Description

Cache processing method and device, electronic equipment and storage medium

Technical Field

The present disclosure relates to the field of network technologies, and in particular, to a cache processing method and apparatus, an electronic device, and a storage medium.

Background

Local caching refers to dividing the physical memory local to the client into a part of space for buffering data written back by the client to the server. Therefore, the data written back by the client is not written into the hard disk of the server firstly, but the written back data is written into the local written back cache space firstly, and when the cache space reaches a certain threshold value, the data is written back to the server. So as to greatly reduce the reading and writing pressure of the server and the network load. In current network environments (e.g., e-commerce shopping guide, network transaction, etc.), in order to cope with the high concurrent system operation pressure, a local caching technology is usually used to cache the persistent information into the local memory of the server.

However, in a distributed scenario, there are multiple service instances (multiple service devices) in a cluster, and through the above-described local caching technology, contents stored in local cache spaces of the service instances included in the cluster are updated or invalidated at the same time, so that there is a problem that cached data in the service instances are inconsistent, which causes a phenomenon that user operations are jittered. Thus, in a distributed scenario, the local cache data of the multiple service devices included in the cluster may be inconsistent, which affects the use experience of the user.

As can be seen from the above, when the cache node included in the distributed cache cluster caches the cache resource, the electronic device may preset a cache refresh cycle of the cache node, and determine that an operation cycle of the time wheel is the same as the cache refresh cycle, so that when the cache node stores the target cache resource, a correspondence between the target cache resource associated in the at least one cache node and the target time scale on the time wheel may be established, and thus, when the time wheel runs to the target time scale, the target cache resource associated in the at least one cache node corresponding to the target time scale may be refreshed. In this case, the electronic device may combine the local cache with the time wheel, so that after the correspondence between the target cache resource associated in the at least one cache node and the target time scale on the time wheel is established, it may be ensured that the associated cache resource is synchronously refreshed when the time wheel runs to the target time scale, and a situation that the data resources cached in the plurality of cache nodes included in the distributed cache cluster are inconsistent is avoided.

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, and/or components.

First, an application scenario of the embodiment of the present disclosure is described.

The cache processing method of the embodiment of the disclosure is applied to a scene in which a distributed cache cluster performs local caching. In the related art, in order to deal with system cache pressure caused by high concurrency, a local cache technology is generally used for caching persistent information in a memory local, but in a distributed cache cluster scene, a plurality of cache nodes (i.e., service instances) exist in a cache cluster, and a conventional local cache scheme cannot guarantee that resources cached locally by each cache node in the cache cluster are simultaneously invalidated (updated or deleted, etc.), so that a problem that data resources cached by each cache node are inconsistent exists, and a jitter phenomenon (data obtained by a user is inconsistent) may exist in user operation.

In order to solve the above problem, an embodiment of the present disclosure provides a cache processing method, where when a cache node included in a distributed cache cluster caches a cache resource, an electronic device may preset a cache refresh cycle of the cache node, and determine that an operation cycle of a time wheel is the same as the cache refresh cycle, so that when the cache node stores a target cache resource, a corresponding relationship between a target cache resource associated in at least one cache node and a target time scale on the time wheel may be established. Therefore, under the condition that the time wheel runs to the target time scale, the associated target cache resources cached in at least one cache node corresponding to the target time scale can be refreshed. In this case, the electronic device may combine the local cache with the time wheel, so that after the correspondence between the target cache resource associated in the at least one cache node and the target time scale on the time wheel is established, it may be ensured that the associated cache resource is synchronously refreshed when the time wheel runs to the target time scale, and a situation that the data resources cached in the plurality of cache nodes included in the distributed cache cluster are inconsistent is avoided. Therefore, the efficiency of local data caching of a plurality of nodes included in the cluster is improved, and the use experience of a user is improved.

The following provides an exemplary description of a cache processing method according to an embodiment of the present disclosure with reference to the accompanying drawings:

fig. 1 is a schematic diagram of a cache processing system according to an embodiment of the present disclosure, and as shown in fig. 1, the cache processing system may include a cluster 11 and clients 12 (only one client 12 is shown in fig. 1 by way of example, and there may be more clients in a specific implementation). The cluster 11 includes a plurality of nodes, and the cluster 11 may establish a communication connection with the client 12. The cluster 11 and the client 12 may be connected in a wired manner or in a wireless manner, which is not limited in this disclosure.

