Specific implementation mode
Before the scheme that this specification offer is provided, first following optimum ideals are provided in conjunction with traditional technology:
The information exchange figure of distributed transaction processing method shown in FIG. 1 can be as shown in Figure 2.Figure it is seen that Pretreatment stage, the substantially uninevitable dependence of calling of the task manager to each participant.In addition, either existing Presentation stage is still in rollback phase, above-mentioned calling process also not no inevitable dependence.Therefore, in distributed environment, Calling of the task manager between each participant is to may be used what concurrent mode carried out.Namely each branch's affairs are It can be with parallel processing.By above-mentioned parallel form, in the case where participant is more, the time of distributing real time system is simultaneously It will not be linearly increasing.For example, if a service interaction time is T, in the case of having N number of participant, according to tradition Distributing real time system mode, the processing expense in two stages is all NT.And parallel form is used, it being capable of basic guarantee Processing time is T.
With reference to above-mentioned optimum ideals, the scheme provided this specification is described in detail.
The distributed transaction processing method that this specification one embodiment provides can be applied to scene as shown in Figure 3 In, in Fig. 3, operation system is used to, according to service request, distributed transaction is divided into multiple branch's affairs.Branch's thing herein Business can refer to a behavior of distributed transaction.It is with business demand:Come for " transferring accounts 100 yuan to account B from account A " It says, then distributed transaction can be divided into Liang Ge branches affairs, which is respectively used to be handled as follows:“A- 100 " and " B+100 ".Later, multiple branch's affairs of division can be sent to task manager by operation system.Transaction management Device can parse multiple branch's affairs, after receiving above-mentioned multiple branch's affairs with the respective processing of determination Object (e.g., account etc.) and the processing mode to dealing with objects corresponding resource (e.g., account balance, gold etc.).Later, may be used According to process object and processing mode, to determine the dependence between multiple branch's affairs.And according to the dependence, parallel And/or the multiple branch's affairs of serial process.Finally, the processing result information of multiple branch's affairs is returned to industry by task manager Business system.
It should be noted that in Fig. 3, task manager handles branch's affairs particular by participant is called, In, participant can refer to the service that task manager is called when handling branch's affairs.Such as previous example, a participant Financial library A is may be considered, and another participant may be considered financial library B.Specifically, in above-mentioned two branch affairs In processing procedure, task manager can call financial library A to produce 100 yuan from account A, and financial library B can be called to give account B It is transferred to 100 yuan.Account A has just been protected as a result, and has been withholdd adds the consistency of money with account B.In the processing procedure of above-mentioned branch's affairs, If having any exception, unsuccessfully rollback, and feeds back and transfer accounts unsuccessfully.
Fig. 4 is the distributed transaction processing method flow chart that this specification one embodiment provides.The execution of the method Main body can be the task manager in Fig. 3.As shown in figure 4, the method can specifically include:
Step 410, task manager obtains the corresponding multiple branch's affairs of distributed transaction.
In one implementation, distributed transaction can be divided into multiple branches by operation system according to business demand Affairs.It is with business demand:It " transfers accounts 100 yuan to account B from account A, 5 yuan is shared in the benefit to for for account C ", then from account B Distributed transaction can be divided into four branch's affairs, which is respectively used to be handled as follows:“A-100”、 " B+100 ", " B-5 " and " C+5 ".Later, multiple branch's affairs of division can be sent to task manager by operation system.
Step 420, multiple branch's affairs are parsed, with the multiple branch's affairs of determination it is respective process object and it is right Deal with objects the processing mode of corresponding resource.
Process object herein may include the account etc. of user.Corresponding resource is dealt with objects to can include but is not limited to Account balance (also referred to as fund) and gold etc..And may include that resource increases to the processing mode for dealing with objects corresponding resource With resource consumption etc..To deal with objects as account, deal with objects corresponding resource be account balance for for, can be according to right The increase and decrease situation of the account balance of account determines the processing mode to resource.Specifically, when increasing the account balance in account When, can be that resource increases to the processing mode of resource;And when reducing the account balance in account, to the processing mode of resource It can be resource consumption.
Such as previous example, the respective process object of four branch's affairs is respectively:" account A ", " account B ", " account B " and " account C ".Further, since first branch's affairs is used to deduct 100 yuan namely the first point from the account balance of account A Branch affairs are used to reduce the account balance in account A, so it is to the processing mode of resource:" resource consumption ".It similarly can be with Determine that other three branch's affairs are respectively to the processing mode of resource:, " resource increase ", " resource consumption " and " resource increase Add ".
