Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of Internet, in particular to a request processing system. BACKGROUND

[0002] With the development of Internet technology, shopping through an e-commerce platform is becoming more and more popular. In the e-commerce field, the amount of requests accepted by the background server of the e-commerce platform is very large. In order to improve the reading speed of data, the background server usually caches the data in the database, so that the terminal can directly read the data from the cache without accessing the database, thereby reducing the pressure on the database and improving the performance of the server. Although the cache can improve the performance of the server, improper use of the cache can cause cache avalanche, cache penetration, and cache and database double-write consistency problems. Therefore, how to correctly use the cache is a technical problem to be solved.

[0003] In the related art, the server usually uses the method of deleting the cache first and then updating the database to solve the inconsistency between the cache and the database data. Accordingly, when the data in the database changes, the server first deletes the cache, then modifies the database, and then stores the updated data in the cache, thereby avoiding the inconsistency between the cache and the database data.

[0004] However, in a high-concurrency environment, the server will concurrently process a large number of data requests. In the case of concurrently reading data requests and updating data requests for any data, after the server deletes the cache, it immediately reads the cache. At this time, the cache read is empty and the database has not been updated, so a query in the database will get the old data before the update and put the old data into the cache, thereby causing the inconsistency between the cache and the database data.

The terminal 101 and the router 1021 are connected through a wireless or wired network.

[0049] The router 1021 is configured to obtain a target operation instruction of target data from the data request of the terminal 101, and send the target operation instruction to a target queue in the message queue cluster 1022, the target data being attribute data of a target object displayed by the terminal, the target queue being configured to store a data operation instruction of the target data, the data operation instruction including a data reading instruction and a data updating instruction.

[0056] Of course, the request processing system provided in the embodiments of the present application can also be applied to other scenarios, which are not limited in the embodiments of the present application.

[0057] The embodiment of the present application provides a request processing system, which comprises a router, a message queue cluster, a service server cluster and a database. Figure 2 The embodiment of the present application provides an interactive flowchart of a request processing system for processing a request. Referring to Figure 2 The interactive flowchart of the request processing system is as follows:

[0058] 201. The router obtains a target operation instruction of target data from a data request of a terminal, and the target data is attribute data of a target object displayed by the terminal.

[0059] In the embodiment of the present application, the router is a hardware device connecting two or more networks, and functions as a gateway between the networks. The router can receive a data request sent by a terminal, and then parse a target operation instruction of target data from the data request. The terminal is a mobile phone, a desktop computer, a notebook computer, a tablet computer or the like. The target object is content displayed based on the terminal, which can be a webpage displayed by the terminal or a commodity in a shopping interface displayed by the terminal. The terminal sends a data request to the router in response to a processing operation of a user on the target data. The data request carries a target operation instruction of the target data, and the target operation instruction is a data operation instruction for instructing a server to process the target data.

[0060] In some embodiments, the target object can be a commodity, a webpage or a game character. When the target object is a commodity, the target data can be attribute data such as a price, a quantity or a size of the commodity; when the target object is a game character, the target data can be attribute data such as a blood volume, a skill or an appearance of the game character; and when the target object is a webpage, the target data can be attribute data such as an appearance or a type of the webpage.

[0061] 202. The router sends the target operation instruction to a target queue in the message queue cluster, and the target queue is used for storing a data operation instruction of the target data, and the data operation instruction comprises a data reading instruction and a data updating instruction.

[0062] In the embodiment of the present application, the router can send the parsed target operation instruction to a target queue in the message queue cluster. The message queue cluster comprises a plurality of message queues, and the target queue is a message queue used for storing a data operation instruction of the target data. In a data transmission process, the message queue is a container used for storing a data operation instruction of data.

[0063] In some embodiments, the router can send the target operation instruction of the target data to a corresponding message queue based on a data type of the target data. Accordingly, the router obtains the data type of the target data from the data request of the terminal, and performs the following step (1) in a case where the data type is a first data type; performs the following step (2) in a case where the data type is a second data type.

[0064] (1) In a case where the data type is the first data type, the router sends the target operation instruction to a first queue, the first data type represents a read-only attribute of the target object, and the first queue is used to store a data read instruction for the read-only attribute.

[0065] In the embodiments of the present application, the router first obtains the target operation instruction of the target data from the data request of the terminal, and then obtains the data type of the target data by analyzing the data request. In a case where the data type is the first data type, the router sends the target operation instruction of the target data to a first queue, and the first queue is the target queue. Since the first data type represents the read-only attribute of the target object, in a case where the data type of the target data is the first data type, the target operation instruction is a data read instruction, and is not a data update instruction.

[0066] (2) In a case where the data type is the second data type, the router sends the target operation instruction of the target data carried in the data request to a second queue, the second data type represents an editable attribute of the target object, and the second queue is used to store a data operation instruction for the editable attribute.