And the cluster 11 is used for receiving and storing the real-time data information sent by the client 12. For example, the nodes included in the cluster 11 receive the cache resources sent by the client 12, store the cache resources in the nodes, and update the cache resources stored in the nodes when receiving the update resources corresponding to the cache resources.

And the client 12 is used for sending the real-time cache resources to the cluster 11. For example, the client 12 generates data resources in real time according to an operation of a user, and transmits the data resources to nodes included in the cluster 11 to cache the data resources in the nodes.

In an implementation manner, the cluster 11 may be one server, a server cluster composed of a plurality of servers, or a cloud computing service center. The cluster 11 may include a processor, memory, and network interfaces, among others. The plurality of cache nodes included in the cache cluster in the present disclosure may be one server in the cluster 11, or one storage device or one storage module on one server.

In one implementable manner, the client 12 is used to provide voice and/or data connectivity services to users. The client 12 may be variously named, for example, a UE end, a terminal unit, a terminal station, a mobile station, a remote terminal, a mobile device, a wireless communication device, a vehicular user equipment, a terminal agent, or a terminal device, etc.

Alternatively, the client 12 may be a handheld device, an in-vehicle device, a wearable device, or a computer with various communication functions, which is not limited in this disclosure. For example, the handheld device may be a smartphone. The in-vehicle device may be an in-vehicle navigation system. The wearable device may be a smart bracelet. The computer may be a Personal Digital Assistant (PDA) computer, a tablet computer, and a laptop computer.

The cache processing method provided by the embodiment of the present disclosure may be applied to the cluster 11 and the client 12 in the cache processing system shown in fig. 1. The electronic devices to which the present disclosure relates may be the cluster 11 or the client 12. The cache processing method provided by the embodiment of the present disclosure is described in detail by taking an example that the cache processing method of the present disclosure is applied to a cluster in a process of performing local cache by a distributed cache cluster.

After introducing the application scenario and the cache processing system of the embodiment of the present disclosure, the cache processing method provided by the embodiment of the present disclosure is described in detail below with reference to the cache processing system shown in fig. 1.

As shown in fig. 2, a flowchart of a cache processing method is shown according to an exemplary embodiment of the present disclosure. The cache processing method is applied to a distributed cache cluster, the cache cluster comprises a plurality of cache nodes, and cache resources are stored in the cache nodes. The cache processing method may include S201 to S203.

S201, setting a cache refreshing period of a cache node.

Specifically, the cache refresh period is the same as the running period of the time wheel, and the running period of the time wheel includes a plurality of time scales.

Optionally, in a distributed scenario, when the cache cluster caches the cache resource, the cache resource in the cache node may be refreshed when time passes through a cache refresh cycle by presetting a cache refresh cycle of the cache node.

Optionally, one cache refresh cycle may have various durations of 1 minute, 1 hour, 1 day, and the like, and the unit duration corresponding to different cache refresh cycles may be any one of the following unit durations: seconds, minutes, hours.

For example, in the case that the cache refresh period is 1 minute in duration, the corresponding unit duration may be unit second, two adjacent time scales on the corresponding time wheel are unit second, and 60 time scales are included on the time wheel; under the condition that the cache refreshing period is 1 hour, the corresponding unit time length can be unit second or unit minute, two adjacent time scales on the corresponding time wheel are unit second or unit minute, and 3600 time scales or 60 time scales are included on the time wheel; in the case that the buffer refresh period is 1 day, the corresponding unit duration may be unit minute or unit hour, the two adjacent time scales on the corresponding time wheel are unit minute or unit hour, and 1440 time scales or 12 time scales are included on the corresponding time wheel.

S202, establishing a corresponding relation between the associated target cache resources in at least one cache node and the target time scales on the time wheel.

Optionally, when the target cache resource cached in at least one cache node included in the cache cluster has an association relationship, a correspondence relationship may be established between the associated target cache resource in the at least one cache node and the same time scale (i.e., the target time scale) on the time wheel.

