Description
Technical Field
The invention belongs to computer processing systems, in particular to a processing system based on the internet or mobile internet, and particularly relates to a control method and a control device for caching dynamic time period information without repeatedly updating the information within a period of time.
Background
Computer processing systems have become increasingly popular and are used over a large area in a variety of industries. In the prior art, information is generally transmitted from one terminal to another terminal or from a server to a client. The information may be a variety of information, such as web page information, such as news, such as advertising information, and the like.
For information such as news, if the information is instant news, the information is usually transmitted instantly. However, instant news cannot be endless, so in a desktop client or a mobile terminal, in order to enrich news information in the terminal, some non-instant information is transmitted in addition to very instant news information, for example, in the afternoon, relatively important news of the morning is displayed on the client together. In such a case, when transmitting news information, it is also possible to distinguish between instant information and non-instant information. In some cases, important news information may be displayed for two consecutive days or a week.
The transmission of news information is repeated, and the transmission of other contents is more likely to be the case. For example, the update frequency may not be particularly high for advertising information, such as a week of ad spots purchased by some advertisers, but only one, in which case the advertising information is presented frequently at one client. In a typical communication mode, the same advertisement information may be transmitted from one terminal to another terminal or from a server to a client many times. Such a transmission is certainly not necessary.
The same is true for weather forecast information, which is generally common three days or a week in advance, and which is usually very accurate, so that after such weather information has been transmitted to the user terminal, there is no need to repeat the transmission.
Based on the idea, one-time transmission and multiple-time use are technical problems to be solved. But this presents another technical problem when is the last transmitted information updated? Is an update required?
The invention aims to provide a solution for judging whether information in a dynamic time period needs to be updated or not, thereby effectively managing the information in a cache.

fig. 2 is a schematic flowchart illustrating a method for controlling dynamic time period information caching according to a second embodiment of the present invention.
Detailed Description
In order to better and clearly show the technical scheme of the invention, the invention is further described with reference to the attached drawings.
The technical staff in the field understand that, aiming at the defects of the prior art, the invention discloses a method for caching dynamic time period information, which can effectively manage the pre-stored information in the cache.
Fig. 1 is a schematic flowchart illustrating a method for controlling dynamic time period information caching according to an embodiment of the present invention. Specifically, the process first advances to step S101 to determine whether target information exists in the cache. Those skilled in the art will understand that in the present embodiment, it is preferable to determine whether the required target information exists in the cache by querying information at a specific location in the cache. Furthermore, those skilled in the art understand that, as described in the subsequent steps, when the information in a database is copied to the cache of a client, the target information is managed through a linked list, a queue or a similar data structure, so as to facilitate retrieval, and such variations are within the protection scope of the present invention and are not described herein again.
In yet another variation, when the target information is copied from the database to the cache, a directory is already created, which records the identification of all target information, and by this identification, it can be determined which target information is used for which app or other computer software, so as to facilitate finding the target information. Further, the target information may be various information, and may be various information, not only one type of information, such as news information with different levels and priorities, weather information with different days, advertisement information with different advertisers, different types and different fields, and the like, which may be recorded in the directory. Furthermore, those skilled in the art understand that the directory may preferably further record a location where the target information is finally stored in the cache, for example, record the location through a pointer structure, and these variations are within the scope of the present invention and are not described herein again.
Then, step S102 is performed, and if the target information exists, the target information in the cache is used. Further, those skilled in the art understand that when a weather application (app) needs to display weather information of the second day and the third beijing city, it will preferably determine whether the query cache described in step S101 contains the weather information, and if such target information exists, the weather app directly copies the target information from the cache, and then may directly use the target information to display the needed weather information in the corresponding app.
Further, those skilled in the art understand that the information required by the weather app needs a clear identification, which the weather app can handle. In the invention, the information required by the weather app is acquired and is inquired in the cache correspondingly, so that the aim of the invention can be fulfilled. Furthermore, those skilled in the art understand that from today's perspective, the second piece of weather information may exist in the cache, but from yesterday's perspective, the second day weather information (i.e. the acquired weather information) may not exist in the cache, so the technical solution provided by the present invention can effectively manage these pieces of information, as described in the embodiment shown in fig. 2.
After the step S101, preferably, a step S103 may be further performed, and if the target information does not exist in the cache, the target information in the cache is updated. In one case, the target information is used for the first time, e.g., the mobile terminal is restarted after being powered off, and there is no information in the cache. For another example, if an application is first started, the cache preferably does not have target information corresponding to the application (app), and so on. However, it is also part of the system to be solved by the present invention, so that when there is no target information, the target information, for example, the weather information of the next day, is copied from the database and is adaptively stored in the cache, and as described above, necessary operations such as indexing are performed, thereby facilitating the search for the weather information.