[0067] In the embodiments of the present application, the router first obtains the target operation instruction of the target data from the data request of the terminal, and then obtains the data type of the target data by analyzing the data request. In a case where the data type is the second data type, the router sends the target operation instruction of the target data to a second queue, and the second queue is the target queue. Since the second data type represents the editable attribute of the target object, in a case where the data type of the target data is the second data type, the target operation instruction can be a data read instruction or a data update instruction.

[0068] In some embodiments, the attribute data of the target object is affected by the attribute data of other objects, and the router can send the target operation instruction to a corresponding message queue by determining a related object associated with the target object, and the attributes of the related object and the target object affect each other. Accordingly, in a case where the target operation instruction is a data update instruction, the router determines a related object associated with the target object; and sends the target operation instruction to a third queue, and the third queue is used to store a data operation instruction for the attribute data of the related object.

[0069] In the method, the router first acquires the target operation instruction of the target data from the data request of the terminal. In a case where the target operation instruction is a data update instruction, the router determines a message queue for storing a data operation instruction of attribute data of a related object associated with the target object, i.e., a third queue, which is the target queue. The router sends the target operation instruction of the target data to the third queue. Since the attribute of the related object and the attribute of the target object influence each other, in a case where the target operation instruction of the attribute data of the target object is a data update instruction, i.e., the attribute data of the target object is changed, the attribute data of the related object will be influenced by the attribute data of the target object and will also be changed accordingly. By sending the target operation instruction to the third queue for storing the data operation instruction of the attribute data of the related object, it can be ensured that the attribute data of the related object associated with the target object is changed accordingly when the attribute data of the target object is changed. Correspondingly, in a case where the target operation instruction is a data read instruction, since the attribute data of the target object is not updated, the target operation instruction can be sent to the message queue corresponding to the target object or can be sent to the third queue.

[0070] In some embodiments, the router can send the target operation instruction to the target queue corresponding to the object identifier based on the object identifier of the target object. Correspondingly, the router acquires the object identifier of the target object from the data request of the terminal, and sends the target operation instruction to the target queue corresponding to the object identifier. In the embodiments of the present application, the router first acquires the target operation instruction of the target data from the data request of the terminal. Since the target data is the attribute data of the target object displayed by the terminal, based on the data request, the router can also acquire the object identifier of the target object. Then the router sends the target operation instruction of the attribute data of the target object to the target queue corresponding to the object identifier. The object identifier of the target object includes various types of identifiers. For example, when the object identifier of the target object is a page identifier, the page identifier is used to indicate the web page to which the target object belongs; when the object identifier of the target object is a commodity identifier, the commodity identifier is used to indicate the type of commodity to which the target object belongs; when the object identifier of the target object is a game object identifier, the game object identifier is used to indicate the type of game object to which the target object belongs.

[0071] 203、The message queue cluster sends the target operation instruction in the target queue to a target service server, and the target service server is a service server associated with the target queue in the service server cluster.

[0072] In the embodiments of the present application, the service server cluster includes a plurality of service servers. The service server is associated with a message queue, and the service server is configured to process data based on data operation instructions in the message queue. Since the target service server is associated with the target queue, the message queue cluster can sequentially send data operation instructions in the target queue to the target service server associated with the target queue. The target service server is configured to process target data based on the received data operation instructions.

[0073] In some embodiments, when the target operation instruction is inserted into the target queue, the message queue cluster can also deduplicate data operation instructions in the target queue. Correspondingly, in the case where the target operation instruction is a data read instruction, the message queue cluster performs step (1); in the case where the target operation instruction is a data update instruction, the message queue cluster performs step (2).

[0074] (1) In the case where there is a duplicate operation instruction that duplicates the target operation instruction in the target queue, and there is a data update instruction between the target operation instruction and the duplicate operation instruction, the message queue cluster removes the duplicate operation instruction from the target queue; in the case where there is no data update instruction between the target operation instruction and the duplicate operation instruction, the message queue cluster removes the target operation instruction from the target queue.

[0075] Wherein, after the router sends the target operation instruction of the target data to the target queue, since the target queue stores a plurality of data operation instructions, in the case where the plurality of data operation instructions are the same data operation instruction, in order to speed up the processing speed of the target service server, the message queue cluster can deduplicate the data operation instructions in the target queue. Therefore, in the case where the target operation instruction is a data read instruction, and there is a duplicate operation instruction that duplicates the target operation instruction in the target queue, since the insertion time of the duplicate operation instruction is earlier than that of the target operation instruction, the message queue cluster can deduplicate in different ways according to different situations. Mode one, in the case where there is a data update instruction between the target operation instruction and the duplicate operation instruction, the message queue cluster can remove the duplicate operation instruction from the target queue, so that the target service server can ensure that the target service server obtains the execution result of the target operation instruction from the cache or the database of the most recently updated database when executing the target operation instruction. Mode two, in the case where there is no data update instruction between the target operation instruction and the duplicate operation instruction, the target operation instruction is removed from the target queue. Since the execution results of these data read instructions are the same, in order to reduce the storage burden of the message queue cluster, the target operation instruction is removed from the target queue.

