Detailed Description
In order to solve the following problems in the prior art: in the prior art, a large number of read-write operations are caused by traversing the whole file volume, and the efficiency of managing and deleting files is too low, which affects the use experience of users. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
A first embodiment of the present invention provides a method for managing a file volume, which is applied to an object storage system, and a flowchart of the method is shown in fig. 1, and specifically includes steps S101 to S103:
s101, setting types of a plurality of file volumes, and determining corresponding expiration time of each type of file volume, wherein the expiration times of different types of file volumes are different.
In the object storage system, a plurality of file volumes are set, different types are set for the file volumes respectively, the file volumes of different types are used for storing files to be stored with different expiration times, the corresponding expiration time is determined according to the type of each file volume, and the expiration times of the file volumes of different types are different.
S102, when the file is stored, the file to be stored is stored into the file volume of the corresponding type according to the expiration time of the file to be stored.
Since the number of file volumes is set according to the type, when storing the file, the file should be stored in the file volume of the corresponding type according to the expiration time of the file to be stored. Specifically, files to be stored with the same expiration time are stored in the same file volume, so that all files in the file volume are in an expiration state when the file volume is subsequently managed or deleted.
And S103, deleting the file volume according to the expiration time of the file volume.
When managing file volumes, the object storage system deletes file volumes according to different expiration times of different types of file volumes. When the state of the file volume meets the deletion condition, all files stored in the file volume are proved to reach the expiration time, so that traversing operation on each file volume is not needed to screen the files needing to be deleted, and only the whole corresponding expired file volume is deleted.
The file deletion method has the advantages that the types of the file volumes are set, the files to be stored are stored into the file volumes of the corresponding types according to different expiration times of the files, when the files need to be deleted, the whole file volumes can be deleted only according to the expiration time of the file volumes of the corresponding types, operations such as traversing the expiration times of all the stored files in the file volumes, then transferring, deleting and the like are not needed, the read-write times of the magnetic disk are greatly reduced, and the management deletion efficiency and the use experience of a user are improved.
A second embodiment of the present invention provides a method for managing a file volume, which is applied to an object storage system, and a flowchart thereof is shown in fig. 2, and specifically includes steps S201 to S205:
s201, setting a plurality of time periods.
S202, according to the plurality of time periods, a plurality of file volume types which are in one-to-one correspondence with each time period in the plurality of time periods are set.
The expiration time of files to be stored typically varies from a few days to tens of days, and there may be longer term or permanently valid files. Therefore, in order to store files of different expiration times, when setting a plurality of types of file volumes, a plurality of time periods may be set first, and the time periods should be consecutive but have no time intersection with each other. And then setting corresponding file volume types according to time periods, wherein each time period has a corresponding file volume type, and the file volume of the type is used for storing files to be stored, the expiration time of which falls within the time period.
S203, determining the expiration time of the file volume type corresponding to each time slot according to the time upper limit of each time slot in the plurality of time slots.
In order to manage and delete a file volume, after a plurality of types of file volumes are set, the expiration time corresponding to each type of file volume needs to be determined, so that the file volume can be managed according to the expiration time of the file volume. Since each file volume type corresponds to a set time period, and the expiration time of the saved file does not exceed the time limit of the time period, the upper limit of each time period should be used as the expiration time of the file volume of the corresponding type. For example, first, four time periods are set, which are 0 to 7 days, 7 to 15 days, 15 to 30 days, 30 to 90 days and more than 90 days, respectively, then five types of file volumes are correspondingly set, the first type of file volume is used for storing files with expiration time greater than 0 day and less than or equal to 7 days, and the expiration time of the first type of file volume is 7 days; the second type file volume is used for storing files with expiration time of more than 7 days and less than or equal to 15 days, and the expiration time of the second type file volume is 15 days; the third type file volume is used for storing files with expiration time of more than 15 days and less than or equal to 30 days, and the expiration time of the third type file volume is 30 days; the fourth type file volume is used for storing files with expiration time of more than 30 days and less than or equal to 90 days, and the expiration time of the fourth type file volume is 90 days; the fifth type file volume is used for storing files with expiration time larger than 90 days, and the fifth type file volume does not set the expiration time. It should be understood that in the process of setting the type of the file volume, a file volume with a time limit being infinite should be always included, such as a file volume of the fifth type, for storing all files with expiration time exceeding 90 days, and since there is no time limit, the expiration time of the file volume of the type is not set.
