[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Figure 1 This is a schematic diagram of the transaction processing system provided in the first embodiment of the present invention, as shown below. Figure 1 As shown, the transaction processing system provided in this embodiment of the invention includes a batch processing call terminal 1, an online call terminal 2, a rate limiting center 3, and a distributed service cluster 4, wherein:

[0031] The rate limiting center 3 is communicatively connected to the batch processing call terminal 1, the online call terminal 2, and the distributed service cluster 4. When processing batch transactions, the batch processing call terminal 1 sends a batch call request to the rate limiting center 3. When processing online transactions, the online call terminal 2 sends an online call request to the rate limiting center 3. The rate limiting center 3 executes the transaction processing method provided in this embodiment of the invention, distinguishes between online traffic and batch processing traffic, controls batch processing traffic, and improves the reliability of online transactions. The rate limiting center 3 distributes batch call requests and / or online call requests to the distributed service cluster 4 for processing.

[0032] Among them, batch processing call terminal 1 can be a server or a server cluster; online call terminal 2 can be a server or a server cluster; rate limiting center 3 includes but is not limited to a server; distributed service cluster 4 includes multiple servers.

[0033] The following describes the specific implementation process of the transaction processing method provided in this embodiment of the invention, taking the rate limiting center as the execution subject as an example.

[0034] Figure 2 This is a flowchart illustrating the transaction processing method provided in the second embodiment of the present invention, as shown below. Figure 2 As shown, the transaction processing method provided in this embodiment of the invention includes:

[0035] S201. Receive batch call requests sent by the batch processing client, each batch call request carrying a batch tag;

[0036] Specifically, each batch processing client can send a batch call request to the rate limiting center. Before sending the batch call request, a batch tag is set for each batch call request. The rate limiting center receives the batch call requests sent by the batch processing clients, and each batch call request carries a batch tag. After receiving each batch call request, the rate limiting center transmits the batch tag along the call chain of the batch processing transaction corresponding to the batch call request, thereby achieving full-link coloring of the batch processing transaction and identifying the batch processing traffic. The batch tag can be an encoding, string, etc., and can be set according to actual needs; this embodiment of the invention does not impose limitations.

[0037] S202. Count the number of batch call requests in the current time period based on the batch tags;

[0038] Specifically, the rate limiting center can count the number of received batch call requests. After the batch transaction corresponding to each batch call request is processed, it receives feedback information indicating that the batch call request processing is complete, thus enabling it to count the number of processed batch call requests. Based on the number of received batch call requests and the number of processed batch call requests, the rate limiting center can calculate the number of batch call requests in the current time period. Here, the current time period refers to the time period to which the current time belongs. Each time period is preset and set according to actual needs; this embodiment of the invention does not impose any limitations.

[0039] For example, if the rate limiting center counts the number of batch tags issued as 'a' and the number of batch tags revoked as 'b', then the number of batch call requests in the current time period is 'c' = 'ab'.

[0040] For example, a day's 24 hours can be divided into 24 equal periods, with each hour being one period.

[0041] S203. Based on the number of online service reserved providers and the total number of service providers in the current time period, obtain the batch processing call threshold for the current time period; wherein, the number of online service reserved providers in the current time period is obtained in advance;

[0042] Specifically, the rate limiting center obtains the batch processing call threshold for the current time period based on the total number of service providers and the number of online service reserved providers for the current time period. The total number of service providers can be the total number of servers in the distributed service cluster. The number of online service reserved providers for the current time period is pre-determined and can vary across different time periods. Typically, there are more online transactions during the day and more batch processing transactions at night. By dynamically adjusting the number of online service reserved providers for each time period, resources are fully utilized to process batch processing transactions while prioritizing online transactions, thus improving the reliability of transaction processing. The number of online service reserved providers for the current time period refers to the number of servers reserved for processing online services.

[0043] For example, the difference between the total number of service providers and the number of online service reserved providers in the current time period is used as the batch call threshold for the current time period.

[0044] S204. If it is determined that the number of batch calls in the current time period is greater than the batch call threshold in the current time period, a rate limiting instruction is sent to the batch call terminal so that the batch call terminal stops sending batch call requests.

[0045] Specifically, the rate limiting center compares the number of batch processing calls in the current time period with the batch processing call threshold for the current time period. If the number of batch processing calls in the current time period exceeds the batch processing call threshold, it indicates that there are no idle resources to process more batch processing services. To prevent batch call requests from failing, the rate limiting center sends a rate limiting instruction to the batch processing caller. After receiving the rate limiting instruction, the batch processing caller stops sending batch call requests to the rate limiting center, so that resources can be used to process the already sent batch call requests. The set time period is determined based on practical experience and is not limited in this embodiment of the invention.

