Description

Data update method, device, server and storage medium

Technical field

The present invention relates to the field of network technology, and in particular to a data update method, device, server and storage medium.

Background technique

With the development of network technology, more and more applications can provide users with various data services. For example, when users use live broadcast applications and may need to obtain live broadcast information such as event lists, they can pull the event list from the server. . Of course, you can also pull data such as friend relationship chains, record lists, etc. based on different usage requirements. These data are usually large and complex data packets that are not updated frequently. If they are re-pulled every time, a large amount of useless traffic will be wasted.

In order to save traffic, the general approach is to perform a hash operation on these data packets and send the calculated hash value to the client. When the client pulls it, it first determines the hash value in the client request and the server Whether the saved hash values are the same, if so, it means that the data has not been updated since the last pull, so the server does not need to return duplicate data, saving the traffic of this request.

However, the above approach reduces the traffic consumed by repeated updates to a certain extent, but there are still some shortcomings. When the data only undergoes partial or minor changes, such as adding or removing a friend in the friend relationship chain, such partial or minor changes will also cause the hash value of the entire data to change, causing the server to still determine that it needs to be re-issued. The entire data, that is, most of the other identical data will be distributed repeatedly, causing a lot of waste of traffic.

Figure 1 shows a structural block diagram of an application service system 100 provided by an exemplary embodiment of the present application. The application service system 100 includes: a terminal 110 and an application service platform 140.

The terminal 110 is connected to the application service platform 110 through a wireless network or a wired network. The terminal 110 may be at least one of a smart phone, a game console, a desktop computer, a tablet computer, an e-book reader, an MP3 player, an MP4 player, and a laptop computer.

The terminal 110 is connected to the application service platform 140 through a wireless network or a wired network.

The application service platform 140 includes at least one of a server, multiple servers, a cloud computing platform, and a virtualization center. Optionally, the application service platform 140 includes: a logical server, a record database, and a content database. The logical server is used to provide the terminal 110 with request processing services. There can be one or more logical servers. When there are multiple logical servers, there are at least two logical servers used to provide different services, and/or there are at least two logical servers used to provide the same service, such as providing the same service in a load balancing manner. This application The examples are not limiting.

Those skilled in the art will know that the number of the above terminals may be more or less. For example, there may be only one terminal, or there may be dozens, hundreds, or more terminals. In this case, the application service system may also include other terminals. The embodiments of this application do not limit the number of terminals and device types.

Figure 2 is a flow chart of a data update method provided by an embodiment of the present invention. Referring to Figure 2, the interaction between the terminal, the logical server, the recording server and the content server is used as an example to illustrate. This process may specifically include the terminal requesting data from the logical server, and incremental data based on the request between the logical server and the recording database. Of course, in order to achieve the above incremental data acquisition, for the content database, it also needs to involve the process of notifying the recording database when the data changes. Next, the interactive process of the embodiment of the present invention will be described in detail with reference to the processes shown in FIG. 2 and FIG. 3 .

301. The terminal sends a data acquisition request to the logical server. The data acquisition request carries a first characteristic value. The first characteristic value is a characteristic value of the target object that has been stored by the terminal.

For the terminal, the data acquisition request for the target object can be triggered periodically or when the web page where the target object is located is updated. When the terminal triggers the data acquisition process, the first data acquisition request can be obtained from the data stored in the terminal. The characteristic value, that is, the characteristic value of the target object, is sent by carrying the first characteristic value in the data acquisition request.

During any update process of the target object, the terminal can obtain the characteristic value used to represent the current data content of the target object. The characteristic value can be obtained by the terminal through the logical server during the update process, or it can be obtained during the update process. After the data is updated, it is generated based on the locally updated data of the terminal, which is not limited in the embodiment of the present invention.

Among them, the target object can be any object, for example, a certain list data, a certain common scene data, a certain common page, etc. That is, when the terminal receives any list loading instruction, it obtains the list identifier and the list Hash value, carry the list ID and list hash value in the data acquisition request, and the process is the same in other cases. The feature value can be a hash value of the data, used to uniquely identify the data content of the data. It can be understood that different feature values mean different data contents. Therefore, comparison between feature values can determine whether the data content has occurred. Variety.

In some embodiments, when sending a data acquisition request, the terminal can also carry the timestamp or version number of the last data update to identify the time or version of the last update. Of course, the version number can also be represented by a timestamp. Form, the embodiment of the present invention does not limit this.

It should be noted that the logical server can pre-set a target list to store objects that can match characteristic values. When receiving a data acquisition request, the logical server can detect the target object of the data acquisition request; when the target object When the target object exists in the target list, the step of matching in at least one second feature value of the server according to the first feature value is performed; when the target object does not exist in the target list, the first feature value is matched The third characteristic value is matched with the characteristic value of the target object currently stored on the server.

302. After receiving the data acquisition request, the logical server sends a matching request to the record database, where the matching request carries the first characteristic value.

The record database is used to record data change operations in the content database, generate corresponding feature values based on the data after the data change operation, and maintain the correspondence between data change operations and feature values. Of course, for each target object, the record database can maintain corresponding data for each target object according to the object identifier. Therefore, the logical server can initiate a matching process to the record database based on the received data retrieval request in order to determine which data of the target object has changed.

In the embodiment of the present invention, the logic server is mainly responsible for processing the received request, and distributes the data acquisition task corresponding to the request to the corresponding database for processing by matching the request, thereby avoiding the problems caused by a single server implementing various functions. In the event of excessive load, the normal and stable operation of the entire system can be guaranteed.

