A Content Delivery Network (CDN) node usually includes multiple cache devices, which are generally more than 10 devices according to different sizes, and one resource (e.g., video, picture, etc.) is often cached only on one or more cache devices in the node, but a client does not know which devices are cached specifically. Therefore, in the conventional CDN node refresh scheme, a refresh request for one resource is sent to all cache devices in a node to ensure that the refresh is successful. However, this refresh method may amplify a request invalidity, for example, if there are 10 devices in a CDN node and only one device caches a target resource, if a refresh request of the target resource is sent to all 10 devices in the node, it is equivalent to amplify the refresh request by 9 times, thereby increasing the operation difficulty of the client and the cache pressure of the CDN.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
For a common Internet user, each CDN node is equivalent to a website server placed around it, and through taking over DNS (Domain Name System), the user's request is transparently directed to the node closest to it, and the CDN server in the node responds to the user's request like the origin server of the website, and thus the response time is necessarily faster because it is closer to the user. The intelligent scheduling DNS is a key system in the CDN service, when a user accesses a website added with the CDN service, a domain name resolution request is finally processed by the intelligent scheduling DNS, and a node address closest to the user at that time is provided for the user through a set of predefined strategies, so that the user can obtain rapid service. Meanwhile, it needs to keep communication with CDN nodes distributed in various regions, track health status, capacity, and the like of each node, and ensure that a user's request is distributed to nodes available nearby.
As shown in fig. 1, it is a schematic view of a scenario for accessing a CDN network, where when a client accesses the CDN network, an interaction between the client and a domain name system DNS and an edge node in the CDN network is a necessary flow, and an interaction between the edge node, a middle node, an upper node, and a source station is an optional flow, where if a cache is hit in the edge node, the access does not involve an interaction between the edge node and another node (i.e., the flow does not pass through a dotted line portion in fig. 1).
Referring to fig. 2, a schematic diagram of an architecture of a content delivery network is shown, where the CDN node includes multiple Cache caches and multiple proxy servers Nginx, each Nginx is communicatively connected to a Linux Virtual Server (LVS), and in actual operation, an access request of a user is sent to each proxy Server Nginx through the LVS, and the Nginx provides a load balancing service, and distributes the access request to the Cache caches to respond to the access request.
In actual operation, when a user accesses the CDN network, the edge nodes directly serve the user (netizen), and the number is the largest; the middle-layer nodes are mainly source returning requests of the aggregation edge nodes, do not directly serve the netizens, and are fewer in number; the upper node mainly converges the request of the middle node to the source, and does not directly serve the netizens, and the number is relatively minimum. Also, typically the user does not need to pay for the bandwidth generated by the middle/upper nodes.
In consideration of the problems that the existing CDN node refresh method may cause many invalid refresh requests and increase the cache pressure of the CDN node, embodiments of the present invention provide a method and an apparatus for data refresh, and an electronic device. For the convenience of understanding the present embodiment, a detailed description will be given to a data refreshing method disclosed in the present embodiment.
Referring to fig. 3, which is a schematic flowchart of a method for refreshing data according to an embodiment of the present invention, wherein the method is applied to a node server, as shown in fig. 3, the method includes the following steps:
step S302: a refresh request for target data is received.
The target data may be a video, a picture, a document, or the like, and the refreshing of the target data may include at least one of adding data, deleting data, and modifying data. The node server may be an edge node server in the CDN network, and directly receives a refresh request of a user for target data, and forwards the refresh request to a cache device in the node, so that the cache device performs a refresh operation on the data according to the refresh request.
Step S304: determining whether the target data is stored in the local cache, if so, executing step S306; if not, step S308 is performed.
After receiving a refresh request, the node server firstly determines whether the target data is stored in a local cache, and if the target data is stored, the node server refreshes the target data according to the refresh request; if the target data is not stored, a refresh success is returned directly without forwarding the refresh request to a cache device within the node.
Generally, each CDN node contains multiple cache devices, but for a specific resource, such as a video, a picture, etc., only one or more cache devices are cached, and a client itself does not know which cache device the resource is cached in, so to ensure that a refresh is successful, a conventional refresh method is to hit a refresh request for the resource to all cache devices in the node, which may result in invalidating the refresh request by multiple times. In this embodiment, the node server determines in advance whether the target data to be refreshed is stored in the local cache, and if the target data to be refreshed does not exist in the local cache, it is not necessary to forward the refresh request to the cache device in the node, so that invalid refresh is avoided, and an effective refresh request is passed through to the cache device.
Step S306: and refreshing the target data according to the refreshing request.
And if the node server confirms that the target data is stored in the local cache, releasing the refreshing request, transmitting the refreshing request to the cache equipment, and performing data refreshing operation by the cache equipment according to the refreshing request.
Step S308: and returning the refreshing success.
If the node server confirms that the target data is not stored in the local cache, it indicates that the refresh request is an "invalid" request, i.e., even if the refresh request is sent to each cache device, no data update actually occurs, and thus, an unnecessary refresh operation is performed. In this embodiment, if the target data is not stored in the local cache, the refresh success is directly returned. Therefore, the method saves the operation of sending the refresh request to each cache device, and each cache device does not need to carry out 'invalid' refresh according to the refresh request.
According to the data refreshing method provided by the embodiment of the invention, when a refreshing request aiming at target data is received, whether the target data is stored in a local cache or not is firstly determined, if the target data is stored in the local cache, the target data is refreshed according to the refreshing request, and otherwise, the refreshing success is directly returned. In the method, the node server filters the refreshing request in advance, and only the refreshing information of the data in the local cache is transmitted to the cache device for refreshing, so that invalid refreshing requests are filtered, the cache pressure of the CDN node is reduced, and the refreshing efficiency and the refreshing success rate are improved.
