Description

Technical Field

[0001] The present application relates to the technical field of user data management, and more specifically, to a method, device and electronic device for real-time synchronization of online relationships between users and friends in a high-concurrency scenario. Background Art

[0002] In social scenarios, when a user comes online, he needs to see the online status of his friends, and his online friends also need to know that the user is online, so that they can chat, make appointments to play, and interact with each other in other scenarios.

[0003] However, currently when querying the online list of a user's friends, the friend service is called first each time to obtain the user's friend list, and then the user's online center service is called to obtain the user's online status. If the user has a large number of friends, each friend needs to be verified once to see if they are online, which takes a long time.

[0004] In addition, when the user refreshes, the user's friend online list needs to be queried every time the user refreshes. If the number of users triggering the query is m, and the average number of friends is n, the number of friend list queries is n, and the number of user online status queries is m*n. The query data volume is too large, which may cause the service to crash and become unavailable.

[0005] Therefore, it is desired to provide a new real-time synchronization solution for user friend online relationships in high-concurrency scenarios. Summary of the invention

[0027] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0028] Exemplary Alignment Detection Methods

[0029] Figure 1 The present invention is a flowchart of a method for real-time synchronization of user friend online relationships in a high-concurrency scenario according to an embodiment of the present application.

[0030] like Figure 1 As shown, according to the method for real-time synchronization of user friend online relationships in a high-concurrency scenario according to an embodiment of the present application, the following steps are included.

[0031] Step S110, creating a user friend online center of the user, wherein the user friend online center has the user's friend online list. That is, in the embodiment of the present application, in order to solve the problem caused by the need to query the friend list and the online status of all friends every time a query is made, a user friend online center is created. In this way, in each query, the user's friend online list can be directly obtained through the user friend online center, and the friend list and the online status of all friends are no longer directly queried, and the online status of friends is maintained through the friend online center.

[0032] Step S120, when the user is online, the user friend online center receives a user online message from the user online center service and performs a user online operation to update the friend online list. Here, the user online center service is used to maintain the user's online status, so that the user can obtain information about whether the user is online from the user online center service, that is, receive a user online message.

[0033] As described above, in the embodiment of the present application, when a user goes online, the user's friend online center queries the friend online list. Specifically, the friend online list query logic of the user's friend online center is as follows:

[0034] 1. Query the online friend list, and return directly if found. That is, if the online friend list of the user already exists, it means that the user is already online, that is, it can be returned directly.

[0035] 2. If the friend online list is not found, the friend online list needs to be initialized. At this time, all query operations of the user are blocked and locked by adding a distributed lock to the user, waiting for the initialization of the friend online list to be completed. At this time, the friend online list can also be queried again to prevent the subsequent logic from being executed repeatedly concurrently.

[0036] 3. Obtain the user's friend list from the friend service. Here, the friend service is used to maintain the friend relationship between users, and query the user online center service through the friend list to obtain the friend online list and save it to the user friend online center.

[0037] 4. Release the distributed lock, end the above query logic and return the friend online list.

[0038] Therefore, in the real-time synchronization method of user friend online relationships in a high-concurrency scenario according to an embodiment of the present application, the user online operation includes a friend online list query operation, and the friend online list query operation includes: the user friend online center queries the friend online list; and, in response to querying the user online list, directly returns the friend online list.

[0039] Furthermore, in the above-mentioned method for real-time synchronization of user friend online relationships in a high-concurrency scenario, the friend online list query operation further includes: in response to not finding the user online list, adding a distributed lock through the user; obtaining the user friend list from the friend service, and querying the user online center through the user friend list to obtain the friend online list; saving the friend online list to the user friend online center; and, releasing the distributed lock and returning the friend online list.

