Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the prior art, for example: when a certain television is broadcasted hot, the time for updating the video is up to night, and a large number of users are crowded to watch the video. The request amount of the background interface is soaring, the cache data can inevitably expire in the process of watching a video by a user, once the cache data expires, resources can only be obtained from the server, and great pressure is brought to persistent storage resources, so that the performance of the whole system is influenced. The method comprises the following steps:
step S101, acquiring the access frequency of cache content corresponding to the hot video in the cache;
in the embodiment of the present invention, a hot video may refer to a video with a heat value exceeding a preset threshold, where the heat value is a key indicator for determining whether the video is a hot video.
Exemplary, the heat value is scored specifically: the heat value includes a viewing behavior index, an interaction behavior index, and a sharing behavior index, and the weight of the data is distinguished according to the time period. Taking the content popularity as an example, in the calculation, the website refers to the values of two time periods: one is near 24 hours of viewing, interacting, sharing data; one is viewing, interacting, sharing data for nearly 30 days, and weighting higher with multidimensional data for nearly 24 hours. The watching data is not simply accumulated in playing amount, but is obtained by integrating data such as the number of users on the basis of calculating the integral time length and the completion degree of watching the video by the users, and even the positive film watching data and the film flower watching data need to be weighted and calculated, so that the watching data can reflect the watching quality better. As for the interactive behavior and the sharing behavior, the comprehensive calculation of the interactive behaviors such as user comments, praise, forward, barrage and the like is carried out, and the objectivity and the anti-cheating capability of the judgment are increased through an algorithm.
Before the step, a heat value of the video can be calculated firstly, and if the heat value exceeds a preset threshold, the video can be determined as a hot video; and a certain video can be manually set as a hot video according to the actual situation.
In this step, a predetermined hotspot video may be acquired, and the access frequency of the cache content corresponding to the hotspot video may be acquired in the cache, where the cache content may refer to a key (key) of the hotspot video; it may also refer to the name of the hotspot video, such as: "journey to the West"; but also the video content of the hotspot video, etc.
In practical application, the numerical value of the access frequency can be maintained by a server corresponding to the task center, and each time a certain video in the cache of the server corresponding to the service system receives access, a notification can be sent to the server corresponding to the task center, so that the server corresponding to the task center counts the access frequency of the cache content corresponding to the video.
In practical applications, in order to continuously extend the expiration time of the cached content, the step S101 may be executed again at intervals of a preset time period, where the preset time period may be set to 1 minute or 5 minutes, and so on according to actual requirements.
Step S102, determining a frequency interval where the access frequency is located and a frequency expiration time period corresponding to the frequency interval in a preset frequency time period corresponding relation;
in the embodiment of the invention, because the number of times of requests of the hotspot videos with different access frequencies to the interface cache is different, the access frequency can be used as a basis for determining the target expiration time.
In the embodiment of the present invention, different frequency intervals may be divided in advance according to the access frequency of the cache content, where the different frequency intervals correspond to different frequency expiration time periods, for example, as shown in table 1 below:
TABLE 1
| Frequency interval | Frequency overdue time period (unit: s) |
| Over 1000 | 1200 |
| 500-1000 | 600 |
| Within 500 | 300 |
In this step, the time interval in which the access frequency is located may be searched in table 1, for example, if the access frequency of a certain tv show is 1200 times in the hot-air time period, the time interval in which the 1200 times are located is 500-.
Step S103, calculating the target expiration time of the cache content based on a fixed basic expiration time period and the frequency expiration time period set during caching of the update data;
step S104, adjusting the original expiration time of the cache content to the target expiration time.
In the embodiment of the present invention, the target expiration time should be greater than the original expiration time, and since the expiration time of the cache content is adjusted from the shorter original expiration time to the larger target expiration time, the expiration time of the cache content is extended, so that the cache content corresponding to the hotspot video can be obtained from the cache in a longer time period (longer than the original expiration time) before the target expiration time, thereby reducing access to the persistent storage resource at the server end, and avoiding a sudden increase in access to the persistent storage resource at the server end due to expiration of the cache content in a shorter time.
In this step, the server corresponding to the task center may update the cache expiration time, that is, adjust the default expiration time of the cache content to the target expiration time.
According to the embodiment of the invention, the access frequency of the cache content corresponding to the hot spot video in the cache is obtained, the frequency interval where the access frequency is located and the frequency expiration time period corresponding to the frequency interval are determined in the preset frequency time period corresponding relation, the target expiration time of the cache content is calculated based on the fixed basic expiration time period and the frequency expiration time period which are set during cache updating data, and the original expiration time of the cache content can be adjusted to the target expiration time.
