In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the steps. For example, some steps may be decomposed, and some steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
In the related art, a scheme for processing a data acquisition request based on an LRU cache mechanism has appeared. In general, after receiving a current data acquisition request sent by a data request device, a data cache device may determine whether response data corresponding to the current data acquisition request exists in the data cache device, and if so, send the response data corresponding to the current data acquisition request to the data request device; if the current data acquisition request does not exist, acquiring response data corresponding to the current data acquisition request from the database service equipment, and sending the response data to the data request equipment; and storing the response data in the data cache device, and after receiving the data acquisition request which is the same as the current data acquisition request again, directly acquiring the corresponding response data from the data cache device and sending the response data to the data request device. In order to save the cache space, the data cache device may replace the data in the cache space with an LRU cache mechanism.
However, the principle of the LRU cache mechanism is that when the cache space is close to saturation, the response data which is requested in the recent time with the lowest frequency is deleted, and thus, the LRU cache mechanism can always store the response data which is frequently requested in the cache space into the cache space; and if the data volume of the response data in the cache space is always in an unsaturated state, the LRU cache mechanism can also keep the response data in the cache space all the time. Under these circumstances, if the response data corresponding to a certain data acquisition request in the database service device has been updated, and the data cache device receives the data acquisition request, the response data returned to the data request device is still old response data, which results in inconsistency between the response data acquired by the data request device and the actual response data.
In view of the foregoing, exemplary embodiments of the present disclosure provide a request processing method, which is directed to a service scenario for processing a data acquisition request based on an LRU cache mechanism. The application scenarios of the request processing method include but are not limited to: in the process of acquiring data by a user terminal, after the data cache equipment receives a current data acquisition request sent by the user terminal, if the cache space of the data cache equipment is determined to store response data corresponding to a data identifier in the current data acquisition request, whether the response data corresponding to the data identifier in the current data acquisition request is overdue can be judged, and if the response data corresponding to the data identifier in the current data acquisition request is determined to be unexpired, the response data corresponding to the data acquisition request can be sent to the user terminal; if the response data corresponding to the data identifier in the current data acquisition request is determined to be expired, the response data corresponding to the current data acquisition request can be acquired again from the database service equipment, and the acquired response data is sent to the user terminal, meanwhile, an expiration time can be set for the acquired response data again, so that after the data acquisition request which is the same as the data identifier in the current data acquisition request is received next time, the acquired response data can be determined to be directly sent to the data request equipment, or the response data corresponding to the data identifier is acquired and updated. The method and the device can ensure that the response data acquired by the user terminal at the current moment is consistent with the response data in the database service equipment, and improve the accuracy of the response data acquired by the user terminal.
In order to implement the request processing method described above, exemplary embodiments of the present disclosure provide a request processing system.

The data caching device may process a data obtaining request sent by the data requesting device based on the LRU cache mechanism and the data response expiration mechanism, and specifically, the data caching device 120 may receive a current data obtaining request sent by the data requesting device 110, where the current data obtaining request includes a data identifier and a request time; the data caching device 120 may search for target response data in a response data set maintained in the data caching device 120 according to the data identifier, and if the response data set includes the target response data, determine an expiration time of the target response data, where the target response data is response data corresponding to the data identifier; determining whether the target response data is expired or not according to the request time and the expiration time of the target response data; if the targeted response data is not expired, the targeted response data may be sent to the data requesting device 110. If the target response data is expired, the updated target response data can be acquired from the database service equipment 130; the updated target response data is sent to the data request device 110, and meanwhile, the data cache device 120 may set an expiration time for the updated response data, so that after receiving a data acquisition request with the same data identifier as that in the current data acquisition request next time, it may be determined to send the updated response data directly to the data request device, or update the response data corresponding to the data identifier again. The number of the response data in the response data set maintained by the data caching device can be determined based on the size of the caching space, which is not limited in the embodiment of the disclosure, so that the response data acquired by the data requesting device is ensured to be the latest response data, and the accuracy of the response data returned by the data requesting device is improved.

The following describes a request processing method from the perspective of a data caching device. Fig. 2 shows an exemplary flow of a request processing method performed by a server, which may include:
step S201, a current data acquisition request sent by the data request device is received.
Step S202, if the response data set comprises the target response data, determining the expiration time of the target response data.
Step S203, determining whether the target response data is expired according to the request time and the expiration time of the target response data.
And step S204, if the target response data is not expired, sending the target response data to the data request equipment.
