[0002] With the development of computer software technology, the design of distributed systems has been widely applied in the field of the modern software technology, and the traditional software system also faces new challenges while it is being developed towards distribution. Data storage in a distributed system is dispersed, the traditional method of generating data primary key IDs (Identity Document) is no longer applicable, and a novel way has to be found for data primary key identification generating policy in the distributed system. At present, the mainstream distributed ID generating method is the snowflake algorithm, and the method employs the globally unique 64-digit identification information consisting of 1 bit of sign bit + 41 bits of time stamp + 10 bits of machine code + 12 bits of serial number. The snowflake algorithm solves quite well the problem concerning uniqueness of the global identification information in the distributed system, but its deficiency is also apparent. The 64-bit identification information is superfluous to most software systems, as too much storage space is occupied thereby.

DETAILED DESCRIPTION OF THE INVENTION

[0046] To make more lucid and clear the objectives, technical solutions and advantages of the present application, the present application is described in greater detail below with reference to accompanying drawings and embodiments. As should be understood, the specific embodiments as described here are merely meant to explain the present application, rather than to restrict the present application.

[0047] As can be understood, the wording "or/and" as used in the present application describes the association relation of associated objects, and expresses the existence of three possible relations, for instance, A or/and B can express the three circumstances of the single existence of A, the simultaneous existence of A and B, and the single existence of B. The sign "/" generally expresses the relation of "or" between the associated objects before the Date Recue/Date Received 2022-03-17 sign and after the sign.

[0048] The data object identification generating method provided by the present application is applicable to the application environment as shown in Fig. 1-1. In the application environment are included terminal 102, distributed system 104, network 106 and ID
server 108.

[0049] Terminal 102 can be, but is not limited to be, a mobile phone 102, a notebook computer 1024 and a personal computer 1026, etc.; as a matter of fact, the user can apparently further use one of electronic equipments of the following types: panel equipments, notebook computers, personal digital assistants (PDAs), and wearable equipments (such as smart goggles, smart watches), etc., to which no restriction is made by the present application. Distributed system 104 includes servers of n number of computer rooms, the number of n is determinable according to actual circumstances, each computer room contains one or more server(s), the numbers of servers contained in different computer rooms (such as computer room 1 and computer room n) can be identical or different. Each server can be embodied as an independent server or a server cluster consisting of a plurality of servers.

[0050] Network 106 is employed to realize network connection between terminal 102 and distributed system 104, between distributed system 104 and ID server 108, and so on, and can include plural types of wired or wireless networks. In one embodiment, network 106 can include such near field communication networks as Bluetooth, WIFI, and ZigBee. In another embodiment, network 106 can include such remote communication networks as a public switched telephone network (PSTN) and the internet. Of course, it is also possible for network 106 to simultaneously include a near field communication network and a remote communication network.

[0051] ID server 108 can be embodied as an independent server or a server cluster consisting of Date Recue/Date Received 2022-03-17 a plurality of servers. At the same time, ID server 108 is equipped with a storage device for storing and updating in real time sequence values of recognizing identifications as generated.

[0052] During the process of operation, the server in distributed system 104 can request ID server 108 to generate a recognizing identification for a data identification object, and ID server 108 for providing the service to generate globally unique identifications can operate a certain application program to determine a current time stamp, to obtain a current sequence value to which the current time stamp corresponds according to the current time stamp, and to generate the recognizing identification for the data identification object according to the current time stamp and the current sequence value, in which the current time stamp is a date format string of the current time, thusly, it is made possible to reduce the bit number of the generated recognizing identification, and save storage space.

[0053] The data object identification generating method provided by the present application is also applicable to the application environment as shown in Fig. 1-2. In the application environment are included terminal 102, distributed system 104, network 106 and storage equipment 110. Reference can be made to the descriptions of terminal 102, distributed system 104 and network 106 in Fig. 1-1 for terminal 102, distributed system 104 and network 106 in Fig. 1-2, and no repetition is made in this context. Storage equipment 110 can include Redis cache servers or a Redis distributed cache server cluster, and m in Fig.
1-2 is the number of the Redis cache servers. Specifically, in response to an identification generating request of terminal 102, the server in distributed system 104 can determine a current time stamp, base on the current time stamp to request a current sequence value to which the current time stamp corresponds from storage equipment 110, receive the current sequence value returned by storage equipment 110, and generate a recognizing identification for a data identification object in a distributed system according to the current time stamp and the current sequence value, in which the current time stamp is a date format string of the current time, thusly, it is made possible to reduce the bit number Date Recue/Date Received 2022-03-17 of the generated recognizing identification, and save storage space. The mode in Fig. 1-2 is to integrate the service to generate globally unique identifications into the distributed system, in comparison with the mode in Fig. 1-1, the cache cluster of the existing business system is utilized, and deployment cost is saved; at the same time, every server in the distributed system can generate recognizing identifications, whereby concurrency rate can be enhanced.

