Fig. 5 is the flow diagram that machine number generates in this specification one embodiment, as shown in figure 5, this specification one Destination client can be linked to the journey of distributed system when destination client (application server) starts in a embodiment On sequence coordination service component such as ZooKeeper.If the client in distributed system is in the machine number root node of ZooKeeper It registered, then ZooKeeper can generate a lasting node of sequence for registered client.In the process of creation node In, ZooKeeper can add automatically the numeric suffix of a monotone increasing after the node name of creation, as new node name, And there is ZooKeeper the characteristic of the lasting node of sequence can always exist that is, after node creation, will not be because of client session It fails and deletes.

In this specification one embodiment, destination client can be detected under the machine number root node of ZooKeeper is It is no to register, i.e., whether there is the registration information of destination client under the machine number root node of detection ZooKeeper.As shown in figure 3, It may include machine number root node in the lasting node of the sequence of ZooKeeper, can store in machine number root node registered The serial number of client and the corresponding node of client.The serial number of the machine number root node of two clients is only illustrated in Fig. 3 It above calls time, the lasting node of the sequence of practical ZooKeeper can store multiple, not illustrate specifically in Fig. 3.If target is objective Family end registered under the machine number root node of ZooKeeper, then can directly obtain under the machine number root node of ZooKeeper The serial number in the lasting node of the corresponding sequence in destination client is taken, it can be raw according to the serial number in the lasting node of the sequence got At the machine number of destination client.Such as: machine of the serial number as destination client in the lasting node of the sequence that can be will acquire Serial number in device number, or the lasting node of sequence that will acquire is converted into target customer according to preset machine number coded format The machine number at end.If detecting, destination client registered not under the machine number root node of ZooKeeper, i.e., There is no the registration information of destination client under the machine number root node of ZooKeeper, it may be said that bright destination client is for the first time Generate machine number.The lasting node of sequence can be created under the machine number root node of ZooKeeper, and according to the suitable of creation The corresponding machine number in the corresponding serial number gencration destination client of the lasting node of sequence.Likewise, can also be lasting by the sequence of creation Machine number of the serial number of node as destination client, or by the serial number of the lasting node of the sequence of creation according to preset machine Number coded format is converted into the machine number of destination client.

In this specification one embodiment after getting the machine number of destination client, which will not usually occur Therefore variation in the generating process of Data Identification, can only obtain the machine number of a destination client, will acquire The machine number of destination client saves.It, can when generating the identification marking of other Data Identification objects using the destination client It, using the machine number of the destination client got for the first time, does not need that ZooKeeper is recycled to reacquire with directly.

Further, it is also possible to obtain the machine time of destination client using ZooKeeper, such as it is in detection destination client When no registered in the machine number root node of ZooKeeper, if destination client has been registered, ZooKeeper can use The machine time of destination client is recorded, if destination client is not registered, the sequence that can create destination client is lasting Node, and record the machine time of destination client.

This specification one embodiment generates machine number using the lasting node self-adapting of the sequence of ZooKeeper, exempts from The complexity of human configuration machine number is gone, and the limitation that the quantity for configuring the client of machine number is not certain, method is simple, Strong applicability.

Fig. 6 is the flow diagram that sequence number mark generates in this specification one implementation, as shown in fig. 6, in above-mentioned reality On the basis of applying example, in this specification one embodiment, the machine time based on the destination client generates the number According to the corresponding sequence number mark of mark object, comprising:

Judge whether the machine time and the historical machine time are identical；

Specifically, the time precision in this specification embodiment can be set to millisecond, the same client in one millisecond Identification marking may be generated for multiple Data Identification objects.The machine time and destination client for obtaining destination client exist Machine time when generating the identification marking of Data Identification object (i.e. historical data mark object) i.e. historical machine when Between, compare machine time and whether the historical machine time is identical.The millisecond number and history machine in machine time can specifically be compared Whether the millisecond number in the device time is identical, such as: when the current millisecond number obtained in Fig. 6 can be expressed as the machine of destination client Between millisecond number, last time millisecond number can be expressed as the millisecond number in the historical machine time.If when machine time and historical machine Between it is consistent, i.e., current millisecond number is identical as last time millisecond number, it can be said that generation time and last time that bright sequence number at this time identifies The sequence number of a upper Data Identification object can be identified and increase predetermined sequence value by the generation time consistency of sequence number mark, Generate the sequence number mark of current Data Identification object.If machine time and historical machine Time Inconsistency, i.e., current millisecond It is several not identical as last time millisecond number, then illustrate the Time Inconsistency for generating time and the generation of last time sequence number of sequence number at this time, The sequence number that this cannot be generated according to the create-rule that last time sequence number identifies identifies.In this specification embodiment, in machine When time and historical machine Time Inconsistency, the sequence number of current Data Identification object can be identified at the beginning of being set as sequence number Initial value, sequence number initial value can be set to 0 or other numerical value.

