Background

With the development of computer networks, more and more users deal with daily demands such as purchasing daily necessities, train tickets, airline tickets, movie tickets and the like through an electronic commerce platform. General large-scale e-commerce websites usually store tens of millions of user, commodity, ordering data and the like, and it can be concluded according to the generally accepted twenty-eight law that only 20% of hot spot data are accessed and operated by a large number of users, and 80% of data are zombie data and are rarely operated. The hotspot data is data corresponding to a hotspot request of a user and can be divided into static hotspot data and dynamic hotspot data. Static hotspot data may be understood as hotspot data that can be predicted in advance. If the hot spot data is screened out in advance in a buyer registration reservation mode, the predicted hot spot data is marked in advance. In addition, hot commodities can be found in advance through big data analysis so as to analyze hot data. However, the dynamic hot spot data cannot be predicted in advance and is a hot spot temporarily generated in the operation process of the system. Merchants have passed various modes of publicity or some unpredictable situation (e.g., new crown pneumonia causes a sudden increase in mask search volume) that causes it to become hot data in a short period of time.

In the process of implementing the invention, the inventor finds that at least the following technical problems exist in the prior art: the dynamic hotspot data is based on temporarily generated hotspots, so that more intervention cannot be performed on the hotspots.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of an information query method according to an embodiment of the present invention. The embodiment is applicable to the situation when responding to the information inquiry request initiated by the user. The method may be performed by an information query apparatus, which may be implemented in software and/or hardware, for example, the information query apparatus may be configured in a computer device. As shown in fig. 1, the method includes:

s110, responding to the detected information inquiry request, and acquiring an inquiry identifier of the information inquiry request.

In this embodiment, the information query request may be a request initiated by a user through a user side and used for querying the target query information. The query identifier may be obtained by parsing the information query request. It is understood that the query identifier may be determined based on a query keyword input by a user, which may be an item identifier of a target query item associated with the information query request, or an information identifier of target query information associated with the information query request. Illustratively, when a user needs to purchase a mask, an information query request for querying relevant information of the mask is triggered by clicking a query control after inputting the mask on a user terminal, the user terminal generates the information query request based on the mask input by the user and sends the information query request to a server terminal, and the server terminal analyzes the information query request and obtains the mask carried in the information query request as a query identifier.

And S120, acquiring target query information corresponding to the query identifier according to the query dimension parameter based on a preset master-slave query mechanism.

Generally, most of the data stored in the cache is static hotspot data which can be predicted in advance. Therefore, when a certain type of data is suddenly changed into dynamic hot spot data, the data in the cache cannot meet the query requirements (such as the requirements on the information quantity, the information accuracy and the like) of the dynamic hot spot data, that is, the real-time performance and the accuracy of the dynamic hot spot data in the information queried from the cache are poor. In order to solve the technical problem that the real-time performance and the accuracy of dynamic hot data are poor and improve the query performance of a foreground list, in the embodiment, a master-slave query mode is adopted, query dimension parameters are set at the same time, and target query information corresponding to a query identifier is obtained by combining a master-slave query mechanism and the query dimension parameters, so that the real-time performance and the accuracy of the dynamic hot data in the target query information are improved. In general, when an information query request initiated by a user is received, an application server firstly queries a cache, and when data in the cache, which accord with the information query request, does not reach a set dimension parameter, a secondary query operation is triggered, and the data which accord with the information query request are obtained from a database so as to improve the real-time performance and the accuracy of dynamic hot data in target query information. In the above process, two query dimension parameters may be included: a master query dimension parameter and a slave query dimension parameter. Optionally, whether the slave query operation needs to be started or not may be determined based on the master query dimension parameter, and the slave query operation may be executed based on the slave query dimension parameter. It can be understood that the master query dimension parameter and the slave query dimension parameter can be set according to actual requirements.

And S130, generating response information of the information inquiry request based on the target inquiry information and responding.

In this embodiment, after the target query information is obtained, the target query information may be directly sent to the user side as response information of the information query request for response, or the target query information may be combined with other information to generate response information of the information query request, and the response information is sent to the user side for response.

