For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of 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 some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a logic flow diagram of a method for managing user information of a multi-node tenant, which is provided in an embodiment of the present invention, and is applied to any storage node in a distributed storage system, and includes:
s101: after detecting that the first user information stored by the user equipment generates a state change event, determining a target tenant containing the first user information and a tenant identification of the target tenant according to the changed first user information;
s102: determining first node identifiers of storage nodes of all monitoring target tenants in the distributed storage system according to tenant identifiers;
s103: and sending the first user information and the tenant identification to a storage node of the monitoring target tenant according to the first node identification, so that the storage node of the monitoring target tenant changes the user information of the target tenant stored by the storage node according to the received first user information and tenant identification.
The multi-tenant feature provides unified resource management based on tenant granularity, allocating and managing resources in tenant units. The multi-tenant characteristic can enable a set of storage system to be shared by a plurality of tenants, the running cost of the system is reduced by sharing software and hardware resources, the resource utilization rate of the system is improved, and inter-tenant resource isolation is achieved, so that safety and privacy are ensured.
In an enterprise scene, when unstructured storage is deployed in an enterprise, the enterprise can respectively establish tenants for different departments in an organization, each tenant allocates and manages own resources, the resources among different departments share the same set of physical storage, but the resources are logically isolated according to the tenants, so that the security requirements among different resources are ensured. And the whole tends to cloud deployment (such as rapid development and application of cloud computing platforms of government service cloud, police service cloud and the like) so as to improve the whole resource utilization rate.
It should be noted that, the execution body of the embodiment of the present application is any storage node in a distributed storage system, where each storage node is generally a storage server, and the storage servers are interconnected through a high-speed network, that is, the storage nodes are interconnected through a high-speed network. The number of storage nodes in the distributed storage system is not particularly limited, and a person skilled in the art should make corresponding settings according to the actual situation. Furthermore, the execution body of the embodiment of the present application may be a preset storage node for monitoring the target tenant, or may be a storage node actively monitored by a program under control of the program after the user information of the target tenant stored by the execution body is changed, so long as it is possible to implement that all storage nodes storing the user information of the target tenant are synchronously changed when the state change event occurs in the first user information stored by the execution body.
For step S101, the specific content of the state change event is not limited, and may be, for example, a new user in the target tenant, a user in the target tenant may be deleted, user information of an existing user of the target tenant may be updated, or a combination of any of the above. The method for updating the user information of the existing user of the target tenant may be to modify the name, authority, password, etc. of the existing user, which is not limited in this embodiment, and may be determined according to actual situations.
In order to realize isolation of resources, the data contained in the tenants all carry the tenant identifications of the tenants to which the data belong, namely, the user information of the user under the tenants also carries the tenant identifications of the tenants to which the data belong, the tenant identifications of different tenants are different, and further, the data of different tenants can be distinguished through the tenant identifications, and accordingly, the tenant identifications of the target tenants corresponding to the user information can be determined through the user information.
In step S102, the storage node of the monitoring target tenant may be a preset storage node of the monitoring target tenant, or may be a storage node that is actively monitored by a program after the user information of the target tenant stored in the storage node is changed, so long as it is possible to implement a synchronous change with the storage node in which the state change event occurs when the state change event occurs in the user information of the storage node in which the user information of the target tenant is stored. Further, the embodiment is not limited to a specific method for determining the first node identifications of all the storage nodes of the monitoring target tenants in the distributed storage system according to the tenant identifications, and for a specific determination manner, a person skilled in the art should make a corresponding setting according to the actual situation, for example, the Watch/Notify mechanism may be called according to the tenant identifications, and the first node identifications of all the storage nodes of the monitoring target tenants in the distributed storage system may be determined through the Watch/Notify mechanism.
