interval can be further improved.
In one embodiment of the present invention, in order to improve the flexibility of the retry time interval, the retry time interval of each instruction retry operation satisfies the following relationship:
wherein, PNThe retry time interval of the Nth instruction retry operation is shown, Q is the retry base time interval, and M is the maximum retry threshold configured in advance.
In the embodiment of the invention, each retry time interval is executed to form a cosine function which takes the retry time as a variable on the basis of a preset maximum retry time threshold, and the change rule that the retry time interval of the instruction retry operation in the previous sequence to the retry time interval of the instruction retry operation in the next sequence is decreased in sequence and then increased in sequence or increased in sequence and then decreased in sequence is satisfied.
In an embodiment of the present invention, in order to improve flexibility of determining the retry time interval, on the basis of the above method steps, the retry method further includes:
configuring a retry basic time interval and a retry weight parameter of each instruction retry operation according to the received configuration instruction;
and configuring a preset maximum retry time threshold according to the received configuration instruction.
When the retry weight parameter of the configured retry base time interval and each instruction retry operation is preset with the maximum retry number threshold, the configuration instruction of a user (operation and maintenance personnel and the like) is received on a visual interface, or the configuration instruction is received in a clicking or inputting mode, and the preset maximum retry number threshold is further modified according to the received modification instruction, so that the flexibility of the configuration of the retry base time interval and the retry weight parameter of each instruction retry operation and the maximum retry number threshold is improved.
It is noted and described that any reasonable variation of the retry interval of the retry operation of the instruction described above by those skilled in the art is included in the scope of the present invention.

Since the principle of solving the problem of these apparatuses is similar to that of the retry method, the implementation of these apparatuses can be referred to the implementation of the method, and the repeated description is omitted.
