Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Fig. 1 is a flowchart of a data storage method provided by some embodiments of the present disclosure. As shown in FIG. 1, in some embodiments of the present disclosure, a data storage method includes steps S101-S104. It should be noted that the data storage method is performed by a storage server capable of implementing a data storage function.
S101: and receiving a write request, wherein the write request comprises data to be written and information of a user account.
S102: based on the information of the user account, the capacity of the remaining space in the first storage space bound with the user account is determined.
The write request is a request for writing data into the storage server, which is transmitted from the user terminal having the write authority. The write request includes data to be written and information of the user account. The first storage space is a storage space purchased by a user and used for storing business data. The first storage space is bound to a user account.
In some embodiments of the present disclosure, the storage server may store information of the user account, a capacity of the first storage space bound to the user account, and a capacity of a used space in the first storage space in advance. After obtaining the information of the user account, the storage server inquires the capacity of the first storage space and the capacity of the used space based on the information of the user account, and determines the capacity of the remaining space according to the capacity of the first storage space and the capacity of the used space.
S103: and responding to the data volume of the data to be written being larger than the capacity of the residual space, and allocating a second storage space for the user account.
S104: at least part of the data to be written is written into the second storage space.
After obtaining the capacity of the remaining space in the first storage space, the storage server compares the data amount of the data to be written with the size of the capacity of the remaining space.
And if the data volume of the data to be written is larger than the capacity of the residual space, determining that the data to be written cannot be completely stored in the first storage space. In this case, the storage server allocates a second storage space for the user account, and writes at least part of the data to be written into the second storage space, so as to implement storage of the data to be written.
And if the data quantity of the data to be written is less than the capacity of the residual space, determining that the data to be written can still be stored in the first storage space. In this case, the entire data to be written is directly stored into the first storage space.
According to the data storage method provided by the embodiment of the disclosure, after the write-in request is obtained, the capacity of the first storage space bound with the user account is determined according to the information of the user account in the write-in request, and under the condition that the data volume of the data to be written in is larger than the remaining space capacity of the first storage space bound with the user account, the user account allocates the second storage space for storing the data, and at least part of the data is stored in the second storage space, so that the problem that the data to be written in cannot be stored due to the fact that the capacity of the first storage space is insufficient is avoided.
In some embodiments of the present disclosure, allocating the second storage space for the user account in step S103 may specifically include steps S1031 to S1032.
S1031: and determining the allocation capacity according to the data volume of the data to be written.
S1032: and allocating a second storage space for the user account according to the allocated capacity.
In a specific implementation, the step S1031 may determine the allocation capacity according to the data amount of the data in the following two cases.
In the first case, the storage server may use the amount of data to be written as the allocated capacity. In this case, the storage capacity of the second storage space is the same as the data amount of the data to be written. Correspondingly, the storage server may directly write all the data to be written into the second storage space when executing step S104.
In the second case, the storage server may calculate a difference between the data amount of the data to be written and the remaining space capacity, and take the difference as the allocated capacity. In this case, the storage capacity of the second storage space is smaller than the data amount of the data to be written, and the storage server writes only a part of the data to be written into the second storage space.
In the foregoing embodiment, the storage server allocates the second storage space to the user account according to the data volume of the data to be written. In some other disclosed embodiments, step S103 may further allocate a second storage space for the user account according to a preset capacity limit in the storage server.
Fig. 2 is a flowchart of a data storage method according to another embodiment of the present disclosure. As shown in FIG. 2, in some other embodiments of the present disclosure, a data storage method includes steps S201-S206.
S201: receiving a write request, wherein the write request comprises data to be written and information of a user account;
s202: determining the capacity of the residual space in the first storage space bound with the user account based on the information of the user account;
s203: judging whether the data volume of the data to be written is larger than the capacity of the residual space; if yes, executing steps S204 and S205; if not, go to S206.
S204: and allocating a second storage space for the user account, and writing at least part of the data to be written into the second storage space.
S205: and sending a first capacity expansion prompt to the management terminal, wherein the first capacity expansion prompt comprises information that the capacity of the first storage space is insufficient.
S206: and writing the data into the first storage space.
In the embodiment of the present disclosure, the specific implementation process of steps S201 to S204 may refer to the description of steps S101 to S104, and the following mainly analyzes steps S205 and S206.
In the embodiment of the present disclosure, the management terminal is a terminal for the capacity of the first storage space bound with the user account.