It should be noted that, the associated target cache resource in the at least one cache node may be understood as: the cached resources in at least one cache node are the same, or the cached resources have a corresponding relationship.

Optionally, the time wheel is predetermined, the set cache refresh period of the cache node corresponds to the time wheel, that is, the cache refresh period is determined as a time period on the time wheel, and the time scale on the time wheel is determined according to the unit duration corresponding to the cache refresh period.

S203, under the condition that the time wheel runs to the target time scale, refreshing the associated target cache resources cached in at least one cache node corresponding to the target time scale.

Optionally, after the target cache resource is associated with the target time scale on the time wheel, the time wheel runs continuously with the lapse of time, and when the time wheel runs to the target time scale, the cache resource in the cache node corresponding to the target time scale may be refreshed.

Optionally, when the time wheel runs to the target time scale, it is detected whether the associated target cache resource cached in the at least one cache node corresponding to the target time scale needs to be updated, and when the target cache resource needs to be updated, the target cache resource cached in the at least one cache node is refreshed.

The technical scheme provided by the embodiment at least has the following beneficial effects: when the cache node included in the distributed cache cluster caches the cache resource, the electronic device may preset a cache refresh cycle of the cache node, and determine that an operation cycle of the time wheel is the same as the cache refresh cycle, so that when the cache node stores the target cache resource, a corresponding relationship between the target cache resource associated in the at least one cache node and the target time scale on the time wheel may be established, and thus, when the time wheel runs to the target time scale, the target cache resource associated cached in the at least one cache node corresponding to the target time scale may be refreshed. In this case, the electronic device may combine the local cache with the time wheel, so that after the correspondence between the target cache resource associated in the at least one cache node and the target time scale on the time wheel is established, it may be ensured that the associated cache resource is synchronously refreshed when the time wheel runs to the target time scale, and a situation that the data resources cached in the plurality of cache nodes included in the distributed cache cluster are inconsistent is avoided. Therefore, the efficiency of local data caching of a plurality of nodes included in the cluster is improved, and the use experience of a user is improved.

It should be noted that, in the embodiment of the present disclosure, the cache parameter may be a cache key, and the cache key may be a specific key value, which is not specifically limited in the present disclosure.

For example, it may be understood that a plurality of cache locations are included in a cache node, each cache location corresponds to one identifier (i.e., a cache key), and when a cache resource is stored in a corresponding cache location in the cache node, a corresponding relationship between the cache resource and the cache key may be determined.

S302, establishing a corresponding relation between the target cache parameters and the target time scales on the time wheel.

Specifically, the target time scale corresponds to at least one cache parameter, and the at least one cache parameter includes a target cache parameter.

Optionally, after the target cache parameter corresponding to the target cache resource is obtained, the target cache parameter is associated with the target time scale on the time wheel, so that when the time wheel runs to the target time scale, the cache resource corresponding to the target cache parameter can be refreshed.

For example, as shown in fig. 4, for a time scale representation of a time wheel shown in an exemplary embodiment of the present disclosure, the time wheel may be represented by a circular list (clock) or an array representation, and taking a cache refresh period corresponding to the time wheel as 1 day and a unit time length corresponding to the time wheel as 1 hour as an example, 12 time scales are included on the time wheel to represent 12 hours of 1 day. Wherein, the time scale 1 corresponds to a first cache key (i.e. key1) corresponding to the first cache resource; time scale 4 corresponds to the second cache key (i.e., key2) corresponding to the second cache resource, time scale 10 corresponds to the third cache key (i.e., key3) corresponding to the third cache resource, and the fourth cache key (i.e., key4) corresponding to the fourth cache resource. When the time wheel runs to the time scale 1, the first cache resource corresponding to the first cache key can be refreshed; when the time wheel runs to the time scale 4, the second cache resource corresponding to the second cache key can be refreshed; when the time wheel runs to the time scale 10, the third cache resource corresponding to the third cache key and the fourth cache resource corresponding to the fourth cache key may be refreshed.

Further, a process of establishing the corresponding relation between the target cache resource and the target time scale on the time wheel in a more specific manner is provided, so that the electronic equipment can quickly and accurately establish the corresponding relation between the target cache resource and the target time scale.

