Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a data repair method provided by an embodiment of the present invention, where the data repair method may be applied to an electronic device, and the electronic device may be a server, or the electronic device may also be a terminal, and the electronic device may be used to perform data repair. The electronic device is capable of data communication with each storage system for storing user data.
The method may comprise the steps of:
s101: and for each original storage system, judging whether the user data of the target user stored in the target storage system is consistent with the user data of the target user stored in the original storage system by calling a verification plug-in corresponding to the original storage system, and if not, executing step S102.
S102: and determining the stored user data of the target user, and using the original storage system which is inconsistent with the user data of the target user stored in the target storage system as an alternative storage system.
S103: and storing the user data of the target user stored in the alternative storage system to the target storage system by calling the repair plug-in corresponding to the alternative storage system.
Based on the data restoration method provided by the embodiment of the invention, the stored user data of the target user can be determined, and the original storage system which is inconsistent with the user data of the target user stored in the target storage system is synchronized to the user data error of the target storage system. Then, the user data in the original storage system can be stored to the target storage system by calling the repair plug-in corresponding to the original storage system. That is, the user data in the original storage system can be re-synchronized to the target storage system, and further, the accuracy of the user data stored in the target storage system can be improved.
In step S101, each original storage system is used to store a portion of user data of a user. For example, each primary storage system may be used to store one type of user data, e.g., primary storage system 1 for storing user ratings, primary storage system 2 for storing user names, and primary storage system 3 for storing user interest tags. The target storage system may be used to store all types of user data, for example, the target storage system is used to store user ratings, user names, and user interest tags.
When user data stored in each original storage system is synchronized to a target storage system, user data synchronized to the target storage system may be erroneous due to network interruption or the like. For example, the user data is not synchronized to the target storage system, or is erroneous user data synchronized to the target storage system, etc.
Thus, for each original storage system, the electronic device may verify the user data of the original storage system synchronized to the target storage system in order to determine whether the user data of the original storage system synchronized to the target storage system is erroneous.
In one implementation manner, the electronic device may determine whether the user data of the target user stored in the original storage system is consistent with the user data of the target user stored in the target storage system by calling a verification plug-in corresponding to the original storage system.
The verification plug-ins are in one-to-one correspondence with the original storage systems, and each verification plug-in is used for determining whether user data synchronized to the target storage system is in error or not in the original storage system corresponding to the verification plug-in.
Plug-ins refer to programs written by a technician based on a specification of an application program interface. Each verification plug-in is stored in a first storage location. The electronic device may invoke the verification plug-ins from the first storage location to verify user data synchronized to the target storage system for each of the original storage systems.
Subsequently, when a new original storage system is added, the verification plug-in corresponding to the new original storage system can be stored to the first storage position. The electronic device may invoke a verification plug-in corresponding to the new original storage system from the first storage location to verify user data synchronized by the new original storage system to the target storage system.
For example, the first storage location may be resources/META-INF/services, and the technician may store verification plug-ins com. * The identity of the original storage system to which IuserInfoValidService corresponds.
Therefore, when a new original storage system is added, a technician only needs to store the verification plug-in corresponding to the new original storage system to the first storage position, that is, when different technicians respectively maintain each original storage system, each person only needs to store the verification plug-in corresponding to each maintained original storage system in the first storage position, and further, the development efficiency can be improved.
In one embodiment of the present invention, referring to fig. 2, before step S101, the method may further include the steps of:
s104: a data verification instruction for user data of a target user is received.
The data verification instruction carries a target user identifier of the target user.
Accordingly, step S101 may include the steps of:
s1011: for each original storage system, user data corresponding to the target user identifier is obtained from the original storage system as first user data by calling a verification plug-in corresponding to the original storage system, and user data corresponding to the original storage system is obtained from the target storage system as second user data in the user data corresponding to the target user identifier.
S1012: it is judged whether or not the first user data is identical to the second user data, if yes, step S1013 is performed, and if no, step S1014 is performed.
S1013: and determining the user data of the target user stored in the target storage system, and conforming to the user data of the target user stored in the original storage system.
S1014: and determining the user data of the target user stored in the target storage system, which is inconsistent with the user data of the target user stored in the original storage system.
In step S104, after synchronizing the user data stored in each original storage system to the target storage system, in order to determine whether the user data of the target user stored in the target storage system is erroneous, a technician may input a data verification instruction (which may be referred to as a target data verification instruction) for the user data of the target user to the electronic device.
