It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.
The following describes a cache object updating method, apparatus, device and storage medium according to an embodiment of the present application with reference to the drawings.
The embodiment of the application provides a cache object updating method, wherein before the expiration date of a cache object in a cache server is finished, whether the cache object needs to be updated in advance is judged according to relevant state information corresponding to the cache object, and when the cache object needs to be updated in advance, the cache object can be updated in time, so that the response delay of a client caused by updating the object after the expiration date is finished is avoided. In addition, the embodiment of the application provides a more intelligent way for judging whether to update the object by improving the update condition of the object, can adapt to more and more complex network service environments, integrates one or more combinations of the system state of the cache server, the state of the client requesting the object and the state of the object, and determines the adopted object update strategy by integrating the aspects. The method is beneficial to improving the condition that the cache server provides a more accurate cache object for the client under the conditions of different geographic positions, load levels, network environments, source server states and the like, and the cache object is updated more timely.
In an embodiment of the present application, the object may be a character string, a file, or other data, and the cache server may be a cache server in a CDN (Content Delivery Network), or may be a database or a server having a cache function.
Referring to fig. 1, the method specifically includes the following steps:
step 101: receiving an object acquisition request sent by a client, and determining that a cache object corresponding to the object acquisition request exists and the validity period does not reach.
An execution main body of the embodiment of the application is a cache server, a network architecture where the cache server is located is shown in fig. 2, the network architecture comprises the cache server, a source server and a client, the client is connected with the cache server through a network, and the cache server is connected with the source server through the network. The source server may be another cache server located at a higher level than the cache server, or may be a source station as an object provider, such as a server of a website owner in an HTTP website. In the network architecture, a cache server acquires an object from an origin server and caches the object, and a client acquires the object from the cache server.
When a user needs to check a certain object, an object acquisition request is sent to the cache server through the client, and the object acquisition request carries client identification information, object identification information corresponding to the requested object and the like. The client identification information may be a device identification or an IP (Internet Protocol) address corresponding to the client. The object identification information may be a URL (Uniform Resource Locator) of the object, and the object identification information may also include protocol information, for example, HTTP:// test.com/path/a.mp4 may be object identification information corresponding to an a object in mp4 format, and the protocol information is an HTTP protocol.
A large number of cache objects are stored in the cache server, and each cache object is stored corresponding to respective object identification information. And each cache object is provided with a corresponding validity period, and the cache object can be used for providing service for the client only if the cache object is valid in the validity period of the cache object. And after the validity period is exceeded, the cache object is invalid and can not be used for providing service for the client. After receiving the object obtaining request sent by the client, the cache server parses the object identification information from the object obtaining request, queries whether a cache object corresponding to the object identification information exists in a local cache, if so, judges whether the current system time reaches the validity period corresponding to the cache object, and if not, judges whether the cache object needs to be updated in advance through step 102 and subsequent operations.
If the cache server does not inquire the cache object corresponding to the object identification information in the local cache, or the cache object corresponding to the object identification information is inquired, the validity period corresponding to the cache object is judged to be reached, the fact that an object capable of responding to the object acquisition request of the client does not exist in the current cache server is indicated, the cache server directly sends an object updating request to the source server, and the object updating request carries the object identification information. After receiving the object update request, the source server obtains the latest version object with the highest version in all the objects corresponding to the object identification information, and sends the latest version object to the cache server. The cache server receives the latest version object and sends the latest version object to the client. The cache server also locally caches the corresponding relation between the object identification information and the latest version object, and records the updating time of the latest version object and the setting period of validity for the latest version object. If the cache server stores the overdue cache object corresponding to the object identification information, the corresponding relation between the object identification information and the overdue cache object and the information such as the validity period corresponding to the overdue cache object are deleted.
Step 102: and acquiring the relevant state information corresponding to the cache object.
If the cache server determines that the cache object corresponding to the object obtaining request of the client is locally stored in step 101 and determines that the validity period of the cache object does not reach, obtaining relevant state information corresponding to the cache object, where the relevant state information includes one or more combinations of object state information corresponding to the cache object, client state information corresponding to the client, and system state information corresponding to the cache server.