[0054] In one embodiment, as shown in Fig. 2, there is provided a data object identification generating method, and the method is explained with an example of its being applied to the server in the distributed system in Fig. 1-2, to comprise the following steps.

[0055] Step 202 - determining a current time stamp, wherein the current time stamp is a date format string of a current time.

[0056] Here, the bit number of the date format string is usually 14 bits, namely including 4 bits of year field, 2 bits of month field, 2 bits of date field, 2 bits of hour field, 2 bits of minute field and 2 bits of second field. The bit number of the date format string can also be 17 bits, namely including 4 bits of year field, 2 bits of month field, 2 bits of date field, 2 bits of hour field, 2 bits of minute field, 2 bits of second field and 3 bits of millisecond field.
As required, the date format string can as well be of any other bit number. In comparison with the 41 bits of time stamp in the snowflake algorithm, the bit number of the current time stamp is significantly reduced.

[0057] Specifically, the server can determine the current time stamp on receiving an identification generating request. The server(s) for generating the recognizing identification of the data identification object in this embodiment can be the one or more server(s) in a distributed system.

[0058] Step 204 - obtaining a current sequence value to which the current time stamp Date Recue/Date Received 2022-03-17 corresponds according to the current time stamp, wherein the current sequence value is a numerical value obtained by updating a sequence value to which the current time stamp corresponds.

[0059] Different data objects to which the same and single time stamp corresponds have different sequence values. The mode of updating a sequence value to which the current time stamp corresponds is generally to perform a progressively increasing operation or a progressively decreasing operation on the sequence value. The current sequence value is different in relation to sequence values already allocated to other data objects within the current time stamp.

[0060] Specifically, the server can base on the current time stamp to directly obtain the current sequence value to which the current time stamp corresponds, or request to obtain the current sequence value to which the current time stamp corresponds from any other equipment (such as storage equipment 110 in Fig. 1-2).

[0061] Step 206 - generating a recognizing identification for a data identification object in a distributed system according to the current time stamp and the current sequence value.

[0062] Here, the data identification object is a data object for which a recognizing identification is to be generated. The recognizing identification here generally indicates a data primary key ID.

[0063] Specifically, the server obtains the data identification object and generates the recognizing identification by joining the current time stamp and the current sequence value.

[0064] In the aforementioned data object identification generating method, a current time stamp is determined, the current time stamp is a date format string of a current time, a current Date Recue/Date Received 2022-03-17 sequence value to which the current time stamp corresponds is obtained according to the current time stamp, the current sequence value is a numerical value obtained by updating a sequence value to which the current time stamp corresponds, and a recognizing identification is generated for a data identification object in a distributed system according to the current time stamp and the current sequence value. Since the recognizing identification of the data identification object is generated according to the current time stamp and the current sequence value to which the current time stamp corresponds, and the current time stamp is the date format of the current time, it is thusly made possible to reduce the bit number of the generated recognizing identification, and save storage space.

[0065] In one embodiment, as shown in Fig. 2, there is provided a data object identification generating method, and the method is explained with an example of its being applied to the server in the distributed system in Fig. 1-2, to comprise the following steps.

[0066] Step 302 - determining a current time stamp, wherein the current time stamp is a date format string of a current time.

[0067] Step 304 - obtaining machine ownership information of a target server or/and a business type coding field of the data identification object, wherein the target server is a server to which the data identification object corresponds.

[0068] Here, the server to which the data identification object corresponds usually indicates a server employed to generate the recognizing identification of the data identification object, according to requirements, the server can also be a server that generates or stores the data identification object.