[0040] In addition, in the embodiment of the present application, it is possible to determine whether the user is repeatedly online by obtaining the online frequency control parameter. If the user is repeatedly online in a short period of time, no operation is performed and the user's existing status is maintained. If the user is truly online again, the user's friend online list is obtained through the friend online list query logic as described above, and the friends in the user's friend online list are asynchronously notified that the user is online, thereby modifying the user's status in the friends list to online;

[0041] That is, in the real-time synchronization method of user friend online relationships in a concurrent scenario according to an embodiment of the present application, when a user is online, the user friend online center receives a user online message from a user online center service of a user application and performs a user online operation including: obtaining an online frequency control parameter to determine whether the user is repeatedly online; in response to the user being repeatedly online, not performing the user online operation and maintaining the user's existing status; in response to the user not being online again, obtaining the user's friend online list; and, asynchronously notifying the user's friend online list that the user is online, and modifying the user's status among friends to be online.

[0042] Step S130, when the user is offline, the user friend online center receives the user offline message from the user online center service and performs the user offline operation. Similar to the case where the user is online as described above, the user online center service maintains the user's online status, so that the user offline message can be obtained from the user online center service.

[0043] Furthermore, since the user's online friend list only exists during the user's current online life cycle, the user's online friend list is destroyed after the user goes offline.

[0044] However, in order to avoid the friend online list query logic and abnormal execution of the online and offline logic caused by the user's repeated online and offline operations in a short period of time, for example, due to network fluctuations causing repeated online and offline operations in a short period of time, and the user's active multiple online and offline operations in a short period of time, the user offline logic is also set accordingly in the embodiments of the present application.

[0045] That is, in the embodiment of the present application, it is possible to determine whether the user is repeatedly offline by obtaining the offline frequency control parameter. If the user is repeatedly offline in a short period of time, no operation is performed and the user's existing status is maintained. If the user is truly offline, the user's friends in the online friend list are asynchronously notified that the user is offline, thereby modifying the user's status in the friends list to offline, and destroying the user's online friend list.

[0046] In addition, as described above, even if the user repeatedly goes online and offline in a short period of time, if the user is offline for the first time, in order to avoid the user not really going offline, for example, going online quickly due to a short network interruption, a delay message with the same length as the offline frequency control parameter can be first sent to the user online center service, and the following delayed offline message logic is executed, including:

[0047] 1. Query the online center service of the user to verify whether the user is really offline. If the user is still online, no action will be taken;

[0048] 2. Obtain the online list of the user's friends;

[0049] 3. Reset the online frequency control parameters of the user so that the user can go online again; and this operation can also ensure that the user has not been online for a period of time and can be regarded as truly offline;

[0050] 4. Asynchronously notify the online list of the user's friends that the user has gone offline, and modify the status of the user in the friends list to offline.

[0051] That is, in the real-time synchronization method of user friend online relationships in a high-concurrency scenario according to an embodiment of the present application, when a user goes offline, the user friend online center receives a user offline message from a user online center service of the user application and performs a user offline operation including: obtaining an offline frequency control parameter to determine whether the user goes offline again; in response to the user repeatedly going offline, not performing the user offline operation and maintaining the user's existing status; and, in response to the user not going offline again, sending a delay message with the same duration as the offline frequency control parameter to the user online center service.

[0052] Furthermore, in the above-mentioned method for real-time synchronization of online relationships of users' friends in high-concurrency scenarios, it further includes: querying the user's online center service to verify whether the user has gone offline; in response to the user being online, not performing any operation; in response to the user being offline, obtaining the online list of the user's friends; resetting the user's online frequency control parameters; and asynchronously notifying the user's online list of friends that the user has gone offline, and modifying the status of the user among the friends to be offline.

[0053] In addition, according to the real-time synchronization method of user friend online relationships in a high-concurrency scenario in accordance with an embodiment of the present application, in addition to the user friend online center executing user online operations and user offline operations to query the friend online list and destroy the friend online list, the logic of adding and deleting friends can also be executed.

[0054] That is, in the real-time synchronization method of user-friend online relationships in a high-concurrency scenario according to an embodiment of the present application, it further includes: when a user deletes a friend, the user friend online center receives a friend deletion message from the friend service and performs a friend deletion operation.

[0055] Furthermore, in the real-time synchronization method of user friend online relationships in a high-concurrency scenario according to an embodiment of the present application, it further includes: when a user adds a friend, the user friend online center receives a friend adding message from a friend service and performs a friend adding operation.

