[0043] Figure 1 This is a flowchart of a data repair method provided in an embodiment of the present disclosure. The method can be executed by a data repair device, which can be executed by software and / or hardware. The device can be configured on a server, which can be an electronic device such as a server. The method can be applied in a session scenario.

[0044] like Figure 1 As shown, the technical solutions provided by the embodiments of this disclosure include:

[0045] S110: Receives session messages sent by the session sender and stores them in the cloud database.

[0046] In this embodiment of the disclosure, in a scenario involving two user sessions, the session sender sends session messages to the server, the server receives the session messages sent by the session sender, and stores the session messages in a cloud database. The session sender can be a device that sends the session, or it can be a client that sends the session.

[0047] S120: Send the session message to the session receiving end so that the session receiving end stores the session message in its local session database.

[0048] In this embodiment of the disclosure, the session receiving end can be a session receiving device or a session receiving client.

[0049] In this embodiment, the server can send session messages to the receiver, and the receiver stores the session messages in its local session database. Under normal session conditions, the session messages of the sender, server, and receiver are consistent. However, during the process of the server sending session messages to the receiver, network issues or technical problems may cause the server to fail to successfully send the session messages. The server may mistakenly believe that the messages have been sent, leading to inconsistencies between the sender and receiver. Therefore, the server needs to perform differential analysis between the cloud database and the receiver's session database to determine if any session messages are lost, and then resend the lost messages.

[0050] S130: Perform differential processing between the cloud database and the session database of the session receiving end.

[0051] In this embodiment of the disclosure, the triggering condition for the server to differentiate between the cloud database and the session database of the session receiver may be a time interval, or it may be the detection of a fault, or other triggering conditions.

[0052] In one embodiment of this disclosure, optionally, differential processing of the cloud database and the session database of the session receiving end includes: differential processing of the cloud database and the session database of the session receiving end; if the sessions in the cloud database and the session database of the session receiving end are the same, differential processing of the session messages in each session.

[0053] Specifically, in a session scenario, multiple sessions may be created. Session differential can be performed first between the cloud database and the session database at the receiving end. This involves comparing whether the sessions in the two databases are identical. If the sessions are identical, then the session messages within each session are compared to find the missing session messages hierarchically, thus improving differential efficiency. Specifically, sessions can be compared by checking if their session IDs are the same, and session messages can be compared by checking if their session message IDs are the same.

[0054] In one embodiment of this disclosure, optionally, the differential processing of session messages in each session includes: segmenting the session messages in each session; comparing whether the first session message and the last session message are the same for a target session message segment in the cloud database and the session database of the session receiving end; if not, comparing whether the intermediate session messages of the target session message segment are the same; if not, taking the session message segment from the first session message to the intermediate session message as the target session message segment, or taking the session message segment from the intermediate session message to the last session message as the target session message segment, and returning the operation of comparing whether the first session message and the last session message are the same, until the search is completed.

[0055] In this embodiment of the disclosure, the session messages in each session can be segmented and differentiated. For example, the IDs of session messages 1-100 can be checked first to see if they are the same, then the IDs of session messages 101-200 can be checked sequentially, and so on. For a target session message segment, if the first session message in the target session message segment in the two databases is different, and the last session message is also different, then the intermediate session messages can be checked for similarity, and so on, thereby finding the different session messages and identifying the lost session messages. For example, in a session message segment, if the IDs of session messages 101 and 200 are both different, the intermediate session message (session message 150) can be checked for similarity. If the ID of session message 150 is the same, then an intermediate session message can be selected from session messages 101 and 150, or from session messages 150 and 200, and the ID of this intermediate session message can be checked for similarity, thereby successively finding the different session messages in the two databases in the session message segment.

[0056] Therefore, by segmenting and differentiating the session messages in each session, the efficiency of session message differentiation can be improved, and the speed of finding lost session messages can be increased.

[0057] S140: Based on the differential results, determine the session messages lost by the session sender and the session receiver during the session.

[0058] In this embodiment of the disclosure, the difference result can be the result obtained by differentiating the session data of the cloud database and the session receiving end, including whether the sessions in the two databases are the same, and whether the session messages in the sessions are the same.

[0059] In one embodiment of this disclosure, optionally, determining the lost session messages between the session sender and the session receiver during a session based on the differential result includes: if the session database of the session receiver has lost a first target session relative to the cloud database, the session message corresponding to the first target session is taken as the lost session message between the session sender and the session receiver during the session; if the session database of the session receiver is the same as the session in the cloud database, and the target session message is lost in the second target session, the target session message is taken as the lost session message between the session sender and the session receiver during the session.

[0060] Specifically, if the session database of the receiving end loses a session relative to the cloud database, it means that all session messages in that session are missing. In this case, the session messages in that session are considered lost during the session. If the session database of the receiving end is the same as the session in the cloud database, but a session message is missing in a certain session, that session message is considered lost during the session. This allows for the identification of lost session messages, which is convenient for subsequent resending.