Among them, the Watch/Notify mechanism is an important communication mechanism in a distributed storage system, and is used to communicate between different storage nodes, so that states between the storage nodes remain consistent. The Watch/Notify mechanism operates in a similar manner to the information publish-subscribe mode, with messages subscribed to by Watch, and messages published by Notify: when a user performs a state change event on user information of a target tenant stored on a storage node, the storage node monitors the target tenant through a communication interface provided by a Watch/Notify mechanism, namely, when the user information of the target tenant stored on the storage node later occurs the state change event, a notification is sent to the storage node monitoring the target tenant through Notify.
For step S103, the embodiment is not limited to a specific transmission mode and transmission flow for transmitting the first user information and the tenant identifier to the storage node of the monitoring target tenant, for example, the first user information and the tenant identifier may be directly transmitted to the storage node of the monitoring target tenant one by one, the first user information and the tenant identifier may be packaged and encoded, after the monitoring encoded information is in a correct format, the encoded information obtained by encoding may be transmitted to the storage node of the monitoring target tenant, or other transmission modes and transmission flows may be used, and a corresponding setting should be made by those skilled in the art according to actual situations.
Further, the embodiment does not limit the specific change operation and change flow of the storage node of the monitoring target tenant to change the user information of the target tenant stored by the storage node according to the received first user information and the tenant identifier, for example, after the first user information and the tenant identifier are received, a state change event generated by the first user information is obtained by analyzing according to the first user information and the tenant identifier, the user information of the target tenant stored by the storage node of the monitoring target tenant is changed, or after the encoded information is received, the received encoded information is decoded to obtain the first user information and the tenant identifier, then a state change event generated by the first user information is obtained by analyzing according to the first user information and the tenant identifier, and the user information of the target tenant stored by the storage node of the monitoring target tenant is changed.
According to the multi-node tenant management method provided by the invention, the storage node storing the user information of the target tenant monitors the target tenant, when the user of the target tenant changes the user information of the target tenant on a certain storage node, the storage node sends the changed user information to all storage nodes monitoring the target tenant in the distributed storage system, and further, when the user information of the target tenant on a certain storage node changes, all the storage nodes containing the user information of the target tenant correspondingly change, so that the user information of the same tenant synchronously changes on different storage nodes, the situation of abnormal data storage is avoided, and the accuracy and reliability of data storage are improved.
Based on the above embodiments:
as a preferred embodiment, after determining the first node identities of all storage nodes of the monitoring target tenant in the distributed storage system according to the tenant identities in S102, the method further includes:
judging whether the second node identification of the second node identification is in the first node identifications of all storage nodes of the monitoring target tenant;
if not, monitoring the target tenant according to the tenant identification.
In a specific embodiment, node identifiers of storage nodes of all monitoring target tenants are obtained, a set formed by the node identifiers is used as a first node identifier, if the first node identifier does not have the same node identifier as the second node identifier of the first node identifier, namely the second node identifier of the first node identifier is not in the first node identifiers of the storage nodes of all monitoring target tenants, the storage node is indicated to be not preset to enable the storage node to monitor the target tenants, and at the moment, the storage node needs to be controlled to monitor the target tenants so as to send a notification to the storage nodes of the same monitoring target tenants, so that other storage nodes synchronously perform an operation of changing user information of the target tenants stored by the storage node according to a state change event.
In the embodiment, whether the second node identifier is in the first node identifiers of all the storage nodes for monitoring the target tenant is judged, so that when the condition that the state change event occurs in the user information of the target tenant exists on the storage node for monitoring the target tenant is not preset, the storage node can monitor the target tenant, each storage node for storing the user information of the target tenant is ensured to monitor the target tenant, synchronous change of the user information of the same tenant among different storage nodes is realized, and the accuracy and the reliability of data storage are improved.
As a preferred embodiment, according to S103, the sending, to the storage node of the monitoring target tenant, the first user information and the tenant identification, includes:
encoding the first user information and the tenant identification to obtain first encoded information;
and sending the first coding information to a storage node of the monitoring target tenant according to the first node identification.
The embodiment does not limit a specific encoding method for encoding the first user information and the tenant identifier, nor limit a specific type of the first encoded information, where the specific encoding method and the specific encoding type depend on a storage node receiving the first encoded information in practical application, and a person skilled in the art should make a corresponding setting according to practical situations.