Example two

Fig. 2 is a flowchart of an information query method according to a second embodiment of the present invention. The embodiment is further optimized on the basis of the scheme. As shown in fig. 2, the method includes:

s210, responding to the detected information inquiry request, and acquiring an inquiry identifier of the information inquiry request.

S220, obtaining target cache information corresponding to the query identifier from the data cache cluster, and judging whether the target cache information meets a main query dimension parameter associated with a main query operation.

In this embodiment, the primary query dimension parameter is used to determine whether the target cache information obtained by the primary query operation meets the query requirement. Optionally, the main query operation may be understood as pulling target cache information associated with the query identifier from the data cache cluster, and after the main query operation is performed to obtain the target cache information, determining whether the pulled target cache information meets a query requirement based on the main query dimension parameter.

Optionally, in order to improve the user experience, the main query dimension parameter may be set as a main number dimension parameter, that is, the lowest number of pieces of target cache information that is pulled, so that when the number of pieces of target cache information is smaller than the set lowest number, more information is obtained from the query operation, and the display effect of the target query information is improved. It can be understood that, when the main query dimension parameter is the lowest number of parameters, the main query dimension parameter for determining whether the target cache information satisfies the main query operation association may be: and judging whether the number of the target cache information is greater than the lowest number, judging that the target cache information meets the main query dimension parameter when the number of the target cache information is greater than the lowest number, and judging that the target cache information does not meet the main query dimension parameter when the number of the target cache information is not greater than the lowest number.

And S230, when the target cache information meets the main query dimension parameter, responding by taking the target cache information as the target query information.

When the target cache information meets the main query dimension parameter, the target cache information can meet the query requirement of a user, and the target cache information is directly used as the target query information to respond.

And S240, when the target cache information does not meet the main query dimension parameter, calling a middle station interface to acquire target updating information associated with the query identifier.

And when the target cache information does not meet the main query dimension parameter, the target cache information is represented as incapable of meeting the query requirement of the user, a slave query operation is triggered, and a middle station interface is called to obtain target update information associated with the query identifier. Optionally, the querying the dimension parameter further includes calling a middlebox interface to obtain target update information associated with the query identifier from the querying dimension parameter, including: and asynchronously initiating a middle platform interface call through the custom thread pool, and acquiring target updating information based on the query dimension parameters. Optionally, the user-defined thread pool may be used to asynchronously initiate a middle platform interface call to initiate multiple slave queries, so as to accelerate the acquisition speed of the target update information. The secondary query dimension parameters can be set according to actual requirements, the number of the secondary query dimension parameters can be one or more, and the secondary query dimension parameters can be the intersection or union of different dimension parameters. And when the slave query operation meets the preset slave query dimension parameter, using the target updating information acquired from the query operation as the supplementary information of the target cache information. In one embodiment, the secondary query dimension parameters include a query duration dimension parameter and/or a secondary number dimension parameter. The query duration dimension parameter and the slave number dimension parameter may be set at different levels, that is, the slave query dimension parameter may be an intersection or a union of the query duration dimension parameter at different levels and the slave number dimension parameter at different levels. When the slave query dimension parameter is the intersection of the query duration dimension parameter and the slave number dimension parameter, the target update information can stop the slave query operation only when the duration dimension parameter and the slave number dimension parameter are simultaneously satisfied; when the slave query dimension parameter is the union of the query duration dimension parameter and the slave number dimension parameter, the target update information can stop the slave query operation only by meeting any one of the duration dimension parameter and the slave number dimension parameter.

And S250, generating target query information based on the target cache information and the target updating information for responding, and caching the target updating information into the data cache cluster.

In this embodiment, after the target update information is obtained, the target cache information and the target update information may be summarized as the target query information to be responded. The target cache information can also be returned to the user side for displaying, so that the situation that the user waits for a long time or an empty list appears is avoided, and the target update information is returned to the user side for displaying after the target update information is obtained from the query operation, so that the information display effect and the user experience are improved.