The object state information corresponding to the cache object includes one or more combinations of state information such as the last update time, the valid state, the valid period, the object type, the object caching requirement indicated by the source server, the concurrence condition, the state responded by the last update source server, the attribute change condition of the last update, the requested times and the like. The client state information includes client identification information, protocol information, request parameters, and the like. The system state information corresponding to the cache server includes the geographical location where the cache server is located, the system time, the time zone where the cache server is located, the network environment or the current system state of the cache server, and the current system state includes the load level of the cache server, the length of the waiting queue or the state of other related software.
Step 103: and judging whether to update the cache object in advance according to the relevant state information, and if so, executing the step 104.
In this embodiment, a preset configuration rule is set in the cache server, and the preset configuration rule specifies that different state information correspondingly adopts different update-ahead rules, for example, the preset configuration rule may specify that an object with an object type of mp4 is updated 5 minutes ahead, and so on.
After the relevant state information corresponding to the cache object is obtained through step 102, the update condition corresponding to the cache object is determined according to the preset configuration rule and the obtained relevant state information. Specifically, according to the acquired relevant state information, an advance update rule which the cache object conforms to is determined from preset configuration rules, wherein the advance update rule at least comprises an advance time length for updating the cache object in advance. And generating an updating condition corresponding to the cache object according to the determined advance updating rule and the validity period of the cache object.
In an embodiment of the present application, the update condition may be that, if the time when the object acquisition request corresponding to the current cache object is received is located within a range of a time length ahead of the validity period of the cache object, the cache object is updated.
In some embodiments of the present application, since there are objects of object types with larger data volume, the objects are usually provided with longer validity period, and the objects with larger data volume can be updated in advance for a longer time. For an object with a small data volume and a short validity period, a short advance time length can be set, and even advance updating is not performed. The preset configuration rules specify the corresponding relationship between some object types and the advance time length. After the cache server obtains the relevant state information corresponding to the cache object, the object type of the cache object is extracted from the relevant state information, and the advance time corresponding to the object type is determined from the preset configuration rule.
Under the condition that the advance time length is longer, in order to avoid the change of the cache object in the last advance time length, a periodical updating rule is set in the preset configuration rule when the advance time length is greater than a preset threshold value, and the periodical updating rule is used for stipulating updating once every preset unit time length. Therefore, after the advance time length corresponding to the object type is determined through the above method, if the advance time length is greater than the preset threshold, the periodic update rule is obtained from the preset configuration rule, and the advance time length and the periodic update rule are determined as the advance update rule which the cache object conforms to. The preset unit time may be 1 minute or 1.5 minutes, etc. The preset threshold may be 2 minutes, 3 minutes, or 5 minutes, etc.
After the updating rule in advance corresponding to the cache object is determined through the method, the updating condition corresponding to the cache object is generated according to the determined updating rule in advance and the validity period of the cache object. Namely, the updating-ahead time is determined according to the validity period of the cache object and the updating-ahead time length included in the updating-ahead rule. And determining each updating time of the periodic updating according to the advanced updating time, the validity period and the periodic updating rule. And determining the determined advanced updating time and each updating time of the periodic updating as the updating condition corresponding to the cache object. Subsequently, whether the cache object needs to be updated in advance can be judged by judging whether the current time belongs to the updating time included in the updating condition.
As to the above-described manner of determining the update condition according to the object type, the validity period, and the like of the cache object, a specific example is described below. For example, mp4 type objects are typically used for video on demand, and objects are larger with longer validity periods. The corresponding advance time length of the object type MP4 is configured to be 5 minutes in the preset configuration rule, and the advance time length is set to be more than or equal to 5 minutes and is updated every other minute. When the object identification information carried in the object acquisition request sent by the client is http:// test.com/path/a.mp4, after the cache object a is judged to be stored in the cache server and the validity period of the cache object a is not reached, the relevant state information corresponding to the cache object a is acquired, and the relevant state information comprises the object type mp4, the validity period 11:00 and the like of the cache object a. According to the requested object type mp4, the advance time length corresponding to mp4 is obtained from the preset configuration rule for 5 minutes and is determined to be updated every other minute within 5 minutes. According to the periodic updating rule that the time length is 5 minutes in advance, the updating is carried out every other minute and the effective period is 11:00, the updating time corresponding to the cache object a is determined to comprise 10:55, 10:56, 10:57, 10:58, 10:59 and 11: 00. If the time when the current object request is received is within the range of the advanced time length before the validity period of the cache object (for example, 10:56:10), determining that the update condition corresponding to the cache object a is that the cache object a is actively or based on the client request to be updated at the current system time (10:56:10) and/or when the system time reaches the update times (10:57, 10:58, 10:59, and 11: 00). And subsequently carrying out updating operation when the system time is judged to reach 10:57, 10:58, 10:59 or 11: 00.
