[0001] The present invention relates to the field of data processing technology, and in particular to a window-based current limiting processing method, device, storage medium, electronic device and computer program product. Background Art

[0002] Take the risk query website for companies as an example. The server of this website does not have a high request volume at ordinary times. Assuming the request volume per second is 100, the maximum peak volume that the server can withstand is 500 requests per second. The requests at ordinary times only account for 20% of the maximum peak volume, which can fully meet the daily needs. But if a company goes bankrupt one day, it will cause a large number of users to flock to the risk query website in the same time period to query the company's risks. The request volume per second will exceed the extreme peak volume of 500, which may cause the server to crash.

[0003] To avoid this, such website servers often limit the maximum number of requests, and delay or discard requests that exceed the limit. However, such limiting methods are not flexible enough and cannot balance performance and accuracy. Summary of the invention

[0027] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0028] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0029] In addition, the terms "first" and "second" etc. are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0030] In actual application scenarios, within a certain period of time, when a large number of data requests are received that exceed the processing range that the server can bear, in order to avoid possible downtime, the interface from the front end to the back end is limited. This not only ensures that the server does not crash, but also ensures the availability of the server.

[0031] The embodiments of the present application provide a window-based current limiting processing method and device, an electronic device, and a computer-readable medium, which are described below in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1 , which shows a flow chart of a window-based current limiting processing method provided by some embodiments of the present application. As shown in the figure, the window-based current limiting processing method may include the following steps:

[0033] Step S101: Obtain at least two pre-set window current limiting modes, each window current limiting mode corresponds to at least a statistical time interval, a request amount limited within a statistical time interval, and a current limiting operation performed when the request amount exceeds the limit within the statistical time interval.

[0034] In an embodiment of the present application, at least two pre-set window current limiting modes include a first window current limiting mode that performs current limiting based on a rolling time window, and the statistical time interval corresponding to the first window current limiting mode is the first time interval.

[0035] Specifically, if the current window current limiting mode is the first window current limiting mode based on the rolling time window, the corresponding first time interval may be 10 seconds, and the corresponding request amount limited in the first time interval is 3000.

[0036] like Figure 2 As shown, it is a schematic diagram of a current limiting processing method based on a rolling time window in a specific application scenario provided according to an exemplary embodiment of the present application.

[0037] like Figure 2 As shown in the figure, the current limiting processing method based on the rolling time window is described as follows:

[0038] Through Figure 2The circle shown in the figure rolls on the time axis shown by the arrow. The rolling method is: only forward rolling is allowed, backward rolling is not allowed, and forward rolling can only be done once in each time period. Figure 2 The circle shown in the figure rotates once every 10 seconds. In response to each new request received, the current request count is increased by one. When the number of requests within 10 seconds is greater than 3000, the current limiting operation is started and the user requests subject to current limiting are forwarded to the corresponding static page. Figure 2 The circle shown ends the original scrolling and begins the next 10 seconds of scrolling.

[0039] In this example, each 10 seconds of scrolling corresponds to a statistical time interval of the window current limiting method. The number of requests limited to 3000 within 10 seconds corresponds to the number of requests limited by the window current limiting method in a statistical time interval. The operation of forwarding the limited user requests to the corresponding static page corresponds to the first current limiting operation performed when the request volume exceeds the limit.

[0040] In a possible implementation, if the current window current limiting mode is the first window current limiting mode based on the rolling time window, in order to achieve accurate statistics of the request volume, the current limiting processing method provided in the embodiment of the present application further includes the following steps:

[0041] When it is determined that the window current limiting mode is the first window current limiting mode, in response to the first statistical request, the request amount of the received requests is counted in real time, and the request amount is re-counted every first time interval.

[0042] In actual application scenarios, if the current window limiting mode is the first window limiting mode based on the rolling time window, when the rolling time is 10 seconds to 20 seconds, the request volume counted in 0-10 seconds will be cleared and the statistics will be restarted; this not only saves storage space, but also ensures the accuracy of the statistical request volume data.