In order to improve the real-time performance and accuracy of the dynamic hotspot data in the cache, after the target update information is obtained, the target update information needs to be stored in the cache, that is, the target update information is cached in the data cache cluster. In one embodiment of the present invention, caching target update information in a data cache cluster includes: acquiring information change parameters of a supplementary information identifier of the supplementary information to be inquired in the data cache cluster; and determining the cache target time length of the query supplementary information according to the information change parameters, and caching the query supplementary information into the data cache cluster based on the cache target time length. Optionally, in order to avoid avalanche caused by cache penetration due to improper data cache duration, in this embodiment, the cache target duration of the target update information is reasonably determined based on the update frequency of the target update information. The information change parameter of the supplementary information identifier can be understood as the change frequency of the history information of the target update information supplementary information identifier in the cache. The cache is carried out by adopting a simple cache cluster and a determination mode of cache target duration, so that the original data structure is hardly changed during data cache, the technical problems of high delay, inaccuracy and the like caused by data synchronization by adopting a data synchronization mechanism of middleware such as mq, zookeeper and the like or a database binlog log monitoring synchronization mechanism are solved, and the complexity of the sniffing mechanism and the data compensation mechanism scheme is reduced.

For example, assuming that the information identifier of the target update information is "1", historical information content corresponding to the information identifier "1" in the cache within a certain period of time is acquired, an information change parameter of the information identifier "1" is determined based on the historical information content, and a cache target duration of the target update information is determined according to the information change parameter of the information identifier "1". It can be understood that, when the change frequency of the information is higher, it indicates that the number of times the information is queried is higher, that is, the data is frequently changed, and in order to ensure the real-time performance and accuracy of the data, the cache target duration of the information needs to be set shorter; when the change frequency of the information is smaller, it indicates that the number of times the information is queried is smaller, that is, the data is not frequently changed, and the cache target duration of the information may be set longer.

In one embodiment, the determining, by the information change parameter, a cache target duration for querying the supplemental information according to the information change parameter includes: and carrying out weighted summation on the information change time and the basic cache time to obtain the cache target time. The information change time may be understood as a time difference between the latest change time of the information content identified by the supplemental information and the current time. The longer the time difference between the change time and the current time is, the data is changed less, and the cache target duration of the data can be set longer; the smaller the time difference between the change time and the current time is, the data is frequently changed, the shorter the cache target time of the data needs to be set, and the latest data can be obtained in time conveniently. On the basis, the weights of the information change time and the basic cache duration can be set, and the information change time and the basic cache duration are weighted and summed to obtain the cache target duration. For example, the cache target duration of the query supplemental information may be calculated by f (n) ═ ax + b. Wherein, f (n) is the cache target duration for inquiring the supplementary information; a is a coefficient which can be set according to actual requirements; x is the information change time of the supplementary information identifier of the query supplementary information, and b is the basic cache duration. By the method, the effective cache duration of the hot spot data can be accurately set, so that the effective durations of all the hot spot cache data are dynamically and randomly tiled according to the time dimension, large-area cache invalidation can not occur, and system avalanche caused by cache penetration is avoided. The basic caching duration can be set according to the type of the supplementary information identifier. When the type to which the supplementary information identifier belongs is the type with higher change frequency, the basic cache duration can be set to a smaller value so as to ensure the real-time performance and accuracy of the data, and when the type to which the supplementary information identifier belongs is the type with lower change frequency, the basic cache duration can be set to a larger value so as to reduce the resource waste caused by frequently calling the data from the middle interface.

On the basis of the embodiment, the target query information corresponding to the query identifier is obtained according to the preset query dimension parameter based on the preset master-slave query mechanism, whether the slave query operation is triggered is judged according to the master dimension parameter, and the target update information is obtained through the slave dimension parameter when the slave query operation is triggered so as to supplement the target cache information, so that the dynamic hot data in the target query information is real-time and accurate data, and the user experience is improved. In addition, by reasonably determining the cache target duration of the target update information in the cache, the avalanche caused by cache penetration is avoided: the complexity of the sniffing mechanism and the data compensation mechanism scheme is reduced.