In one implementation, a "data check" button may be provided in a display interface of the electronic device, which a technician may click. When the "data check" button is detected to be triggered, the electronic device may display a data check page. Furthermore, the technician can input a target data verification instruction carrying the target user identification of the target user in the data verification page so as to determine whether the user data of the target user stored in the target storage system is in error. Accordingly, the electronic device may receive the target data verification instruction.
For step S1011 and step S1012, for each original storage system, the electronic device may obtain user data (i.e., the first user data) corresponding to the target user identifier from the original storage system by calling a verification plug-in corresponding to the original storage system.
The electronic device may further obtain, from the target storage system, user data (i.e., second user data) corresponding to the original storage system from user data corresponding to the target user identifier by calling a verification plug-in corresponding to the original storage system. For example, each primary storage system is configured to store one type of user data, and the user data corresponding to the primary storage system is the type of user data stored in the primary storage system. The electronic device may then determine whether the first user data is consistent with the second user to determine whether the user data of the target user synchronized by the original storage system to the target storage system is erroneous.
For each of the primary storage systems, if the first user data does not agree with the second user data, indicating that the user data of the target user stored in the target storage system does not agree with the user data of the target user stored in the primary storage system, i.e., indicating that the user data of the target user synchronized by the primary storage system to the target storage system is erroneous, for step S1013 and step S1014.
And if the first user data is consistent with the second user data, indicating that the user data of the target user stored in the target storage system is consistent with the user data of the target user stored in the original storage system, namely indicating that the user data of the target user synchronized to the target storage system by the original storage system is not in error.
In step S102, the electronic device may determine, from among a plurality of original storage systems, an original storage system in which the stored user data of the target user is inconsistent with the user data of the target user stored in the target storage system, as an alternative storage system, that is, an original storage system in which the user data of the target user synchronized to the target storage system is erroneous.
In step S103, after determining the alternative storage system, the electronic device may repair, through the target repair plug-in, the user data of the target user stored in the target storage system by calling a repair plug-in (may be referred to as a target repair plug-in) corresponding to the alternative storage system, that is, the electronic device may store, through the target repair plug-in, the user data of the target user stored in the alternative storage system to the target storage system.
It will be appreciated that there may be one or more alternative storage systems. When the number of the alternative storage systems is multiple, for each alternative storage system, the electronic device can store the user data of the target user stored in the alternative storage system to the target storage system by calling the repair plug-in corresponding to the alternative storage system.
The repair plug-ins are in one-to-one correspondence with the original storage systems. Each repair plug-in is used for repairing the user data of the original storage system corresponding to the repair plug-in, which is synchronized to the target storage system.
Each repair plug-in is stored in a second storage position, the first storage position and the second storage position can be the same, and the first storage position and the second storage position can be different. The electronic device may invoke each repair plug-in from the second storage location to repair the user data stored in the target storage system.
Subsequently, when a new original storage system is added, the repair plug-in corresponding to the new original storage system can be stored to the second storage position, and the electronic device can call the repair plug-in corresponding to the new original storage system from the second storage position so as to repair the user data of the new original storage system synchronized to the target storage system.
Therefore, when a new original storage system is added, a technician only needs to store the repair plug-in corresponding to the new original storage system to the second storage position, that is, when different technicians respectively maintain each original storage system, each person only needs to store the repair plug-in corresponding to each maintained original storage system in the second storage position, and further, development efficiency can be improved.
It will be appreciated that the verification plug-in and the repair plug-in may be different plug-ins, the verification plug-in may be used to verify user data stored in the target storage system, and the repair plug-in may be used to repair user data stored in the target storage system. Or the verification plug-in and the repair plug-in can be the same plug-in, and the plug-in can be used for verifying the user data stored in the target storage system and repairing the user data stored in the target storage system.
In one embodiment of the present invention, referring to fig. 3, before step S103, the method may further include the steps of:
s105: the identity of the alternative storage system is displayed.
Accordingly, step S103 may include the steps of:
S1031: when a data restoration instruction for the alternative storage system is received, user data of the target user stored in the alternative storage system is stored into the target storage system by calling a restoration plug-in corresponding to the alternative storage system.
In step S105, after determining the alternative storage system, the electronic device may display an identification of the alternative storage system. Accordingly, the technician may view the identification of the alternative storage system displayed by the electronic device. The identity of the original storage system is used to represent the type of user data stored by the original storage system. For example, the user data stored in the original storage system is a user name, and the identifier of the original storage system is the user name.
