Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular, to a data query method, apparatus, device, and storage medium. Background Art

[0002] With the development of big data technology, the lakehouse architecture has been recognized by more and more customers and applied to the actual environment. The data in the lakehouse architecture is stored separately in the data lake component. Therefore, when querying data, it is necessary to query in the data lake component, and the query speed is relatively slow.

[0003] To solve the problem of relatively slow query speed, every time the user terminal obtains a query result, it will store the query result in the local disk. Then, when querying based on the same query conditions next time, it will first query in the local disk. If the query fails, it will then query from the data lake component.

[0004] However, due to the small size of the user terminal, the storage capacity of its local disk is limited. To avoid the local disk affecting the performance of the user terminal, the user terminal will regularly clear historical data or use new query results to overwrite old query results, resulting in a relatively large amount of calculation for re-querying in the data lake component based on previous query conditions.

[0081] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application.

[0082] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0083] With the development of big data technology, the lakehouse architecture has been recognized by more and more customers and applied to actual environments. The data of the lakehouse architecture is stored separately in the data lake component. Therefore, when querying data, it is necessary to query in the data lake component, and the query speed is relatively slow. To solve the problem of relatively slow query speed, every time the user terminal obtains a query result, the query result will be stored in the local disk. Then, when querying again based on the same query conditions next time, the query will be first performed in the local disk. If the query fails, the query will be performed in the data lake component. However, due to the small size of the user terminal, the storage capacity of its local disk is limited. To avoid the local disk affecting the performance of the user terminal, the user terminal will regularly clear historical data or use new query results to overwrite old query results, resulting in a relatively large amount of calculation for re-querying in the data lake component based on previous query conditions.

[0084] To solve the above problems, an embodiment of the present application provides a data query method, which is applied to the Figure 1 structure shown. Among them, the user terminal is an intelligent device such as a mobile phone, a tablet computer, or a notebook. The user can trigger a data query operation in the user terminal, and then generate a query request according to this operation, and send the query request to the proxy service. The proxy service is a server for data forwarding and related processing. The proxy service can receive the query request sent by the user terminal and send the query request to the query service. The query service is used to query based on the query request in the historical query results and send the target result to the proxy service. When the proxy service receives the target result, the proxy service detects whether the target result includes the target query result. When the target result includes the target query result, the proxy service forwards the target query result to the user terminal. When the target result does not include the target query result, the proxy service sends the query request to the data lake component set to obtain the target query result in the data lake component set. When the proxy service receives the target query result obtained in the data lake component set, the proxy service sends the target query result to the user terminal and the query service.

[0085] In summary, an embodiment of the present application provides a data query method. Since the query service in this method does not need to regularly clear the historical query results or use new query results to overwrite the old query results, it can re-query in the query service based on the previous query conditions, reducing the amount of calculation. As Figure 2 shown, the specific steps include:

[0086] Step 201, receive the query request sent by the user terminal.

[0087] Among them, the query request includes the target query condition.

[0088] In this step, the user terminal can display a data query page, which includes a keyword input box and a query button. The user can enter a keyword in the keyword input box and click the query button. When the user terminal detects the trigger operation of the query button, it obtains the keyword in the keyword input box, generates a query request based on the keyword, and sends the query request to the proxy service so that the proxy service receives the query request.

[0089] Alternatively, the data query page includes multiple condition options and an OK button. The user can select the condition options and click the OK button. When the user terminal detects the trigger operation of the OK button, it obtains the selected conditions, generates a query request according to these conditions, and sends the query request to the proxy service so that the proxy service receives the query request.

[0090] Of course, other methods can also be used to trigger the client to generate a query request, which is not limited here.

[0091] Step 202: Send the query request to the query service so that the query service can perform a query according to the target query condition and return a target result.

[0092] Among them, the query service stores historical query results. In the embodiments of the present application, when it is necessary to use the data lake component to perform a data query, the data lake component will send the query result to the proxy service so that the proxy service can send the query result to the query service for storage. Based on such a method, historical query results will be stored in the query service.

[0093] In this step, the proxy service sends the query request to the query service. When the query service receives the query request, it parses the query request to obtain the target query condition, and then performs a query according to the target query condition to obtain a target result and returns it to the proxy service.

[0094] It should be noted that according to the target query condition, the query service may or may not query the corresponding result. Therefore, the target result may or may not include the query result.

[0095] Step 203: When the target result includes the target query result, send the target query result to the client so that the client can perform corresponding processing based on the target query result.

[0096] Among them, the target query result is the query result corresponding to the target query condition, that is, the query result obtained by performing a query based on the target query condition.

[0097] In this step, it is detected whether the target result includes the target query result. When the target result includes the target query result, the target query result is sent to the client so that the client can perform display or other processing based on the target query result.

