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. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The application provides a cache information processing method, which comprises the steps of receiving an update request of cache information, determining a processing mode of the cache information according to the update request, and updating the cache information according to the determined update mode. The application also provides a device corresponding to the cache information updating method. By the method, the cache information can be processed in time, the pressure of returning to the source is reduced as much as possible, and the cache service can be stably and normally performed.
The following describes the method for updating cache information provided by the present application in detail with reference to the accompanying drawings.
In an embodiment of the present application, there is provided a cache information updating method, which may be applied to a cache server, as shown in fig. 1, and illustrates an updating method of cache information according to an exemplary embodiment, including:
the cache server receives an update request from an update request sender, e.g., from a source station.
And 102, determining an updating mode of the cache information according to the received updating request, and updating the cache information according to the determined updating mode.
The cache information may be information in any required form, and may also be stored in a required manner, for example, the cache information may be metadata of the relevant resource, and the metadata is stored on a disk.
The updating request comprises preset updating modes which are different, and the processing modes are different. Determining an update mode of the cache information according to the received update request comprises:
(A) judging whether a preset updating mode in the updating request is a batch updating mode, if so, determining batch cache information to be updated, recording the batch cache information in a regular expression mode, and simultaneously recording the updating type and the updating request time in the batch updating mode. And if the preset mode in the updating request is a batch updating mode, recording batch cache information required to be updated in a regular expression mode.
And determining cache information which is not updated according to the update type in the batch cache information in preset time, updating according to the update type, and recording the update time.
The update type of the batch cache information in the preset update mode may include:
a. forced expiration is carried out on batch cache information under the specified directory;
b. and deleting the batch cache information under the specified directory.
In order to reduce the processing pressure of the cache server, the update request of the batch cache information is not to update the batch cache information when receiving the update request of the batch cache information processing, but to update the batch cache information at a preset time. For example, the batch cache information may be updated when the load is low in the morning. In a predetermined time, when updating the batch cache information, it is determined which of the batch cache information has been updated according to the update type and which batch cache information has not been updated according to the update type. And updating the cache information which is not updated according to the updating type.
For the updating processing of the batch cache information, if the same batch cache information is submitted with a plurality of updating tasks before the preset time, the cache server takes the last updating request as the final updating task and records the time for receiving the updating request. For example, the source station sends a task of deleting the png batch cache files in the designated directory to the cache server, and sends a task of forcibly expiring png batch cache information in the designated directory to the cache server before a predetermined time, that is, the same batch cache information is forcibly expired, and the cache server records that the processing task of the batch cache information is forcibly expired, and records the update request time received by the task of forcibly expiring.
(B) Judging whether the preset updating mode in the updating request is a preset batch updating mode which is cancelled or not, if so, cancelling the preset batch updating mode according to the cancelling type
The preset revocation type in the updating mode may include:
e. canceling the operation of forcibly overdue the batch cache information under the specified directory;
f. and canceling the operation of deleting the batch cache information under the specified directory.
For revocation of update processing, when an update request is received, the update request is processed. For example, when a revocation request for forcibly expiring batch cache information in a specified directory is received, an operation for forcibly expiring preset batch cache information in the specified directory is revoked.
(C) And judging whether the preset updating mode in the updating request is the URL updating mode, if so, updating the URL cache information according to the updating type, and recording the updating time.
The preset update type of the URL cache information in the update mode may include:
c. forced expiration is carried out on URL cache information under the specified directory;
d. deleting URL cache information under the specified directory;
for the update of the URL cache information, when an update request is received, the update request is processed. For example, when an update request for deleting the URL cache information in the designated directory is received, the cache information is deleted.