In step S1031, the technician, after browsing the identification of the candidate storage system displayed by the electronic device, may determine that the user data of the target user of the candidate storage system synchronized to the target storage system is in error. Further, the technician may input data repair instructions for the alternative system to the electronic device. Correspondingly, the electronic device can store the user data of the target user stored in the alternative storage system to the target storage system by calling the target repair plug-in.
In one implementation, for each original storage system, the user data of the target user stored in the original storage system may be stored locally after the user data is obtained by the verification plug-in. And after determining that the original storage system is an alternative storage system, the electronic device can store the user data of the target user stored in the original storage system, which is acquired through the verification plug-in, into the target storage system by calling the repair plug-in corresponding to the original storage system.
In one embodiment of the present invention, referring to fig. 4, before step S103, the method may further include the steps of:
s106: and storing the information to be processed comprising the identification of the alternative storage system and the target user identification of the target user into a preset queue.
Accordingly, step S103 may include the steps of:
s1032: when the information to be processed is obtained from the preset queue, user data corresponding to the target user identification is obtained from the alternative storage system by calling the repair plug-in corresponding to the alternative storage system, and the user data is stored in the target storage system.
In step S106, in one implementation manner, after determining the alternative storage system, the electronic device may add the identifier of the alternative storage system and the target user identifier to the preset queue as the information to be processed.
In another implementation manner, under the condition that the identifier of the alternative storage system is displayed, each piece of information to be processed in the preset queue may be that the electronic device sequentially stores the information to be processed in the preset queue after receiving the data repair instruction for each alternative storage system.
For example, the electronic device may encapsulate the information to be processed including the identifier of the alternative storage system and the identifier of the target user into a RMQ (Range Minimum/Maximum Query, maximum/Minimum direction problem) message, and store the encapsulated RMQ message in a preset queue.
In step S1032, the electronic device may sequentially obtain each piece of information to be processed according to the order of the pieces of information to be processed in the preset queue, and obtain the user data corresponding to the target user identifier from the alternative storage system by calling the repair plug-in corresponding to the identifier of the alternative storage system in the information to be processed, and store the user data in the target storage system.

Accordingly, the plug-in 1 corresponds to the original storage system 1, the plug-in 2 corresponds to the original storage system 2, and the plug-in 3 corresponds to the original storage system 3.
The electronic device may receive a target data verification instruction for user data of a target user entered by a technician. Then, for each original storage system (for example, the original storage system 1), the electronic device may obtain, by calling the plug-in 1, user data corresponding to the target user identifier (i.e., first user data) from the original storage system 1, and obtain, from the target storage system, user data corresponding to the original storage system 1 (i.e., second user data) from the user data corresponding to the target user identifier. Then, it is determined whether the first user data is consistent with the second user data, and if the first user data is inconsistent with the second user data, the electronic device may determine that the user data of the original storage system 1 synchronized to the target storage system is in error. Similarly, the electronic device may determine whether the original storage system 2 and the original storage system 3, user data synchronized to the target storage system, are in error.
If the electronic device determines that the original storage system 1 and the original storage system 2 are alternative storage systems, the electronic device may display the identity of the alternative storage systems, i.e. the identity of the storage system 1 and the identity of the original storage system 2.
After the technician browses the identification of the alternative storage system displayed by the electronic device, the original storage system 1 and the original storage system 2 may be determined, and user data synchronized to the target storage system is erroneous. Further, the technician may input data repair instructions for an alternative storage system (e.g., original storage system 1) to the electronic device. When receiving a data repair instruction for the original storage system 1, the electronic device may store information to be processed including the identifier of the original storage system 1 and the identifier of the target user to a preset queue.
The electronic device may acquire each piece of information to be processed in sequence according to the order of the pieces of information to be processed in the preset queue. When the information to be processed including the identifier of the original storage system 1 and the target user identifier is obtained, the electronic device may store the data corresponding to the target user identifier in the original storage system 1 to the target storage system by calling the plug-in 1.
In addition, the electronic device may also determine whether to successfully store the user data corresponding to the target user identifier stored in the original storage system 1 to the target storage system. If the user data corresponding to the target user identifier stored in the original storage system 1 is not successfully stored in the target storage system, the electronic device can store the information to be processed in the preset queue again, and when the information to be processed is acquired from the preset queue, the plug-in 1 is called again to repair the user data of the target user stored in the target storage system.
If the user data corresponding to the target user identifier stored in the original storage system 1 is successfully stored in the target storage system, the electronic device may display a reminder message for successfully repairing the user data of the target user.