The storage server may determine that the first storage space capacity bound to the user account is insufficient if the data amount of the data to be written is greater than the capacity of the remaining space. At this time, the storage server generates a first capacity expansion prompt, adds the information that the capacity of the first storage space is insufficient to the first capacity expansion prompt, and sends the first capacity expansion prompt to the management terminal so as to prompt the management terminal to expand the capacity of the first storage space.
In some embodiments of the present disclosure, the second storage space may be a temporary storage space allocated for a user account. The second storage space has a preset life cycle (for example, it may be a week or a month), and after the storage duration of the second storage space reaches the preset life cycle, the second storage space will be recovered by the storage server, and the data stored in the second storage space will be deleted.
In order to prompt the user to expand the capacity of the first storage space as soon as possible, the first capacity expansion prompt sent to the user may further include information prompting the user that part of the data is only temporarily stored in the second storage space, so as to inform the user that there is a risk of losing the data when the first storage space is not expanded in time.
In the embodiment of the present disclosure, if the data amount of the data to be written is smaller than the capacity of the remaining space, it indicates that the first storage space can also store the data to be written, and the data to be written may be directly written into the first storage space.
In some embodiments of the present disclosure, the data storage method may further include steps S207-S208 before performing step S205, in addition to the aforementioned steps S201-S206.
S207: historical change data of the remaining space capacity of the first storage space is acquired.
S208: based on the historical change data, a recommended extended capacity is determined.
On the basis that the data storage method includes steps S207 and S208, step S205 may include step S2051: and adding the recommended expanded capacity into the first capacity expansion prompt and sending the first capacity expansion prompt to the management terminal.
By adopting the method provided by the embodiment of the disclosure, the storage server can calculate the recommended capacity expansion capacity based on the historical change data of the capacity of the residual space in the first storage space and send the recommended capacity expansion capacity to the management terminal, so that the management terminal can display and output the recommended capacity expansion capacity, and then a reference is provided for the user to expand the capacity of the first storage space.
In some embodiments of the present disclosure, step S205 may further include, in addition to the aforementioned step S2051, step S2052: and adding the historical change data into the first capacity expansion prompt and sending the first capacity expansion prompt to the management terminal.
The historical change data is added in the first capacity expansion prompt and sent to the management terminal, so that the management terminal can output the historical change data, a user can know the change trend of the residual capacity in the first storage space according to the historical change data, and the expansion capacity is determined according to the change trend of the residual capacity in the first storage space.
In some embodiments of the present disclosure, after the foregoing step S205 is performed, the data storage method may further include steps S209 to S211.
S209: and receiving a capacity expansion instruction sent by the management terminal, wherein the capacity expansion instruction comprises information of the expansion capacity allocated to the first storage space.
S210: based on the information for expanding the capacity, the capacity of the first storage space is expanded.
After receiving the capacity expansion instruction sent by the management terminal, the storage server extracts the capacity expansion information in the expansion instruction, and modifies the capacity of the first storage space bound with the user account based on the capacity expansion information, so as to realize the capacity expansion of the first storage space.
S211: and transferring the data written into the second storage space to the first storage space with the expanded capacity.
After the capacity of the first storage space is expanded, the first storage space has enough residual capacity, and the data written into the second storage space can be transferred to the first storage space of the expanded capacity Huohu at the moment, so that the long-term storage of the data can be realized.
In some embodiments of the present disclosure, the method of storing data may further include, in addition to the aforementioned steps S201 to S211, a step S212 after the step S202: and sending a second capacity expansion prompt to the management terminal in response to the capacity of the residual space being smaller than a preset capacity threshold value so as to prompt the management terminal to expand the capacity of the first storage space.
The preset capacity threshold is a capacity threshold for determining whether the remaining space capacity in the first storage space is excessively small. If the residual space capacity in the first storage space is smaller than the capacity threshold, the residual space capacity is smaller, and at the moment, the storage server generates a second capacity expansion prompt to prompt the management terminal to expand the capacity of the first storage space in time, so that the problem that the normal storage service is influenced due to insufficient capacity is avoided.
In some embodiments of the present disclosure, before sending the second capacity expansion prompt to the management terminal, the recommended expansion capacity may be further calculated based on historical change data of the remaining capacity in the first storage space, and the recommended expansion capacity is added in the second capacity expansion prompt and sent to the management terminal; in some embodiments of the present disclosure, the storage server may further add the change trend of the remaining capacity in a second capacity expansion prompt to be sent to the management terminal, so that the management terminal outputs the historical change data, and then the user can know the change trend of the capacity of the first storage space according to the historical change data.