Optionally, when the cache object a corresponds to multiple update times, if there are multiple requests in each period of the update time, only one time of source return update is needed.
Unlike mp4 files, m3u8 files are often used for live broadcasting, are small and have short validity time, so that no update rule is set for m3u8 files in preset configuration rules, and update is performed when the files fail. Or setting the advance time length corresponding to the file type m3u8 as 0 in the preset configuration rule, and not updating the file before the validity period of the m3u8 is ended. When the file identification information carried in the file acquisition request sent by the client is http:// test.com/path/b.m3u8, after the cache object b is judged to be stored in the cache server and the validity period of the cache object b is not reached, the relevant state information corresponding to the cache object b is acquired, and the relevant state information comprises the file type m3u8, the validity period 11:00 and the like of the cache object b. According to the requested file type m3u8, querying the corresponding advance time length from the preset configuration rule to know that the advance time length corresponding to m3u8 is 0 or the advance time length corresponding to m3u8 is not configured in the preset configuration rule, not setting an updating condition for the cache object b, and then actively updating the cache object b or based on a client request after the system time reaches 11:00 (including 11: 00).
In other embodiments of the present application, some cache objects in the cache server are requested a large number of times in a short time, in order to reduce the waiting time for the client to request the cache objects, a short advance time length is configured in the preset configuration rule for the cache objects, and in order to ensure that the objects are synchronized with the source server within the advance time length, the cache objects are set in the preset configuration rule to be updated again at the end of the valid period of the cache objects. Specifically, the cache server records a corresponding relationship between the object identification information of each cache object and the requested times, and the requested times of the cache objects only record the requested times within a preset duration closest to the current time. After the cache server obtains the relevant state information corresponding to the cache object, the requested times of the cache object in the preset time length closest to the current time are determined according to the object identification information of the cache object, which is included in the relevant state information. If the requested times are greater than the preset times, acquiring an advance time length corresponding to the preset times and an expiration updating rule from a preset configuration rule, wherein the expiration updating rule is used for stipulating updating when the valid period of the object is ended. And determining the advance time length and the expiration updating rule as the advance updating rule which is accorded by the cache object. The preset time period may be 10 seconds or 15 seconds. The preset number of times may be 100 times, 200 times, etc.
After the updating rule in advance corresponding to the cache object is determined through the method, the updating condition corresponding to the cache object is generated according to the determined updating rule in advance and the validity period of the cache object. Namely, the updating-ahead time is determined according to the validity period of the cache object and the updating-ahead time length included in the updating-ahead rule. And determining each updating time of the periodic updating according to the updating time in advance, the valid period and the due updating rule. And determining the determined advanced updating time and the determined due updating time as the updating condition corresponding to the cache object. Subsequently, whether the cache object needs to be updated can be judged by judging whether the current time belongs to the updating time included in the updating condition.
With regard to the above-described manner of determining the update condition according to the information of the requested number of times, the validity period, and the like of the cache object, a specific example will be described below. For example, the preset configuration rule sets an advanced time length corresponding to a cache object whose requested times exceed 100 times within 10 seconds to be 10 seconds, and sets an expired update rule that is updated again when the validity period of the cache object is over. When the object identification information carried in the object acquisition request sent by the client is http:// test.com/a/body.css, after the cache object body is judged to be stored in the cache server and the validity period of the cache object body is not reached, the relevant state information corresponding to the cache object body is acquired, wherein the relevant state information comprises the object identification information http:// test.com/a/body.css, the validity period 11:00 and the like of the cache object body. And determining that the number of requests in the cache object body in 10s is 120 according to the object identification information http:// test.com/a/body.cs, and acquiring the corresponding advanced time length of 10s and the due update rule from the preset configuration rule. According to the advanced time length 10s, the expired update rule and the valid period 11:00, if the time when the current object request is received is within the range of the advanced time length before the valid period of the cache object, for example, 10:59:50 (or 10:59:51), the update time of the cache object body is determined to include 10:59:50 (or 10:59:51) and 11: 00. and determining that the updating condition corresponding to the body of the cache object is that the system time reaches 10:59:50 (or 10:59:51) or 11: and updating the cache object a when 00. In the embodiment of the application, only the first one of the received object requests is updated in each update time interval.