[0069] The machine ownership information usually indicates geological ownership information, for instance, to which region or which computer room the ownership pertains, and the machine ownership information can also be administrative ownership information, for Date Recue/Date Received 2022-03-17 instance, to which organization or unit the ownership pertains. Since the number of pieces of the machine ownership information is usually less than the number of machine (server) codes, for example, the number of computer rooms is less than the number of servers, so the machine ownership information occupies more less bit number as compared with machine codes in the snowflake algorithm.

[0070] Specifically, the server obtains the machine ownership information of the target server and the business type coding field of the data identification object, alternatively the server obtains the machine ownership information of the target server, further alternatively the server obtains the business type coding field of the data identification object. Here, the server can be the same server as the target server, and can also be different from the target server.

[0071] Step 306 - obtaining a current sequence value to which the current time stamp corresponds according to the current time stamp, wherein the current sequence value is a numerical value obtained by updating a sequence value to which the current time stamp corresponds.

[0072] Reference can be correspondingly made to the aforementioned descriptions of steps 202 and 204 for steps 302 and 306 in this embodiment, and no repetition is made in this context.

[0073] Step 308 -joining to obtain the recognizing identification of the data identification object according to the current time stamp and the current sequence value, and according to the machine ownership information or/and the business type coding field.

[0074] Specifically, the server can join to obtain the recognizing identification of the data identification object according to the current time stamp, the current sequence value, the machine ownership information and the business type coding field, alternatively the Date Recue/Date Received 2022-03-17 server joins to obtain the recognizing identification of the data identification object according to the current time stamp, the current sequence value and the business type coding field, further alternatively the server joins to obtain the recognizing identification of the data identification object according to the current time stamp, the current sequence value and the machine ownership information.

[0075] Use of the solution of this embodiment can further economize on the storage space, at the same time, it is made possible to base on the machine ownership information to recognize whence the recognizing identification is generated, to base on the business type coding field to recognize for which business type of a data object the recognizing identification is used, and to facilitate locating and checking online problems.

[0076] In one of the embodiments, the machine ownership information is a computer room coding field of a computer room in which the target server resides, and correspondingly, the recognizing identification of the data identification object is joined to be obtained according to the current time stamp and the current sequence value, and according to the computer room coding field or/and the business type coding field.

[0077] The bit number of the computer room coding field is determinable as practically required, for instance, it can be 4 bits.

[0078] In one of the embodiments, the data object identification generating method of the present application can further comprise the step of: performing Hash calculation on the computer room coding field, and obtaining a computer room Hash coding field, in which case the recognizing identification of the data identification object is joined to be obtained according to the current time stamp and the current sequence value, and according to the computer room Hash coding field or/and the business type coding field.

[0079] In one of the embodiments, as shown in Fig. 4, the step of obtaining a current sequence Date Recue/Date Received 2022-03-17 value to which the current time stamp corresponds according to the current time stamp can include the following steps.

[0080] Step 402 - sending a sequence value obtaining request to a storage equipment, wherein the sequence value obtaining request carries therewith the current time stamp.

[0081] Here, the storage equipment can be used to store the current sequence value and perform data update in real time. The storage equipment can include Redis cache servers or a Redis distributed cache server cluster, in which Redis is a Key-Value database. Since the Redis cache server executes by a single thread, there hence appears no circumstance in which other instructions are concurrently executed while a single instruction is being executed. This feature ensures that completely different numerical values are obtained by repeatedly executing an update instruction, at the same time, Redis is directed to pure memory operation, so it possesses extremely high reading efficiency. According to requirements, the storage equipment can also be embodied as any other distributed lock system.

[0082] In addition, the distributed cache cluster is capable of supplying higher concurrent accessing efficiency relative to a relational database. Moreover, the use of a Redis distributed cache server cluster can rely upon the cache cluster of an existing distributed system, so that deployment cost is saved.

[0083] Specifically, the server can send incrby "ID key" command to the Redis distributed cache server cluster, after having received the command, the Redis cluster performs +1 on the numerical value to which the designated ID key corresponds, and returns the auto-incremented numerical value, in which ID key is the name of the cache key of stored IDs defined in unique ID service, and key is constituted by a self-defined prefix + 14 bits of time stamp, e.g., SN GID 20190701010101. Self-defined prefixes or suffixes can be added before or after the 14 bits of time stamp, so as to differentiate primary keys of Date Recue/Date Received 2022-03-17 different business domains.