[0046] The transaction processing method provided in this embodiment of the invention can receive batch call requests sent by a batch processing caller and set a batch tag for each batch call request; count the number of batch call requests in the current time period based on the batch tags; obtain the batch call threshold for the current time period based on the number of online service reserved providers and the total number of service providers in the current time period; if it is determined that the number of batch calls in the current time period is greater than the batch call threshold for the current time period, a rate limiting instruction is sent to the batch processing caller to cause the batch processing caller to stop sending batch call requests within a set time period. This can reduce the failure of batch call requests while ensuring online transactions, thereby improving the reliability of batch processing services. Furthermore, since the number of online service reserved providers and the batch call threshold can be dynamically adjusted in each time period, resources can be fully utilized for batch transaction processing while prioritizing online transactions, thus improving resource utilization.

[0047] Figure 3 This is a flowchart illustrating the transaction processing method provided in the third embodiment of the present invention, as shown below. Figure 3 As shown, based on the above embodiments, further, obtaining the number of online service reserved providers for the current time period includes:

[0048] S301. Obtain the online service call frequency corresponding to the current time period based on the number of online service calls in a preset number of historical time periods corresponding to the current time period;

[0049] Specifically, historical data on online service calls can be collected, and the number of connection service calls in each historical period can be statistically analyzed from this data. From the number of connection service calls in each historical period, the number of connection service calls in a preset number of historical periods corresponding to the current period can be obtained. Then, the average of the number of connection service calls in the preset number of historical periods corresponding to the current period can be calculated to obtain the online service call frequency for the current period. The historical periods corresponding to the current period are the same as the current period but different on the same date. The preset number is set according to actual needs, and this embodiment of the invention does not impose a limitation.

[0050] For example, a 24-hour day can be divided into 24 equal time slots, with each hour representing one time slot. The current time slot is 10:00-11:00, and the corresponding historical time slots are the periods from 10:00-11:00 prior to the date to which the current time slot belongs. The number of online service calls for the 15 historical time slots corresponding to the current time slot (10:00-12:00) can be obtained, and the average of these 15 historical time slots can be used as the online service call frequency for the current time slot.

[0051] S302. Obtain the average service time based on the time consumed by each online service within a preset historical time period;

[0052] Specifically, the system can obtain the successfully processed online services and the time consumed by each online service within a preset historical time period. By defining the successfully processed online services within the preset historical time period as the online services within that period, the system can obtain the time consumed by each online service within that period, and then calculate the total number of online services within that period. Finally, the system calculates the quotient of the sum of the time consumed by each online service within the preset historical time period and the total number of online services within that period to obtain the average service time. The preset historical time period can be set according to actual needs, and this embodiment of the invention does not impose any limitations.

[0053] S303. Based on the online service call frequency corresponding to the current time period, the average service consumption time, and the total number of service providers, obtain the number of online service reserved providers for the current time period.

[0054] Specifically, the rate limiting center obtains the number of online service reserved providers for the current time period based on the online service call frequency corresponding to the current time period, the average service consumption time, and the total number of service providers.

[0055] For example, it can be based on the formula Calculate the number of online service reserved providers for the current time period. ,in, This indicates the online service call frequency corresponding to the current time period. This indicates the average service time. This indicates rounding up to the nearest integer.

[0056] Figure 4 This is a flowchart illustrating the transaction processing method provided in the fourth embodiment of the present invention, as shown below. Figure 4 As shown, based on the above embodiments, the transaction processing method provided by the embodiments of the present invention further includes:

[0057] S401. Obtain the current length of the online queue based on the number of received online call requests and the number of processed online call requests;

[0058] Specifically, after receiving an online call request, the rate limiting center counts the number of received online call requests. Since batch call requests carry batch tags, while online call requests do not, the rate limiting center can distinguish between online call requests and batch call requests based on the batch tags. After the online transaction corresponding to the online call request is processed, the rate limiting center receives the processing completion result and counts the number of processed online call requests. The rate limiting center calculates the difference between the number of received online call requests and the number of processed online call requests, and uses this difference as the current length of the online queue.

[0059] S402. Based on the total number of service providers, the response time limit for online services, and the average service time, obtain the maximum length of the online queue; wherein, the average service time is obtained in advance;

[0060] Specifically, the rate limiting center can obtain the maximum length of the online queue based on the total number of service providers, the response time limit for online services, and the average service consumption time. The response time limit for online services refers to the timeframe within which an online service must provide a processing result; this time limit is preset and set according to actual needs, and is not limited in this embodiment of the invention. The average service consumption time is obtained in advance and can be calculated based on the consumption time of various online services within a preset historical time period.

[0061] For example, according to the formula Calculate the maximum length of the online queue. ,in, This indicates that there is a time limit for responding to online service requests. This represents the total number of service providers. This indicates the average service time.