303. After receiving the matching request, the record database performs matching in at least one second characteristic value according to the first characteristic value to determine the target second characteristic value. The second characteristic value is the target object in at least one data. After the change operation, the characteristic value is the second characteristic value of the target that successfully matches the first characteristic value.

When receiving a matching request, the record database can determine at least one second characteristic value corresponding to the object identifier based on the object identifier of the target object carried in the matching request, and then based on the at least one second characteristic value and the object identifier carried in the matching request. The first feature value is matched to determine the second feature value that matches successfully.

In a possible implementation, the matching process may include: according to the first feature value, matching the at least one second feature value in order from front to back in generation time. When the first feature value matches any of the second feature values, If a second feature value is the same, it is determined that the match is successful. The generation time refers to the generation time of the second feature value. For any second feature value, it is generated according to the data change operation that occurs in the content database. Therefore, its generation time can represent the time between data content. The time of change can be matched in order from front to back of the generation time, which can make the matching process more orderly and avoid confusing matching.

In some embodiments, when matching in order from front to back of generation time, the efficiency of matching can also be improved based on the generation time of the first feature value, that is, based on the first feature value, the third feature value is determined. The generation time of a feature value; according to the generation time of the first feature value, among the second feature values whose generation time is later than the generation time of the first feature value in the at least one second feature value, according to the generation time from before to Matching is performed in the following order. Among them, the generation time of the first characteristic value can represent the update time of the data content updated by the terminal in the server. Therefore, it also means that the data of the target object stored by the terminal has been updated to the generation time. Then, at the generation time For this terminal, the previous data is data that has been updated, so there is no need to match this part of the data. It is only necessary to compare the second feature value whose generation time is later than the generation time of the first feature value, which greatly reduces Reduces the amount of matching calculations and improves matching efficiency.

In some embodiments, the data acquisition request can also carry a version number, and the matching request can also carry the version number. The record database side can determine the second characteristic value corresponding to the updated version after the version number, and then based on this The second feature values corresponding to the partially updated versions are matched to reduce the calculation amount of matching and improve the efficiency of matching.

304. The record database obtains at least one data change record corresponding to the second characteristic value of the target.

Among them, the data change record includes data change type and change data. For example, for a data modification operation, the data change type can be modification, and the change data can be modified data. For a data deletion operation, the data change type can be deletion. The changed data may be information about the data to be deleted, such as the data name, data identification, etc. of the data to be deleted. The data change record is generated based on any data change operation of the content database. Specifically, one data change record may correspond to at least one data change operation, which is not limited in the embodiment of the present invention.

In some embodiments, the record database may use a key-value database to store data change records. For example, as shown in Figure 4, for different objects, their respective data change records and hash values can be stored correspondingly.

305. The record database sends the at least one data change record to the logical server.

306. The logical server delivers at least one received data change record to the terminal.

In the above steps 305 to 306, after the recording database obtains the data change record, the data change record can be sent to the terminal through the logical server, so that the terminal can perform corresponding updates.

307. After receiving the at least one data change record, the terminal updates the target object stored in the terminal based on the at least one data change record.

After receiving the at least one data change record, the terminal can perform corresponding updates to the stored target object on the terminal based on the data change type and change data in the data change record. For example, when the data change type is a data modification operation When the data change type is a data deletion operation, the corresponding data in the stored target object is deleted.

In some embodiments, after performing corresponding updates, the terminal can generate feature values based on the updated target object and overwrite the original feature values with the newly generated feature values, so that the newly generated feature values can be applied the next time data acquisition is required. Feature values are obtained incrementally as shown in the above process.

In some embodiments, when the recording database sends at least one data change record, it can also send the target second characteristic value together, so that the terminal can receive at least one data change record and the target second characteristic value, and use the target second characteristic value. If the two eigenvalues cover the original eigenvalue, there is no need for the terminal to regenerate the eigenvalue, which reduces the calculation amount of the terminal.

The technical solution provided by the embodiment of the present invention matches the characteristic value carried by the data acquisition request with multiple characteristic values maintained based on the data change operation on the server when receiving a data acquisition request, thereby determining that the match is successful. The data change record corresponding to the characteristic value of Returning the incremental changes avoids wasting data traffic.

The above embodiment provides a process of how to update data for the terminal. In order to implement the above data update process, the recording database needs to record the data changes in the content database. The recording process will be described below. See Figure 5. The recording process can include:

501. When it is detected that any data change operation occurs on the target object in the content database, the content database sends a data change notification to the record database, and the data change notification carries the data change operation.

502. After receiving the data change notification, the record database generates a data change record based on the data change operation, and generates a second characteristic value based on the data change operation and the stored data content.

503. The record database stores the data change record of the target object in correspondence with the second characteristic value.

For any object, the data change record and the corresponding second characteristic value of the object can be stored in the operation sequence of the object. When the relevant data is changed in the content database, based on the above process, the record database will record the change. This ensures data consistency.

The above process of recording data change operations can be performed every time a data change operation occurs, or it can be performed based on a preset number of data change operations. When the recording database receives any data change notification, it can first obtain the data change operations, and Store the data change operations in the cache queue. When the cache queue is full, the data change operations stored in the cache queue will generate data change records to avoid too frequent data reading and writing.

The above embodiments can be applied to any application scenario, and the embodiments of the present invention do not limit this. In addition, it should be noted that the above embodiments can be applied to a system architecture including a record database, and in some embodiments, the record database can be used as a part of the content database. The embodiments of the present invention are specific to what kind of system they are applied to. The architecture is not specifically limited.

The embodiment of the present invention adds a record database to the system. For any object, the data change record and the corresponding second characteristic value of the object can be stored in the operation sequence of the object. When the relevant data is changed in the content database, Based on the above process, the recording database will record the change to ensure data consistency.
