Description
Technical Field
The present application relates to the field of computer application technologies, and in particular, to a quota management method, apparatus, device, and storage medium.
Background
In a distributed object storage system, an access interface is provided for a user through a service Gateway (RGW), while a quota management function is provided for the user. Through quota management, the number of objects and the size of space which are allowed to be uploaded by each user can be managed, and the number of objects and the size of space which are allowed to be uploaded by the user under a certain bucket can also be managed. When the service gateway needs to realize quota management, quota information of a user needs to be counted in real time, and then whether the object is allowed to be uploaded or not is determined according to the quota information.
In the existing quota management implementation scheme, when a service gateway is started, quota information is loaded from a storage pool and cached in a memory, when a user uploads, deletes and copies an object, whether quota information cached in the memory exceeds a period or not is judged, if the quota information exceeds the period, the quota information is reloaded from the storage pool, whether the user operation is allowed or not is determined by using the quota information, and if the quota information does not exceed the period, whether the user operation is allowed or not is determined by directly using the quota information in the memory. And if the user operation is allowed, further updating the quota information, and writing the updated quota information into the storage pool when a set time interval is reached.
This approach is not problematic in the case where only one service gateway is deployed in a distributed object storage system. However, problems arise if multiple service gateways are deployed in a distributed object storage system. For example, when one service gateway updates quota information and a timing time interval does not arrive and a storage pool is not written yet, other service gateways do not know the change of quota information, which causes inconsistency of quota information used by different service gateways, thereby causing confusion of user operations on objects and affecting system performance.

Detailed Description
In the prior art, in order to solve the problem of inconsistency of quota information cached in a memory by different service gateways, the quota information of one service gateway is changed, and a notification message is sent to other service gateways.
As shown in fig. 1, the distributed object storage system simultaneously supports three service gateways, namely, RGW1, RGW2, and RGW3, a user initiates a request for uploading an object to RGW1, after receiving the request, RGW1 determines whether a quota of the user exceeds, if the quota exceeds, an operation failure (not shown in the figure) is directly returned to the user, if the quota does not exceed, local quota information is modified, then quota change is notified to other service gateways, that is, RGW2 and RGW3, RGW2 and RGW3 receive a quota change notification of RGW1, update respective local quota information, return a notification response to RGW1, and after receiving the notification responses of RGW2 and RGW3, RGW1 returns a request response to the user, and successfully replies an upload response.
That is, when the quota information of one service gateway changes, all other service gateways need to be notified, and the processing can not be continued until notification responses returned by all other service gateways are received. In this way, when the number of service gateways is small and the service load pressure is low, quota information is synchronized quickly and quota control is also accurate. However, when the number of service gateways is large, especially when the service load is heavy, the waiting time is long due to waiting for the responses of all other service gateways, and the system performance is greatly affected.
In view of this, the present application provides a quota management method, which may be applied to a quota management device. The quota management device can be deployed in a distributed object storage system, the distributed object storage system can simultaneously support a plurality of service gateways, the service gateway of the distributed object storage system is an RESTful object storage cluster access interface, converts a RESTful access request of a user into access to an object storage cluster, and returns an access result to the user. The quota management device may be in communication with each service gateway. When receiving a quota change request sent by any one service gateway of the distributed object storage system, the quota management device modifies the total quota information according to the total quota information when determining that the quota change request does not exceed the quota of the corresponding user, and returns a confirmation response message to the service gateway, so that the service gateway can correspond to the operation request of the user when receiving the confirmation response message. The quota management device maintains the total quota information, and the service gateway can communicate with the quota management device, so that quota change notification and waiting delay between the service gateways are reduced, the problem of operation confusion of a user on an object can be avoided, and the influence of quota management on system performance is reduced.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and 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.
Referring to fig. 2, an implementation flowchart of a quota management method provided in an embodiment of the present application is shown, where the method may include the following steps:
s210: a first quota change request sent by a first service gateway of a distributed object storage system is received.
The first quota change request is: and the first service gateway sends the uploading request under the condition that the uploading request does not exceed the quota of the first user according to the local quota information when receiving the uploading request of the first user to the first object.