[0084] Step 404 - receiving the current sequence value to which the current time stamp corresponds returned by the storage equipment.

[0085] Specifically, the server can receive the current sequence value to which the current time stamp corresponds returned by the storage equipment.

[0086] In this embodiment, by employing the mode of uniformly requesting the current sequence value from the storage equipment, it is made possible to guarantee the global uniqueness of the recognizing identification.

[0087] In one of the embodiments, the date format string can be a second-order date format string, and the second-order date format string includes 4 bits of year field, 2 bits of month field, 2 bits of date field, 2 bits of hour field, 2 bits of minute field and 2 bits of second field, totaling 14 bits.

[0088] In this embodiment, the bit number is apparently reduced by employing the 14 bits of time stamp as compared with the 41 bits of time stamp in the snowflake algorithm, but a business system with data volume by the order of hundred millions can be serviced thereby, so that it is made possible to serve business systems with data volumes as large as possible at the same time of reducing the bit number of the recognizing identification.

[0089] In one of the embodiments, the current sequence value is a numerical value obtained by progressively increasing a sequence value to which the current time stamp corresponds by the storage equipment.

[0090] For instance, the first sequence value of the current time stamp is 0, the second sequence value is 1, the third sequence value is 2, sequentially progressively increasing (it is also Date Recue/Date Received 2022-03-17 possible to increase from 1 sequentially progressively), specifically, when the previous sequence value is m, the current sequence value is m+1, where m is a nonnegative integer.
According to requirements, it is further possible to progressively increase any other step.
In addition, step numerical values are adjustable numerical values, for instance, it is possible to anti-increase based on the increasing tendency of the data, in other words, the greater the increasing rate of a data object is, the smaller will be the step numerical value, thusly, it is made possible to avoid leakage of the total data volume due to data identifications.

[0091] The mode of progressively increasing sequence values is employed in this embodiment to update the sequence values, and this mode is both convenient and quick.

[0092] In one of the embodiments, as shown in Fig. 5, the step of obtaining a current sequence value to which the current time stamp corresponds according to the current time stamp can include the following steps.

[0093] Step 502 - sending a sequence value obtaining request to a storage equipment, wherein the sequence value obtaining request carries therewith the current time stamp.

[0094] Step 504 - when it is detected that the sequence value obtaining request is performed with a rollback operation by the storage equipment, obtaining a next time stamp after the time has been waited to have entered a next time.

[0095] Here, the next time stamp is a date format string of the next time;
when there is no usable sequence value within the current time, the sequence value obtaining request is performed with the rollback operation; generally, there is no longer any sequence value usable for generating the recognizing identification within the current time (or in other words, the current time stamp).

Date Recue/Date Received 2022-03-17

[0096] The next time of the current time is determined according to the order of the current time stamp, if time is measured by the order of second, the next time of the current time is the next second relative to the current time, for instance, the current time is 2019, August 7, 1 hour, 1 minute, 1 second, then the next time is 2019, August 7, 1 hour, 1 minute, 2 second. If time is measured by the order of millisecond, the next time of the current time is the next millisecond relative to the current time.

[0097] In one of the embodiments, with respect to the aforementioned circumstance in which the current sequence value is a numerical value obtained by progressively increasing a sequence value to which the current time stamp corresponds by the storage equipment, when Vs > 10Q-1, the sequence value obtaining request is performed with the rollback operation, where Vs indicates the current sequence value, and Q represents a preset sequence value bit threshold. For instance, when the sequence value bit threshold is 3, then the sequence value obtaining request is performed with the rollback operation when Vs > 999. For instance, the maximum sequence value is exceeded when progressive increasing is performed at 2019, August 7, 1 hour, 1 minute, 1 second, that is to say, the current sequence value of the time stamp 20190807010101 exceeds 999, then decrby command is executed to rollback, and it suffices thereafter to perform the progressive increasing operation on the next time (with the corresponding time stamp 20190807010102) one second later.

[0098] In one of the embodiments, the current sequence value is an integer and satisfies O<Vs<10Q-1, where, preferably, 2<Vs<6, and optionally, the sequence value bit threshold is an adjustable parameter.

[0099] Step 506 ¨ taking the next time stamp as a new current time stamp, and returning to step S502.

