Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the application, feature and advantage to become apparent from, below in conjunction with the drawings and specific embodiments, the application is described in further detail。
Under a lot of application scenarios, it is desirable to respond calling systemic-function in a different manner, or will calling of systemic-function is assigned on different servers, simultaneously when response and distribution request with the concept of weight。Such as, calling response mode A and B two kinds different for identical systemic-function, wherein it is desirable to there is the request of 60% to respond in A mode, and the request of 40% responds in B mode。Or, there is two-server A and B can respond identical system function call, wherein it is desirable to there be 70% call and be responsible for response by server A, and server B is only responsible for other 30% call and respond。In this case, it is possible to thinking that response mode A has higher weight relative to response mode B, same, server A has higher weight relative to server B, because they or the number of times being performed are more, or need to undertake more system function call。
For above-mentioned this demand, the application proposes a kind of simple and effective request processing method, it is possible to according to weight, request is performed different operations, and the operation execution number of times giving the authority to great is more, and it is relatively fewer that the operation that weight is little then performs number of times。
By the examples below the flow process that realizes of herein described method is described in detail。
With reference to Fig. 2, it it is the flow chart of a kind of request processing method described in the embodiment of the present application。
Step 201, for the multiple different operating that same request is corresponding, is respectively provided with the element of various operation respective weights quantity according to the weight size of various operations, the corresponding operation of each element；
The multiple different operating of described same request correspondence refers to, same request may correspond to multiple different operating, but this request only can perform one of which operation。Wherein, described operation can be distribution request, it is also possible to be the request that responds by different way, or other operation。
As an example it is assumed that can perform operation A and B two kinds different for same request, the execution chance of every kind of operation has according to the size of respective weight to be had less more。If weight total score is 10 points, weight shared by A operation is 3 points, weight shared by B operation is 7 points, then the described element being respectively provided with various operation respective weights quantity according to every kind of weight size operated refers to: 3 elements of corresponding A operation setting, these 3 elements all represent with a；Corresponding 7 elements of B operation setting, these 7 elements all represent with b。
So, each element in 10 elements represents an operation altogether, wherein has 3 a elements to represent A operation, namely represents that the weight of A operation is 3, has 7 b elements to represent B operation equally, namely represents that the weight of B operation is 7。
It is further preferred that in actual applications, these elements of above-mentioned setting can the form of array store, because array is relatively simple a kind of storage mode, also very convenient when searching and call these elements。It is of course also possible to store with somewhat complicated chained list or other modes, this is not limited by the present embodiment。
Step 202, when a request is received, randomly draws an element from the element arranged；
Namely for the request received, from all elements of above-mentioned setting, an element is randomly drawed out。In actual applications, various random algorithm is adopted all can to realize, for instance to adopt Jave language to realize, then can directly utilize the random method carried in Jave and randomly draw。
In practical application, it is possible to after the requests have been received, then randomly draw an element from the element arranged；Can also randomly draw in advance, the request then described Elemental partition extracted in advance received to the next one。
Step 203, according to the respective operations representated by the element extracted, performs described respective operations to described request。
Owing to being randomly draw, the element therefore extracted is probably a, it is also possible to b。If element a, then perform A operation；If element b, then perform B operation。From statistical probability, this mode randomly drawed ensure that a request performs the A probability operated and accounts for about 30%, and the probability performing B operation accounts for about 70%, is for same request, and the weight performing A operation is 3, and the weight of execution B operation is 7。
Through test, the method for the above-mentioned this element arranging corresponding number according to weight size can perform different operating according to weight preferably, thus the operation making weight high is more performed chance, the execution chance of the operation that weight is low is then relatively fewer。
As previously mentioned, herein described content is applicable to plurality of application scenes, as request distributed to different server process according to weight, it is also possible to call different systemic-functions for request according to weight, or calling of identical systems function is responded in a different manner, etc.。For various different application scenarios, several processing mode is set forth below, as follows:
1) if each element represents a data base or application server, then described request is performed described respective operations and include: data base or application server that described request is assigned to the representative of described element process。
2) if each element represents a kind of system function call, then described request is performed described respective operations and include: the systemic-function represented for element described in described request call。
3) if each element represents the one request response mode in identical systems funcall, then described request is performed described respective operations and include: respond described request with the response mode that described element represents。
For the above-mentioned three kinds of application scenarios enumerated, in order to make those skilled in the art become more apparent upon present context, citing carries out detailed explanation separately below。
For the 1st) plant processing mode, below concrete execution process to be described according to weight allocation database operation requests。
In this case, it is assumed that described request is database access request or application server access request；
Then described request is assigned to data base that described element represents or application server carries out process and is:
The data base that described database access request is assigned to the representative of described element completes to access accordingly operation, or, the application server storehouse that the request of described application server access is assigned to the representative of described element is completed to access accordingly operation。
