Description

Cache data cleaning method and device, computing equipment and storage medium

Technical Field

The present invention relates to the field of cache technologies, and in particular, to a method, an apparatus, a computing device, and a storage medium for cleaning cache data.

Background

Caching is a primary means of improving the performance of a web site or application, and can avoid repeated creation, processing, and transmission of data. However, since the cached data is simply a snapshot of the actual data, the original cached data becomes stale once the data source is modified. Therefore, cleaning and updating are required for the cache data.

Currently, the difficulties of cleaning and updating the cache mainly include the following: (1) The cache content is generally scattered, a simple page interface request of a user may use a plurality of cached results, for example, for a vehicle model list, the name of a vehicle model and guidance price data may belong to one cache item, and the price reduction data may be another cache item; (2) Various caching modes, such as caching to a distributed system redis, caching to an application memory and the like; (3) With the advent of micro-service architecture, caches for the same piece of data may exist in different micro-services.

The existing method for cleaning and updating the Cache is usually to clean up the Cache data (such as the method for annotating the @ Cache) in Java code for each place, and the method is easy to understand, but is often complicated to implement, needs to write cleaning and updating codes for each place manually by modifying the source data, and has low efficiency. Specifically, the method faces complex system call, the logic is very complicated, and corresponding cleaning codes need to be developed every time a cache project is newly added; every time an application is added, the corresponding code for cleaning up the cache is also required to be added.

The computing device 100 includes one or more processors and one or more readable storage media storing program instructions that, when configured to be executed by the one or more processors, cause the computing device to perform the cache data cleaning method 200 in an embodiment of the invention.

According to one embodiment of the invention, a cache data cleaning apparatus 400 is deployed in a computing device 100, the cache data cleaning apparatus 400 being configured to perform the cache data cleaning method 200 according to the invention. The cache data cleaning apparatus 400 includes a plurality of program instructions for executing the cache data cleaning method 200 of the present invention, where the program instructions may instruct a processor to execute the cache data cleaning method 200 according to the present invention, so as to implement cleaning and updating of cache data by executing the cache data cleaning method 200 of the present invention.

FIG. 2 illustrates a flow diagram of a method 200 for flushing cached data according to one embodiment of the invention. FIG. 3 is a flow diagram of a method for flushing cached data according to one embodiment of the invention. The buffered data cleaning method 200 is adapted to be executed in a buffered data cleaning apparatus 400 of a computing device, such as the aforementioned computing device 100.

As shown in fig. 2 and 3, method 200 begins at step 210.

First, in step 210, in response to a request to acquire source data, it is determined whether a cache clean-up tag is included in the request before processing the request. Here, the cache clean up flag is a parameter to clean up the cache.

Specifically, before processing the request, whether the request contains a cache cleaning mark can be judged by a section-oriented programming mode.

In one embodiment, the computing devices are communicatively connected to clients, management daemons (management daemons of source data), respectively. It should be noted that, when a user needs to access source data, the client may request to obtain the source data from the computing device 100. When an operation to clean up cached data needs to be triggered, a developer may send a request with a cache clean up flag to computing device 100 in the management background.

In this embodiment, the computing device 100 may receive a request to obtain source data sent by a client before responding to the request to obtain source data, and may receive a request with a cache clean-up flag sent in the management background.

The source data refers to the most original data that can be stored in the database. Because the storage structure of the database may not be consistent with the structure exhibited by the client/application, processing and handling are often required when reading the source data, resulting in slow source data reading speeds. And by caching the source data, the access speed can be improved by reading the cached data. However, since the cache data is often inconsistent with the generation of the source data, deletion and update of the cache data are required.

If it is determined that the request includes a cache clean-up tag, step 220 is performed.

In step 220, the cache clean-up tag is recorded to the context of the processing request. Next, one or more processing functions required to process the request may be initiated.

In addition, if it is determined that the cache clean-up tag is not included in the request, the one or more processing functions required to process the request are directly started to be invoked.

Finally, in step 230, for each processing function with a cache annotation called by the processing request, the cache data corresponding to the source data is deleted before executing the processing function. Thus, the cleaning operation of the cache data is realized so as to update the cache data. After deleting the cache data corresponding to the source data, the processing function can be executed to complete the call of the processing function and update the cache data of the source data.

For executing all processing functions corresponding to the request, the step 230 is executed respectively, so that the processing of the request can be finished, and the cleaning and updating of the cache data of the source data can be realized.

