First, the terminology involved in one or more embodiments of the present specification is explained.

IM, refers to instant messaging (Instant Messaging), IM service is to provide instant messaging services.

Social relationship: mainly refers to friend relationship, group relationship.

With the continuous development of instant messaging, more and more applications have added the IM function. A very important function point in the IM function is the synchronization and management of social relations. Due to the presence of many influencing factors such as network traffic and uncertain signal quality on the client side, it is difficult to synchronize and manage social relationships.

Based on this, an embodiment of this specification provides a data synchronization method, which is applied to a server, and generates a target data version number by collecting social change data of a first user, and updating the data version number corresponding to the social change data. Collect the data version number corresponding to the social data associated with the social change data of the second user, compare the data version number corresponding to the social data with the target data version number, and in the case of inconsistent comparison, The target data version number and the social change data are synchronized to the second user as incremental data.

Specifically, by setting a data version number for the user's social data, and by comparing the data version number corresponding to the first user's social data in the server with the data version number corresponding to the second user's social data of the same category, there is In the case of comparing inconsistent data version numbers, the social data corresponding to the inconsistent data version numbers in the social data of the first user can be synchronized to the second user, which can take into account the network traffic and ensure that different The consistency of social data among users, the correctness of social relations, and the timeliness of social data updates.

In this specification, a data synchronization method is provided, and this specification also relates to a data synchronization apparatus, a computing device, and a computer-readable storage medium, which will be described in detail in the following embodiments.

FIG. 1 shows a processing flow chart of a data synchronization method provided according to an embodiment of the present specification, including steps 102 to 108 .

Step 102: Collect social change data of the first user, update the data version number corresponding to the social change data, and generate a target data version number.

Specifically, the data synchronization method provided in the embodiment of this specification is applied to the server. Since the social relationship of the user is usually complicated, in order to ensure the social data of the first user stored in the user terminals of other users who have a social relationship with the first user If it is consistent with the real social data of the first user, the server needs to collect the social change data of the first user, and synchronize the change data to the relevant second user.

The social data described in the embodiments of this specification includes but is not limited to the user name, user avatar, user profile, and group data that the user joins in the user's social application; the social change data may include Modified and changed social data, as well as the modification time of social data and other information.

In addition, in the embodiment of this specification, the user name, user avatar, user profile, and group data that the user joins included in the social data correspond to different data categories, that is, the user name corresponds to data category 1, and the user avatar corresponds to Data category 2 and user profile correspond to data category 3, etc. The social data of each data category corresponds to an initial data version number.

After collecting the social change data of the first user, that is, the modified and changed social data, the server can set a data version number for the social change data, specifically, update the version number corresponding to the social change data ( The initial data version number corresponding to the data category of the social change data is updated), and the target data version number is generated. The update of the initial data version number can be used to indicate that the social data of the user has changed, and the social change data After synchronizing to the relevant second user, the target data version number can be used as the initial data version number, so that when the user modifies the social change data, the aforementioned data version number corresponding to the social change data is executed. process of updating.

For example, the first user modifies the user name. Before the modification, the user name of the first user is U10, and the corresponding initial data version number is V10. After the modification, the user name of the first user is U11, and the corresponding data version number is Can be updated to V11. After the user name U11 is synchronized to the relevant second user, V11 can be used as the initial data version number of the data category corresponding to the user name.

During specific implementation, the data version number corresponding to the social change data is updated, that is, the change time corresponding to the social change data is determined, and the data version number is updated based on the change time.

Specifically, in the embodiment of this specification, the change time (modification time) of the social change data may be used to update the data version number corresponding to the social change data, and specifically, the change time may be used as the target data version number corresponding to the social change data , wherein the change time can be obtained from the social change data.

Alternatively, a target algorithm (such as a hash algorithm) may also be used to process the social data, and the processing result may be used as the initial data version number of the social data, and the target algorithm may be used to process the social change data to generate The target data version number corresponding to the social change data.

Step 104: Collect the data version number of the second user corresponding to the social data associated with the social change data.