[0061] S150: Resend the lost session message to the session database of the session receiver.

[0062] In this embodiment of the disclosure, the server resends the lost session messages to the session receiver so that the session receiver stores the lost session messages in its local session database. This can ensure the consistency of session messages among the session sender, server, and session receiver, and can avoid the loss of session messages during the session.

[0063] The technical solution provided in this disclosure involves the server performing differential analysis between the cloud database and the session database of the session receiver, and determining the session messages lost during the session between the session sender and the session receiver based on the differential analysis results. The lost session messages are then resent to the session database of the session receiver, which can keep the session messages between the session sender and the session receiver consistent and avoid the loss of session messages.

[0064] Figure 2 This is a flowchart of a title display method provided in this embodiment. In this embodiment, the solution can be combined with one or more optional solutions in the above embodiments.

[0065] In this embodiment, optionally, the step of differentially dividing the cloud database and the session database of the session receiving end includes:

[0066] When a user is detected browsing a set session message, the corresponding session message in the cloud database and the session database of the session receiving end are differentially analyzed.

[0067] like Figure 2 As shown, the technical solutions provided by the embodiments of this disclosure include:

[0068] S210: Receives session messages sent by the session sender and stores them in the cloud database.

[0069] S220: Send the session message to the session receiving end so that the session receiving end stores the session message in its local session database.

[0070] The descriptions of S210-S220 can be found in the descriptions of the above embodiments.

[0071] S230: When it is detected that a user is browsing a set session message, the corresponding session message in the cloud database and the session database of the session receiving end are differentially processed.

[0072] In this embodiment of the disclosure, when a user on the session receiving end wants to browse the settings session messages, they can trigger the operation of browsing the settings session messages. The session receiving end will send a request to the server, and the server will perform differential processing on the corresponding session messages in the cloud database and the session database of the session receiving end based on the request. The settings session messages can be one or more session messages.

[0073] For example, when a user wants to browse 1-100 messages in a session, the session receiver sends a request to the server. Based on this request, the server performs a differential search between the cloud database and the session receiver's session database for the 1-100 messages in that session to find any lost messages during the session. The server then resends the lost messages to the session receiver's session database. When the user browses 1-100 messages, they can view the complete session messages from their local session database.

[0074] Therefore, by monitoring when a user browses the configured session messages, the corresponding session messages in the cloud database and the session database of the session receiver are differentiated, allowing the user to view the complete session messages and ensuring the consistency of session messages between the session receiver and the session sender.

[0075] S240: Based on the differential results, determine the session messages lost by the session sender and the session receiver during the session.

[0076] S250: Resend the lost session message to the session database of the session receiver.

[0077] Figure 3 This is a flowchart of a data repair method provided in this embodiment. In this embodiment, the solution can be combined with one or more optional solutions in the above embodiments.

[0078] In this embodiment, optionally, the step of differentially dividing the cloud database and the session database of the session receiving end includes:

[0079] The cloud database and the session database of the session receiving end are differentially analyzed at set intervals; or,

[0080] In the event of a detected session failure, the cloud database and the session database of the session receiving end are differentiated.

[0081] like Figure 3 As shown, the technical solutions provided by the embodiments of this disclosure include:

[0082] S310: Receives session messages sent by the session sender and stores them in the cloud database.

[0083] S320: Send the session message to the session receiving end so that the session receiving end stores the session message in the session database of its local end.

[0084] S330: Perform differential analysis between the cloud database and the session database of the session receiving end at set intervals; or, if a session failure is detected, perform differential analysis between the cloud database and the session database of the session receiving end.

[0085] In this embodiment, a timer can be set on the server side to perform differential analysis between the cloud database and the session database of the session receiving end at set intervals. The set interval can be configured according to session requirements or external network conditions. By performing differential analysis between the cloud database and the session database of the session receiving end at set intervals, lost session messages can be periodically monitored and resent, ensuring the consistency of session messages between the two ends.

[0086] In this embodiment of the disclosure, the session failure may be a network failure or a technical failure, etc. The session failure may cause the loss of session messages when the server sends session messages to the session receiver. Therefore, when a session failure is detected, it is necessary to perform differential analysis between the cloud database and the session database of the session receiver to determine the lost session messages and resend them to ensure the consistency of session messages between the two ends and to ensure normal sessions.

[0087] S340: Based on the differential results, determine the session messages lost by the session sender and the session receiver during the session.

[0088] S350: Resend the lost session message to the session database of the session receiver.

[0092] S420: The server receives the session message sent by the session sender and stores it in the cloud database.

[0093] S430: The server sends the session message to the session receiver.

[0094] S440: The session receiving end receives the session message and stores the session message in its local session database.

[0095] S450: The server performs differential processing between the cloud database and the session database of the session receiving end.