In this disclosure, the data requesting device may send a current data obtaining request to the data caching device, where the current data obtaining request may include a data identifier and a request time, so that the data caching device may determine, in the data caching device, target response data that needs to be obtained by the current data obtaining request according to the data identifier. The target response data is response data corresponding to the data identifier in the current data acquisition request in a response data set maintained by the data caching device.
It should be noted that the response data set includes at least one data identifier and a data identifier corresponding to each response data, and a correspondence between the response data in the response data set and the data identifier is determined by the data caching device according to the data identifier in the historical data acquisition request and the response data acquired from the database service device according to the data identifier in the historical data acquisition request, where due to a limitation of a cache space in the data caching device, the response data set may be maintained based on an LRU cache mechanism, and the historical data acquisition request may be a data acquisition request received by the data caching device at any time before the data acquisition request is received.
Meanwhile, after the data caching device acquires the response data corresponding to the data identifier in the historical data acquisition request from the database service device, the expiration time of the response data needs to be determined, so that after the data caching device receives the current data acquisition request and determines that the response data set comprises the target response data, the data caching device can send the target response data to the data request device by using the request time and the expiration time of the target response data under the condition that the target response data is determined not to be expired, the data request device finally acquires the latest response data, and the accuracy of the response data acquired by the data request device is improved.
To sum up, according to the request processing method provided by the embodiment of the present disclosure, after the current data acquisition request is received, after the response data set includes the target response data that needs to be acquired by the current data acquisition request, it is required to determine whether the target response data is expired according to the request time and the expiration time of the target response data, and when it is determined that the target response data is not expired, the target response data may be sent to the data request device, so as to ensure that the response data finally acquired in the data request device is the latest response data corresponding to the current time, and improve the accuracy of the response data acquired by the data request device.
In an optional embodiment, in step S201, the data caching device may receive a current data obtaining request sent by the data requesting device.
In this disclosure, a data requesting device may send a current data obtaining request to a data caching device, where the current data obtaining request may include a data identifier, and a request time when the data requesting device generates the current data obtaining request.
In an optional implementation manner, the data caching device may receive a current data obtaining request sent by the data requesting device, and at the same time, may parse the current data obtaining request to obtain a data identifier and a request time in the current data obtaining request.
In an optional embodiment, in step S202, if the data caching device determines that the response data set includes the target response data, the expiration time of the target response data is determined.
In the embodiment of the present disclosure, the data cache device may maintain the response data set, and the correspondence between the data identifier in the response data set and the response data is determined by the data cache device according to the received historical data acquisition request, and meanwhile, the data cache device may maintain the response data set based on an LRU cache mechanism.
The process of determining the corresponding relationship between the data identifier in the response data set and the response data by the data caching device according to the received historical data acquisition request may include: after the data cache device receives the historical data acquisition request, the historical data acquisition request can be analyzed to obtain a data identifier and a request time in the historical data acquisition request, if the response data set does not include response data corresponding to the data identifier, the response data corresponding to the data identifier can be acquired from the database service device according to the data identifier, and the data identifier and the response data corresponding to the data identifier are added into the response data set.
Further, after determining the response data in the response data set according to the received historical data acquisition request, the data caching device needs to determine the expiration time of the response data, so that after receiving the current data acquisition request which is the same as the historical data acquisition request, the data caching device determines whether the target response data is expired according to the request time in the current data acquisition request and the expiration time of the target response data, and when determining that the target response data is not expired, the data caching device can send the target response data to the data requesting device, thereby ensuring that the data requesting device acquires the latest response data corresponding to the current data acquisition request, and improving the accuracy of the response data acquired by the data requesting device. The current data acquisition request identical to the historical data acquisition request refers to the current data acquisition request with the data identifier identical to the data identifier in the historical data request
The process of determining the expiration time of the response data by the data caching device may include: after acquiring the response data corresponding to the data identifier in the historical data acquisition request from the database service device, the data caching device may determine an expiration time of the response data based on a preconfigured data retention time and an acquisition time of the response data, where the determining the expiration time of the response data based on the preconfigured data retention time and the acquisition time of the response data may include: and delaying the acquisition time of the response data by the preset data retention time to determine the acquisition time as the expiration time of the response data. The preconfigured data retention time may be determined based on an actual service scenario, which is not limited in the embodiment of the present disclosure.
For example, assuming that the preset data retention time is 3 minutes, and the data caching device obtains the response data corresponding to the data identifier a1 from the database service device at 14 points 25 points 14 at 6 months and 5 days at 2021, the expiration time of the response data corresponding to the data identifier a1 may be determined to be 28 points 14 at 6 months and 5 days at 2021.
