Abstract
Description

[0002] With the gradual increase in the access volume between the user side and the client side in various aviation fuel systems, each system application needs to support a larger number of concurrencies. Therefore, the performance of caching devices has received increasing attention. To adapt to the gradually increasing concurrency and the gradually improving user requirements, it is necessary to improve the speed and efficiency of the system application in responding to user requests. Therefore, while being able to cache data information, it is also necessary to improve the hit rate of the cache area of the caching device. The hit rate means that when the target data stored in advance needs to be retrieved again, the possibility of the target data existing in the cache area is greater, so that frequent retrieval of the target data from the data persistence layer can be avoided.
[0003] In the prior art, a storage strategy adapted to the storage area is set in advance according to the usage scenario. When there is data to be cached, the storage strategy is used for caching. However, due to factors such as the diversification of data types, the change of scenarios during the operation process, and the expansion of system application functions, the pre-set caching strategy is very likely to be no longer applicable to the subsequent data to be cached. Therefore, the hit rate of the cache area will be reduced, and the performance of the caching device will be reduced. Therefore, how to improve the hit rate of the cache area and the performance of the caching device is a technical problem that those skilled in the art need to solve currently.

Obviously, the described embodiments are only some, rather than all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by those of ordinary skill in the art without creative efforts belongs to the scope of protection of the present application.
[0040] Figure 1 Flowchart of a data caching method provided by an embodiment of the present invention. As Figure 1 shown, a data caching method includes:
[0041] S10: Predetermine multiple cache sub-regions in the buffer according to different cache topics, and set corresponding storage policies for each cache sub-region respectively.
[0042] Specifically, predetermine multiple different cache topics, including the number of cache topics and specific type information of cache topics, etc., and then set multiple cache sub-regions in the buffer according to the number of cache topics. The cache sub-regions need to cover all
[0043] For some caching topics, the total capacity of the cache sub - regions needs to be less than or equal to the total capacity of the cache region. Additionally, the storage space sizes of the cache sub - regions can be the same, or can be set according to the corresponding caching topics. The process of allocating the storage space sizes can be allocated according to the caching topics or according to a ratio. This embodiment does not limit this.
[0044] After setting up multiple cache sub - regions according to different caching topics, corresponding storage policies are set for each cache sub - region respectively. It can be understood that common storage policies include the First - In - First - Out (FIFO) policy, that is, clearing the data information that was cached earliest; the Least - Frequently - Used (LFU) policy, which clears the data information with fewer usage times according to the usage times of the data information; and the Least - Recently - Used (LRU) policy, which clears the data information with the farthest usage timestamp according to the timestamp of the last use of the data information. It should be noted that in this embodiment, generally, one storage policy is set corresponding to one cache sub - region to avoid duplicate storage or even storage chaos caused by multiple storage policies during the data caching process.
[0045] S20: When there is data to be cached, obtain the data topic of the data to be cached.
[0046] When it is detected that there is currently data to be cached, that is, when it is detected that there is data information that needs to be cached,
[0047] Obtain the data topic of the data to be cached. It can be understood that each data information has its corresponding topic. Therefore, when it is determined that there is data to be cached, obtain the data topic of the data to be cached.
[0048] S30: Select the target cache sub - region using the correspondence between the data topic and the cache topic.
[0049] It can be understood that after obtaining the data topic of the data to be cached, according to the correspondence between the data topic and the cache topic, select the target cache sub - region corresponding to the data topic. The target cache sub - region is the cache sub - region used to store the data to be cached. Generally, one data to be cached corresponds to one target cache sub - region. It should be noted that the correspondence between the data topic and the cache topic can be the same relationship, that is, select the cache topic that is the same as the data topic, and use the cache sub - region corresponding to this cache topic as the target cache sub - region.
[0050] S40: Store the data to be cached using the storage policy corresponding to the target cache sub - region.
[0051] In a physical system, since storage policies corresponding to each cache sub-region have been set previously, after obtaining the target cache sub-region by using the correspondence between the data topic and the cache topic, the storage policy of the target cache sub-region is used to perform a caching operation on the information to be cached, so as to cache the data to be cached in the target cache sub-region.
[0052] A data caching method provided by an embodiment of the present invention includes: pre-setting a plurality of cache sub-regions in a buffer according to different cache topics, and respectively setting corresponding storage policies for each cache sub-region; when there is data to be cached, obtaining the data topic of the data to be cached; and then selecting a target cache sub-region by using the correspondence between the data topic and the cache topic.
[0053] Thereby, the data to be cached is stored by using the storage policy corresponding to the target cache sub-region. Since the data to be cached is cached in the cache sub-region corresponding to the data topic of the data to be cached, the possibility that the data information cached in each cache sub-region is the target data that needs to be used again later is greater, that is, the possibility that the target data is stored in the buffer is greater. Therefore, the hit rate of the buffer is improved, and the performance of the caching device is enhanced.