Further, those skilled in the art will appreciate that, with the embodiment shown in fig. 1, an aspect of the present invention is implemented that when an information needs to be used, especially when such information is repeatedly used all the time and does not need to be updated all the time, first, whether such information exists in the cache is searched, and if so, the information is directly used. The method is very suitable for a weather program, a news client and an advertisement column, and part of contents in the application programs are not updated every moment, so that the contents which can be displayed but are not updated at any moment are stored in the cache and are directly called from the cache for use when needed, so that the efficiency of the application programs is improved, network transmission is reduced, and frequent writing operation of the cache is reduced.
In conjunction with the embodiment shown in fig. 1, it is preferable that the step of updating the target information in the cache (step S103) further includes the following steps: i. and updating the timestamp information and/or version number information and/or identification information corresponding to the target information.
Further, those skilled in the art understand that it is necessary to add some attributes to the target information in order to facilitate management of the target information. The attributes that can be applied from the management perspective of the database and the queue can be added to the embodiment, and these changes are within the protection scope of the present invention and will not be described herein. For example, the version number is added to the target information, so that the control device provided by the invention can manage the target information conveniently. For example, in a variation, the weather app sends required information to the control device, and the control device retrieves target information according to the version number information, so as to determine that part of information required by the weather app exists in the cache, and then returns the information to the weather app, thereby achieving the purpose of obtaining the target information from the cache. Similarly, the effect of implementing and managing the object of the present invention can be achieved through the timestamp and the identification information, which are not described herein again.
Fig. 2 is a schematic flowchart illustrating a method for controlling dynamic time period information caching according to a second embodiment of the present invention. First, the process proceeds to step S201, and it is determined whether target information exists in the cache. Specifically, this step can be implemented by referring to step S101 shown in fig. 1, which is not described herein again.
Then, preferably, the process proceeds to step S202, and determines whether the target information in the cache needs to be updated. Further, those skilled in the art understand that in many cases, step S202 needs to be performed, for example, in order to improve the accuracy of target information management, target information in the cache needs to be updated at a fixed time, so as to avoid that a piece of information is already updated at the server, but information before update is still used in the client, because the information comes from the cache of the client. For another example, when an application program is just started, the corresponding cache cannot have the target information corresponding to the application program, so in the control method provided by the present invention, the corresponding target information also needs to be stored in the cache, which is also a way to update the target information in the cache. For another example, in another variation, the target information needs to be updated according to time intervals, for example, at 2.14 days, the weather information in the cache should correspond to weather information between 2.7 and 2.21 days, that is, the first 7 days of weather information and the last 7 days of weather information at the current time point. Then, when the day 2.16 is reached, the weather information of day 2.7 and day 2.8 needs to be deleted, and the weather information of day 2.22 and day 2.23 needs to be added, or new weather information needs to be directly added, etc. Those skilled in the art understand that the update of the target information does not necessarily need to update all the target information, and may also update only part of the target information, and these variations are within the protection scope of the present invention and will not be described herein.
The determination result in the above step S202 is negative, that is, if the target information does not need to be updated, the target information in the cache is used. In such a case, such target information is directly used if it is determined that the target information in the cache can meet the usage requirements of the current app.
The determination result in the above step S202 is negative, that is, if the target information needs to be updated, the target information in the cache is updated. Further, those skilled in the art will appreciate that all of the target information in the cache may be updated, or a portion of the target information may be updated, depending on the content of the information. Further, it will be appreciated by those skilled in the art that in another preferred embodiment, the update operation is preferably to obtain information from a data source and copy it to a cache, such as to copy the necessary information from a database, or to obtain the necessary information from a text file, or to copy the necessary information from a chat log. In another embodiment, the target information may also be a file in various formats, such as a video, which is very common when the advertisement information is a part of the target information, such as a picture, and these variations are within the protection scope of the present invention and will not be described herein.
After the step S203 is executed, the corresponding app uses the target information. Preferably, the target information is information copied from a database directly or information obtained from a server side, and is not required to be obtained from a cache. Further, those skilled in the art understand that when the step S204 is executed, the target information also exists in the cache because it has been updated to the cache.