Specifically, after collecting the social change data of the first user, a second user associated with the social change data to be synchronized may be determined. For example, if the collected social change data is that the user name is changed to U11, it is determined that the second user associated with the social change data to be synchronized is all users who have social relations with the first user (the first user All friends and all groups joined by the first user); if the collected social change data is that the user joins the group G1, then it is determined that the second user associated with the social change data to be synchronized is the group Other users in G1 except the first user.

After the second user is determined, the data version number corresponding to the social data associated with the social change data of the second user can be collected. After a certain social data of the user is changed, in order to reduce the workload and resource consumption of the server, in practical applications, only the social data associated with the social change data in the social data of the second user can be selected to be updated, that is, the collection The data version number of the second user corresponding to the social data associated with the social change data, and the data version number is compared with the target data version number to determine whether the social data of the second user needs to be updated.

Following the above example, the first user modifies the user name, after the modification, the user name of the first user is U11, and the corresponding data version number is updated to V11. Then, the data version number of the second user corresponding to the social data associated with the social change data may be collected, specifically collecting the user name of the first user stored in the user terminal of the second user, and collecting the first user's username. A data version number corresponding to the user name of a user, so as to compare the data version number with the update result V11 of the aforementioned data version number to determine whether it is necessary to update the first user stored in the user terminal of the second user user name to update.

Step 106: Compare the data version number corresponding to the social data with the target data version number.

Specifically, as described above, the data version number corresponding to the social change data of the first user is updated, the target data version number is generated, and the data corresponding to the social data associated with the social change data of the second user is collected and obtained After the version number is obtained, the data version number can be compared with the target data version number corresponding to the social data of the same category to determine whether the social data of the second user needs to be updated.

Step 108, in the case of inconsistent comparison, synchronize the target data version number and the social change data to the second user as incremental data.

Specifically, the data version number and the target data version number are compared to obtain a corresponding comparison result. If it is determined that the comparison between the two is inconsistent according to the comparison result, the social change data of the first user and the social change data are corresponding The version number of the target data is synchronized to the second user as incremental data; if it is determined according to the comparison result that the two are consistent, there is no need to synchronize the social change data to the second user.

During specific implementation, the server can synchronize social change data to the second user through a persistent connection. Therefore, the synchronization of the target data version number and the social change data as incremental data to the second user is specifically: establishing a long connection with the user terminal of the second user, and synchronizing the target data version number and the social change data to the user terminal through the long connection, so that the target data version number and the social The change data is synchronized to the second user as incremental data, so that the social data of the first user stored in the user terminal of the second user is consistent with the actual social data of the first user.

In the foregoing embodiment, a data version number is set for the user's social data, and the data version number corresponding to the social change data of the first user in the server is compared with the data version number corresponding to the social data of the second user of the same category. way to determine whether social change data needs to be synchronized with the second user to ensure the consistency of social data among different users, the correctness of social relationships, and the timeliness of social data updates.

In the embodiment provided in this specification, the server can also receive a data modification instruction submitted by the first user for the social data to be modified, update the social data to be modified according to the data modification information carried in the data modification instruction, and update the social data to be modified. The update result of the data to be modified is synchronized to the second user.

Specifically, when the first user needs to modify his social data such as user name, user avatar, user profile and other social data in the social application, he can send a data modification instruction to the server, and the data carried in the data modification instruction is to modify the data. The information may specifically include the social data to be modified and the data modification result of the social data to be modified; the server can update the social data to be modified of the first user according to the data modification information, and synchronize the update result to the second user. User, that is, the server actively synchronizes the social change data of the first user to the second user.

Further, after updating the social data to be modified according to the data modification information carried in the data modification instruction, the method further includes: updating the first social data of the first user based on the update result of the social data to be modified. The corresponding data version number is updated to generate a first data version number corresponding to the first social data of the first user.