[0062] S403. If it is determined that the ratio of the current length to the maximum length of the online queue is greater than the ratio of the number of online service reserved providers to the total number of service providers in the current time period, then reserve service resources for the online service and update the batch call threshold.

[0063] Specifically, the rate limiting center calculates the ratio of the current length of the online queue to the maximum length of the online queue. And calculate the ratio of the number of online service reserved providers to the total number of service providers. ,if Greater than This indicates a sudden increase in online call requests, necessitating the addition of reserved service resources. The rate limiting center will add reserved service resources for the online service and then update the batch call threshold based on these new resources. When adding reserved service resources for the online service, a set number can be added to the current number of reserved online service providers for the current time period to obtain the updated number of reserved online service providers for the current time period; alternatively, based on the scenario of a sudden increase in online call requests, a reasonable number can be added to the current number of reserved online service providers for the current time period to obtain the updated number of reserved online service providers for the current time period. The rate limiting center calculates the total number of service providers minus the updated number of reserved online service providers for the current time period to obtain the updated batch call threshold for the current time period, thus updating the batch call threshold for the current time period. Adding reserved service resources for the online service in the event of a sudden increase in online call requests further ensures the processing of online transactions and improves the reliability of online transaction processing. The set number is determined based on practical experience and is not limited in this embodiment of the invention.

[0064] For example, according to the formula Calculate the current length of the online queue. Maximum length of online queue ratio According to the formula Calculate the number of online service reserved providers for the current time period. Total number of service providers ratio .

[0065] Based on the above embodiments, the additional reserved service resources for online services further include:

[0066] The number of newly added online service reserved providers is determined based on the total number of service providers, the current length of the online queue, the maximum length of the online queue, and the number of online service reserved providers in the current time period.

[0067] Specifically, in scenarios involving a sudden increase in online call requests, the rate limiting center can determine the number of newly added online service reserved providers based on the total number of service providers, the current length of the online queue, the maximum length of the online queue, and the number of online service reserved providers in the current time period. This precise provision of the number of newly added online service reserved providers improves resource utilization in scenarios with a sudden increase in online call requests.

[0068] For example, it can be based on the formula Calculate the number of newly added online service reserved providers. ,in, Indicates the maximum length of the online queue. Indicates the current length of the online queue. This indicates the number of online service providers reserved for the current time period. Indicates the total number of service providers. This indicates rounding up. The updated number of online service reserved providers for the current time period is... The updated batch call threshold for the current time period is equal to Understandably, Less than or equal to .

[0069] Based on the above embodiments, the transaction processing method provided by the embodiments of the present invention further includes:

[0070] If it is determined that the ratio of the current length to the maximum length of the online queue is less than or equal to the ratio of the number of online service reserved providers to the total number of service providers in the current time period, then the reserved service resources newly added for the online service are released and the batch call threshold is restored.

[0071] Specifically, after the rate limiting center adds reserved service resources for the online service, if the sudden increase in online call requests disappears, the rate limiting center will release the newly added reserved service resources for the online service. The rate limiting center will then recalculate the ratio of the current length of the online queue to the maximum length of the online queue. The ratio of the number of online service reserved providers to the total number of service providers. ,if Less than or equal to This indicates that the sudden increase in online call requests has disappeared. The rate limiting center can then release the newly reserved service resources for online services and restore the batch call threshold. The rate limiting center subtracts the number of newly added online service reserved providers from the updated number of online service reserved providers for the current time period to release the newly added reserved service resources for online services. The rate limiting center then adds the number of newly added online service reserved providers to the updated batch call threshold for the current time period to restore the batch call threshold for the current time period.

[0072] Based on the above embodiments, the batch call request is further sent by the batch processing caller after triggering the batch call request and randomly going into sleep mode.

[0073] Specifically, due to the high concurrency of batch transactions, the batch processing client employs a random sleep mode after a batch call request is triggered. This random sleep mode means that the batch call request is not processed immediately after being triggered, but rather sleeps for t seconds (where t is randomly generated). After the sleep period, the batch call request is then sent to the rate limiting center. The triggering of the batch call request can be based on a set time or set conditions, and is configured according to actual needs; this embodiment of the invention does not impose any limitations. Randomly sleeping for a period before each batch call request reduces the concurrency of batch transactions, reduces rate limiting of the batch processing service due to short-term resource contention, and helps to lower the frequency of rate limiting for the batch processing service.

[0074] Based on the above embodiments, the transaction processing method provided by the embodiments of the present invention further includes:

[0075] The batch processing client receives the batch call request sent after receiving the rate limiting instruction information and waiting for a set time period.