Here, it should be further noted that before deleting the cache data corresponding to the source data, it may be determined whether the cache cleaning flag exists in the context of the processing request, and if the cache cleaning flag exists, the cache data corresponding to the source data is deleted. If the cache clean-up tag does not exist in the context of the processing request, the processing function described above may be performed directly.

In one embodiment, a cache key corresponding to source data may be computationally determined from the source data. And deleting the cache data corresponding to the cache key value, thereby deleting the cache data corresponding to the source data.

In one embodiment, in step 230, for each processing function called by a processing request, a determination is first made as to whether a cache annotation exists in the processing function before the processing function is executed. Here, the Cache annotation is, for example, an @ Cache or an @ cached annotation.

If the processing function has the cache annotation, the processing function is determined to be the processing function with the cache annotation, and at the moment, whether the context of the processing request has the cache cleaning mark is further judged. And if the context of the processing request is determined to have the cache cleaning mark, deleting the cache data corresponding to the source data.

It should also be noted that before performing the method 200 of the present invention, a Cache annotation (e.g., an @ Cache or @ cached annotation) may be added in advance to each processing function corresponding to a processing request (i.e., a request to obtain source data). Here, the processing function, namely: and for the source data needing to be cached, acquiring a function needing to be called when the source data is acquired.

After the execution of the processing function described above (with cache annotation) the re-caching of the source data may be achieved. Specifically, by executing the processing function with the cache annotation, new cache data corresponding to the source data can be determined, and the new cache data corresponding to the source data is stored in the cache, so that the cache data of the source data is updated.

In one embodiment, when executing the processing function, it is also determined whether a third party service interface needs to be invoked.

If the third party service interface needs to be called, the cache cleaning mark is automatically added into the third party request parameter, and the third party service interface is called based on the third party request parameter after the cache cleaning mark is added. If the third party service interface is not required to be called, the processing function is continued to be executed.

In addition, while continuing to execute the processing function, it is further determined whether other processing functions need to be called, and if so, logic similar to that of step 230 is executed for the other processing functions.

It should be noted that, according to the above embodiment of the present invention, when the third party service interface needs to be invoked, the cache cleaning flag is automatically added to the third party request parameter, so that cleaning and updating of the cache data can be implemented for the cross-application scenario.

It should be noted that, for each processing function with a cache annotation called by the processing request, the present invention implements cleaning and updating of the cache data by executing the above step 230, until executing the call of all the processing functions with the cache annotation to complete the processing of the request, and implement unified cleaning and updating of all the cache data on the request link.

Fig. 4 shows a schematic diagram of a buffered data cleaning device 400 according to an embodiment of the present invention. The cache data cleaning apparatus 400 resides in the computing device 100. The cache data cleaning apparatus 400 may be configured to perform the cache data cleaning method 200 of the present invention.

As shown in fig. 4, the cache data cleaning apparatus 400 includes a judging module 410, a recording module 420, and an executing module 430, which are sequentially connected in communication.

The determining module 410 may determine, in response to a request for obtaining source data, whether the request includes a cache cleaning flag. If a cache clean-up tag is included, the logging module 420 may log the cache clean-up tag to the context that handled the request. The execution module may delete the cached data corresponding to the source data for each processing function with a cache annotation that processes the request call, and execute the processing function.

It should be noted that the determining module 410 is configured to perform the foregoing step 210, the recording module 420 is configured to perform the foregoing step 220, and the executing module 430 is configured to perform the foregoing step 230. Here, the specific execution logic of the determining module 410, the recording module 420, and the executing module 430 may be referred to the descriptions of the steps 210 to 230 in the foregoing method 200, and will not be repeated here.

According to the cache data cleaning method 200 of the present invention, when a request containing a cache cleaning mark is received, the cache cleaning mark in the request is recorded to the context of the processing request, in the process of processing the request, for each processing function with a cache annotation called by the processing request, the cache data corresponding to the source data is deleted, and the processing function is executed to update the cache data of the source data until the execution completes the call of all the processing functions with the cache annotation, so as to complete the processing of the request. Therefore, in the request processing process, the method and the device can realize automatic cleaning and updating of the cache data of the source data based on each called processing function, the cleaning process of the cache data is simpler and more efficient, and unified cleaning and updating of all the cache data on the request link are realized.