According to the method, the first user information and the tenant identification are encoded, and then the encoding result is sent to the storage node of the monitoring target tenant, so that the situation that packet loss or data disorder possibly occurs in the process of directly sending the first user information and the tenant identification is avoided, the sending and receiving of the first user information and the tenant identification are more stable, and the reliability and stability of data synchronization are improved.

The embodiment is not limited to a specific receiving method for receiving the second encoded information sent by the storage node of the monitoring target tenant, nor is it limited to a specific decoding process for decoding the second encoded information, and a person skilled in the art should make a corresponding setting according to the actual situation.
In a specific embodiment, a specific change manner of changing the user information of the target tenant stored by the user according to the second user information and the tenant identifier depends on a state change event generated by the user information of the target tenant on the storage node sending the second coding information, for example, when the state change event includes a newly added user in the target tenant, the change manner of changing the user information of the target tenant stored by the user according to the second user information and the tenant identifier may be a change manner of changing the user information of the target tenant stored by the user according to the tenant identifier, and newly adding the user information of the newly added user to the user information stored by the user according to the second user information; when the state change event includes deleting the user in the target tenant, the change mode of changing the user information of the target tenant stored by the user according to the second user information and the tenant identification can be that the user information stored by the user can be found according to the tenant identification, and the user information of the deleted user is correspondingly deleted on the self storage node according to the second user information; when the state change event includes updating the user information of the existing user of the target tenant, the change mode of changing the user information of the target tenant stored by the user according to the second user information and the tenant identifier may be that the user information stored by the user is found according to the tenant identifier, and the user information of the existing user stored by the user is changed correspondingly according to the second user information.
When receiving the second encoded information sent by the storage node of the monitoring target tenant, the embodiment changes the user information of the target tenant stored by the storage node according to the second user information and the tenant identification obtained after decoding, so as to realize synchronous change with the storage node of the monitoring target tenant, meet the service requirement and improve the accuracy and reliability of data storage.
As a preferred embodiment, before S203 changes the user information of the target tenant stored by itself according to the second user information and the tenant identifier, the method further includes:
decoding the second encoded information to obtain a third node identifier of the storage node of the monitoring target tenant;
judging whether the second node identifier of the self is in the third node identifier or not;
if yes, judging that the second coded information is sent by the user, and keeping the user information of the target tenant stored by the user;
if not, the process proceeds to S203 to change the user information of the target tenant stored in the process according to the second user information and the tenant identification.
In this embodiment, whether the code information is sent by itself is determined by whether the second node identifier of the second node is in the third node identifier of the storage node of the monitoring target tenant, and when the code information is monitored to be sent by itself, the user information of the target tenant stored by the second node identifier of the second node is not required to be modified according to the code information, so that repeated change and synchronization operations are avoided, the efficiency of data synchronization is improved, the risk of abnormal data update possibly existing in the change process is also reduced, and the accuracy of data storage is improved.
As a preferred embodiment, the state change event includes any one or a combination of more of adding users in the target tenant, deleting users in the target tenant, and updating user information of existing users of the target tenant.
In a specific embodiment, when the state change event includes a newly added user in the target tenant, the storage node monitoring the target tenant changes the user information of the target tenant stored by itself according to the received first user information and the tenant identifier, so as to find the user information stored by itself according to the tenant identifier, and newly add the user information of the newly added user to the user information stored by itself according to the second user information; when the state change event comprises deleting the user in the target tenant, the storage node of the monitoring target tenant changes the change mode of the user information of the target tenant stored by the storage node according to the received first user information and tenant identification, the user information stored by the storage node can be found according to the tenant identification, and the user information of the deleted user is correspondingly deleted on the storage node according to the second user information; when the state change event includes updating the user information of the existing user of the target tenant, the storage node monitoring the target tenant changes the user information of the target tenant stored by itself according to the received first user information and the tenant identifier, so as to find the user information stored by itself according to the tenant identifier, and correspondingly change the user information of the existing user stored by itself according to the second user information.