Referring to the embodiment shown in fig. 2, it is understood by those skilled in the art that the step S202 can be implemented in various ways: and judging whether the target information in the cache needs to be updated or not. For example, in a preferred embodiment, the step S202 includes the following steps: b11. and judging whether the time to be updated of the target information in the cache is reached, and correspondingly, if the time to be updated is reached, determining that the target information needs to be updated. Still further, in such preferred embodiments, the step b11 may be implemented in various ways:
-determining whether an update time of the target information in the cache is greater than or equal to a minimum update time, wherein the minimum update time is a time period for updating the target information-a time period for displaying the target information in advance. In such a variation, the time at which the target information is to be presented is set in advance, and then the target information is updated once in the time before it is presented, so that the target information is the latest version before the presentation, that is, the latest version at present. Therefore, the information to be displayed can be ensured to be the current latest version information by setting the minimum updating time.
For another example, in another variation, the step b11 can be implemented as follows: and judging whether the time difference between the timestamp of the target information in the cache and the current timestamp is greater than a first threshold value. In such a variation, the cache is updated every 10 minutes, or every 24 hours, and the next update is initiated as long as the timestamp of the two timestamps is greater than or equal to the threshold.
For another example, in another variation, the step b11 can be implemented as follows: checking whether an interrupt or a reminder or a process for updating the target information is triggered. In such a variation, after the cache is updated each time, an interrupt or a process is set, and after each clock change, whether the interrupt comes or not is judged, so that the cache can be updated again.
For another example, in another variation, the step b11 can be implemented as follows: and judging whether the countdown for updating the target information expires. In such a variation, a countdown is set after each cache update, and the control device starts the step b11 when the countdown expires, which is not described herein again.
Still further, in another embodiment, the step S202 is implemented by the following steps: b11', judging whether the data source corresponding to the target information is updated, and accordingly, if the data source is updated, determining that the target information needs to be updated. In such variations, before using the target information, query information is first sent to the data source to determine whether the world updated last time is after the target information is updated, and if so, it indicates that the data source is not updated, and it is not necessary to update the target information in the cache.
Referring to the above embodiments shown in fig. 1 and fig. 2, it is understood by those skilled in the art that the target information is preferably a set of information, i.e. a set of multiple types of information, a set of multiple pieces of information, such as advertisement information, news information, weather information, etc., and these variations are within the scope of the present invention and will not be described herein again.
With reference to the embodiment and the variation shown in fig. 1 and fig. 2, it is understood by those skilled in the art that according to another aspect of the present invention, there is also provided a control apparatus for processing dynamic time period information cache, which includes the following apparatus:
the first judgment device is used for judging whether target information exists in the cache or not; and
and the first processing device is used for using the target information in the cache when the target information exists.
Referring to the embodiment and the variation shown in fig. 1 and fig. 2, it is understood by those skilled in the art that the first processing device preferably includes the following devices:
second judging means for judging whether the target information in the cache needs to be updated; and
and the second processing device is used for using the target information in the cache when the target information does not need to be updated.
Referring to the embodiment and the variation shown in fig. 1 and fig. 2, it is understood by those skilled in the art that the target information preferably includes any one of the following information:
-advertising information;
-weather information; or
-news information.
Referring to the embodiment and the variation shown in fig. 1 and fig. 2, those skilled in the art understand that the above steps and the corresponding variation may be combined to implement the above devices, and are not described herein again.
Through the self-variation of the various embodiments provided by the invention, at least the functions can be realized: configuration information in a certain time period is provided, the time interval is dynamically changed according to the current time, repeated calculation is avoided, cache is maximally utilized, and the actual effect of data updating is not influenced. More specifically, the general idea of the invention can be abstracted as follows:
1. acquiring data in a designated range from a database, storing the data in a cache, and recording a timestamp in the cache for judging the updating time of the cache data;
2. calculating the time for updating the data according to the dynamic time for acquiring the data, wherein the minimum updating time is the time period for acquiring the data-the time period for displaying the data in advance;
3. when data is acquired, according to the cache content, there are three situations:
1) when the cache does not exist, acquiring data from the database according to the current time, and acquiring a current timestamp and storing the timestamp into the cache;
2) if the cache exists, if the updating time of the cache is more than or equal to the minimum updating time, acquiring data from the database again, updating the version number, adding 0.01 to the version number of the original cache, acquiring the current timestamp again, and finally updating the current timestamp to the cache together;
3) and a cache is present, the updating time of the cache is less than the minimum updating time, and the cache data is directly used.
4. And when the background updates the configuration information, directly deleting the cache information.
The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes and modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