Further, after generating the first data version number corresponding to the first social data of the first user, the method further includes: determining at least one second user who has a social relationship with the first user; obtaining the at least one first user. The second social sub-data associated with the first user in the second social data of the two users, and the second data sub-version number corresponding to the second social sub-data is determined; A first social sub-data in social data that has an associated relationship with the second social sub-data, and a first data sub-version number corresponding to the first social sub-data is determined; the first data sub-version number is combined with The second data sub-version number is compared; in the case of inconsistent comparison, the first data sub-version number and the first social sub-data corresponding to the first data sub-version number are synchronized as incremental data to the second user.

Specifically, in the foregoing embodiment, the server compares the target data version number corresponding to the social change data of the first user with the data version number corresponding to the social data associated with the social change data in the social data of the second user to determine whether the social change data needs to be synchronized to the second user.

However, in the embodiment of this specification, the server chooses to actively synchronize the social change data of the first user to the second user who has a social relationship with the first user. In this synchronization process, there may be network or other reasons. When data synchronization fails.

Therefore, after updating the social data of the first user to be modified, the server can update the data version number corresponding to the first social data of the first user based on the update result, and generate a corresponding version of the first social data of the first user. Specifically, based on the update result, the data version number corresponding to the social change data in the first social data of the first user is updated, and the update result of the data version number is removed from the first social data. The data version numbers corresponding to other social data other than the social change data together form a first data version number corresponding to the first social data of the first user.

Next, the server may determine a second user (a friend of the first user, or in the same group as the first user, etc.) who has a social relationship with the first user, and obtain the relationship between the second user and the first user. The social data (second social sub-data, for example, the user name, user avatar, user profile and other information of the first user stored in the user terminal of the second user), and determine that these social data correspond to the data version numbers (No. 2 data subversion number).

Then determine the first social sub-data that is associated with the second social sub-data in the first social data of the first user, and determine the first data sub-version number corresponding to the first social sub-data; if The second social sub-data is the user name, user avatar, and user profile of the first user stored in the user terminal of the second user, and the first social sub-data is the first social sub-data stored in the user terminal of the first user. A user's user name, user avatar, and user profile, after determining the first social sub-data and the first data sub-version number corresponding to the first social sub-data, and comparing the first data sub-version number with the same category The second data sub-version number corresponding to the second social sub-data is compared, and in the case of inconsistent comparison, the first data sub-version number and the first social sub-version number corresponding to the first data sub-version number are compared. The data is synchronized to the second user as incremental data.

In addition, the premise that the server can successfully synchronize data to the second user is that the account of the social application of the second user is in a logged-in state (online). The login status of the second user can be specifically implemented by: determining at least one second user that has a social relationship with the first user; detecting the first login status of the at least one second user; The first login status of the two users is logged in, and if the comparison is inconsistent, the target data version number and the social change data are synchronized to the second user as incremental data.

Further, if the login status of the at least one second user is not logged in, in the case of inconsistent comparison, the target data version number and the social change data are stored as incremental data; The second login status of at least one second user; if the second login status of the at least one second user is logged in, the incremental data is synchronized to the second user.

Specifically, after comparing the data version number corresponding to the social data with the target data version number, it is necessary to determine a second user who has a social relationship with the first user, and detect the login status of the second user; Wherein, if the login status of the second user is logged in (online), it can be determined whether data synchronization needs to be performed with the second user according to the comparison result, and if data synchronization is required, the social change data is synchronized to The second user is sufficient; if the login status of the second user is not logged in (offline), in this case, it is also necessary to determine whether data synchronization needs to be performed with the second user according to the comparison result. Then the social change data needs to be stored.

As mentioned above, the social data may be processed using a target algorithm (eg, a hash algorithm), and the processing result may be used as an initial data version number of the social data, and the social change data may be processed using the target algorithm , and generate the target data version number corresponding to the social change data; or, the change time of the social change data may be used as the target data version number corresponding to the social change data.

Therefore, if a target algorithm (such as a hash algorithm) is used to generate the data version numbers of social data and social change data, only when the social change data and social data are completely consistent, the target algorithm (such as a hash algorithm) is used to compare the two The hash value (initial data version number and target data version number) generated by processing by the user will be consistent; or, if the change time of social data or social change data is used as the data version number, only the social change Only when the data and social data are changed at the same time will the comparison be consistent.