In this embodiment of the present application, the first service gateway is any one of a plurality of service gateways that are simultaneously supported by the distributed object storage system. Each service gateway of the distributed object storage system can obtain quota information in advance and store the quota information, that is, each service gateway maintains local quota information. The quota information may include, for each user, the number of objects and the occupied space size currently allowed to be uploaded by the user, and/or the number of objects and the occupied space size allowed to be uploaded by the user under each bucket, and may further include the total number of objects and the occupied space size allowed to be uploaded by the user, and/or the total number of objects and the occupied space size allowed to be uploaded by the user under each bucket.
When the first service gateway receives an upload request of a first user for the first object, whether the upload request exceeds a quota of the first user may be determined according to the local quota information. For example, the size of a space that a first object to be uploaded by a first user needs to occupy is 50M, the first service gateway indicates, according to the local quota information, that the upload request exceeds the quota of the first user if it is determined that the size of the space currently allowed to occupy by the first user is 40M or the number of objects currently allowed to be uploaded by the first user is 0, and indicates that the upload request does not exceed the quota of the first user if it is determined that the size of the space allowed to occupy by the first user is 100M and the number of objects currently allowed to be uploaded by the first user is not 0. For another example, if the first user wants to upload the first object to the first bucket, and if it is determined that the number of objects currently allowed to be uploaded to the first bucket by the first user is 0, it indicates that the upload request exceeds the quota of the first user.
When the first service gateway determines that the upload request exceeds the quota of the first user, upload failure information can be directly returned to the first user.
The first service gateway may send a first quota change request to the quota management device when determining that the upload request does not exceed the quota of the first user, where the first quota change request may carry quota information to be modified.
It is understood that in practical applications, the user's copy request for the object may also be a special case of the upload request, since all of them need to continuously occupy space.
When receiving the first quota change request sent by the first service gateway, the quota management device may continue to perform the operation of step S220.
S220: and determining whether the first quota change request exceeds the quota of the first user according to the total quota information.
In this embodiment of the present application, the quota management device may maintain a total quota information, and may modify the total quota information according to a quota change request sent by each service gateway, that is, the total quota information is the most complete and latest quota information in the distributed object storage system.
When receiving the first quota change request sent by the first service gateway, the quota management device further determines whether the first quota change request exceeds the quota of the first user according to the total quota information. The specific determination method may be performed by referring to a manner in which the first service gateway determines whether the upload request exceeds the quota of the first user according to the local quota information, which is not described in this embodiment of the present application again.
S230: and if the first quota change request is determined not to exceed the quota of the first user, modifying the total quota information, and returning a first confirmation response message to the first service gateway, so that the first service gateway responds to the uploading request of the first user when receiving the first confirmation response message.
When receiving the first quota change request sent by the first service gateway, the quota management device further determines whether the first quota change request exceeds the quota of the first user according to the total quota information. If it is determined that the first quota change request does not exceed the quota of the first user, it indicates that the upload request of the first user to the first object is legal, and in this case, the quota management device may modify the total quota information based on the quota information to be modified carried by the first quota change request.
For example, the size of the first object is 50M, the quota information to be modified is the number of objects allowed to be uploaded by the first user minus 1, the size of the space occupied by the first user is allowed to be reduced by 50M, the number of objects allowed to be uploaded by the first user is reduced by 1 in the current total quota information, and the size of the space occupied by the first user is allowed to be reduced by 50M.
Meanwhile, if the quota management device determines that the first quota change request does not exceed the quota of the first user, a first confirmation response message may be returned to the first service gateway, so that the first service gateway may respond to the upload request of the first user and may return a corresponding response message such as upload success to the first user when receiving the first confirmation response message.
The first service gateway is any one of a plurality of service gateways simultaneously supported by the distributed object storage system, namely, any one service gateway of the distributed object storage system can send a quota change request to the quota management device when quota changes, and the quota management device determines whether quota is exceeded or not according to the maintained total quota information.
By applying the method provided by the embodiment of the application, when receiving a quota change request sent by any one service gateway of the distributed object storage system, the quota management device modifies the total quota information according to the total quota information when determining that the quota change request does not exceed the quota of the corresponding user, and returns a confirmation response message to the service gateway, so that the service gateway can correspond to the operation request of the user when receiving the confirmation response message. The total quota information is maintained in the quota management device, the service gateway is communicated with the quota management device, the legality of the operation request of the user can be accurately determined based on the total quota information, the problem that the operation of the user on the object is disordered can be avoided, and the influence of quota management on the system performance is reduced.