On the basis of the method for refreshing data shown in fig. 1, the present embodiment has been described with respect to a specific implementation manner of step S304 (determining whether the local cache stores the target data) in the foregoing embodiment, so as to facilitate a deeper understanding of the scheme.
Fig. 4 is a schematic flow chart of another method for refreshing data, which is applied to a node server, and as can be seen from fig. 4, the method includes the following steps:
step S402: a refresh request for target data is received.
Step S404: and acquiring an index directory of the cache data in the local cache.
In one possible implementation manner, a refresh proxy service may be set on the node server, and when the node server monitors that the refresh proxy service is started, a communication connection between a cache service corresponding to a local cache and the refresh proxy service is established. In other possible embodiments, the refresh agent service may also be configured to start up.
The cache service is further configured to generate an index directory of the local cache data, so that the refresh agent service can obtain the index directory of the cache data from the cache service, and further determine whether the target data exists in the local cache according to the index directory. In practical operation, after the cache service establishes communication connection with the refresh proxy service, the index directory of the cached data in the local cache can be synchronized to the refresh proxy service in real time in a heartbeat manner, so that the refresh proxy service can know the latest cached data condition in the cache device.
Step S406: and searching the index of the target data from the index directory.
For example, the refresh agent service may perform lookup according to the obtained index directory, and determine whether there is an index of the target data in the index directory.
Step S408: determining whether the target data is stored in the local cache or not according to the index search result of the target data, and if so, executing the step S410; if not, step S412 is performed.
If the index of the target data is found in the index directory, the target data is stored in the local cache, so that the target data is refreshed according to the refreshing request, specifically, the refreshing request is released and sent to the cache device, so that the cache device refreshes the target data according to the refreshing request.
If the index of the target data is not found in the index directory, the target data is not stored in the local cache, at the moment, the refreshing request is intercepted, the refreshing request is not sent to the cache equipment, and the refreshing success is directly returned. In other possible embodiments, a prompt may be returned to the user indicating that the target data is not stored in the local cache.
Step S410: and refreshing the target data according to the refreshing request.
Step S412: and returning the refreshing success.
Here, the steps S410 and S412 correspond to the steps S306 to S308 in the above embodiment, and the corresponding contents may refer to the corresponding parts in the above embodiment, which are not described herein again.
In order to more clearly understand the data refreshing method provided by the present embodiment, an application example is introduced here. Referring to fig. 5, which is a schematic flow diagram of CDN node refresh provided in an embodiment of the present invention, in an implementation shown in fig. 5, a process of refreshing a CDN node by using a data refresh method in the foregoing embodiment is shown, where a refresh proxy service (refresh) is run on the CDN node, and the refresh process is as follows:
firstly, a client submits a refresh request to a refresh center through a console or an API (Application Programming Interface), and the refresh center distributes the refresh request to an agent on a relay machine of a CDN node.
When the refreshing proxy service is started, the caching device is actively connected, all directory information is requested to be obtained from the caching device, a local directory structure is established, and then the long connection is maintained with the caching service of the caching device in a heartbeat mode. Here, when the cache device is normally served, the newly added or deleted cache file is synchronized in real time to the refresh proxy service through the long connection, and the refresh proxy service maintains a content directory in the cache device, and the two are kept consistent.
Then, when the refresh request is sent to the refresh proxy service, the refresh proxy service filters the refresh request according to the directory information of the cache data, if the target resource requested to be refreshed exists in the local cache, the refresh request is required to be processed, and then the refresh request is transmitted to the cache device, and is returned to the client after the refresh is successful.
Therefore, in the CDN node, because the refreshing request of the customer is filtered through the refreshing proxy service, only the refreshing information of the data existing in the local cache is transmitted to the cache service program, so that the node refreshing pressure is reduced, and the refreshing efficiency is improved.
In practical applications, for example, during a large-scale e-commerce promotion activity, pictures of a product activity detail page need to be updated in real time, and it is estimated that a single machine needs to support processing of a refresh request of 20k QPS (query-per-second), and such high-frequency refresh requests may cause a great pressure on a cache device in a node, which affects normal netizen access. In addition, because the refreshing proxy service is arranged in the node server, and the requirement for filtering the refreshing request is stripped from the cache service to the refreshing proxy service, the basic storage function of the cache service can be further restored.
Corresponding to the method for refreshing data shown in fig. 1, an embodiment of the present invention further provides a device for refreshing data, as shown in fig. 6, which is a schematic structural diagram of a device for refreshing data, and the device is applied to a node server. As can be seen from fig. 6, the apparatus includes a refresh request receiving module 61, a judging module 62 and a refresh module 63 connected in sequence, where the functions of the respective modules are as follows:
a refresh request receiving module 61, configured to receive a refresh request for target data;
a judging module 62, configured to determine whether the target data is stored in the local cache;
and a refresh module 63, configured to refresh the target data according to the refresh request if the local cache stores the target data.
In one possible implementation, the determining module 62 is further configured to: acquiring an index directory of cache data in a local cache; searching the index of the target data from the index directory; and determining whether the target data is stored in the local cache or not according to the index searching result of the target data.
In another possible implementation, the refresh module 63 is further configured to: and if the local cache is determined not to store the target data, returning the refreshing success.
In another possible implementation, the determining module 62 is further configured to: acquiring an index directory of cache data in a local cache through a preset refreshing proxy service and a cache service corresponding to the local cache; the refreshing proxy service runs on the node server, is in communication connection with the cache service, and is used for generating an index directory of the cache data.
In another possible implementation, the determining module 62 is further configured to: when monitoring that the refreshing proxy service is started, establishing communication connection between the cache service and the refreshing proxy service; through the caching service, the index directory of the cached data in the local cache is synchronized to the refresh agent service in a heartbeat manner.