If the comparison is inconsistent, it means that the social data associated with the social change data of the second user is inconsistent with the social change data of the first user, and data synchronization needs to be performed, that is, the social change data needs to be synchronized to the second user. user.

In practical applications, if the login status of the second user is logged in (online), in the case of inconsistent comparison, the social change data and the version number of the target data are directly synchronized to the second user; If the user's login status is not logged in (offline), if the comparison is inconsistent, the social change data and the version number of the target data need to be stored, and continue to detect the login status of the second user. The next time the user logs in, the stored social change data is synchronized to the second user.

In addition, after it is determined that the login status of the second user is not logged in, and the data version number is inconsistent, the target data version number and the social change data are stored as incremental data, and the detection is continued. For the login status of the at least one second user, after detecting that the second user is logged in, the data volume of the stored incremental data can be detected; if the data volume of the incremental data is greater than the preset data volume threshold, sending a data synchronization instruction to the at least one second user; and synchronizing the incremental data to the at least one second user in response to a data synchronization request sent by the at least one second user.

Specifically, the server can send the social change data to the second user through a persistent connection, but when the second user is not logged in, the server needs to store the social change data, and when the second user goes online again After that, the stored social change data is synchronized to the second user; however, when the data volume of the social change data stored by the server is greater than the preset data volume threshold, in order to reduce the data transmission pressure on the server, the server can send the data to the second user. The second user sends a data synchronization instruction, and the second user actively pulls the social change data from the server.

In addition, after comparing the data version number corresponding to the social data with the target data version number, the synchronization of the social change data may also be determined by determining the data change frequency of the first social data of the first user Specifically, it can be implemented in the following ways: determining the data change frequency of the first social data of the first user; if the data change frequency is greater than a preset change frequency threshold, then the target data version number and the social The change data is stored as incremental data; when it is detected that the data volume of the incremental data is greater than the preset data volume threshold, determine at least one second user who has a social relationship with the first user, and report to all The at least one second user sends a data synchronization instruction; and in response to a data synchronization request sent by the at least one second user, the incremental data is synchronized to the at least one second user.

Specifically, the server can send the social change data to the second user through a long connection, but if the data change frequency of the first social data of the first user is higher than the preset threshold, if the server uses the long connection in batches Sending social change data to the second user has the defect of low data synchronization efficiency. Therefore, in the case where the data change frequency of the first social data of the first user is higher than the preset threshold, the server can choose to send the social change data Store it, and when the stored social change data reaches the preset data volume threshold, synchronize the stored social change data to the second user; or issue a pull instruction for the social change data to the second user. The second user does a full pull of social change data to achieve data synchronization.

In the embodiment of this specification, when a user's social data changes, such as the addition of friends, the modification of friends' nicknames, the change of group members, etc., the server will incrementally push the changed data to other users through a long connection. To ensure the synchronization of social data of different users. In addition, the combination of incremental data synchronization by the server and data pulling by the user is beneficial to ensure the correctness and timeliness of the data synchronization results, and is beneficial to reduce the data transmission pressure on the server.

The data synchronization method is further described below by taking the application of the data synchronization method provided in this specification in a social scene as an example with reference to FIG. 2 . 2 shows an interactive schematic diagram of a data synchronization process provided by an embodiment of the present specification, and the specific steps include steps 202 to 228 .

Step 204: The server updates the social data to be modified according to the data modification information carried in the data modification instruction, and updates the data version number corresponding to the social data to be modified based on the update result of the social data to be modified.

Step 206, the server synchronizes the update result of the data to be modified and the update result of the data version number to the second client.

Step 208, the second client stores the update result of the data to be modified and the update result of the data version number.

Step 210: The server collects the social change data of the first client, and updates the data version number corresponding to the social change data to generate a target data version number.

Step 212 , the server collects the data version number corresponding to the social data associated with the social change data of the second client.

Two users send data synchronization instructions.

Step 224, the server receives the data synchronization request sent by the second client.
