Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.
A user quota function in a distributed storage system is a storage mechanism that manages the allowed capacity of a particular user of the system. The existing user capacity quota function limits the total capacity of the equipment, so that the problem that a large amount of data of the equipment is written at a certain moment and the writing situation of other equipment cannot be written is easily caused. Based on the foregoing technical problem, this embodiment provides a traffic quota method, and specifically please refer to fig. 1, where fig. 1 is a flowchart of a traffic quota method provided in this embodiment, and specifically includes:
s110, the metadata server receives the corresponding relation between the user information sent by the client device and the write-in attribute, wherein the write-in attribute comprises a preset period and a flow threshold of write-in data in the preset period.
In this embodiment, the execution subject is a metadata server. The client device sets a flow control attribute, i.e. a write attribute, for a specified user, and the unique user information representing the user may be user ID, user IP, or user-defined setting, as long as the user can be uniquely represented. It is understood that when the user includes a, b, c, a first write attribute is set for the user a, and the first write attribute includes a first preset period and a first traffic threshold; setting a second writing attribute for the user b, wherein the second writing attribute comprises a second preset period and a second flow threshold; and setting a third write attribute for the user c, wherein the third write attribute comprises a third preset period and a third flow threshold. The client device sends the corresponding relation to the metadata server, and the metadata server manages the corresponding relation in a unified mode. It can be understood that, by defining the flow threshold of the written data in the preset period for the user corresponding to the user information, it can be ensured that other users can successfully write data in the same time, and the network pressure is balanced.
And S120, receiving a flow quota request sent by the client device based on the target user information, and determining a target write attribute corresponding to the target user information according to the corresponding relationship.
In this embodiment, the number of times that the received traffic quota request corresponding to the target user information is within the current preset period is not limited, and the number of times may be the first time or the first time. And after receiving the flow quota request, determining a target write-in attribute corresponding to the target user information according to the corresponding relation, wherein the target write-in attribute comprises a corresponding flow threshold value. It should be noted that, in order to avoid frequent interaction with the metadata server, before writing data, the client device pre-applies for a certain amount of available space from the metadata server, and if the space is available, the client device allows the writing, otherwise, the client device waits until the next cycle to write.
Further, after receiving a traffic quota request sent by the client device based on the target user information, the method further includes: judging whether the target user information corresponding to the client equipment is legal information or not; and if the information is legal, determining the target writing attribute corresponding to the target user information according to the corresponding relation. It can be understood that, even if the target user information is included in the correspondence relationship, when the target user corresponding to the target user information is restricted to be unable to perform the data writing operation within a certain time, the target user information is illegal information within the current time, and then unable to perform the subsequent operation, and when the target user information is legal information, then perform the subsequent operation. Therefore, the safety of writing data is improved by judging whether the target user information is legal information.
And S130, issuing a target flow quota corresponding to the target user information to the client equipment according to the flow quota request and the target write-in attribute so that the client equipment executes write operation according to the target flow quota.
In an implementation manner, a target traffic quota is further defined, please refer to fig. 2, and fig. 2 is a schematic flow chart of the target traffic quota, which includes:
s131, determining a flow quota corresponding to the flow threshold of the target user information according to the flow quota request and the target write attribute.
The traffic quota corresponds to a traffic threshold. The traffic quota is a maximum written traffic value allowed by the target user corresponding to the target user information in the current preset period.
S132, judging whether the flow quota is used in the current preset period.
In this embodiment, it is determined whether the traffic quota is used in the current preset period, and it is understood that the client device corresponding to the target user information using the traffic quota may include the client device related in this embodiment, and of course, other client devices may also log in the target user information to implement the data write-in operation.
S133, if the traffic quota is not used, setting the traffic quota as the target traffic quota.
And S134, if the traffic quota is used, determining the relation between the used traffic quota and zero.
It can be understood that when the traffic quota is used, there are two situations, the first is that the traffic quota is zero after use, and the second is that the traffic quota is greater than zero after use.
And S135, if the flow quota is larger than zero, using the used flow quota as a target flow quota, and issuing the target flow quota to the client device, wherein the used flow quota is a quota quantity obtained by subtracting the used flow quota from the flow quota. If equal to zero, the process is stopped.
It can be understood that, in this embodiment, the user side sets a total capacity, i.e., a traffic threshold, that the specified user, i.e., the user information, allows to write data in a unit time, i.e., a preset period. When setting a write attribute for user information, a client needs to specify two parameters, namely a preset period and a flow threshold. And the system records the total amount S of data written in the statistical period, and when S is smaller than the set flow threshold, the data can be continuously written in the system based on the target user information in the preset period, otherwise, the user is prohibited from continuously writing until the next statistical period starts. In the statistical period, the data volume written by each client device by using the target user information is uniformly reported to the metadata server, so that the accuracy of data statistics is ensured. When each client device writes data, it needs to apply for an available flow quota from the metadata manager, and when the available flow quota in a preset period is exhausted, a user is set to prohibit the write request in the preset period. And after one preset period is finished, issuing an available flow quota to the user again according to the specified flow threshold value, and controlling the data writing in the next preset period. And after the user prohibits writing in the previous preset period, allowing to continuously write data in a new preset period.
The conventional user capacity quota management method cannot limit the write volume of a specified user in unit time, which cannot be applied to an application scenario in which the write flow of the user needs to be limited. The embodiment allows the available flow threshold of the user in the preset period to be specified, so that the data flow threshold written by the user in a certain preset period can be conveniently controlled. The use scenes of the user quota are enriched, and the effect of improving the experience of the user by meeting the use condition of the special scene of the user can be better achieved.
Further, after issuing the target traffic quota corresponding to the target user information to the client device according to the traffic quota request and the target write attribute, the method further includes: receiving a write-in data volume corresponding to target user information sent by client equipment; and calculating the total amount of data written in the current preset period.
Each client device records the written data volume written by the target user information under the client device, the recording mode can be a quantitative mode and a timing mode, and then the written data volume is reported to the metadata server, and the metadata server counts the total written data volume of all the clients in the current preset period. The data is recorded, so that the user can conveniently check related information, and the purpose of tracing is achieved.
Further, after issuing the target traffic quota corresponding to the target user information to the client device according to the traffic quota request and the target write attribute, the method further includes: and receiving a residual flow quota sent by the client device, wherein the residual flow quota is a flow quota remaining after the client device completes the write operation.
If the target flow quota applied by the client device is not used up, the client device does not have continuous write operation, and the client device needs to return the remaining flow quota to the metadata server for use by other clients.
Further, after issuing the target traffic quota corresponding to the target user information to the client device according to the traffic quota request and the target write attribute, the method further includes: the client device executes write operation according to the target flow quota; judging whether the target flow quota is used completely; and if the target flow quota is used completely and the write operation is not completed, sending a new flow quota request to the metadata server in the next preset period so as to complete the write operation.
In this embodiment, the total flow of data written to the user corresponding to the target user information is not limited, but the total flow of data written in the preset period is limited, that is, the flow threshold value. Writing is not allowed until a new traffic threshold is entered. By the method, the situation that a user writes too much data in unit time can be avoided, and the use scenes of storage management are further enriched.
Based on the above technical solution, in this embodiment, a storage management manner is established, in which a traffic written in a preset period is defined for each user according to a corresponding relationship between user information and a write-in attribute, and the write-in traffic is limited, and when a traffic quota request sent by the client device based on target user information is received, a target traffic quota is determined according to the corresponding relationship and the target write-in attribute corresponding to the target user information, so that a situation that a single user writes in excessive data in the preset period is avoided, and user experience is improved.
