In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
Referring to fig. 1, fig. 1 is a schematic flow chart of a quota management method provided in the present invention, where the quota management method includes:
step S1: receiving data writing requests sent by users from all gateways;
specifically, the distributed storage system comprises a plurality of gateways, a user can send a data writing request to each gateway so as to write data into the distributed storage system, each gateway can send the data writing request to the data storage center after receiving the data writing request, and an execution main body in the application is the data storage center.
Specifically, after receiving a data write request, the subsequent steps may be triggered.
Wherein, each gateway may receive the data write request of any user.
Step S2: judging whether the sum of the current write-in amount of the user and the data variation corresponding to the data write-in request is larger than the quota of the user or not;
specifically, the appeal of the data write request is that the specified data of the user is written into the distributed storage system, which inevitably causes the write volume of the user to change, that is, the data variation, and after receiving the data write request, the present application may first determine whether the data variation corresponding to the data write request causes the write volume of the user to be greater than the quota of the user, that is, the above: judging whether the sum of the current write-in quantity of the user and the data variation corresponding to the data write-in request is larger than the quota of the user, and triggering the execution of the subsequent steps through the judgment of the step so as to limit the write-in quantity of the user.
The quota may be an upper limit value of an available storage resource, such as 10TB, which is allocated to each user in advance, and the embodiment of the present invention is not limited herein.
The existing write volume is the data volume which is written into the distributed storage system by the user at the current moment.
Step S3: if yes, prompting that the quota of the user is used up to each gateway in the distributed storage system, so that each gateway intercepts a data write request of the user with the used-up quota.
Specifically, each gateway is a site that first receives a data write request of a user, and therefore in the embodiment of the present invention, each gateway in the distributed storage system is prompted that a quota of the user is used up, so that when each gateway receives a data write request of each user, each gateway can determine whether the quota of the user is used up (the data write amount reaches the quota) according to a prompt received from the data storage center, and if the quota is used up, the data write request is not sent to the data storage center for processing, that is, the data write request of the user is intercepted, thereby preventing the data write amount of the user from exceeding the quota, and well limiting the data write amount of the user.
The invention provides a quota management method, which can judge whether the data write-in quantity exceeds a quota or not when a data write-in request sent by a user is received from a gateway, and if so, judge that the quota of the user is used up and send a prompt to all gateways, so that all the gateways can intercept the data write-in request of the user with the used-up quota, strictly control the write-in quantity of each user, more evenly and reasonably distribute storage resources, and improve the user experience.
On the basis of the above-described embodiment:
as a preferred embodiment, when receiving a data write request sent by a user from each gateway, the quota management method further includes:
receiving address information of all gateways in the distributed storage system, which is sent by the gateways along with the data writing request;
then, prompting that the user quota is used up to each gateway in the distributed storage system specifically is:
and prompting that the quota of the user is used up to each gateway according to the address information of all the gateways.
Specifically, the gateways send the data write request to the data storage center and simultaneously send the address information of all the gateways in the distributed storage system to the data storage center, so that the data storage center can prompt the quota of the user to be used up to each gateway according to the address information of all the gateways, and the address information is sent along with the data write request, so that the coupling degree between the gateways and the data storage center is not increased.
As a preferred embodiment, the quota management method further includes:
receiving data deletion requests sent by users and address information of all gateways in the distributed storage system from all gateways;
judging whether the sum of the current write-in amount of the user and the data variation corresponding to the data deletion request is larger than the quota of the user;
if not, prompting that the quota of the user is not used up to each gateway so that each gateway can execute the data write request of the user with the unexhausted quota.
Specifically, in addition to the data write request, the user may send a data delete request to the gateways, so in the present application, the data delete request may be received from each gateway, and then it may be determined whether the data delete request may cause the data write amount of the user to exceed the quota (in general, the data delete request may cause the data write amount of the user to be lower than the quota value), if not, it may be determined that the data write amount of the user does not reach the quota value, then it may prompt, to each gateway, that the quota of the user is not used up, and after obtaining this prompt, each gateway may continue to execute the data write request of the user when receiving the data write request of the user in the future.
Specifically, the gateways may also send address information of all the gateways to the data storage center along with the data deletion request, so that the data storage center prompts, according to the address information, that the quota of the user is not used up to each gateway.
As a preferred embodiment, the address information of all gateways sent by each gateway together with the data write request and the data delete request is:
the gateway registration center sends the latest address information of all gateways to each gateway;
when a gateway joins or exits the distributed storage system, the gateway registration center sends the updated address information of all the gateways to each gateway.
Specifically, the gateway registration center is directly responsible for address information of all gateways in the distributed storage system, when a gateway joins the distributed storage system, the gateway registration center can obtain address information of a newly joined gateway, when the gateway exits the distributed storage system, the gateway registration center can delete the address information of the gateway, and when the address information is updated, the gateway registration center can send a piece of latest address information to all the gateways.
Considering that a distributed storage system may include a plurality of storage clusters, each storage cluster includes a plurality of gateways, and network addresses of the gateways in different storage clusters may be repeated, the address information may include unique identifiers UUIDs of the storage clusters where the gateways are located and network addresses of the gateways, so as to distinguish each gateway.
Of course, in addition to sending the address information to the data storage center by using the gateway when sending the data write request/data delete request each time, the gateway registration center may also directly send the latest address information to the data storage center after updating the address information each time, but this way will increase the coupling office of the system, and the embodiment of the present invention is not limited herein.
In a preferred embodiment, the distributed storage system is a distributed object storage system.
Specifically, the distributed object storage system is a commonly used one of the distributed storage systems.
Of course, besides the distributed object storage system, the distributed storage system may also be of other types, for example, a distributed file storage system, and the like, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, the step of prompting the user quota exhaustion to each gateway specifically includes:
judging whether the difference value of the sum of the current write-in amount of the user and the data variation corresponding to the data write-in request minus the quota is larger than the preset quota excess value of the user or not;
if not, executing the data writing request;
and if so, prompting each gateway that the user quota is used up.
In particular, considering that, when designing a quota, it is not possible to allocate all storage resources to all users in the form of a quota, moreover, some users can really have some quota excess values under the condition of higher importance level, that is, the write quantity of the user can exceed the preset quota excess value, therefore, the method and the device can judge whether the data writing request can cause the writing quantity of the user to exceed the quota plus the preset quota excess value or not in the judgment, when the time is exceeded, the data writing request is refused to be executed and all gateways are prompted, and under the condition that the quota is set, the 'quota' of the user can be conveniently adjusted by setting the preset quota excess value of the user in the data storage center, so that the flexibility of quota management is increased, and the user experience is further improved.
The preset quota excess value may be set autonomously, and the embodiment of the present invention is not limited herein.