[0098] Furthermore, when the query service fails to find the target query result, it will return a preset result to the proxy service to inform the proxy service that the target query result has not been queried. In this way, when the proxy service receives the target result returned by the query service, it detects whether the target result is the preset result. When the target result is not the preset result, it is determined that the target result includes the target query result. When the target result is the preset result, it is determined that the target result does not include the target query result. Among them, the preset result is used to indicate that the target query result has not been queried.

[0099] Further, a target parameter can be set in the target result. By detecting whether the target parameter is a preset value, it is determined whether the target result includes the target query result. The specific steps include: obtaining the target parameter in the target result, detecting whether the target parameter is a preset parameter. When the target parameter is a preset parameter, it is determined that the target result includes the target query result. When the target parameter is not a preset parameter, it is determined that the target result does not include the target query result.

[0100] Of course, other methods can also be used in this step to detect whether the target result includes the target query result, which is not limited here.

[0101] In the embodiment of the present application, a query request sent by the user terminal is received. The query request includes a target query condition; the query request is sent to the query service so that the query service performs a query according to the target query condition and returns a target result; when the target result includes the target query result, the target query result is sent to the user terminal so that the user terminal performs corresponding processing based on the target query result; where the target query result is the query result corresponding to the target query condition. It can be seen that the present application first performs a query in the query service, and the query service is not affected by the user terminal, and there is no need to regularly clear the historical query results or use new query results to overwrite the old query results. Therefore, it is possible to re-query in the query service based on the previous query conditions, reducing the amount of calculation.

[0102] Based on the above embodiment of the application, when the target result does not include the target query result, the proxy server needs to send the query request to the data lake component so that the data lake component performs a data query based on the query request. However, if the query is performed based on all data lake components, it will take a lot of time. Therefore, the proxy service can also determine the first component to be used according to the target business type in the query request, and then perform a data query in the first component. Therefore, the embodiment of the present application provides a method for performing data query based on the first component. The method is as Figure 3 shown, and the specific steps include:

[0103] Step 301, when the target result does not include the target query result, determine the first component to be used in the data lake component set according to the target business type.

[0104] Among them, the data lake component set includes multiple subsets, each subset corresponds to a business type, and each subset includes at least one data lake component.

[0105] In this step, when the target result does not include the target query result, it indicates that the query service has not queried the target query result. Therefore, the proxy service can determine the subset corresponding to the target business type according to the target business type in the query request, and determine the data lake components in this subset as the first components to be used.

[0106] Step 302: Send the query request to the first component so that the first component uses the target query condition to perform a query and obtain the target query result.

[0107] In this step, the proxy service can send the query request to the first component so that the first component performs a query based on the target query condition, obtains the target query result, and returns the target query result to the proxy service.

[0108] Furthermore, when there are multiple first components, the proxy service can send the query request to each first component and receive the results returned by each first component. Then, the proxy service performs related processing such as fusion and filtering on these results to obtain the target query result. Or, the proxy service sends the query request to the management device of the first component so that the management device returns the target query result.

[0109] In the implementation of this application, as Figure 4 shown, the query service includes query services corresponding to different data lake components. In this case, the proxy service needs to determine the second component to be used according to the target business type in the query request, and then perform a query in the query service corresponding to the second component according to the target query condition to obtain the target result. Therefore, the embodiments of this application provide a method for determining the target result, and the method is as Figure 5 described, and the specific steps include:

[0110] Step 501: Determine the second component to be used in the data lake component set according to the target business type.

[0111] This step is similar to step 401 and will not be elaborated here one by one.

[0112] Step 502: Send the query request to the query service corresponding to the second component so that the query service corresponding to the second component performs a query according to the target query condition, obtains the target result, and returns the target result.

[0113] Among them, the data lake component set includes multiple subsets, each subset corresponds to a business type and a query service, and the query service corresponding to this subset stores the historical query results obtained based on this subset, that is, when a query result is obtained based on a certain subset, the query result is stored in the query service corresponding to this subset.

[0114] In this step, the proxy service sends the query request to the query service corresponding to the second component. After receiving the query request, the query service performs a query according to the target query condition. When the target query result is found, the target result is obtained based on the target query result. When the target query result is not found, the preset result is determined as the target result, and then the target result is sent to the proxy service.

[0115] It should be noted that when the target result includes the target query result, the proxy service sends the target query result to the proxy service. When the target result does not include the target query result, the proxy service sends the query request to the second component so that the second component performs a query based on the target query condition to obtain the target query result.

[0116] In the embodiment of the present application, the query service stores the corresponding relationship between the query condition and the query result. Therefore, the query service can perform a query according to the target query condition and this corresponding relationship to obtain the target result. Therefore, the embodiment of the present application provides a method for determining the target result, and the method is as Figure 6 shown, and the specific steps include:

[0117] Step 601, obtain the corresponding relationship between the pre-created query condition and the query result.

[0118] In this step, the query service can receive the query condition and the query result sent by the proxy service, and create the corresponding relationship between the query condition and the query result based on the query condition and the query result.