[0043] In an embodiment of the present application, the at least two pre-set window current limiting methods also include a second window current limiting method based on a sliding time window, wherein the statistical time interval corresponding to the second window current limiting method is the second time interval, and the first time interval is greater than the second time interval.

[0044] Specifically, if the current window current limiting mode is the second window current limiting mode based on the sliding time window, the corresponding second time interval may be 1 second, and the request amount limited in the corresponding second time interval is 400.

[0045] like Figure 3As shown, it is a schematic diagram of a current limiting processing method based on a sliding time window in a specific application scenario provided according to an exemplary embodiment of the present application.

[0046] like Figure 3 As shown in the figure, the current limiting processing method based on the sliding time window is described as follows:

[0047] The maximum number of requests per second corresponding to the current limiting processing method based on the sliding time window is 400.

[0048] like Figure 3 In the current limiting processing method shown, the sliding window time can be set, for example, the sliding window time is set to 10 seconds; the minimum sliding time can also be set, for example, the minimum sliding time is 1 second.

[0049] Through Figure 3 When the sliding time window shown is used for current limiting, the first sliding time is 10 seconds, and the requests within 10 seconds are counted. When the counted requests are greater than 3000, the current limiting operation is performed, and the user requests whose current is limited are forwarded to the corresponding static page.

[0050] Assume that 400 requests are counted within 0-1 seconds. When sliding forward 1 second for the second time, 400 new requests can continue to be received between 10th and 11th seconds, and so on.

[0051] In this example, each forward slide of 1 second corresponds to a statistical time interval of the window current limiting method, and the number of requests limited to 400 within each forward slide of 1 second corresponds to the number of requests limited by the window current limiting method in a statistical time interval. The operation of forwarding the limited user requests to the corresponding static pages corresponds to the second current limiting operation performed when the request volume exceeds the limit.

[0052] In a possible implementation, if the current window current limiting mode is a second window current limiting mode based on a sliding time window, in order to achieve accurate statistics of the request volume, the current limiting processing method provided in the embodiment of the present application further includes the following steps:

[0053] When it is determined that the window limiting mode is the second window limiting mode, in response to the second statistical request, the request volume of the received requests is counted in real time, and the request volume is re-counted every second time interval; in this way, not only storage space can be saved, but also the accuracy of the statistical request volume data can be guaranteed.

[0054] Step S102: Apply one of the window current limiting modes to the received request.

[0055] In an embodiment of the present application, one of the window current limiting methods applied to the received request includes the first window current limiting method based on the rolling time window and the second window current limiting method based on the sliding time window. For a detailed description of the above two window current limiting methods, please refer to the description of the same or similar parts above, which will not be repeated here.

[0056] Step S103: When the current condition satisfies the switching condition for switching the window current limiting mode, a window current limiting mode switching operation is performed to apply another window current limiting mode to the received request.

[0057] In a possible implementation, when the current condition satisfies the switching condition for switching the window current limiting mode, performing the window current limiting mode switching operation includes the following steps:

[0058] Acquire a switching condition, where the switching condition includes a first switching condition for switching a current current limiting processing mode from a first window current limiting mode to a second window current limiting mode;

[0059] When the current window current limiting mode is the first window current limiting mode, determining whether the current condition satisfies the first switching condition;

[0060] In response to determining that the current conditions satisfy the first switching condition, the first window current limiting mode switching operation is executed to switch the currently applied window current limiting mode from the first window current limiting mode to the second window current limiting mode; in this way, when the current conditions satisfy the first switching condition, the currently applied window current limiting mode is automatically and intelligently switched from the first window current limiting mode to the second window current limiting mode.

[0061] In an embodiment of the present application, the first switching condition includes: the number of times the first current limiting operation is continuously performed under the current condition is greater than or equal to a third preset value.

[0062] In actual application scenarios, there is no specific limitation on the third preset value. The third preset value can be set to 2 times, 3 times, or 4 times.

[0063] In a possible implementation, before obtaining the switching condition, the current limiting method provided in the embodiment of the present application further includes the following steps:

[0064] configuring a first switching condition;

[0065] The first switching condition includes:

[0066] The number of times the first current limiting operation is continuously performed under the current condition is greater than or equal to a third preset value.