According to the embodiment of the invention, the target expiration time of the cache content can be automatically calculated according to the access frequency, and then the original expiration time of the cache content is adjusted to the target expiration time, so that the cache expiration time can be dynamically adjusted according to the access frequency of the hotspot video, the cache function is fully exerted, the pressure of persistent storage is reduced, the system stability is improved, and the condition that the cache content is expired in the hot broadcasting time period of the hotspot video due to the fact that the static default expiration time is kept unchanged all the time is avoided, and great pressure is brought to persistent storage resources, thereby affecting the performance of the whole system.
In a further embodiment of the present invention, before step S103, the method further comprises:
acquiring a hot playing time period of the hot video;
in the embodiment of the present invention, the hot-playing time period of the hot video may be calculated with reference to the video update time, for example: the update time period of "journey to the west" is 20: 00, each set is 1 hour long, the playing time period 20 of the video can be set as follows: 00-21: 00 is determined as a hot-cast period.
Because the access quantity of the hotspot video in the hot broadcast time period is greatly different from that of the hotspot video in the non-hot broadcast time period, the number of times of the hotspot video requesting the interface cache in the hot broadcast time period is greatly increased, and the number of times of the hotspot video requesting the interface cache in the non-hot broadcast time period is possibly in a normal range, the sum of the hot broadcast time periods can be used as a basis for determining the target expiration time.
Judging whether the current moment is within the hot broadcast time period;
in practical applications, it may be determined whether the current time is within the hot-air time period every 0.5 second, 5 seconds, 10 seconds, or 1 minute, and the like, and the interval may be slightly longer in order to save resources, but should be smaller than the interval between the target expiration time and the default expiration time.
In this step, the current time may be compared with the smaller boundary and the larger boundary of the hot-cast time period, respectively, and if the current time is greater than the smaller boundary and less than the larger boundary, it may be determined that the current time is within the hot-cast time period, and if the current time is less than the smaller boundary or greater than the larger boundary, it may be determined that the current time is outside the hot-cast time period.
If the current moment is within the hot broadcast time period, acquiring an additional time period corresponding to the hot broadcast time period;
in the embodiment of the present invention, an additional time period may be preset, for example: an additional period of 300s (seconds), and so on.
Based on the foregoing, the step S103 includes:
and determining the sum of the additional time period, the frequency expiration time period and a fixed basic expiration time period set during the caching of the updated data as the target expiration time of the cached content.
In the embodiment of the present invention, a fixed basic expiration time period set when the updated data is cached may be preset, for example: the base expiration period is 300s (seconds), etc.
In this step, 300+300+1200 may be determined as the target expiration time, that is, the cache content may expire at 1800s (seconds) from the current time.
According to the embodiment of the invention, when the current time is within the hot broadcast time period, the target expiration time can be calculated according to the sum of the basic expiration time period, the additional time period and the frequency expiration time period, the variable of the relation between the current time and the hot broadcast time period is introduced, and when the current time is within the hot broadcast time period, the influence of the calculation process is considered, and the hot broadcast expiration additional time period is added after the sum of the basic expiration time period and the frequency expiration time period is calculated, so that the target expiration time obtained by final calculation is more accurate and appropriate.
Based on the foregoing embodiment, in another embodiment of the present invention, step S103 may further include the following steps:
if the current time is outside the hot broadcast time period, determining the sum of the basic expiration time period and the frequency expiration time period as the target expiration time;
in this step, it may be determined that 300+1200 is 1500s (seconds) as the target expiration time, that is, the cache content expires at 1500s (seconds) from the current time.
According to the embodiment of the invention, when the current time is outside the hot broadcast time period, the target expiration time can be calculated according to the basic expiration time period and the sum of the frequency expiration time periods, the influence of the calculation process is not considered when the current time is outside the hot broadcast time period by introducing the variable of the relation between the current time and the hot broadcast time period, and after the sum of the basic expiration time period and the frequency expiration time period is calculated, an additional time period is not added, so that the target expiration time obtained by final calculation is more accurate and appropriate.
Since the foregoing embodiment adjusts the original expiration time to the target expiration time, the expiration time of the cache contents has been extended, but in practical applications, there may be some special cache contents, such as: in another embodiment of the present invention, the method further includes that the method includes:
and before the target expiration time of the hotspot video is reached, if an advance updating notice is received, updating the cache content corresponding to the hotspot video in the cache.
In the embodiment of the present invention, the advance update notification may include the update content, or the update content may be sent to the server corresponding to the task center in another manner, and the server corresponding to the task center may update the cache content according to the update content when receiving the advance update notification, that is: and updating the original cache content in the cache into the updated content.