[0119] It should be noted that when the proxy service receives the target query result returned by the first component, the proxy service sends the target query result and the target query condition to the query service so that the query service establishes a corresponding relationship based on the target query result and the target query condition. The specific steps are: obtain the target query result obtained based on the first component; send the target query condition and the target query result to the query service so that the query service stores them based on the target query condition and the target query result.

[0120] Step 602, in the corresponding relationship, detect whether there is a target query result corresponding to the target query condition.

[0121] Wherein, the target query result is the query result corresponding to the target query condition.

[0122] In this step, in the corresponding relationship between the query condition and the query result, detect whether there is a target query result. When there is a target query result, the target query result can be directly determined as the target result for return.

[0123] Step 603, when there is a target query result corresponding to the target query condition, obtain the target result according to the target query result.

[0124] In this step, when there is a target query result, the target result can be generated according to preset parameters and the target query result, or the target result can be generated only based on the target query result, which is not limited here.

[0125] Step 604, when there is no target query result corresponding to the target query condition, use a preset result determination strategy to determine the target result.

[0126] In this step, when there is no target query result, there are two cases. One is that the target query result can be determined based on the existing historical query results, and the other is that the target query result cannot be determined based on the existing historical query results, and only the preset result can be returned to the proxy service. Based on the above situation, the query service is set with a result determination strategy, and then based on this result determination strategy, the target result is determined.

[0127] Step 605, send the target result to the proxy service.

[0128] In this step, the query service sends the target result to the proxy service so that the proxy service can perform corresponding operations according to the target result.

[0129] In the embodiment of the present application, when there is no target query result in the query service, the target query result may also be calculated based on some query results. This situation often occurs when the target query condition includes multiple sub-conditions. When the target query condition includes multiple sub-conditions, the query service can find the query results that meet at least one sub-condition, and then based on these query results, detect whether there is a target query result corresponding to the target query condition, and then obtain the target result. Therefore, the embodiment of the present application provides a method for determining a target result, and this method is as Figure 7 shown, and the specific steps include:

[0130] Step 701, combine multiple sub-conditions to obtain a reference query condition corresponding to each combination method.

[0131] In this step, combine multiple sub-conditions to obtain all combination methods, and obtain the corresponding reference query condition for each combination method.

[0132] For example, assume that the target query condition includes three sub-conditions A, B, and C. The reference query conditions obtained based on this target query condition are A, B, C, AB, AC, and BC.

[0133] Step 702, in the corresponding relationship, determine the reference result set corresponding to each reference query condition.

[0134] For example, assume that the reference query conditions are A, B, C, AB, AC, and BC. Then, determine the reference result sets corresponding to A, B, C, AB, AC, and BC respectively.

[0135] Step 703, when there is a target object in the reference result sets, obtain a target query result according to the target object, and determine a target result according to the target query result.

[0136] Among them, each reference result set includes at least one object, and these objects all meet the corresponding reference query conditions. The target object is the object that exists in all reference result sets, which is the intersection of all reference result sets, that is, the target object is in all reference result sets.

[0137] In this step, compare the objects in these reference result sets, determine the objects included in all reference result sets, and determine these objects as target objects. Combine these target objects to obtain a target query result, and then determine a target result according to the target query result.

[0138] For example, in the reference result sets corresponding to A, B, C, AB, AC, and BC respectively, find the objects that these reference result sets have in common, determine this object as the target object, and obtain a target query result according to the target object.

[0139] It should be noted that if the query condition further includes an aggregation condition, the target object can also be divided according to this aggregation condition to obtain at least one target object set, and each target object set is aggregated to obtain a target query result. For example, the aggregation condition is to aggregate the objects belonging to the same user. Therefore, find the target objects belonging to the same user among these target objects to obtain at least one target object set, and aggregate each target object set to obtain a target query result.

[0140] Step 704, when there is no target object in the query result set, determine the preset result as the first query result.

[0141] Among them, the preset result is used to indicate that no target query result is found.

[0142] In the embodiments of the present application, the query service stores the result sets corresponding to each service type. Therefore, the target result set corresponding to the target service type can also be determined according to the target service type in the query request, and then the target result is queried in this target result set according to the target query condition and returned. Therefore, the embodiments of the present application provide a query method based on a query result set, and the method is as Figure 8 shown, and the specific steps include:

[0143] Step 801: Obtain the target result set corresponding to the target service type.

[0144] In this step, the query service stores the result set corresponding to each service type. Therefore, when the query service obtains the target service type in the query request, it determines the result set corresponding to the target service type and determines this result set as the target result set.

[0145] Step 802: Query according to the target query condition in the target result set and return the target result.

[0146] In this step, only when a query result that meets the target query condition is found in the target result set, so it is possible to query in the target result set according to the target query condition. Therefore, compared with finding results among all query results, the embodiments of the present application can save certain computing resources.