It should be understood that the above time period and file volume type dividing method are not limited to the above time nodes, and may be flexibly set according to the expiration time and the number of files to be stored in actual use.
And S204, when the file is stored, storing the file to be stored into the file volume of the corresponding type according to the expiration time of the file to be stored.
Since the number of file volumes is set according to the type, when storing the file, the file should be stored in the file volume of the corresponding type according to the expiration time of the file to be stored. Specifically, files to be stored with the same expiration time are stored in the same file volume, so that all files in the file volume are in an expiration state when the file volume is subsequently managed or deleted.
And S205, deleting the file volume according to the expiration time of the file volume.
When managing file volumes, the object storage system deletes file volumes according to different expiration times of different types of file volumes. When the state of the file volume meets the deletion condition, all files stored in the file volume are proved to reach the expiration time, so that traversing operation on each file volume is not needed to screen the files needing to be deleted, and only the whole corresponding expired file volume is deleted.
The file deletion method has the advantages that the types of the file volumes are set, the files to be stored are stored into the file volumes of the corresponding types according to different expiration times of the files, when the files need to be deleted, the whole file volumes can be deleted only according to the expiration time of the file volumes of the corresponding types, operations such as traversing the expiration times of all the stored files in the file volumes, then transferring, deleting and the like are not needed, the read-write times of the magnetic disk are greatly reduced, and the management deletion efficiency and the use experience of a user are improved.
A third embodiment of the present invention provides a method for managing a file volume, which is applied to an object storage system, and a flowchart thereof is shown in fig. 3, and specifically includes steps S301 to S306:
s301, a plurality of time periods are set.
S302, according to a plurality of time periods, a plurality of file volume types which are in one-to-one correspondence with each time period in the plurality of time periods are set.
The expiration time of files to be stored typically varies from a few days to tens of days, and there may be longer term or permanently valid files. Therefore, in order to store files of different expiration times, when setting a plurality of types of file volumes, a plurality of time periods may be set first, and the time periods should be consecutive but have no time intersection with each other. And then setting corresponding file volume types according to time periods, wherein each time period has a corresponding file volume type, and the file volume of the type is used for storing files to be stored, the expiration time of which falls within the time period.
S303, determining the expiration time of the file volume type corresponding to each time period according to the time upper limit of each time period in the plurality of time periods.
In order to manage and delete a file volume, after a plurality of types of file volumes are set, the expiration time corresponding to each type of file volume needs to be determined, so that the file volume can be managed according to the expiration time of the file volume. Since each file volume type corresponds to a set time period, and the expiration time of the saved file does not exceed the time limit of the time period, the upper limit of each time period should be used as the expiration time of the file volume of the corresponding type.
S304, determining the time period to which the expiration time of the file to be stored belongs.
S305, storing the file to be stored into the file volume of the type corresponding to the time period according to the time period to which the expiration time of the file to be stored belongs.
When storing files, firstly acquiring the expiration time of the files to be stored, determining the time period to which the files to be stored belong according to the expiration time of the files to be stored and the preset time period, and then storing the files to be stored in the file volumes of the types corresponding to the time period. For example, the expiration time of the file a to be stored is 20 days, and the time period to which the file a should be attributed is 15 days to 30 days, that is, the file a should be stored in the third type file volume.
And S306, deleting the file volume according to the expiration time of the file volume.
When managing file volumes, the object storage system deletes file volumes according to different expiration times of different types of file volumes. When the state of the file volume meets the deletion condition, all files stored in the file volume are proved to reach the expiration time, so that traversing operation is not required to be carried out on each file volume to screen the files needing to be deleted, and only the whole corresponding expired file volume is deleted.