In an embodiment of the present application, in a case that it is determined that the first quota change request exceeds the quota of the first user, the method may further include the following steps:
and returning a refusal response message to the first service gateway so that the first service gateway refuses the uploading request of the first user when receiving the refusal response message.
It can be understood that, in this embodiment of the present application, any one of the service gateways of the distributed object storage system may send a quota change request to the quota management device when there is a quota change, so that the total quota information maintained by the quota management device is always the latest and the most complete.
After receiving a first quota change request sent by a first service gateway, the quota management device determines whether the first quota change request exceeds a quota of a first user according to the total quota information. If it is determined that the first quota change request exceeds the quota of the first user, indicating that the upload request of the first user for the first object is illegal, a rejection response message may be returned to the first service gateway, so that the first service gateway may reject the upload request of the first user when receiving the rejection response message, for example, return the rejection message to the first user.
Therefore, whether the operation of the user on the object is legal or not can be accurately determined according to the total quota information, and illegal operation is timely avoided.
In one embodiment of the present application, the method may further comprise the steps of:
the method comprises the following steps: receiving a second quota change request sent by the first service gateway, wherein the second quota change request is as follows: the first service gateway sends out when receiving a deletion request of a first user for a second object;
step two: and according to the second quota change request, modifying the total quota information, and returning a second confirmation response message to the first service gateway, so that the first service gateway responds to the deletion request of the first user when receiving the second confirmation response message.
For convenience of description, the above two steps are combined for illustration.
In practical application, a user can delete an object in the distributed object storage system or an object under a certain bucket as required. The first service gateway may send a second quota change request to the quota management device when receiving a deletion request of the first user for the second object, because if the user wants to delete a certain object, the change of the quota information corresponding to the user is necessarily caused.
When receiving the second quota change request sent by the first service gateway, the quota management device may modify the total quota information according to the second quota change request. Specifically, the total quota information may be modified based on the quota information to be modified carried by the second quota change request.
For example, the size of the second object is 50M, the quota information to be modified is the number of objects allowed to be uploaded by the first user plus 1, the size of the space allowed to be occupied by the first user plus 50M, the number of objects allowed to be uploaded by the first user plus 1 in the current total quota information, and the size of the space allowed to be occupied by the first user plus 50M.
When receiving the second quota change request sent by the first service gateway, the quota management device may also return a second confirmation response message to the first service gateway. Thus, when receiving the second acknowledgement message, the first service gateway may respond to the deletion request of the first user to delete the second object, and may return a deletion success message to the first user at the same time.
When quota changes, each service gateway of the distributed object storage system can send a quota change request to the quota management device, so that the total quota information maintained by the quota management device is always up-to-date and most complete. The validity of the operation request of the user can be accurately confirmed based on the total quota information.
In one embodiment of the present application, the method may further comprise the steps of:
and when the set time interval is reached, sending the total quota information to each service gateway of the distributed object storage system, so that each service gateway takes the received total quota information as local quota information for determining whether to respond to an operation request of a user.
In the embodiment of the present application, a time interval may be preset. When the set time interval is reached, the quota management device may send the total quota information to each service gateway of the distributed object storage system, so that each service gateway may receive the current most complete and latest total quota information, store the total quota information as local quota information, and determine whether to respond to an operation request of a user based on the current most complete and latest total quota information. The consistency of the local quota information of different service gateways is ensured, and the problem of quota control failure is avoided.
In one embodiment of the present application, the method may further comprise the steps of:
and according to the total quota information, if the quota of the second user is determined to be used up, respectively sending an over-quota notification aiming at the second user to each service gateway of the distributed object storage system.
In this embodiment of the present application, the quota management device maintains the total quota information, and may monitor quota information of each user in the total quota information. And according to the total quota information, if the quota of the second user is determined to be used up, the second user is indicated to be unable to upload the object at present. In the event that the quota of the second user is determined to be exhausted, an over quota notification for the second user may be sent to each service gateway of the distributed object storage system, respectively. After receiving the over quota notification, each service gateway may directly refuse when receiving the upload request of the second user for the object again. The processing efficiency is improved.