[0076] (2) In the case that there is a repeated operation instruction duplicated with the target operation instruction in the target queue, the message queue cluster removes the target operation instruction from the target queue.

[0077] In the case that the target operation instruction is a data update instruction and there is a repeated operation instruction duplicated with the target operation instruction in the target queue, since the insertion time of the repeated operation instruction is earlier than that of the target operation instruction, after the repeated operation instruction is executed, the target operation instruction does not need to be executed again, that is, the target operation instruction is a redundant data operation instruction, and thus the message queue cluster can remove the target operation instruction from the target queue. In this case, a plurality of repeated data update instructions are arranged together, and since the execution results of these data update instructions are the same, in order to reduce the storage burden of the message queue cluster, the target operation instruction is removed from the target queue.

[0078] It should be noted that, taking the data update instruction as an example, the data update instructions sent by the same terminal for the same data are repeated data operation instructions, and the data update instructions sent by different terminals for the same data are not repeated data operation instructions. The same applies to the data read instruction, which is not described here.

[0079] In some embodiments, in order to avoid the loss of data operation instructions in the message queue in the case of message queue exception, the message queue cluster can perform persistent processing on the data operation instructions in the target queue. Correspondingly, in response to the update of the data operation instructions in the target queue, the message queue cluster performs persistent processing on the data operation instructions of the updated target queue.

[0080] In the case that the message queue appears an exception, the message queue cluster can also obtain the lost data operation instruction by replaying the data operation instruction in the target queue. Alternatively, the message queue cluster can use a third-party middleware to perform persistent processing on the data operation instruction in the target queue. For example, redis (remote dictionary server), rabbitmq (a message queue service software), kafka (a subscription message system), and the like all implement good persistent mechanisms. Among them, the kafka message queue naturally supports zero-copy of messages and disk sequential read-write mechanism, and the data processing capacity can reach tens of millions, greatly improving the data processing capacity. The high performance and high reliability of the request are guaranteed.

[0081] It should be noted that the embodiments of the present application take the target operation instruction inserting the target queue as an example to illustrate the de-duplication, optionally, the message queue cluster can de-duplicate any message queue when a data operation instruction is added to the message queue, or the message queue cluster can de-duplicate each message queue every certain period of time, and the embodiments of the present application do not limit this.

[0082] 204. The target service server obtains an execution result of the target operation instruction from the cache of the database or the database based on the target operation instruction.

[0083] In the embodiments of the present application, since the data operation instruction includes the data read instruction and the data update instruction, the target service server obtains the execution result of the target operation instruction from the cache of the database or the database based on different target operation instructions. In the case that the target operation instruction is the data update instruction, the target service server deletes the target data from the cache of the database in response to the data update instruction, updates the target data in the database to obtain updated target data, and stores the updated target data into the cache of the database. In the case that the target operation instruction is the data read instruction, the target service server can read the target data from the cache of the database based on the data read instruction. In the case that the cache of the database includes the target data, the target service server returns the target data to the router; in the case that the cache of the database does not include the target data, the target service server reads the target data from the database and puts the target data into the cache.

[0084] In some embodiments, the router associates the service server with at least one message queue based on the state information of the service server, and the state information is used to indicate the working state of the service server. Accordingly, for any service server, the router determines the weight of the service server based on the state information of the service server. The router determines at least one message queue associated with the service server from the message queue cluster based on the weight of the service server. By associating the service server with the message queue based on the weight, the message queue can be reasonably distributed according to the service processing capacity of the service server, the computing resources of the service server can be fully utilized, and the service processing efficiency can be improved.

[0085] In the embodiments of the present application, since the configurations of the service servers in the service server cluster can not be consistent, some service servers have high configurations and can process data operation instructions of the message queues at high speed, and some service servers have low configurations and can process data operation instructions of the message queues at low speed. Therefore, it is not a good processing manner to equally distribute the message queues to the service servers. The router can determine the weight of the service server based on the state information of the service server, and the weight can reflect the service processing capability of the service server, that is, the number of the message queues that can be processed by the service server. Based on the weight, the router can select at least one message queue from the message queue cluster and associate the at least one message queue with the service server. The weight of the service server is positively correlated with the number of the message queues associated with the service server, that is, the greater the weight, the greater the number of the message queues associated with the service server; and the smaller the weight, the smaller the number of the message queues associated with the service server.

