In distributed cache server, the data of storage are generally deposited in the form of index-data (key-value) Storage, key are generally referred to as indexed, and value is then specific data corresponding with the index.For ease of understanding, it is following will illustrate into Row explanation.

For example, being stored with the personal information of Zhang San in distributed cache server, the personal information of Zhang San specifically includes： Gender, age, date of birth, native place, personal story etc., then above-mentioned key then refer to that Zhang San, value then refer to Zhang San's Personal information.When user wants the personal information of inquiry Zhang San, need to ask the access for carrying " Zhang San " by client It asks and is sent to distributed cache server.

In the embodiment of the present application, cache access agent equipment needs the visit that the application server where handling it receives Ask request, and during handling access request, it is corresponding to count each access index according to received access request Access times.

Specifically, cache access agent equipment handles the access request received especially by following steps：

After receiving access request, search local with the presence or absence of the corresponding temporal cache of the access request；

If in the presence of data cached client is sent to by the access request is corresponding；Otherwise, above-mentioned access request is sent out Distributed cache server is given, it is corresponding data cached to obtain the access request from distributed cache server, and should It is data cached to be sent to client.

Specifically, in the embodiment of the present application, client is taken by calling interface to application corresponding with the interface of calling Business device sends access request, specifically, being the cache access agent equipment transmission access request on the application server.When slow After depositing the access request that access agent equipment receives client transmission, first searches and whether there is the visit in local temporal cache Ask that request is corresponding data cached, specifically, being then to search the access request according to the access index carried in the access request It is corresponding data cached.

If it is corresponding data cached that there are the access requests in the local temporal cache of the cache access agent equipment, This data cached is then sent to client；If the corresponding caching number of the access request is not present in local temporal cache According to the access request being then sent to distributed cache server, to search the access request in distributed cache server It is corresponding data cached, specifically, be then according to the access index carried in the access request in distributed cache server It is corresponding data cached to search the access request, when find the access request it is corresponding data cached after, distributed caching clothes Business device by this it is data cached be sent to the cache access agent equipment, this data cached is sent to by cache access agent equipment Client.

In addition, since distributed cache server belongs to distributed cache server cluster, that is, there is the slow of multiple nodes Deposit server.The corresponding data cached buffer service for being potentially stored in one or more node of different access index On device.For ease of understanding, following to illustrate citing.

For example, distributed cache server includes cache server 1, cache server 2.... and cache server K, Wherein, K is the positive integer more than or equal to 3.Access index 1 (key1) it is corresponding it is data cached be stored on cache server 1, The corresponding data of access index 2 (key2) are stored in cache server 1, on cache server 2.

Therefore, when cache access agent equipment by access request when being sent to distributed cache server, needing should The cache server for the corresponding node of access index that access request is sent in the access request.In the embodiment of the present application, The cache server for being sent to the access request is determined for the ease of cache access agent equipment, in cache access agent equipment In be stored with the cryptographic Hash of the corresponding cache server of each access index.In this way, cache access agent equipment is according to the access Corresponding cryptographic Hash is indexed, determines that the access index needs the cache server being sent to.

The above process describes the detailed process of cache access agent equipment processing access request, and cache access agency sets During standby processing access request, cache access agent equipment can also count each access rope in each setting time length Draw corresponding access times.

Wherein, above-mentioned setting time length can be 1 minute, 2 minutes, the random times length such as 3 minutes, when above-mentioned setting Between the specific size of length can be defined according to practical application scene, the embodiment of the present application is not long to above-mentioned setting time The concrete numerical value of degree is defined.