The quota of the second user may include the number of objects and the size of occupied space that the second user is allowed to upload, and may further include the number of objects and the size of occupied space that the second user is allowed to upload under a certain bucket. Whenever one of the second user's quotas is exhausted, a corresponding over quota notification for the second user may be sent to each service gateway.
In this embodiment of the present application, the service gateway may locally accumulate relevant quota changes. The service gateway locally accumulates relevant quota changes in two cases:
the first method comprises the following steps: when the service gateway receives an upload request of a user for a certain object, if the upload request does not exceed the quota of the user according to the local quota information, the local quota information may be modified first, and then a quota change request is sent to the quota management device. And when the service gateway receives a confirmation response message returned by the quota management equipment, responding to the uploading request of the user. When the service gateway receives the refusal response message returned by the quota management device, the modified local quota information can be restored.
And the second method comprises the following steps: when receiving an upload request of a user for a certain object, the service gateway may send a quota change request to the quota management device if it is determined that the upload request does not exceed the quota of the user according to the local quota information. When the service gateway receives the confirmation response message returned by the quota management device, the service gateway may modify the local quota information and respond to the upload request of the user. When the service gateway receives the response rejection message returned by the quota management device, the upload request of the user can be directly rejected.
For convenience of understanding, the following describes an embodiment of the present application by taking the quota management process shown in fig. 3 as an example. Likewise, the distributed object storage system supports three service gateways, RGW1, RGW2, RGW3, simultaneously.
A user sends a request for uploading objects to the RGW1, and the RGW1 receives the request for uploading the objects and judges whether the request exceeds the quota of the user or not according to the local quota information. If so, an upload failure message (not shown) is returned directly to the user. If not, the local quota information is updated, and then a quota change request is sent to the quota management device.
And after receiving the quota change request, the quota management device updates the statistics of the related quota and then judges whether the quota exceeds the quota of the user or not according to the total quota information. If so, a reject response message is returned to RGW1, and RGW1 rejects the user's upload request and restores the modified local quota information (not shown). And if the total quota information is not exceeded, updating the total quota information, returning a confirmation response message to the RGW1, and further returning a request response to the user by the RGW1 to respond to the uploading request of the user.
And if the quota management device determines that the quota of the user is exhausted according to the total quota information, the quota management device sends an over quota notification to the RGW1, the RGW2 and the RGW3 respectively, and the RGW1, the RGW2 and the RGW3 do not process the related upload request of the user any more.
Through comparison between the quota management processes in fig. 1 and fig. 3, it can be seen that, after the quota management device is introduced in the embodiment of the present application, the number of notifications that need to be sent when a quota changes each time is reduced, and only the quota management device needs to be notified without sending a notification to other service gateways.
When the quota management device judges that the quota of a certain user is used up, the quota management device notifies all service gateways, so that the service gateways receiving the notification no longer process the related upload requests. The whole process reduces quota change notification and waiting time delay among the service gateways, and reduces the influence of quota management on system performance. That is to say, in the embodiment of the present application, quota changes of each service gateway are counted in real time by the quota management device, and the uploading operation of the user is controlled in time, and when one service gateway has a quota change, only the quota management device needs to be notified without notifying and waiting for feedback of other service gateways. When the quota management device judges that the quota of a certain user or a storage bucket exceeds the limit, all service gateways are notified. By the technical scheme provided by the embodiment of the application, the influence of distributed quota management on the performance of each service gateway can be effectively reduced, and the real-time effective control of quota can be realized.
In the embodiment of the application, the service gateways of the distributed object storage system belong to the service end, local quota information at each service gateway may not be accurate, and total quota information maintained by the quota management device is the most complete and latest quota information in the distributed object storage system and is accurate information. Each service gateway is responsible for reporting quota change to quota management equipment, then the quota management equipment carries out statistics, and once quota is exceeded, quota exceeding notification can be sent to all service gateways.
Corresponding to the above method embodiment, an embodiment of the present application further provides a quota management apparatus, which is applied to a quota management device, and a quota management apparatus described below and a quota management method described above may be referred to in a corresponding manner.