Optionally, after obtaining the target hash value corresponding to the target caching parameter, establishing a corresponding relationship between the target hash value and the target time scale on the time wheel may determine a corresponding relationship between the target caching parameter and the target time scale.

The technical scheme provided by the embodiment at least has the following beneficial effects: in the process of establishing the corresponding relationship between the target cache parameter and the target time scale on the time wheel, the target cache parameter may be subjected to hash processing to obtain a target hash value corresponding to the target cache parameter, and then the target hash value and the target time scale on the time wheel are established to be in the corresponding relationship, so as to determine the corresponding relationship between the target cache parameter and the target time scale. The method further provides a specific implementation mode for establishing the corresponding relation between the target cache parameter and the target time scale, and the target cache parameter is subjected to Hash processing, so that the cache resource in each cache node in the cache cluster is corresponding to one time scale of the time wheel according to the mode, and the corresponding relation between the cache resource and the time scale on the time wheel can be uniformly established, so that the electronic equipment can quickly and accurately establish the corresponding relation between the target cache parameter and the target time scale.

In an implementable manner, as shown in fig. 6 in conjunction with fig. 2, the method in S203 may specifically include S501-S503.

The technical scheme provided by the embodiment at least has the following beneficial effects: under the condition that the time wheel runs to the target time scale, the electronic equipment can determine at least one cache parameter corresponding to the target time scale from all cache parameter lists by acquiring all cache parameter lists firstly according to the corresponding relation between the cache parameters in all cache parameter lists and the time scale, so that all cache resources corresponding to each cache parameter in the at least one cache parameter can be synchronously refreshed. Further, a specific implementation manner of refreshing the associated target cache resources cached in the at least one cache node corresponding to the target time scale is given, so that the efficiency of refreshing the local cache data of the plurality of nodes included in the cluster is improved.

In an implementation manner, the cache refresh period corresponding to the time wheel is at least one of the following durations: unit minutes, unit hours, and unit days; the unit duration corresponding to the cache refreshing period on the time wheel is any one of the following unit durations: second, minute, hour units; and unit time length corresponds to every two adjacent time scales on the time wheel.

It should be noted that the cache refresh cycle corresponding to the time wheel may also be a preset time length, that is, a time length is preset as the cache refresh cycle corresponding to the time wheel, and the preset time length may not be a unit time length (i.e., a unit minute, a unit hour, a unit day), for example, the preset time length may be: 1 day 5 hours, 2 days 1 hours 30 minutes, etc.

The technical scheme provided by the embodiment at least has the following beneficial effects: the cache refreshing cycle corresponding to the time wheel can be any preset time length, and the unit time length corresponding to the time wheel can also be any preset unit time length, so that various setting modes of the time wheel are provided, and the diversity of the time wheel is improved.

In one practical way, the plurality of time scales included in the time wheel are represented by any one of the following ways: circular lists, arrays.

The technical scheme provided by the embodiment at least has the following beneficial effects: the time scales included by the time wheel can be realized in a circular list or array form, various expression modes of the time wheel are provided, and the diversity of the time wheel is improved.

As can be seen from the above examples, in the existing scheme, in the process of performing local caching in a distributed cache cluster, each cache node in a plurality of cache nodes included in the cache cluster independently refreshes cache contents, so that when cache resources cached by the plurality of cache nodes are associated, part of the cache nodes update the cache resources, and the other part of the cache nodes do not update the cache resources, thereby causing a problem that the cache resources in all the cache nodes included in the cache cluster are inconsistent. According to the method, the distributed cache cluster and the time wheel are combined, the cache keys (cache parameters) corresponding to the cache resources correspond to the time scales on the time wheel through a hash algorithm, so that the cache keys corresponding to the same cache resources in all cache nodes in the cache cluster correspond to the same time scale on the time wheel, the purpose of synchronously refreshing the cache resources is achieved when the time wheel runs to the corresponding time scale, and the problem of inconsistency of the cache resources in all cache nodes in the cache cluster is solved. Therefore, the efficiency of local data caching of a plurality of nodes included in the cluster is improved, and the use experience of a user is improved.