[0100] Step 508 ¨ receiving the current sequence value to which the current time stamp Date Recue/Date Received 2022-03-17 corresponds returned by the storage equipment.

[0101] Use of the solution of this embodiment depends relatively less on data storage, when data in the sequence value obtaining request is lost, or when there is no sequence value usable to generate the recognizing identification within the current time, it suffices to wait for the coming of the next time, and generation of globally unique identifications is not affected.

[0102] In one of the embodiments, as shown in Fig. 6, the step of generating a recognizing identification for a data identification object in a distributed system according to the current time stamp and the current sequence value can include the following steps.

[0103] Step 602 - when a bit number of the current sequence value is less than the preset sequence value bit threshold, complementing the bit number of the current sequence value to a bit number to which the sequence value bit threshold corresponds, and obtaining a bit-complemented sequence value.

[0104] The maximum bit number of the current sequence value affects the concurrent number of distributed recognizing identifications as generated. In one of the embodiments, the sequence value bit threshold is an adjustable parameter, that is to say, the maximum bit number of the current sequence value is adjustable as practically required.

[0105] Specifically, the bit number of the current sequence value can be complemented to the bit number to which the sequence value bit threshold corresponds by adding zero before the current sequence value. For instance, the sequence value bit threshold is 3 bits, while the current threshold value is 11, with only two bits, then it is required to add zero before 11 before 3 bits can be reached, and the bit-complemented sequence value is 011.

[0106] Step 604 - generating a recognizing identification for a data identification object in a Date Recue/Date Received 2022-03-17 distributed system according to the current time stamp and the bit-complemented sequence value.

[0107] Use of the solution of this embodiment can guarantee consistency in the bit number of the recognizing identifications, and facilitate to locate corresponding information in the recognizing identifications.

[0108] In one embodiment, as shown in Fig. 7, there is provided a data object identification generating method, and the method is explained with an example of its being applied to the server in the distributed system in Fig. 1-2, to comprise the following steps.

[0109] Step 702 - determining a current time stamp and the number of data identification object(s), wherein the current time stamp is a date format string of a current time.

[0110] Step 704 ¨ when the number of data identification object(s) is 1, obtaining a current sequence value to which the current time stamp corresponds according to the current time stamp, wherein the current sequence value is a numerical value obtained by updating a sequence value to which the current time stamp corresponds.

[0111] Step 706 ¨ generating a recognizing identification for the data identification object in a distributed system according to the current time stamp and the current sequence value.

[0112] Step 708 ¨ when the number is greater than 1, obtaining a current sequence value interval to which the current time stamp corresponds according to the current time stamp and the number.

[0113] Specifically, the starting value (namely the minimum value) of the current sequence value interval can be Vs'+K, the terminating value (namely the maximum value) of the current sequence value interval can be Vs'+mK. Vs'is the maximum sequence value to which Date Recue/Date Received 2022-03-17 the current time stamp corresponds before the current sequence value interval to which the current time stamp corresponds is obtained, m represents the number of data identification object(s), and K is an incremental step that is a positive integer.

[0114] Step 710 ¨ generating recognizing identifications for a plurality of data identification objects according to the current time stamp and the current sequence value interval.

[0115] Here, the sequence values to which the plural data identification objects correspond can respectively be Vs1+K, Vs1+2K, , Vs1+mK.

[0116] Use of the solution of this embodiment makes it possible to generate recognizing identifications for plural data identification objects in batches when there are more than one data objects.

[0117] In one of the embodiments, the plural servers included in the distributed system are clock-synchronous, so as to avoid the circumstance of inconsistent time stamps.

[0118] As should be noted, the data object identification generating method in the aforementioned embodiments is explained by way of example of its being applied to the server in the distributed system in Fig. 1-2, however, according to requirements, it is also possible to apply the data object identification generating method in the aforementioned embodiments to the ID server in Fig. 1-1, that is to say, the executing subject of the aforementioned various steps can also be an ID server.

[0119] To facilitate comprehension of the solution of the present invention, the solution according to the present application is described below through a concrete embodiment.
Explanation is made in this embodiment with an example in which the bit number of the current time stamp is 14 bits, the bit number of the computer room Hash coding field is 4 bits, the bit number of the business type coding field is 4 bits, the bit number of the Date Recue/Date Received 2022-03-17 sequence value is 3 bits, and the sequence value is updated by being progressively increased, but such explanation does not constitute any restriction to the solution of the present invention.