EXAMPLE III

The present embodiment provides a preferred embodiment based on the above-described embodiments. In the embodiment, characteristics and requirements of the dynamic hot spot data are combined, and a technical scheme for improving real-time performance and accuracy of the dynamic hot spot data is provided. The features of the dynamic hot spot data can be summarized as follows: the total data volume is not large, but the data has great importance and great influence on the service; data is frequently retrieved, the overall dynamic change is not large, only local attributes are updated, and once the local attributes are updated, the local attributes are presented immediately (the time for data inconsistency is shortened as much as possible); the retrieval performance of hot spot data must be considered, and the consistency and real-time performance of the data are ensured; high availability and horizontal capacity expansion of dynamic hotspot data are ensured; zombie data revived and the acuity when programming hot spot data was lower.

Fig. 3 is a flowchart illustrating an information query method according to a third embodiment of the present invention. As shown in fig. 3, in order to improve the foreground list query performance, a design scheme of master-slave query (AB query for short) is adopted in the query process; meanwhile, query dimensions, such as a query duration dimension or a minimum number dimension, are set (the query dimensions can be customized according to business requirements, and the dimensions can be union or intersection), so that the real-time performance and accuracy of the hot data are improved, and the user experience is improved. Specifically, the application service queries the cache cluster first, and if the data in the cache reaches one or more set dimensions, one-time query completion is indicated (at this time, only the main query is triggered to meet the requirement); if the set dimensionality is not met in the cache cluster, the triggering of the primary query cannot meet the requirement, the data captured by the primary query from the cache is returned to the front end, and the condition that a user waits for a long time and finally generates an empty list is avoided; and then, asynchronously initiating a middle platform interface call by using a self-defined thread pool, initiating multiple times of secondary queries at the moment, continuously querying the cache cluster according to a defined interval from the secondary queries, returning data as long as any query dimension is met, and continuously supplementing and updating the data list of the user.

When the data acquired from the query is cached in the data cache cluster, the effective duration of the cached data can be reasonably determined through the change frequency of the data, and avalanche caused by cache penetration is avoided. On the other hand, the effective duration of the cache data can be flexibly adjusted, the data in the DB can be timely written back to the cache after being updated, and the real-time performance of the cache data is improved. When the time consumption of data synchronization is compressed as much as possible, the simplest data synchronization mode is used, the complexity of data compensation is reduced, and cache data dirty reading caused by inaccurate data is avoided. For a specific determination manner of the valid duration of the cache data, reference may be made to the above embodiments, and details are not described herein again.

In summary, in this embodiment, a data synchronization mechanism of middleware such as mq and zookeeper is not adopted during data caching, and a database binlog log monitoring synchronization mechanism is not used; but adopts a simple cache cluster combined with a design on business, naturally supports a distributed environment, and hardly changes the original data structure. The technical problems that failure and heavy consumption prevention are inevitably considered when mq is used are solved, the technical problems that log analysis sequence and analysis failure are inevitably considered when binlog is used are solved, and the technical problem that the complexity of projects introduced by using zookeeper as a third party for monitoring is solved. In addition, the technical problem that data must be synchronized for multiple times in other compensation modes when data synchronization fails in the synchronization mechanism is also avoided, for example, the binlog analysis of a database fails, and manual intervention compensation is necessary, which easily causes the occurrence of data sequentiality and ABA problems; with mq asynchronous consumption, problems of consumption exception, repeated consumption, how to compensate after consumption failure and the like must be considered.

According to the embodiment, the validity period of the cache data is reasonably determined, so that the real-time performance and the accuracy of the dynamic hot data are improved, and avalanche caused by cache penetration is avoided; the complexity of a sniffing mechanism and a data compensation mechanism scheme is reduced by combining the cache cluster to cache data; the real-time performance and accuracy of the hot data are improved by combining a master-slave query mechanism and a query dimension, and the user experience is improved.