[0056] Here, when adding a friend, first determine whether the adding person, that is, the user's friend online list, exists, and if so, add the added person. In addition, the user's friend online center can also determine whether the added person's friend online list exists, and if so, add the adding person, that is, the user.

[0057] Therefore, in the real-time synchronization method of user friend online relationships in a high-concurrency scenario according to an embodiment of the present application, when a user adds a friend, the user friend online center receives a friend adding message from the friend service of the user application and performs a friend adding operation including: determining whether the user's friend online list exists; in response to the existence of the user's friend online list, adding the added person; determining whether the added person's friend online list exists; and, in response to the existence of the added person's friend online list, adding the user.

[0058] In addition, when deleting a friend, the other party is deleted from the online friend list of both parties. However, because deleting a friend will cause concurrent anomalies with going online and offline: if you delete a friend online, in a concurrent situation, after the online operation queries the online friend list, the friend is just deleted, and the processing logic of the online friend list will add the friend again, resulting in the friend still being able to see the other party online in the online friend list. Therefore, it is necessary to add an asynchronous delay to delete the online status of both friends.

[0059] Therefore, in the real-time synchronization method of user friend online relationships in a high-concurrency scenario according to an embodiment of the present application, when a user deletes a friend, the user friend online center receives a friend deletion message from the friend service of the user application and performs a friend deletion operation including: deleting each other from the online friend lists of the user and the deleted friend; and, in response to the user being online, asynchronously delaying the deletion of the online status of both friends.

[0060] Application Examples

[0061] Figure 2 This is an application example of the method for real-time synchronization of online relationships of user friends in a high-concurrency scenario according to an embodiment of the present application. Here, the method for real-time synchronization of online relationships of user friends in a high-concurrency scenario according to an embodiment of the present application is applied to a backend server, which maintains communication with the client through a user service.

[0062] like Figure 2 As shown, the full name of Kafka is Apache Kafka, which is an open source messaging system that can play the role of "filling valleys with peaks" in the system, and can also be used for asynchronous processing of massive data in heterogeneous and distributed systems.

[0063] When a user opens an application, the application service reads the information that the user is using the application, and sends a "user online" message to the user online center service through Kafka. The user's friend online center reads this "user online" message from the user online center service in real time and performs the user online operation as described above.

[0064] When the user no longer uses the application, the user application is closed, and the application service sends a "user offline" message to the user online center service through Kafka, and the user friend online center reads this "user offline" message from the user online center service in real time and performs the user online operation as described above.

[0065] Since Kafka has the advantages of low latency, high performance, and high throughput, the logical processing of friends going online and offline can be made asynchronous through Kafka.

[0066] In addition, in the embodiment of the present application, due to various reasons such as network delays and service freezes, the "user offline" message may arrive before the "user online" message in the online and offline messages transmitted through Kafka, resulting in data anomalies. In addition, since the network conditions of each user are different, users may repeatedly go online and offline in a short period of time due to network problems, greatly increasing the number of Kafka messages and service pressure.

[0067] Therefore, in the embodiment of the present application, the Kafka message can be further screened by the delayed message of RocketMQ. Here, RocketMQ is a distributed message middleware with the advantages of low latency, high reliability, scalability, ease of use, etc., and supports delayed messages.

[0068] In this way, RocketMQ can delay the processing of "user offline" messages to prevent the data confusion mentioned in the first point above. Specifically, when Kafka processes messages, it determines whether it is necessary to send delayed offline messages through the offline frequency control parameters. In addition, through the online and offline frequency control parameters and delayed messages, the repeated messages caused by network jitter in a short period of time can be turned into one online message and one delayed offline message. In this way, the message volume is changed from N to 2, so that it can carry higher concurrent processing capabilities.

[0069] Of course, those skilled in the art will understand that although Kafka and RocketMQ are used as examples in this application example, in the embodiments of the present application, other message mechanisms that can implement the functions of the real-time synchronization method of user friend online relationships in the high concurrency scenario as described above can also be used.