According to the embodiment, the files to be stored are classified and stored according to the expiration time, the files with the expiration times belonging to the same time period are stored in the same type of file volume, and it is guaranteed that all the files stored in the file volume are in the expiration state when the expiration time of the file volume reaches, so that the same deletion management can be realized, the read-write times of a disk are reduced, and the deletion management efficiency and the use experience of a user are improved.
A fourth embodiment of the present invention provides a method for managing a file volume, which is applied to an object storage system, and a flowchart of the method is shown in fig. 4, and specifically includes steps S401 to S404:
s401, setting types of a plurality of file volumes, and determining corresponding expiration time of each type of file volume, wherein the expiration times of different types of file volumes are different.
In the object storage system, a plurality of file volumes are set, different types are set for the file volumes respectively, the file volumes of different types are used for storing files to be stored with different expiration times, the corresponding expiration time is determined according to the type of each file volume, and the expiration times of the file volumes of different types are different.
S402, when the files are stored, the files to be stored are stored into the file volumes of the corresponding types according to the expiration time of the files to be stored.
Since the number of file volumes is set according to the type, when storing the file, the file should be stored in the file volume of the corresponding type according to the expiration time of the file to be stored. Specifically, files to be stored with the same expiration time are stored in the same file volume, so that all files in the file volume are in an expiration state when the file volume is subsequently managed or deleted.
S403, determining the time difference between the last modification time and the current time of the file volume.
S404, deleting the file volume when the time difference is larger than the expiration time of the file volume.
In this embodiment, the object storage system continuously stores files in a certain type of file volume, so that the modification time of the file volume is continuously changed, when a deletion operation is required, it is first required to determine a time difference between the last modification time of the file volume and the current time, and determine whether the time difference is greater than the expiration time of the file volume, and when the time difference is greater than the expiration time of the file volume, it is proved that the last written file in the file volume has expired, and then other files stored in the file volume before the file have also expired, and at this time, the file volume may be deleted, together with the expired file in the file volume. For example, if the current time is 18 days in 2018, 4 months, and the last modification time of the first-type file volume is 10 days in 2018, 4 months, and 10 days in 2018, the time difference between the last modification time of the first-type file volume and the current time is 8 days, and the expiration time of the first-type file volume is already exceeded by 7 days, at this time, all files in the first-type file volume are necessarily in an expiration state, and the first-type file volume is deleted.
Alternatively, for a file volume with an expiration time not set, such as a fifth-type file volume, a default management policy may be adopted, that is, all files in the fifth-type file volume are traversed, and whether each file is expired or not is determined, and for an expired file, the expired file may be transferred to another file volume, and after the traversal and the transfer are completed, the file volume is deleted. Although traversal operation is required to be performed on the fifth-type file volume, a considerable part of files are already stored in other four types of file volumes, only files with expiration time longer than 90 days are stored in the fifth-type file volume, the number of traversed files is reduced, the expiration time of the files stored in the fifth-type file volume is long, and deletion is not required to be performed too frequently, so that frequent read-write operation is not performed, and efficiency is further influenced.
It should be understood that after a file volume of a certain type is deleted, in order to ensure that a file subsequently stored in the file volume of the certain type can be normally stored, a file volume of the certain type should be reset after the file volume of the original type is deleted, and the expiration time of the newly set file volume of the certain type is the same as that of the original file volume.
According to the embodiment, the file volume is deleted through the last modification time of the file volume and the expiration time of the file volume, and all files in the file volume are deleted along with the deletion of the file volume, so that operations such as traversal and transfer of the files in the file volume are not needed, the read-write times of a disk are reduced, and the efficiency of managing deletion and the use experience of a user are improved.
A fifth embodiment of the present invention provides a file volume management apparatus provided in an object storage system, the apparatus having a configuration as shown in fig. 5, and including:
the setting module 10 is configured to set types of a plurality of file volumes, and determine expiration times corresponding to the file volumes of each type, where the expiration times of different types of file volumes are different; the storage module 20 is coupled with the setting module 10 and is used for storing the files to be stored into the file volumes of the corresponding types according to the expiration time of the files to be stored when the files are stored; and the deleting module 30 is coupled with the storage module 20 and is used for deleting the file volume according to the expiration time of the file volume.