[0086] In some embodiments, in the case that the state information of the service server changes, the router updates the message queues associated with the service server. Correspondingly, the router determines the time interval at which the service server updates the state information based on the service type of the service server; acquires the state information of the service server every time interval; and updates the message queues associated with the service server in response to the change of the state information of the service server.

[0087] Since the working state of the service server is not always unchanged, in the case that the state information of the service server changes, the service server cluster needs to regularly report the state information of the service server, so that the router can monitor the working state of the service server in real time. The time interval at which the state information of the service server is reported is not limited. The router can determine the time interval at which the service server updates the state information based on the service type of the service server, and acquire the state information of the service server every time interval. When the state information of the service server changes, the router updates the weight of the service server based on the changed state information. The router updates the message queues associated with the service server based on the updated weight. This enables the router to acquire the latest state information of the service server, and update the message queues associated with the service server when the state information changes, thereby avoiding congestion of the message queues and improving the service processing efficiency.

[0088] In some embodiments, the number of the service servers in the service server cluster can be dynamically expanded or scaled in different cases. Correspondingly, in the case that the service server cluster is expanded, the router performs the following step (1); and in the case that the service server cluster is scaled, the router and the service server cluster perform the following step (2).

[0089] (1) In a case where a first service server in idle is added to the service server cluster, the router determines at least one second service server in the first state from the service server cluster, the first state being used to indicate that the load of the service server is greater than the load threshold; determines at least one message queue associated with the at least one second service server; and associates the at least one message queue with the first service server.

[0090] In the embodiment of the present application, in a case where a first service server in idle is added to the service server cluster, the router can obtain the state information of the service server every time interval, so that the real-time state information of the service server cluster can be obtained. When the router obtains that the first service server in the service server cluster is in idle, at least one second service server in the first state can be determined from the service server cluster. The first state is used to indicate that the load of the service server is greater than the load threshold. The router can assign at least one message queue associated with the second service server to the first service server, that is, associate the at least one message queue associated with the second service server with the first service server.

[0091] (2) In a case where the state of a third service server in the service server cluster is unavailable, the service server cluster removes the third service server from the service server cluster; and the router assigns at least one message queue associated with the third service server to other service servers in the service server cluster, the third service server being any service server.

[0092] In the embodiment of the present application, in a case where the state of a third service server in the service server cluster is unavailable, the service server cluster removes the third service server. When the router obtains that the state of the third service server is unavailable, at least one message queue associated with the third service server is assigned to other service servers in the service server cluster. That is, the message queue associated with the third service server is reassigned.

[0093] 205. The target service server returns the execution result of the target operation instruction to the router.

[0094] In the embodiment of the present application, after the target service server obtains the execution result of the target operation instruction, the target service server can directly return the execution result of the target operation instruction to the router, and the router forwards the execution result. The target service server can also return the execution result of the target operation instruction to the router through the message queue, so as to avoid that the router simultaneously receives too many execution results and causes downtime.

[0095] 206. The router sends the execution result to the terminal, which then displays the result based on the target object.

[0096] In this embodiment, the router receives the execution result of the target operation instruction sent by the target service server and sends the execution result to the terminal. The terminal can then display the execution result based on the target object.

[0097] For example: if the target object is a product and the target operation instruction is to update the inventory quantity or the discounted price, the terminal can display the inventory quantity of the product or the discounted price of the product; if the target object is a game character and the target operation instruction is to update the remaining health or skills, the terminal can display the remaining health of the game character or the skills of the character after upgrading.

[0098] This application provides a request processing system comprising a router, a message queue cluster, multiple service servers, and a database. The router sends target operation instructions from acquired target data to a target queue in the message queue cluster. The message queue cluster then sends the target operation instructions from the target queue to the service servers associated with that target queue. This allows the service servers to execute each data operation instruction sequentially when multiple data operation instructions are concurrently executed on any given data. The service servers retrieve the execution results from the cache or database and return them to the router, which then distributes them to the terminals. Since the next data operation instruction is not sent to the service server until the previous one has been completed, this avoids inconsistencies between the cache and the database caused by executing data read instructions in parallel before data update instructions have been completed, thus preventing the inconsistency between the cache and the database.

[0099] This application also provides a schematic diagram of a request processing system, such as... Figure 3 As shown, the request processing system includes a router, a message queue cluster, and a service server cluster. The router obtains data operation instructions for the target data from the terminal's data request and sends these instructions to a message queue in the message queue cluster. The message queue cluster then sends the data operation instructions from its message queue to the service server associated with that message queue. The service server can execute each data operation instruction sequentially. The service server cluster can also report the status information of the service servers to the router. Based on this status information, the router determines at least one message queue associated with each service server.