In an alternative embodiment, the process of the data caching device determining whether the target response data is included in the response data set may include: the data cache device may compare the data identifier in the current data acquisition request with each data identifier in the response data set, and if the response data set includes a data identifier that is the same as the data identifier in the current data acquisition request, it may be determined that the response data set includes the target response data; if the reply data set does not include the data identifier that is the same as the data identifier in the current data acquisition request, it may be determined that the reply data set does not include the target reply data.
In an optional implementation manner, when the data caching device adds the response data in the response data set, the response data may also carry an expiration time of the response data, and the process of the data caching device determining the expiration time of the target response data may include: when a certain to-be-deleted response data in the response data set needs to be deleted, the response data to be deleted and the data identifier of the to-be-deleted response data and the expiration time are deleted simultaneously, so that no redundant data exists in the response data set.
In an optional implementation manner, an expiration time data set may be further maintained in the data caching device, where the expiration time data set includes an expiration time and a data identifier of each piece of response data in the response data set, and the process of the data caching device determining the expiration time of the target response data may include: and acquiring the expiration time of the target response data in the expiration time data set.
The process of acquiring the expiration time of the target response data in the expiration time dataset may include: and searching the expiration time of the response data corresponding to the data identifier which is the same as the data identifier in the current data acquisition request in the expiration time data set by using the data identifier in the current data acquisition request to obtain the expiration time of the target response data. The response data and the expiration time of the response data can be respectively stored in different data sets without modifying codes capable of realizing an LRU cache mechanism, the workload of developers in the configuration process of the data cache equipment can be reduced,
in an optional embodiment, in step S203, the data caching device may determine whether the target response data is expired according to the request time and the expiration time of the target response data.
In an alternative embodiment, the process of determining, by the data caching device, whether the target response data is expired according to the request time and the expiration time of the target response data may include: comparing the request time in the current data acquisition request with the expiration time of the target response data, and if the request time is less than or equal to the expiration time of the target response data, determining that the target response data is not expired; and if the request time is greater than the expiration time of the target response data, determining that the target response data is expired.
For example, assuming that the data identifier in the current data acquisition request is a1, the request time is 14: 26: 6/5/2021, and after the data caching device receives the current data acquisition request, if it is determined that the response data set includes the response data a1 corresponding to the data identifier a1, it may be determined that the response data set includes the target response data a1, and the expiration time for acquiring the target response data a1 is 28: 6/5/2021, and since the request time 26: 6/5/28: 2021 is smaller than the expiration time 28: 6/5/2021 of the target response data a1, it may be determined that the target response data a1 in the data caching device is not expired.
In an optional embodiment, in step S204, if the data caching device determines that the target response data is not expired, the target response data may be sent to the data requesting device.
In an optional embodiment, if the data caching device determines that the target response data is out of date, the updated target response data may be acquired from the database service device; and sending the updated target response data to the data request equipment to ensure that the data request equipment acquires the latest response data and improve the accuracy of the response data acquired by the data acquisition request.
The process of acquiring, by the data caching device, the updated target response data from the database service device may include: generating a response data acquisition request according to the data identification in the current data acquisition request, sending the response data acquisition request to the database service equipment, receiving response data which is sent by the database service equipment and corresponds to the data identification, and obtaining updated target response data; the response data acquisition request includes a data identifier in the current data acquisition request, and the database service device may determine, according to the data identifier, response data corresponding to the data identifier in the database service device.
It can be understood that, in the embodiment of the present disclosure, after the data caching device acquires the updated target response data from the database service device, the target response data in the response data set needs to be updated to the updated target response data, and the expiration time of the updated target response data is determined according to the acquisition time of the updated target response data and the pre-configured data retention time, so as to ensure that the data caching device can return the latest target response data to the data request device after receiving the same data acquisition request as the current data acquisition request again, and ensure the accuracy of the response data acquired by the data request device. The process of updating the target response data in the response data set to the updated target response data may include: and replacing the target response data in the response data set by the updated target response data. The data acquisition request identical to the current data acquisition request refers to a data acquisition request with the same data identifier as the current data acquisition request.
In an optional implementation manner, when the target response data in the response data set is updated to the updated target response data, the data caching device may further update the expiration time of the updated target response data in the response data set, so that in the process that the LRU cache mechanism maintains the response data set, when a certain response data to be deleted in the response data set needs to be deleted, the response data to be deleted, the data identifier of the response data to be deleted, and the expiration time may be deleted at the same time, so that there is no redundant data in the response data set.
In an optional implementation manner, after determining the expiration time of the updated target response data, the data caching device may further replace the expiration time of the target response data in the expiration time data set with the expiration time of the updated target data.