In the object storage system, a setting module 10 sets a plurality of file volumes, and sets different types for the plurality of file volumes, the different types of file volumes are used for storing files to be stored with different expiration times, and the corresponding expiration times of the file volumes are determined according to the types of the file volumes, and the expiration times of the different types of file volumes are different.
Specifically, since the expiration time of the file to be stored generally varies from several days to several tens of days, and there may be a file that is valid for a longer period or is permanently, the setting module 10 may set, when setting a plurality of file volumes, a plurality of time periods that should be consecutive but have no time intersection with each other first; then the setting module 10 sets the corresponding file volume type according to the time periods, each time period has a corresponding file volume type, and the file volume of the type is used for storing the file to be stored whose expiration time falls within the time period; in order to manage and delete a file volume, after a plurality of types of file volumes are set, the setting module 10 needs to determine the expiration time corresponding to each type of file volume, so as to facilitate subsequent management of the file volume according to the expiration time of the file volume. Because the type of each file volume corresponds to a set time period, and the expiration time of the stored files does not exceed the time limit of the time period, the upper limit of each time period should be used as the expiration time of the corresponding type file volume, and the expiration time is not set for the time period without the time limit.
Since a plurality of file volumes are set according to types, when storing a file, the storage module 20 stores the file into a file volume of a corresponding type according to the expiration time of the file to be stored. Specifically, the storage module 20 first obtains the expiration time of the file to be stored, determines the time period to which the file to be stored should belong according to the expiration time of the file to be stored in combination with a preset time period, and then stores the file to be stored into the file volume of the type corresponding to the time period, where the files to be stored with the same expiration time are stored into the same file volume, so as to ensure that all files in the file volume are in an expired state when the file volume is subsequently managed or deleted.
When managing the file volume, the deleting module 30 may delete the file volume according to different expiration times of different types of file volumes. When the state of the file volume meets the deletion condition, all files stored in the file volume are proved to reach the expiration time, so that traversing operation on each file volume is not needed to screen the files needing to be deleted, and only the files corresponding to the expiration time need to be deleted integrally. Specifically, the storage module 20 continuously stores files in a certain type of file volume, so that the modification time of the files is changed continuously, when a deletion operation needs to be performed, the deletion module 30 needs to first determine a time difference between the last modification time of the file volume and the current time, and determine whether the time difference is greater than the expiration time of the file volume, and in the case that the time difference is greater than the expiration time of the file volume, it is proved that the last written file in the file volume is expired, and then other files stored in the file volume before the file are also expired, and at this time, the deletion module 30 may delete the file volume together with the expired files in the file volume.
Alternatively, for a file volume for which the expiration time is not set, a default management policy may be adopted, that is, all files in the file volume are traversed, whether each file is expired or not is determined, and for an expired file, the file may be transferred to another file volume, and after the traversal and the transfer are completed, the other file volume is deleted. Although traversal operation is required to be performed on a file volume without setting the expiration time, as a considerable part of files are stored in other types of file volumes, the number of traversed files is reduced, the expiration time of the files stored in the file volume without setting the expiration time is long, and deletion is not required to be performed too frequently, so that frequent read-write operation is not performed, and further efficiency is affected.
It should be understood that after a file volume of a certain type is deleted, in order to ensure that a file subsequently stored in the file volume of the certain type can be normally stored, a file volume of the certain type should be reset after the file volume of the original type is deleted, and the expiration time of the newly set file volume of the certain type is the same as that of the original file volume.
The file deletion method has the advantages that the types of the file volumes are set, the files to be stored are stored into the file volumes of the corresponding types according to different expiration times of the files, when the files need to be deleted, the whole file volumes can be deleted only according to the expiration time of the file volumes of the corresponding types, operations such as traversing the expiration times of all the stored files in the file volumes, then transferring, deleting and the like are not needed, the read-write times of the magnetic disk are greatly reduced, and the management deletion efficiency and the use experience of a user are improved.
