Detailed Description
In the technical scheme provided by the embodiment of the application, the incremental write-back is performed through the database in the memory, so that the data volume of the write-back of the database is reduced, the write-back time is shortened, the write-back performance is not influenced by the whole size of the database, the write-back requirement of high frequency is met, the technical problem that the write-back performance of the database is lower in the prior art is solved, and the write-back performance of the database is improved.
The following describes in detail the main implementation principles of the technical solution of the embodiments of the present application, the specific implementation manner and the corresponding beneficial effects.
Examples
Referring to fig. 1, an embodiment of the present application provides an information processing method, which is applied to write-back of a database. The database can be a personalized database of the user or a common database. The information processing method comprises the following steps:
s110: dividing a memory space for loading a database into N storage areas, wherein N is more than or equal to 2;
s120: checking the content data in the N blocks of storage areas to obtain a target storage area with modified content data;
s130: acquiring the ratio of the number M to the number N of the target storage areas;
s140: and if the ratio reaches a preset value, triggering an incremental write-back operation, and performing incremental write-back on the database in the memory based on the target content data in the target storage area.
In the implementation process, when the application program loads the database into the memory of the electronic device, the formats of the database loaded into the memory and the database in the hard disk file are kept the same, so that the database can be written back conveniently. And, after the database is loaded into the memory, S110 is performed to divide the memory space for loading the database into N storage areas, so that the data in each storage area is greatly reduced with respect to the overall data of the database. The embodiment does not limit the specific mode of dividing the memory space, randomly divides the memory space, equally divides the memory space, and divides the memory space in a mode of guaranteeing the integrity of each data. In order to facilitate recording and querying, the memory space of the loaded database is preferably equally divided. The size of each storage area can be 4K or 8K, excessive division can increase the write-back burden and increase the write-back of invalid data, and experiments show that the write-back performance is optimal when the size of each storage area is 4K or 8K.
After S110, S120 is performed to detect that the target storage area in which the obtained content data is modified. The detection of the target storage area may be performed by comparing content data, or may be performed by modifying the identification detection. To reduce the amount of detection effort, each block of storage area may be marked after the storage area is divided for a first identification, e.g. a bit is used to indicate the state of the content data therein, and an initial value of 0 indicates that it has not been modified. When the content data in a certain block storage area is modified, such as deleted, replaced, updated, etc., the identity of the block storage area is modified to a second identity, i.e., a modification identity, such as changing a bit representing the status of its content data from 0 to 1. When the target storage area is obtained through detection, the identification of each storage area can be detected, and the content data in the storage area identified as the second identification is modified, so that the storage area identified as the second identification can be directly used as the target storage area, the detection workload is greatly reduced, and the detection efficiency is improved.
Further, after the target storage area is obtained, S130 is performed to obtain a ratio of the number M of target storage areas to the total number N of storage areas for the cache database. And then, continuing to execute S140, if the ratio of M to N reaches a preset value, triggering incremental write-back operation, and performing incremental write-back on the database in the memory based on the target content data in the target storage area. Specifically, in the incremental write-back process, the database data write-back of the non-target storage area in the memory is skipped, and the target data in the target storage area is written back to the position corresponding to the database file in the hard disk.
In the implementation process, the preset value can be set to 8%, 10% and 15% equivalent, and can be specifically set according to the size of each storage area, and the preset value is not suitable to be set too much to avoid increasing the workload of increment write-back each time. It should be noted that, when detecting multiple target storage areas, incremental write-back is triggered, unlike simply increasing the size of each storage area, simply increasing the size of each storage area will write back the same data once, and the small data storage area divides the target data content of multiple target storage areas to write back once, which can effectively reduce write-back of the same data, and simultaneously reduce write-back frequency, and further improve write-back performance. After the write-back is completed in S140, the embodiment further initializes the identifier of the N-block storage area in the memory to the first identifier, and returns to S120 to perform the next incremental write-back.
In the above embodiment, the memory space for loading the database is divided into N storage areas; detecting a target storage area in which the obtained content data changes; based on the target content data in the target storage area, incremental write-back is carried out on the database in the memory, so that the write-back data volume is greatly reduced, the write-back time is shortened, the write-back performance is not influenced by the whole size of the database, the write-back requirement of high frequency can be met, the technical problem of lower write-back performance of the database in the prior art is solved, and the write-back performance of the database is improved. Furthermore, the write-back performance of the database is improved by the incremental write-back method, so that the database can be written back more frequently, and the risk of losing data of the database is greatly reduced.
With respect to the foregoing embodiments, an information processing method is provided, and an information processing apparatus is correspondingly provided in an embodiment of the present application, referring to fig. 2, the apparatus includes:
the dividing unit 21 is used for dividing the memory space for loading the database into N storage areas, wherein N is more than or equal to 2;
a detection unit 22 for detecting a target storage area in which the obtained content data is modified;
a write-back unit 23, configured to obtain a ratio of the number M of the target storage areas to the number N of the target storage areas; and if the ratio reaches a preset value, triggering an incremental write-back operation, and performing incremental write-back on the database in the memory based on the target content data in the target storage area.
As an optional implementation manner, in the incremental write-back process, the write-back unit 23 may skip the write-back of the database data in the non-target storage area in the memory, and write back the target data in the target storage area to a location corresponding to the database file in the hard disk.
As an alternative embodiment, the apparatus may further include: an identification unit 24, configured to modify, when modifying content data in the memory space, an identification of a storage area where the modified content data is located from a first identification to a second identification; after the incremental write-back operation is completed, initializing the identification of the N-block storage area to the first identification. Accordingly, the detection unit 22 detects the identity of each storage area when detecting the acquisition target storage area, and acquires the storage area identified as the second identity as the target storage area.
As an alternative embodiment, the dividing unit 21 may divide the memory space of the loading database according to the size of each storage area 4K or 8K.