In this embodiment of the application, for any one or more of the object state information, the client state information, and the system state information of the cache server included in the relevant state information, which is similar to the object type and the requested times, a corresponding advance update rule may be configured in a preset configuration rule. And the cache server matches the advance updating rules which are mostly met by the cache object from the preset configuration rules according to the relevant state information, so as to determine the updating conditions corresponding to the cache object.
As an example, the update condition of the cache object is determined for the system state information of the cache server included according to the relevant state information. For example, the system state information of the cache server includes a system load level, and the cache server may obtain a current load value of the system in real time through the monitoring system, and determine whether the load value within a certain time period closest to the current time is lower than a preset value, where the certain time period may be 10 minutes or 15 minutes, and the preset value may be 10 or 15, and the like. If the load value within a certain time length is judged to be lower than the preset value, the advanced updating is started, the updating and checking frequency is increased, and the updating time delay of the cache object is reduced. If the load value within a certain time length is configured to be lower than the advance time length corresponding to the preset value in the preset configuration rule, the cache object is updated at the time of the advance time length before the validity period of the cache object reaches. And shortening the updating and checking frequency, namely shortening the certain time length, for example, judging whether the load value within 15 minutes nearest to the current time is lower than a preset value before, and judging whether the load value within shorter time lengths such as 10 minutes or 8 minutes nearest to the current time is lower than the preset value after the updating and checking frequency is shortened.
For the streaming media cache objects with object types of mp4 and TS (Transport Stream), the scheme of determining the update condition according to the load value may not be adopted, and the scheme of determining the update condition according to the object type, the requested times, and the like and updating in advance is maintained, which is beneficial to smooth playing of real-time streaming media.
In other embodiments of the present application, the update condition may also be determined in combination with a load value of the system and a preset time period. For example, assuming that the preset time period is between 8:00 and 23:00, according to the load value, if the load value is lower than 10 in the last 15 minutes, the cache objects with the data volume larger than 10M are kept updated and checked 5 minutes earlier, and at least one check per minute is kept when requested, so that the update delay of the larger cache objects and the quality of the service at the moment of expiration are reduced. If the load value is lower than 30 in the last 15 minutes, the cache objects with the data volume larger than 100M are kept updated and checked 5 minutes earlier, and the last minute is checked once when the cache objects are requested, so that the updating delay of the larger cache objects and the quality of the service at the moment of expiration are reduced. If the load value is more than or equal to 30 in the last 15 minutes, only the cache objects of mp4, TS or other real-time streaming media formats are updated in advance, and only necessary cache objects are updated in advance as far as possible, so that the system pressure is reduced. And only updating and checking the cache object in the real-time streaming media format in advance between 23:00 and 8:00 of the second day, so that the system pressure is reduced, and more resources are reserved for other tasks.
In some embodiments of the present application, for the geographic location information included in the system state information of the cache server, the update condition of the cache object may be determined according to the geographic location information. Specifically, whether the location of the cache server is located in the remote area can be determined according to the geographical location information, for the cache server in the remote area, a full-scale advanced update check is started, and an advanced time length corresponding to the geographical location information of the remote area can be set in a preset configuration rule, that is, all cache objects stored by the cache server in the remote area are updated in advance of the advanced time length corresponding to the geographical location information of the cache objects. Therefore, the problem of delay in updating the cache object caused by poor network environment in remote areas can be solved, and the problem of poor service quality of the first request after the cache object is expired can be avoided.
In some embodiments of the present application, for the network environment state included in the system state information of the cache server, the update condition of the cache object may also be determined according to the network environment state. And particularly, when the network quality of the upstream node is better, the advanced updating is reduced, and the system load is reduced. When the network quality is poor, in order to optimize the user experience, a wider range of advanced updating is started, the advanced updating duration is prolonged, and the updating verification frequency is increased.