The method for updating cache information provided by the application may further include: and storing the cache information in a cache server in a multi-level index mode. For example, a domain name may be used as a parent directory, and the corresponding cache information under the domain name is correspondingly stored under the index child directory. As shown in fig. 2. Fig. 2 illustrates an example of a storage manner using domain names as indexes. The domain name a has 5 pieces of cache information a1, a2, a3, a4 and a5, which are correspondingly stored in the directory of the domain name a. The pair of domain names B is correspondingly stored under the directory where the domain name B is located by 3 pieces of cache information B1, B2 and B3. The pair of domain names C has 4 cache information C1, C2, C3 and C4, which are correspondingly stored in the directory of the domain name C.
In executing step 102, the cache information may be determined by way of a multi-level index. For example, the cache information C1 needs to be updated in the update request, it may be determined that the cache information C1 is stored in the domain name C directory, and during the query, the domain name C directory may be directly locked, and then the cache information C1 is searched under the domain name C directory.
And caching the cache information in a multi-level index mode so as to facilitate searching, processing and pushing during processing and pushing. And all cache information does not need to be searched and processed in a traversal mode like in the traditional mode.
The information caching method provided by the application can further include: the same cached information in different text formats is identified. The identification mode may be set as required, for example, the same cache information in different text formats is identified in a character string and the first bit is the same, for example, a compressed version of a certain cache information is identified by 1a, and an uncompressed version of the cache information is identified by 1 b.
Before processing the cache information according to the determined updating mode, the cache information needing to be processed in all text formats can be determined through identification. For example, if the compressed version of the cache information c1 to be processed is identified as 1a and the uncompressed version is identified as 1b, then it can be determined that the cache information c1 to be updated includes two text formats, a compressed version and an uncompressed version. When the cache information is processed according to the determined processing method, the cache information c1 of the cache information c1 in two text formats is processed.
The storage states of different version formats of the same cache information are identified by marking the same cache information in different text formats, for example, a compressed version and an uncompressed version are identified, so that the same cache information in all different text formats can be processed at the same time during processing and pushing.
The application also provides a cache information pushing method, as shown in fig. 3. Fig. 3 illustrates a cache information pushing method according to an exemplary embodiment, which may be applied to a cache server, and includes:
The client sends an access request of the cache information to the cache server, and after the cache server receives the access request of the cache information, the cache server determines a processing mode of the cache information according to a preset processing mode and the latest processing time of the cache information.
If the update type in the preset processing mode is overdue, for example, the batch cache information is overdue or the URL cache information is overdue, judging whether the update request time of the preset processing mode is later than the latest processing time, if so, executing the preset processing mode, namely, overdue the corresponding cache information, and sending an inquiry request to a target server providing the cache information, for example, a source station; if the feedback information indicates that the cache information is the latest version, recording the receiving time of the feedback information as the updating time, and pushing the cache information to a processing request sending terminal; and if the feedback information carries the cache information of the updated version, covering the cache information of the updated version with the cache information and storing the cache information to a cache server, recording the updating time, and pushing the cache information of the updated version to a processing request sending terminal.
If the source station sends an overdue task for the png batch cache files including the 1.png files in the specified directory to the cache server before the client sends an access request for the 1.png files in the specified directory to the cache server. When the cache server receives an access request of a client, firstly judging that the preset processing mode of the cache information of the 1.png file is an overdue task of batch cache files, performing overdue processing on the cache information of the 1.png file, sending an acquisition request to a source station, if the feedback information of the source station is received, indicating that the cache information of the 1.png file is the latest version, for example, receiving a 304 state code returned by the source station, indicating that the cache information of the 1.png file is the latest version, recording the receiving time of the feedback information as the updating time by the cache server, and pushing the cache information of the 1.png file to the client. And if the feedback information received from the source station is 200 state codes and carries the cache information of the updated version, covering the cache information of the 1.png file on the cache server with the cache information of the updated version, storing the cache information of the updated version to the cache server, and recording the updating time. And pushing the cache information of the updated version to a sending end of the processing request.
If the update type in the preset processing mode is deletion, for example, deletion of batch cache information or deletion of URL cache information, judging whether the update request time of the preset processing mode is later than the latest processing time, if so, executing the preset processing mode, and sending an acquisition request to a target server providing the cache information; and updating corresponding cache information according to the feedback information, and pushing the updated cache information to a processing request sending terminal.