The process of replacing the expiration time of the target response data in the expiration time data set with the expiration time of the updated target data may include: and determining the expiration time of the response data corresponding to the data identifier by using the data identifier in the current data acquisition request to obtain the expiration time of the target response data, and replacing the expiration time of the target response data with the updated expiration time of the target response data.
In an optional embodiment, if the data caching device determines that the response data set does not include the target response data, the target response data is obtained from the database service device, and the target response data is sent to the data requesting device.
It can be understood that, after the data caching device acquires the target response data from the database service device, the data identifier and the target response data are further added to the response data set, and the expiration time of the target response data is determined according to the acquisition time of the target response data and the preconfigured data retention time. After the data caching device acquires the data acquisition request which is the same as the current data acquisition request again, the latest target response data can be returned to the data request device, and the accuracy of the response data acquired by the data request device is ensured.
In an optional implementation manner, when the data identifier and the target response data are added to the response data set, the data caching device may further add the expiration time of the target response data to the response data set, so that in the process of maintaining the response data set by the LRU cache mechanism, when a certain to-be-deleted response data in the response data set needs to be deleted, the to-be-deleted response data, the data identifier and the expiration time of the to-be-deleted response data may be deleted at the same time, and no redundant data exists in the response data set.
In an optional implementation manner, after determining the expiration time of the target response data, the data caching device may further add the expiration time of the target response data to the expiration time data set, where adding the expiration time of the target response data to the expiration time data set may include: and adding the data identifier in the current data acquisition request and the corresponding relation of the expiration time of the target response data into an expiration time data set.
In an optional implementation manner, since the response data set is maintained based on the LRU cache mechanism, if the response data set does not include the target response data, there may be a case that the response data corresponding to the data identifier is deleted, if the data caching device stores the expiration time of the response data in the response data set through the expiration time data set, before obtaining the target response data from the database service device, the data caching device may further determine whether the expiration time of the deleted target data is included in the expiration time data set, and if the expiration time of the deleted target response data is included in the expiration time data set, delete the expiration time of the deleted target response data. The corresponding relations between the response data set and the expiration data set, the response data corresponding to the data identification and the expiration of the response data are kept consistent, and redundant data in the expiration data set are prevented.
The process of determining whether the past due time data set contains the past due time of the deleted target data may include: and determining whether a data identifier which is the same as the data identifier in the current data request exists in the data set at the expiration time or not according to the data identifier in the current data request, if so, determining the expiration time of the deleted target response data contained in the data set at the expiration time, and if not, determining the expiration time of the deleted target response data not contained in the data set at the expiration time.
In an optional implementation manner, as shown in fig. 3, after the data cache receives the current data obtaining request sent by the data requesting device, the process of returning the request result to the data requesting device may include:
step S301, analyzing the current data acquisition request to obtain a data identifier and a request time;
step S302, judging whether target response data exist in the response data set according to the data identification;
step S303, if the target response data exist in the response data set, determining whether the target response data are overdue according to the overdue time and the request time of the target response data;
step S304, if the target response data is not overdue, sending the target response data to the data request equipment;
step S305, if the target response data is overdue, acquiring updated target response data from the database service equipment, and sending the updated target response data to the data request equipment;
in this step 305, after acquiring the updated target response data from the database service device, the target response data in the response data set is updated to the updated target response data, and the expiration time of the updated target response data is determined according to the acquisition time of the updated target response data and the pre-configured data retention time, and the expiration time of the updated target response data is determined according to the expiration time of the target response data in the expiration time data set.
Step S306, if the response data set does not have the target response data, acquiring the target response data from the database service equipment, and sending the target response data to the data request equipment;
in step 306, after the target response data is acquired from the database service device, the data identifier and the target response data are further added to the response data set, the expiration time of the target response data is determined according to the acquisition time of the target response data and the pre-configured data retention time, and the expiration time of the data identifier and the target response data is stored and the expiration time data set.
For example, it is assumed that the answering data set of the data caching device includes three answering data, which are answering data a1 corresponding to data identifier a1, answering data a2 corresponding to data identifier a2, and answering data A3 corresponding to data identifier A3, and the expiration times of the answering data are stored in the expiration time data set, the expiration times of the three answering data included in the expiration time data set are the expiration times 2021 year 7 month 5 day 13 point 26 of the answering data a1 corresponding to data identifier a1, the expiration time 2021 year 7 month 5 day 13 point 30 of the answering data a2 corresponding to data identifier a2, and the expiration time 2021 year 7 month 5 day 13 point 10 of the answering data A3 corresponding to data identifier A3, and meanwhile, in the current service scenario, the preconfigured data is reserved for 5 minutes.