[0076] Specifically, after receiving the rate limiting instruction, the batch processing client stops sending batch call requests to the rate limiting center for a set time period to ensure that resources are available to process the already sent batch call requests. After the set time period, the batch processing client will send batch call requests to the rate limiting center to continue processing batch transactions.

[0077] Based on the above embodiments, the transaction processing method provided by the embodiments of the present invention further includes:

[0078] If it is determined that the number of batch calls in the current time period is less than the batch call threshold for the current time period, then a rate limiting release instruction is sent to the batch caller.

[0079] Specifically, after sending the rate limiting instruction to the batch processing client, the rate limiting center recalculates the number of batch processing calls for the current time period. If the recalculated number of batch processing calls for the current time period is less than the batch processing call threshold for that period, it can send a rate limiting release instruction to the batch processing client. Upon receiving the rate limiting release instruction, the batch processing client sends a batch call request to the rate limiting center to initiate batch transaction processing in a timely manner.

[0080] Figure 5 This is a schematic diagram of the transaction processing device provided in the fifth embodiment of the present invention, as shown below. Figure 5 As shown, the transaction processing apparatus provided in this embodiment of the invention includes a receiving module 501, a statistics module 502, an obtaining module 503, and a sending module 504, wherein:

[0081] The receiving module 501 is used to receive batch call requests sent by the batch processing caller, each batch call request carrying a batch tag; the statistics module 502 is used to count the number of batch call requests in the current time period based on the batch tag; the obtaining module 503 is used to obtain the batch call threshold for the current time period based on the number of online service reserved providers and the total number of service providers in the current time period; wherein, the number of online service reserved providers in the current time period is obtained in advance; the sending module 504 is used to send rate limiting indication information to the batch processing caller after determining that the number of batch calls in the current time period is greater than the batch call threshold for the current time period, so that the batch processing caller stops sending batch call requests.

[0082] Specifically, each batch processing client can send a batch call request to the receiving module 501. Before sending the batch call request, a batch tag is set for the batch call request. The receiving module 501 receives the batch call requests sent by the batch processing clients, each batch call request carrying a batch tag. After receiving each batch call request, the batch tag is transmitted along the call chain of the batch processing transaction corresponding to the batch call request, thereby achieving full-link coloring of the batch processing transaction and identifying the batch processing traffic. The batch tag can be an encoding, string, etc., and can be set according to actual needs; this embodiment of the invention does not impose limitations.

[0083] The statistics module 502 can count the number of received batch call requests. After the batch transaction corresponding to each batch call request is processed, feedback information indicating that the batch call request processing is complete will be received, thus enabling the counting of the number of processed batch call requests. Based on the number of received batch call requests and the number of processed batch call requests, the statistics module 502 can calculate the number of batch call requests in the current time period. Here, the current time period refers to the time period to which the current time belongs. Each time period is preset and set according to actual needs; this embodiment of the invention does not impose any limitations.

[0084] The obtaining module 503 obtains the batch processing call threshold for the current time period based on the total number of service providers and the number of online service reserved providers for the current time period. The total number of service providers can be the total number of servers in the distributed service cluster. The number of online service reserved providers for the current time period is pre-obtained and can vary across different time periods. Typically, there are more online transactions during the day and more batch processing transactions at night. By dynamically adjusting the number of online service reserved providers for each time period, while prioritizing online transactions, resources are fully utilized to process batch processing transactions, improving the reliability of transaction processing. The number of online service reserved providers for the current time period refers to the number of servers reserved for processing online services.

[0085] The sending module 504 compares the number of batch processing calls in the current time period with the batch processing call threshold for the current time period. If the number of batch processing calls in the current time period is greater than the batch processing call threshold, it indicates that there are no idle resources to process more batch processing services. To avoid batch call requests failing, the sending module 504 sends a rate limiting instruction to the batch processing caller. After receiving the rate limiting instruction, the batch processing caller stops sending batch call requests to the rate limiting center, so that resources are available to process the already sent batch call requests. The set time period is determined based on practical experience and is not limited in this embodiment of the invention.

[0086] The transaction processing apparatus provided in this embodiment of the invention can receive batch call requests sent by a batch processing caller and set a batch tag for each batch call request; count the number of batch call requests in the current time period based on the batch tags; obtain the batch call threshold for the current time period based on the number of online service reserved providers and the total number of service providers in the current time period; if it is determined that the number of batch calls in the current time period is greater than the batch call threshold for the current time period, a rate limiting instruction is sent to the batch processing caller to cause the batch processing caller to stop sending batch call requests within a set time period. This can reduce the failure of batch call requests while ensuring online transactions, thereby improving the reliability of batch processing services. Furthermore, since the number of online service reserved providers and the batch call threshold can be dynamically adjusted in each time period, resources can be fully utilized for batch transaction processing while prioritizing online transactions, thus improving resource utilization.