For example, if the source station sends a delete task to the cache server for a png batch of cache files that include 1.png files under a specified directory before the client sends an access request to the cache server for the 1.png files under the specified directory. When the cache server receives an access request of a client, firstly judging that the preset processing mode of the 1.png files is a task of deleting the batch cache files, deleting the 1.png files, sending an acquisition request to a source station, after receiving feedback information of the source station, storing the cache information of the 1.png files carried in the feedback information by the cache server, and pushing the updated cache information to the client.
The technical solution provided in the present application is described in detail below with reference to a specific example:
com, there are three files 1.png, 2.png, 3.png in total under the specified directory a.com of the cache server. The last treatment time was 8 months, 9 days, 10:00 in 2019.
Source station 8 month 10 day 13 in 2019: 00 sends a bulk expired request to the caching service specifying all of the png files under directory a.com. After receiving the batch expiration setting request, the cache server records cache information of all files with the end of png in the specified directory a.com in a regular expression mode, for example, the cache information is specified in an x-png mode, and records the processing mode of the batch cache information as expiration setting and the receiving time TG of the updating request as 13:00 of 8 months and 10 days in 2019. The given time may be any time set by the cache server, for example, the time may be selected to be performed when the load is low in the morning.
The source station is again in 2019, 8, 10, 15:00, sending a request for batch deletion of the batch cache information to the cache server again, namely deleting all the cache information of the files ending in the png under the a.com. The processing mode of the cache server for recording the batch cache information is deletion, and the receiving time TG of the updating request is recorded as 8 months, 10 days and 15:00 in 2019. In this case, the batch update method for the designated directory is batch deletion.
Client 16 in 2019, 8 month, 10 day: 00, sending an access request of a.com/1.png to a cache server, after receiving the access request, determining that a preset processing mode aiming at the cache information exists in the preset processing modes for deleting the batch of cache information, judging whether the update request time of the preset processing mode is later than the latest processing time of the cache information, finding that the update request time of the preset processing mode is 2019, 8, 9, 15:00 is later than the latest processing time of the cache information, 2019, 8, 9, 10:00, deleting the resource, namely a.com/1.png, sending a request for reacquiring the resource to a target server, such as a source station, caching the cache information of the resource returned by the target server, and recording the latest processing time of the cache data as 2019, 8, 10, 16: 00. and meanwhile, pushing the updated cache information to the client.
After the above processing, the latest processing time of the a.com/1.png in the cache server is 16:00 in 8/10/2019, and the latest processing time of the a.com/2.png and the a.com/3.png is 13:00 in 8/10/2019.
At a given time, 8 months and 11 days in the morning of 2019, 0:00, the cache server performs predetermined processing operations on a.com/1.png, a.com/2.png and a.com/3. png. Firstly, judging whether the set time of the preset processing mode is later than the latest processing time of the three files, wherein the latest processing time of a.com/1.png is 16:00 in 8/10/2019, and 15:00 in 8/10/2019, and the processing is not carried out. The latest processing time of the a.com/2.png and the a.com/3.png is 13:00 in 8 months and 10 days in 2019, the setting time of the preset processing mode is 15:00 later than the setting time of the a.com/2.png and the a.com/3.png in 8 months and 10 days in 2019, and the cache server deletes the cache information of the a.com/2.png and the a.com/3. png.
Client end in 2019, 8, 11, 10:00, sending an access request of a.com/2.png to a cache server, the cache server determining that no cache information about a.com/2.png exists through query, sending an acquisition request to a target server of the file, such as a source station or a server storing the file, and providing the cache information of the file to the cache server by the target server according to the acquisition request. The cache server stores the file and records the storage time as 8 months, 11 days and 10 days in 2019: 00, i.e. the most recent treatment time was 10:00 at 8 months and 11 days in 2019.
