When a user uses an application program, the user needs to continuously obtain corresponding display data from a data storage medium of the application program according to a requirement, for example, when the user needs to obtain road condition display information, the user needs to send a road condition display information obtaining request to the application program, and at this time, the application program obtains corresponding map data, vehicle data and the like from a database of the application program according to the request. However, if data is obtained from the database for each data request, the number of database interactions is increased, which affects the stability of the database.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for displaying cache data according to an embodiment of the present application, where as shown in fig. 1, the method includes:
s1, receiving a data acquisition request sent by the client, wherein the data acquisition request comprises a request time.
The server corresponding to the application program receives data acquisition requests generated by the operation of the user at the client, and generally, the data acquisition requests at least include request time, that is, time when the data acquisition requests are generated, and may also include specific request content, user information, device information, and the like of the data acquisition requests.
And S2, calculating the difference between the request time and the time when the client sends the data acquisition request for the first time to obtain the request time interval.
As known from the background art, the condition that the data can be obtained from the cache library is satisfied, that is, the data obtaining request should be at least a second data obtaining request, so that the cache library can only have the related cache data for obtaining. Of course, the data fetch request may be the first data fetch request, but it is likely that no relevant data can be found in the cache library.
When the client sends a data acquisition request for the first time, the cache library does not have data corresponding to the data acquisition request, at this time, corresponding data needs to be acquired from the database of the server, and after the corresponding data is acquired, the data is correspondingly placed into the cache library for the next data request to be acquired. Taking the currently generated data acquisition request as the current data acquisition request, a time difference, that is, a difference value of request time, that is, the request time interval mentioned in the embodiment of the present application must exist between the current data acquisition request and the data acquisition request initiated for the first time.
S3, if the time interval is greater than the validity period of the cache data and less than the expiration period of the cache data, sending a first feedback data and a second feedback data to the client, where the first feedback data is the cache data, the second feedback data is the updated cache data, the second feedback data is sent after the first feedback data, and the sending time interval between the second feedback data and the first feedback data is less than or equal to the display time of the first feedback data at the client, the validity period of the cache data is the time period when the cache data is invalid, and the expiration period of the cache data is the time period when the cache data is cleared.
In general, in order to ensure timeliness of the cached data in the cache library, deletion and update processing of the data in the cache library is required. At this time, an expiration date and an expiration date are set for the cache data, and the start times of the two dates are the time when the data acquisition request is first generated. If the time interval is greater than the validity period of the cache data and less than the expiration period of the cache data, it indicates that the initiation time of the current data acquisition request does not exceed the deletion time of the cache data, that is, the cache data still exists in the cache library, but since the current time exceeds the validity period of the cache data, it indicates that the cache data needs to be updated, otherwise, the timeliness of the cache data cannot be met, and therefore, the feedback data finally sent to the client side should be the updated cache data. However, in the process of updating the cache data, a certain time is consumed, and if no feedback is given to the client in the time, the user is enabled to wait for the feedback, so that the experience of the user is reduced. In order to solve the problem, in the embodiment of the application, first feedback data, that is, cache data, is sent to a user, at this time, the cache data exists in a cache library and corresponds to a data acquisition request, but only lacks a certain timeliness, but the data is fed back to a client first for use by the user, so that waiting of the user can be avoided, and meanwhile, the first feedback data also has a certain reference value, so that a value can be brought to the user to a certain extent. In the process that the user browses the first feedback data, the server acquires cache data needing to be updated from the database to the cache library, acquires second feedback data corresponding to the data acquisition request from the cache library, and feeds the second feedback data back to the client so that the user can browse the real feedback data.
It should be noted that the time difference between the second feedback data and the first feedback data is less than or equal to the time of the first feedback data displayed on the client, so that the problem of data blank is avoided, and the user can browse the data all the time.
Further, as shown in fig. 2, a flowchart of a method for sending second feedback data provided in the embodiment of the present application is provided, where the method includes:
s211, acquiring target data from a database according to the data acquisition request, wherein the target data are data matched with the data acquisition request in the database;
s212, replacing the cache data with the target data to obtain updated cache data;
and S213, sending the updated cache data serving as second feedback data to the client.
As can be seen from the foregoing, the second feedback data is updated cache data, and the cache data is updated from the database, so the second feedback data is also data obtained from the database, and in order to match the data obtaining request, the part of the data needs to be target data obtained from the database and matching the data obtaining request. At this time, the cache data which is invalid in the cache library needs to be updated by using the acquired target data, so that the updated cache data can be sent to the client as second feedback data for the client to use the latest data, and the timeliness of the data acquired by the client is ensured.
In one implementation, if the time interval is less than or equal to the validity period of the cached data, the first feedback data is sent to the client.
At this time, it is described that the cache data in the cache library still has timeliness, and the requirement of the client for data novelty is met, so that the first feedback data, namely the cache data, can be directly sent to the client for the client to display.
In one implementation manner, as shown in fig. 3, a flowchart of a method for determining third feedback data provided in an embodiment of the present application is provided, where the method includes:
s311, if the time interval is greater than or equal to the expiration date of the cache data, sequencing preselected data in a database to obtain a first sequence, wherein the preselected data are data which accord with preset preliminary screening conditions in the database;
s312, sequentially browsing each preselected data in the first sequence in combination with the data obtaining request to determine a third feedback data, where the third feedback data is the preselected data corresponding to the data obtaining request.