Step 430, according to process object and processing mode, the dependence between multiple branch's affairs is determined.
In one implementation, can be classified to multiple branch's affairs according to processing mode.To branch's affairs After being classified, according to process object, the dependence between different classes of branch's affairs is determined.Specifically, to multiple points Each branch's affairs in branch affairs judge whether branch's affairs are resource to the processing mode for dealing with objects corresponding resource Increase.If so, determining that the classification of branch's affairs is that resource increases class.If not, it is determined that the classification of branch's affairs is money Source consumes class.Increase resource branch's affairs of class, directly can be determined as being not present relying on by branch's affairs of the category and close Branch's affairs of system.To branch's affairs of resource consumption class, judge branch's affairs of the resource consumption class process object whether It is identical to increase the process object of branch's affairs of class with resource.If so, determining that branch's affairs of the resource consumption class are to exist Branch's affairs of dependence.If not, it is determined that branch's affairs of the resource consumption class are that there is no branch's things of dependence Business.
Such as previous example, due to second branch's affairs (the branch's affairs for corresponding to " B+100 ") and the 4th branch's thing Business (the branch's affairs for corresponding to " C+5 ") is " resource increase " to the processing mode for dealing with objects corresponding resource, so can To determine that the classification of the Liang Ge branches affairs increases class as resource.Since first branch's affairs (corresponds to the branch of " A-100 " Affairs) and third branch affairs branch's affairs of (correspond to " B-5 ") it is equal to the processing mode for dealing with objects corresponding resource For " resource consumption ", it is possible to determine that the classification of the Liang Ge branches affairs is resource consumption class.
Increase the Liang Ge branches affairs of class for resource, it may be determined that the Liang Ge branches affairs are that there is no dependences Branch's affairs.To the Liang Ge branches affairs of resource consumption class, due to the processing of third branch affairs and second branch's affairs Object (account B) is identical, it is possible to determine that third branch affairs are branch's affairs there are dependence.And the first point Branch affairs and the process object for the Liang Ge branches affairs that resource increases class are different, so determining that first branch's affairs is not deposit In branch's affairs of dependence.
Step 440, according to dependence, the parallel and/or multiple branch's affairs of serial process.
In one implementation, the branch's affairs that can will be not present dependence are divided into the first grouping, there will be Branch's affairs of dependence are divided into second group.Branch's affairs in the grouping of parallel processing first.Point in the first grouping After branch end of transaction, branch's affairs in parallel processing second packet.
Such as previous example, second branch's affairs, the 4th branch's affairs and first branch's affairs can be divided To the first grouping.Third branch affairs are divided into second packet.Later, second branch's affairs of parallel processing, the 4th Branch's affairs and first branch's affairs.After three branch's end of transaction, processing third branch affairs.This Place, it is understood that be that third branch affairs are serial process.
The distributed transaction processing method provided by this specification above-described embodiment can both improve distributed transaction Treatment effeciency, and can guarantee the correctness of its processing.Such as previous example, in point corresponding to " A-100 ", " B+100 " and " C+5 " The parallel processing of branch affairs elder generation can correspond to later in the case where serial process corresponds to " B-5 " branch's affairs to avoid working as When " B-5 " branch affairs are first handled, if the account balance of account B be 0, can processing failure the problem of.That is, this specification It, can be by way of setting processing sequence, to ensure its processing when the process object of branch's affairs is identical in embodiment Correctness.
It is understood that in the transaction methods that this specification above-described embodiment provides, it is assumed that task manager It is T to call the time of primary service (or participant), and assumes that distributed transaction is divided into N number of branch's affairs.So in N There is no in the case of dependence between a branch's affairs, the processing time expense of distributed transaction is T.And in N number of branch Between affairs there are dependence in the case of, the processing time expense of distributed transaction is 2T.Thus, it is possible to find out, dividing In the case that dependence is not present in cloth affairs, the scheme that this specification provides can be by distributing real time system time control Within the scope of single branch's transaction time, because participant increases will not be increased the entire distributing real time system time Add.Even if in the case of there is dependence between branch's affairs, handling duration is still controllable, and not with participant's popularization And processing time is caused to increase.