After the updating condition of the cache object requested by the client is determined through any one of the above manners, whether the current cache object meets the updating condition is judged. That is, it is determined whether the current system time reaches the update time included in the update condition. If so, it is determined that the cache object needs to be updated in advance, and then the operation of step 104 is performed. If not, determining that the cache object does not need to be updated in advance, and directly sending the currently stored cache object to the client.
Step 104: updating the cache object in advance, and responding to the object acquisition request.
If the updating condition of the cache object is determined to be currently met in step 103, acquiring a latest version object corresponding to the cache object from the source server, and replacing the locally stored cache object with the latest version object; and sending the latest version object to the client. That is, as shown in a of fig. 3, the cache server sends an object update request to the origin server, where the object update request includes the object identification information of the cache object. And receiving a latest version object corresponding to the object identification information returned by the source server, replacing the locally stored cache object with the latest version object, and sending the latest version object to the client. Therefore, the client can be ensured to obtain the latest version object, and the accuracy of object acquisition is improved.
In other embodiments of the present application, the cache object may be sent locally to the client. And meanwhile, acquiring the latest version object corresponding to the cache object from the source server through a local background, and replacing the locally stored cache object with the latest version object. That is, as shown in b of fig. 3, the cache server sends the cached object to the client, and simultaneously sends an object update request to the origin server in the background, where the object update request includes the object identification information of the cached object. And receiving the latest version object corresponding to the object identification information returned by the source server, and replacing the locally stored cache object with the latest version object. Therefore, the client can be responded as soon as possible, and the waiting time of the user is shortened.
In this embodiment of the present application, when the source server responds to an object update request of the cache server, if the latest version object exists, the source server may send the latest version object and a first status code to the cache server, where the first status code is used to indicate that the source server returns a complete latest version object. For example, the first status code may be the HTTP status code 200. The source server may further compare the latest version object with the cache object, obtain a part of object content of the latest version object, which is different from the cache object, and send the obtained part of object content and a second state code to the cache server, where the second state code is used to indicate that the source server returns the updated part of object content, and for example, the second state code may be the HTTP state code 206. After receiving the part of the object content, the cache server generates the latest version object according to the part of the object content and the cache object. If the latest version object does not exist in the source server, the source server may send a third status code to the cache server, where the third status code is used to indicate that the object in the source server is not updated. For example, the third status code may be the HTTP status code 304.
In some embodiments of the present application, when the cache server requests to update the cache object in advance, the cache object in the origin server may not be updated yet, in this case, if the object is also obtained from the origin server and updated, the waste of network resources is caused, and the processing pressure of the origin server is increased. In order to save network resources and reduce the pressure of the origin server, in the process of acquiring the latest version object of the cache object from the origin server, the embodiment of the present application may further generate an object update request corresponding to the cache object, and add the version identifier of the cache object in the object update request. The object update request is then sent to the origin server. And after receiving the object updating request, the source server compares whether the version identification is consistent with the version identification of the latest version object corresponding to the cache object stored in the source server, if so, the source server indicates that the object is not updated in the source server, and then sends an indication message that the object is not changed to the cache server. And after receiving the indication message, the cache server sends the locally stored cache object to the client. And if the source server compares that the two version identifications are inconsistent, the source server indicates that the object is updated in the source server, and the corresponding latest version object is sent to the cache server. The cache server receives a latest version object corresponding to the version identification returned by the source server, sends the latest version object to the client, and replaces the locally stored cache object with the latest version object.
The adding of the version identifier of the cache object in the object update request may specifically be adding the version identifier in a header of the object update request. For example, assuming that the object update request is an HTTP message, a version identifier may be added to an If-Modified-site field or an ETag field in a header of the HTTP message, or other object version information that can be recognized by the source server may be adopted. When the cached object has no known available version identification, the last update time of the cached object can be added in the object update request, so that the origin server determines the version of the cached object through the last update time.
In order to facilitate understanding of the object updating method provided in the present application, the following description is made with reference to the accompanying drawings. As shown in fig. 4, S1: and receiving an object acquisition request sent by a client. S2: and judging whether the cache object corresponding to the object acquisition request is stored, if so, executing the step S3, and if not, executing the step S7.