[0054] Figure 2 FIG. is a flowchart of another data caching method provided by an embodiment of the present invention. On the basis of the above embodiment, this embodiment further explains and optimizes the technical solution. Specifically, the step of obtaining the data to be cached specifically includes:
[0055] S21: Obtain a user request;
[0056] S22: Determine whether the data information corresponding to the user request exists in the cache sub-region;
[0057] S23: If not, obtain the data information corresponding to the user request from the data persistence layer to obtain the data to be cached.
[0058] In this embodiment, further considering the source of the data information cached in the buffer. Specifically, when a user request is obtained, it is determined whether the data information corresponding to the user request exists in the cache sub-region. If it exists, it means that the data information can be directly obtained from the buffer, so there is no need to perform a caching operation; otherwise, it is necessary to obtain the data information corresponding to the user request from the data persistence layer according to the user request to obtain the data to be cached, and then store it in the corresponding cache sub-region by using the correspondence between the data topic of the obtained data to be cached and the cache topic. It should be noted that the data persistence layer is a device for storing data, such as a disk or a database, etc.
[0059] It can be seen that the data caching method provided by this embodiment can cache the data to be cached obtained through multiple channels, improving the practicability.
[0060] Based on the above embodiments, the technical solution is further described and optimized in this embodiment. Specifically, when there is no target cache sub-region corresponding to the data topic in the cache sub-region, the method further includes:
[0061] Add a target cache sub-region corresponding to the data topic of the data to be cached in the cache area and set the corresponding storage policy, and enter the step of storing the data to be cached using the storage policy corresponding to the target cache sub-region.
[0062] Specifically, considering that there may be a situation where there is no target cache sub-region corresponding to the data topic of the data to be cached obtained, in order to facilitate the subsequent use of the data to be cached, in this embodiment, a target cache sub-region corresponding to the data topic of the data to be cached is further added in the cache area, and a corresponding cache policy is set for this cache sub-region, and then the data to be cached is cached in this target cache sub-region using the cache policy.
[0063] The data caching method provided in this embodiment, compared with the method of discarding the data to be cached or storing it in the data persistence layer when there is no cache topic corresponding to the data topic of the data to be cached in the cache sub-region, this method adds a target cache sub-region for the data to be cached and caches the data to be cached in this target cache sub-region using the corresponding storage policy, thereby improving the scalability of the cache area and making it more convenient to obtain the data to be cached subsequently.
[0064] Based on the above embodiments, the technical solution is further described and optimized in this embodiment. Specifically, the method further includes:
[0065] Count the number of accesses to each cache sub-region within a preset time;
[0066] When there is a target cache sub-partition with the number of accesses less than the preset number threshold, clear the cache topic of the target cache sub-partition and the cache content in the target cache sub-partition.
[0067] Specifically, in this embodiment, a counter is set for each cache sub-region in advance. When there is an operation to access the data information in the cache sub-region, the count value of the counter corresponding to the cache sub-region is incremented by 1, and then the access times of each cache sub-region within a preset time are counted. When the preset time is reached, the access times of each cache sub-region are compared with a preset number threshold. When there is a target cache sub-region with access times less than the preset number threshold, it indicates that the data information in this cache sub-region is accessed less frequently in the later stage. Therefore, the cache topic and the cache content in the target cache sub-region are cleared. It should be noted that in this embodiment, the preset number threshold can be set to 0, or can be set to other values according to actual needs and actual operation experience.
[0068] It can be seen that the data caching method provided in this embodiment can further improve the hit rate of the cache area.
[0069] Based on the above embodiment, this embodiment further explains and optimizes the technical solution. Specifically, setting multiple cache sub-regions in the cache area according to different cache topics in advance includes:
[0070] Set multiple different cache topics in advance;
[0071] Classify different cache topics;
[0072] Set multiple cache sub-regions in the cache area, and set the cache topics belonging to the same class in the same cache sub-region.
[0073] Specifically, set multiple different cache topics in advance, and then classify different cache topics. Specifically, two or more cache topics can be classified into one class, and then the cache topics belonging to the same class are set in the same cache sub-region, that is, one cache sub-region can subscribe to multiple cache topics belonging to the same class. By setting multiple cache topics in the same cache sub-region, that is, setting multiple cache topics of the same class for the same cache sub-region, while ensuring that the data to be cached corresponding to multiple types of data topics can be cached, the number of cache sub-regions is reduced, making the cache area more concise.
[0074] As a preferred implementation, the cache topic is specifically a topic set according to the task type.
[0075] In specific implementation, cache topics can be set according to task types. For example, cache topics can be set according to long tasks and short tasks. More specifically, cache topics can be set according to the task types where the data to be cached needs to be cached in a logical pool or a logical volume. In other embodiments, cache topics can also be set in other ways, such as according to data types, data sizes, or data formats. This embodiment does not make any limitations in this regard. Since the storage policies corresponding to different task types vary greatly, by setting cache topics according to task types in this embodiment, the hit rate of the cache area can be improved.
[0076] The above has described in detail the embodiments of a data caching method provided by the present invention. The present invention also provides a data caching device, a device, and a computer-readable storage medium corresponding to this method.