Such as: corresponding identification marking if desired is generated to Data Identification object A using on destination client, obtains target The millisecond number of the current machine time of client, that is, current millisecond number and destination client are generating Data Identification object A Previous number according to mark object B the identification marking corresponding historical machine time millisecond number, that is, last time millisecond number.Judgement is worked as Whether preceding millisecond number is equal to last time millisecond number can be by the sequence number mark in the identification marking of Data Identification object B if being equal to Know the sequence number mark a that b increases predetermined sequence value c as Data Identification object A.As shown in fig. 6, sequence number mark also can be used Knowledge=(sequence number mark+1) % (2^M) calculates the sequence number mark of Data Identification object A, wherein " % " indicates modulus calculating, M It can indicate the digit of pre-set sequence number mark.Sequence number mark in formula in right side of the equal sign bracket can indicate The sequence number mark of one Data Identification object is that the sequence number in the identification marking of Data Identification object B identifies b, left side of the equal sign Sequence number can indicate current Data Identification object sequence number mark i.e. Data Identification object A sequence number identify a.When So, sequence number mark=sequence number mark+1 calculation method can also directly be used to generate the sequence number of Data Identification object A Mark, " sequence number mark+1 " also can be used " sequence number mark+other numerical value " and calculated.If judging current millisecond number not Equal to last time millisecond number, then can set the sequence number of Data Identification object A mark to 0,0 can indicate sequence number mark Initial value.

As shown in fig. 6, in this specification one embodiment, it is described that institute is generated according to the machine time of the destination client State the corresponding sequence number mark of Data Identification object, further includes:

Such as: after generating the sequence number mark of Data Identification object A, it can be determined that such as current milli of current machine time The sequence number generated in number of seconds identifies whether to be more than preset threshold, if being more than, the sequence number mark generated is it is possible that weight It is multiple.Preset threshold can be set to 2^M, and M can indicate the digit of sequence number mark.In this specification one embodiment, sentencing After the sequence number generated in the machine time such as current millisecond number for breaking current identifies more than preset threshold, next milli can be clogged to Number of seconds updates machine time i.e.: can wait 1 millisecond, obtain the machine time of the destination client after waiting 1 millisecond, at this time The millisecond number for updating machine time is equal to current millisecond number+1.It is corresponding that Data Identification object is generated based on updated machine time Sequence number mark, updated machine time may be considered first time formation sequence number mark, therefore, the sequence generated at this time Row number mark can be the initial value of sequence number mark.Meanwhile as shown in fig. 6, can be with the real-time update historical machine time Last time millisecond number is updated, in order to be next Data Identification object formation sequence number mark.

In this specification one embodiment, judge that the sequence number generated in current machine time such as current millisecond number identifies Whether be more than preset threshold method may include:

Specifically, if generating sequence using the mode that the sequence number mark of a upper Data Identification object increases predetermined sequence value When row number identifies, then it may determine that whether the value of the sequence number mark of current Data Identification object is greater than the side of preset threshold Formula, judges the sequence number generated in current machine time (such as: current millisecond number) identifies whether to be more than preset threshold.If current The value of sequence number mark of Data Identification object be greater than preset threshold, then can determine the sequence generated in current machine time Row number identifies more than preset threshold.If the mode that the value for using sequence number to identify carries out modulo operation with preset threshold generates When sequence number identifies, then it can be taken by the value for judging that the sequence number of current Data Identification object identifies with preset threshold Whether the result of modular arithmetic is 0, judges the sequence number that current machine time generates identifies whether to be more than preset threshold.If current Data Identification object sequence number mark value and preset threshold to carry out the result of modulo operation be 0, then can determine current Machine time in generate sequence number identify more than preset threshold.

In this specification embodiment, the coding mode of sequence number mark can be preset, such as: presetting sequence number mark The digit of knowledge, if the sequence number generated in current machine time identifies more than preset threshold, when illustrating according to current machine Between continue formation sequence number mark when, sequence number mark will appear repetition or beyond pre-set sequence number mark position Number.This specification embodiment can continue formation sequence number mark, by way of waiting one millisecond of update machine time to keep away Exempt from sequence number duplicate identity or the digit beyond pre-set sequence number mark.

The generation method that sequence number identifies in this specification embodiment is specifically introduced below with reference to Fig. 6:

(1) current millisecond number, the last time millisecond number of destination client are obtained.

(2) judge whether last time millisecond number and current millisecond number are consistent, if unanimously going to step (3), if inconsistent go to step (4)。

(3) sequence number mark=(sequence number mark+1) % (2^M).

(4) sequence number mark=0, goes to step (7).

(5) judge sequence number identify whether be equal to 0, if not zero-turn to step (7), if zero-turn to step (6).

(6) if sequence number is identified as 0, illustrate that current millisecond number has overflowed, need to be clogged to next millisecond.

(7) updating last time millisecond number is current millisecond number.

(8) returning to sequence number mark is output sequence number mark.

The method that this specification embodiment provides, is generated based on the machine time of destination client in mode incremented by successively The sequence number of Data Identification object identifies, and it is integrally in be incremented by that the identification marking of the Data Identification object of generation, which is based on time series, Gesture is conducive to follow-up data library index, is able to ascend the efficiency of database retrieval.

Fig. 7 is the flow diagram of clock clawback control in this specification one embodiment, as shown in fig. 7, in above-mentioned reality On the basis of applying example, in this specification one embodiment, the method also includes:

Every preset time obtain the destination client on call time；

Calling time on destination client can indicate that destination client is reported to the time of distributed system, i.e. target visitor Family end reports the current time of the client to distributed system.The upper of a destination client can be obtained every preset time Call time, judge destination client on the size relation of the machine time of destination client that calls time and get.If obtaining The machine time for the destination client got on destination client less than calling time, it can be said that in the presence of bright destination client Clock clawback etc. is abnormal.When clock clawback occurs in destination client, it may result in the machine time based on destination client and generate Time identifier, sequence number mark duplicate, the identification marking for further resulting in the Data Identification object of generation duplicates.
