Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Summary of the application
In order to ensure the normal operation of the whole hybrid cloud environment, it is necessary to further confirm whether data consistency exists between the public cloud and the private cloud after data synchronization, that is, to perform data verification.
In the existing data verification, one way is to judge whether the public cloud and the private cloud have data consistency by comprehensively comparing all data contents in the public cloud and the private cloud. However, the way of comparing the data comprehensively consumes a lot of time and calculation power, and the checking efficiency is low.
Another way of data verification is to compress the complete data in the public cloud. And calculating the compressed data by the public cloud by using an encryption algorithm to obtain corresponding encryption information. After the compressed data are synchronized to the private cloud, the private cloud calculates the compressed data by using the same encryption algorithm, and corresponding encryption information is obtained again. And then, verifying according to the encrypted information obtained by the two calculations, thereby determining the data consistency. However, in the above verification method, once the verification fails, it indicates that an error may occur in the data compression process, so that data compression and data synchronization must be performed again. The above-described process of data compression also consumes a significant amount of time and computational power. Data verification may also be inefficient if recompression is repeated due to verification failure.
That is, in the prior art, a method for efficiently checking data is lacking.
Exemplary method
Therefore, embodiments of the present invention provide a data verification method to solve at least the above technical problems in the prior art.
The method in this embodiment will be applied to the first platform. The first platform is a cloud platform that performs data synchronization in the cloud environment. Usually, the first platform is a public cloud, i.e. data synchronization is performed from the public cloud to a private cloud. In other cases, it is not excluded that the first platform is a private cloud, i.e. the private cloud synchronizes data to the public cloud. In contrast, the cloud platform that accepts data synchronization is referred to as the second platform in this embodiment. As shown in fig. 1, the method in this embodiment includes the following steps:
In this embodiment, the target data is complete data that needs to be synchronized from the first platform to the second platform. And determining verification information from the target data by using the verification rule so as to perform subsequent data verification. In this step, the first platform determines the first verification information by using the verification rule.
Specifically, the check rule may include a version rule and an encryption rule. The process of the first platform determining the first verification information specifically includes:
a first version number of the target data is determined according to the version rule. In particular, the version number may take the form of a timestamp, i.e. the creation time of the target data as its version number. For example, a version number of 20201204123000 means that the target data was created 12 o' clock 30 min 00 sec 12 month 04 year 2020.
First configuration information of the target data may be determined according to the first version number and the data index of the target data. The data index is similar in nature to a "catalog" of target data, i.e., embodying what data content is specifically included in the target data (but not the data content itself of the target data). And constructing first configuration information according to the first version number and the data index, wherein the first configuration information can embody the data content corresponding to the target data of the version. In the first configuration information, the first version number and the data index may be in a key-value data format. With the first version number as the key value and the data index as the value.
And carrying out encryption calculation on the target data according to the encryption rule to determine first encryption information of the target data. The encryption rule may be established based on an encryption algorithm commonly used in the prior art, which is not limited in this embodiment.
Preferably, the encryption rule in this embodiment may use an MD5 encryption algorithm. The first N pieces of data and the last N pieces of data in the target data can be extracted by using an MD5 encryption algorithm to carry out operation, so that first encryption information is obtained. Wherein, N is the quantity set according to the requirement.
That is to say, unlike the prior art, in the present embodiment, the encryption operation is performed on a part of the target data in a manner similar to "sampling", so that the consumption of the calculation power can be reduced, and the verification efficiency can be improved. The first configuration information and the first encryption information are determined, that is, the first configuration information and the first encryption information can be used together as the first verification information.
And 102, transmitting the target data and the check rule to the second platform so that the second platform determines second check information according to the target data and the check rule.
The target data is synchronized from the first platform to the second platform, and the specific synchronization process can be implemented by using the existing openAPI interface, which is not described herein. At the same time, the validation rules may be sent by the first platform to the second platform. After the second platform obtains the target data and the check rule, the check rule can be used for determining the check information from the target data in a similar way, namely determining the second check information. The second check information is calculated in the same manner as the first check information, and the description thereof is not repeated.
And 103, performing data verification according to the first verification information and the second verification information to determine a verification result corresponding to the target data.
In theory, the first check information and the second check information are based on the same target data and the same check rule in the operation process, so that the actual contents of the two should be the same. That is, if the data before and after synchronization has consistency, the first check information and the second check information are necessarily the same. Otherwise, if the data before and after synchronization do not have consistency, the first check information and the second check information are the same.
In this embodiment, data verification is implemented according to the rule, that is, whether the first verification information and the second verification information are consistent or not is compared, so as to determine whether target data synchronized between the first platform and the second platform have consistency or not, thereby obtaining a verification result.
When the verification result corresponding to the target data is successful, the verification result can be sent to the second platform, so that the second platform determines the target data as the current version data, namely, the data synchronization is judged to be successful. The second platform may then use the current version data normally.
When the verification result corresponding to the target data is verification failure, the first platform can transmit the target data to the second platform again, namely, synchronization is carried out again. The second platform may perform a new operation according to the target data obtained by resynchronization and the previously obtained verification rule, determine third verification information, and perform a new verification using the third verification information. In other words, the above steps 102 to 103 are repeated until the verification is passed. Of course, if the continuous verification fails for a specific number of times, the synchronization can be stopped and other processing modes can be adopted according to actual conditions.
In the embodiment, consistency verification is performed based on partial data in the target data, so that the problem that comprehensive verification consumes a large amount of time and computing power is solved. Meanwhile, target data does not need to be compressed and decompressed, resynchronization can be directly carried out when verification fails, and repeated recompression during verification failure is avoided.
According to the technical scheme, the beneficial effects of the embodiment are as follows: and performing data verification according to the first verification information and the second verification information to determine a verification result corresponding to the target data, so that consistency verification based on partial data in the target data is realized, compression and decompression of the target data are not required, resynchronization can be directly performed when the verification fails, and the efficiency of data verification is improved.
Fig. 2 shows another embodiment of the data verification method according to the present invention. The method in this embodiment is applied to a second platform, that is, a cloud platform that accepts data synchronization. That is, the method in this embodiment is equivalent to the flow on the second platform opposite to the method in the embodiment shown in fig. 1. In this embodiment, the method includes the steps of:
Similar to the determination manner of the first check information described in step 101, in the present embodiment, the check rule includes a version rule and an encryption rule; determining the second check-up information according to the target data and the check-up rule includes: determining a second version number of the target data according to the version rule; determining second configuration information of the target data according to the second version number and the data index of the target data; carrying out encryption calculation on the target data according to the encryption rule to determine second encryption information of the target data; and determining second check-up information according to the second configuration information and the second encryption information.
After determining the second check-up information, the second platform sends the second check-up information to the first platform, so that the data check-up method executed in the first platform proceeds to step 103.
In addition, if the verification result of the first platform is verification failure, the data synchronization is carried out again. The second platform receives the target data sent by the first platform again, and determines third verification information according to the target data and the verification rules; and sending the third verification rule to the first platform so as to be convenient for verifying again.