[0067] In actual application scenarios, there is no specific limitation on the third preset value. The third preset value can be set to 2 times, 3 times, or 4 times.

[0068] In a specific application scenario, when the first current limiting operation is performed twice in succession, if the first switching condition is met, the first window current limiting mode (current limiting mode based on a rolling window) is switched to the second window current limiting mode (current limiting mode based on a sliding window).

[0069] In a possible implementation, when the current condition satisfies the switching condition for switching the window current limiting mode, performing the window current limiting mode switching operation includes the following steps:

[0070] Acquire a switching condition, where the switching condition includes a second switching condition for switching the current current limiting processing mode from the second window current limiting mode to the first window current limiting mode;

[0071] When the current window current limiting mode is the second window current limiting mode, determining whether the current condition satisfies the second switching condition;

[0072] In response to determining that the current condition meets the second switching condition, the second window current limiting mode switching operation is performed; in this way, when the current condition meets the second switching condition, the currently applied window current limiting mode is automatically and intelligently switched from the second window current limiting mode to the first window current limiting mode.

[0073] In the embodiment of the present application, the second preset condition includes: the number of times the second current limiting operation is continuously performed under the current condition is less than or equal to a fourth preset value.

[0074] In actual application scenarios, there is no specific limitation on the fourth preset value. The fourth preset value can be set to 2 times, 3 times, or 4 times.

[0075] In a possible implementation, before obtaining the switching condition, the current limiting method provided in the embodiment of the present application further includes the following steps:

[0076] configuring a second switching condition;

[0077] The second switching condition includes:

[0078] The number of times the second current limiting operation is continuously performed under the current condition is less than or equal to a fourth preset value.

[0079] In actual application scenarios, there is no specific limitation on the third preset value. The third preset value can be set to 2 times, 3 times, or 4 times.

[0080] In a specific application scenario, when the second current limiting operation is not performed for three consecutive times and the second switching condition is met, the second window current limiting mode (current limiting mode based on sliding window) is switched to the first window current limiting mode (current limiting mode based on rolling window).

[0081] The first window current limiting method mentioned above corresponds to the rolling time window, and the second window current limiting method corresponds to the sliding time window method. For example, the current limiting process can be performed by converting the sliding time window to the rolling time window.

[0082] In the early stage, rolling time windows are used for flow control, and rolling time windows have higher performance. However, rolling time windows have disadvantages. For example, if the flow is limited to 1000 within 10 seconds, if the user request reaches 1000 within 1 second, then the server is in flow control for the remaining 9 seconds, and no request is missed, and the server is idle. Therefore, when the rolling time window meets the switching conditions (for example, 2 times in a row, the user request reached 1000 in the last 10 seconds, and the user request also reached 1000 in this 10 seconds). Switch to the sliding time window for more refined management.

[0083] The sliding time window can be set to a sliding time of 1 second, for example. Each time it slides forward by 1 second, the flow is limited to 400. If the number of requests during the 0th to 1st second exceeds 400, the number will be counted again from 0 to the 1st to 2nd second, and the flow will continue to be limited to 400, which can minimize the idle time of the server. If the number of requests does not exceed 400 for two consecutive times, the sliding time window will be switched back to the rolling time window.

[0084] The advantage of the rolling time window is that it has higher performance and faster request processing. Therefore, in daily situations where the above conditions are not met (current limiting operations are performed more than 2 times in a row), rolling time windows are used for current limiting. The advantage of the sliding time window is more refined management. During periods of large request volumes, you can switch to the sliding time window for more refined current limiting management, and switch back to the rolling time window after the request volume has leveled off. In this way, both performance and accuracy in the current limiting process can be taken into account.

[0085] In the above-mentioned embodiment, a window-based current limiting processing method is provided, and correspondingly, the present application also provides a window-based current limiting processing device. The window-based current limiting processing device provided in the embodiment of the present application can implement the above-mentioned window-based current limiting processing method, and the window-based current limiting processing device can be implemented by software, hardware, or a combination of software and hardware. For example, the window-based current limiting processing device can include integrated or separate functional modules or units to perform the corresponding steps in the above-mentioned methods.