It is exemplified below:
In the design of database of the present embodiment, in order to obtain reasonable reliabilty and availability, the scheme in active and standby storehouse will be adopted。
With reference to Fig. 3, it is the deployment architecture figure in a kind of active and standby storehouse described in the embodiment of the present application。
Identical data are preserved in master library and standby storehouse, wherein, the renewal of data is operated and is all completed by master library, master library regularly by the data syn-chronization that changed to on storehouse。Standby storehouse then provides only query capability, thus can to provide, for an identical data acquisition system, the service updating and inquiring about with multiple stage database server, such that it is able to provide service for more user。
In this case, wish that the inquiry request dropping on master library is a little less, or even there is no inquiry request, because master library to undertake all of more newly requested execution, also to be responsible for the data changed to the transmission of standby storehouse simultaneously, so in order to allow master library have more system resource to go to perform to update operation and data simultaneously operating, it is desirable to reduce or shield the inquiry request being assigned to master library, but these inquiry request are sent to standby storehouse, allow standby storehouse complete search and return data。
Scheme based on above-mentioned active and standby storehouse, it is assumed that the total score of weight is 10 points, now with a master library M, two standby storehouse A and B, and wish that master library M undertakes the inquiry request of 20%, namely weight is 2, and each standby storehouse each undertakes the inquiry request of 40%, i.e. weight respectively 4。
The process of data base querying request is as follows:
With reference to Fig. 4, it is the method flow diagram processing data base querying request a kind of described in the embodiment of the present application。
Step 401, creates an array having 10 elements, inserts 2 elements representing master library in this array, and by these 2 element called after M；
Step 402, inserts 4 elements representing standby storehouse A in step 401 in the array created, and by these 4 element called after SA；
Step 403, inserts 4 elements representing standby storehouse B in step 401 in the array created, and by these 4 element called after SB；
After execution of step 401,402 and 403, an array as shown in Figure 5 can be obtained；
Step 404, upsets this array；
Described " upsetting " refers to and is upset by the element position in array, is put on other optional positions by the element on origin-location。Upset each element in array in order that next step randomly draws。Practical application can adopt multiple method upset by the element in array, for instance adopt Jave language realize, then can directly utilize Jave carries upset method。
Step 405, for some inquiry request, from this array, extract an element out at random, then check that this element represents master library M or represents standby storehouse A or B, subsequently inquiry request is assigned to the data base represented described in this element, by this inquiry request of this database response。
There is inquiry request to arrive every time, all can run above-mentioned step 405, from this array, randomly draw out an element, then send the requests to the data base that this element represents。Finding by testing, this method can make the inquiry request being assigned to master library account for about the 20% of total number of request, is assigned to the inquiry request of standby storehouse A and B respectively about 40%。
For the 2nd) plant processing mode, to call different systemic-functions so that concrete execution process to be described according to weight。
In this case, it is assumed that described request is web access requests, system function call two kinds different corresponding to described request be respectively as follows: the web data before calling correcting and call correcting after web data；
The systemic-function then represented for element described in described request call is:
The web data that described element represents is called for described web access requests。
It is exemplified below:
Similar with method shown in above-mentioned Fig. 4, for needing to call the scene of different systemic-functions according to weight, its execution process is held essentially constant, it is only necessary to step 405 slightly modified, is about to distribution inquiry request and is revised as: calls the systemic-function representated by the element extracted in array。So, the number of times that the systemic-function that weight is high is performed is relatively many, and the number of times that the low systemic-function of weight is performed is relatively fewer。
For example, it is assumed that the webpage of a web site is carrying out correcting, in order to not affect the experience of most users, it is desirable to the user to 20% asks the webpage B after returning correcting, and the user of 80% is asked the webpage A before still returning original correcting。Now, same web access requests is called different systemic-functions and refers to: call the webpage A before correcting, still call the webpage B after correcting。For a user, it is not relevant for calling which kind of webpage, but for website developer, it would be desirable that continue to improve the content of webpage by this user feedback of 20%。In this case, utilize the said method just can to the user request call webpage B of 20%, and the user request call webpage A to 80%。
For the 3rd) plant processing mode, concrete execution process to be described according to weight distribution request response mode。
In this case, it is assumed that described request is test request, identical systems funcall corresponding to described request is: generate simulation request according to described test request；
Then each element represents and generates a type of simulation request；
The response mode represented with described element respond described request for:
Generate the simulation request of type representated by described element。
It is exemplified below:
For calling of identical systemic-function, utilize method shown in above-mentioned Fig. 4, it is also possible to respond with different response modes according to weight。Such as, in the performance test of system, need to simulate various types of request with the test system disposal ability to these requests, this just requires first to generate these various types of simulation requests according to test request in test process, and tester wishes that the simulation of wherein 10% is asked as type A, the simulation request of 40% is type B, and the simulation of 50% request is Type C。In this case, when test request is processed, utilize said method, it is possible to generating different types of simulation request according to weight, the element as randomly drawed out represents Type C, then generate the simulation request that type is C。
Additionally, said method is also applied in the scene that other are similar, the application will not enumerate at this。