If the time interval is greater than or equal to the expiration date of the cache data, it indicates that the cache data needs to be deleted, at this time, the cache data corresponding to the data acquisition request cannot be acquired from the cache library, and at this time, corresponding feedback data needs to be acquired from the database according to the data acquisition request. At the moment, all data in the database are screened, and data which are not consistent with preset preliminary screening conditions are removed, so that preselected data are obtained, the range of the data to be inquired can be effectively reduced, and the efficiency of subsequently acquiring the data is improved. These preselected data are then sorted to obtain a first sequence. At this time, according to the arrangement sequence of each preselected data in the first sequence, each preselected data is matched, so that third feedback data matched with the data acquisition request is determined, each preselected data is sequentially matched according to the first sequence, data loss can be avoided, repeated matching of data can also be avoided, and the data matching efficiency is ensured.
Further, as shown in fig. 4, a flowchart of a method for obtaining a first sequence provided in an embodiment of the present application is provided, where the method includes:
s3111, combining preset ordering influence dimensions, and calculating weights corresponding to the preset ordering influence dimensions by using an ordering algorithm;
s3112, calculating an addition and an average value of products of each subdata in each piece of preselected data and the corresponding weight to obtain a score of each piece of preselected data;
s3113, obtaining a first sequence consisting of the preselected data by arranging the scores.
The ordering of the data may be influenced by the weight, i.e. the data ordered first may correspond to the data ordered later with a higher weight. Usually, a weight corresponding to each preset ordering influence dimension, such as a distance, a cost, etc., is calculated according to the preset ordering influence dimension. Each piece of pre-selected data is usually composed of a plurality of sub-data, for example, order data, including sub-data such as distance, unit price, oil consumption, waiting time, etc., each sub-data corresponds to a weight, and the score of the pre-selected data corresponding to the sub-data can be obtained by multiplying the sub-data by the respective weight, and adding and averaging the products. The preselected data may then be ranked according to the score of each preselected data to obtain a first sequence. Therefore, the generation method of the first sequence provided by the embodiment of the application can comprehensively consider various weight factors influencing the sorting, so that the arrangement mode of each preselected data in the first sequence is adjusted by adjusting the weight value to generate the first sequence meeting the sequence of the matched data.
Further, as shown in fig. 5, a flowchart of an index generating method provided in an embodiment of the present application is shown, where the method includes:
s411, correspondingly generating an index from the first sequence, wherein the index and the first sequence have a one-to-one correspondence relationship;
s412, the index is placed into a cache, so that the data processor determines the corresponding first sequence according to the index.
Because the first sequence contains a large amount of preselected data, the data size is large, and if the first sequence is directly put into the cache library, a large amount of memory of the cache library is occupied, so that the available space of the cache library is reduced. At this time, an index is generated for the first sequence and is placed in the cache library, the corresponding first sequence can be determined through the index, and the volume of the index is greatly reduced compared with that of the first sequence, so that the occupation of the cache library can be effectively reduced. Meanwhile, the number of the first sequences can be generated according to actual requirements, and correspondingly, the cache library can simultaneously contain a plurality of indexes so as to determine different first sequences.
In one implementation manner, the expiration date of the cached data is taken as a period, and a second sequence is automatically created for an active client to use, where the active client is a client that sends the data acquisition request with a frequency greater than or equal to a preset frequency.
For some active clients that may initiate data acquisition requests periodically, if operations such as updating cache data are performed after each data acquisition request is initiated, a problem of data acquisition waiting may occur, so as to affect the experience of the user. Therefore, prejudgment can be made for the active users, namely cache data related to the data acquisition requests of the active users are updated regularly, namely the second sequence is created automatically, so that when the active users initiate the data acquisition requests, the latest cache data can be searched from the second sequence of the cache library at any time. The second sequence may be the same as or different from the first sequence.
In one implementation manner, as shown in fig. 6, there is provided a flowchart of a method for requesting a wait processing according to an embodiment of the present application, where the method includes:
s511, acquiring the total number of the to-be-processed requests corresponding to the request time, wherein the to-be-processed requests are data acquisition requests sent by each client;
and S512, if the total number is greater than or equal to a preset number threshold, sending preset feedback data to each client, and processing each request to be processed one by one.
For the situation of high concurrency of data acquisition requests, once the total number of the to-be-processed requests corresponding to the request time exceeds a preset number threshold, the processing capacity of the server for the data acquisition requests is saturated, and if the processing is continued, exceptions and errors occur. At this time, it is necessary to adopt the fusing process, i.e., not to process too many data acquisition requests. However, if no data is fed back to the client, the user may have a poor experience, and at this time, preset feedback data may be sent to the client, and the feedback data does not occupy the processing resource of the server, but the user may feel feedback of the data to ensure the experience. Meanwhile, the requests to be processed, which cannot be processed at the current moment, are delayed one by one rather than discarded, so that the data acquisition requests of the client are effectively processed.