[0120] The data object identification generating method of this embodiment is a method of generating distributed unique identifications based on Redis, and the method generates a recognizing identification of a data identification object according to 14 bits of a time stamp and 3 bits of an incremental sequence number (the bit number of the incremental sequence number can be decided by the actual circumstance of the system). In this embodiment, a Redis distributed cache server cluster is constructed to store the incremental sequence number generated at the current timing.

[0121] As shown in Fig. 8, the data object identification generating method of this embodiment comprises the following steps.

[0122] Step 802¨ obtaining a current time stamp.

[0123] Specifically, 14 bits of the time stamp at a current date are obtained, namely 4 bits of year + 2 bits of month + 2 bits of date + 2 bits of hour + 2 bits of minute + 2 bits of second.

[0124] Step 804¨ obtaining 4 bits of a computer room Hash coding field.

[0125] Step 806¨ obtaining 4 bits of a business type coding field.

[0126] The computer room Hash coding field and the business type coding field can be digital strings.

[0127] Step 808 ¨ updating a progressively increased sequence value of the current time stamp in the Redis distributed cache cluster.

Date Recue/Date Received 2022-03-17

[0128] Specifically, the server can send a progressively increased sequence value obtaining request carrying with the current time stamp to the Redis distributed cache server cluster, the Redis distributed cache server cluster performs +1 on the progressively increased sequence value to which the current time stamp corresponds, and returns the auto-incremented numerical value.

[0129] Step 810¨ detecting whether the progressively increased sequence value is 3 bits, if yes, entering step 814, if not, entering step 812.

[0130] Step 812¨ complementing the progressively increased sequence value to 3 bits by adding zero before the progressively increased sequence value.

[0131] Step 814 ¨ joining the current time stamp, the computer room Hash coding field, the business type coding field, and the progressively increased sequence value, and obtaining a recognizing identification.

[0132] With respect to the progressively increased sequence value complemented with bit in step 812, what are joined are the current time stamp, the computer room Hash coding field, the business type coding field, and the bit-complemented, progressively increased sequence value.

[0133] The arrangement order of the current time stamp, the computer room Hash coding field, the business type coding field, and the progressively increased sequence value is determinable as practically required, for instance, it can be that the computer room Hash coding field is added after the current time stamp, the business type coding field is added after the computer room Hash coding field, and the progressively increased sequence value is added after the business type coding field, thusly, it is made possible to join to form a recognizing identification with 25 bits of characters, namely a currently generated Date Recue/Date Received 2022-03-17 globally unique ID.

[0134] Through the mode of time stamp + progressively increased sequence value to generate the recognizing identification in this embodiment, it is not only made possible to guarantee the global uniqueness of the recognizing identification, but also to reduce the data bit number of the recognizing identification to the maximum extent. At the same time, the use of Redis cache to store the progressively increased sequence value guarantees the global uniqueness while also guarantees relatively higher reading efficiency. Through the 4 bits of business type coding from the fifteenth bit to the eighteenth bit, it can be quickly located from which computer room the recognizing identification is generated, and through the 4 bits of business type code from the nineteenth bit to the twenty-second bit, it can be quickly recognized for which business type the recognizing identification is used.

[0135] As should be understood, although the various steps in the flowcharts of Figs. 2-8 are sequentially displayed as indicated by arrows, these steps are not necessarily executed in the sequences indicated by arrows. Unless otherwise explicitly noted in this paper, execution of these steps is not restricted by any sequence, as these steps can also be executed in other sequences (than those indicated in the drawings). Moreover, at least partial steps in Figs. 2-8 may include plural sub-steps or multi-phases, these sub-steps or phases are not necessarily completed at the same timing, but can be executed at different timings, and these sub-steps or phases are also not necessarily sequentially performed, but can be performed in turns or alternately with other steps or with at least some of sub-steps or phases of other steps.

[0136] In one embodiment, as shown in Fig. 9, there is provided a data identification object identifying device that comprises: a time stamp determining module 902, a sequence value obtaining module 904 and an identification generating module 906, of which

[0137] the time stamp determining module 902 is employed for determining a current time stamp, Date Recue/Date Received 2022-03-17 wherein the current time stamp is a date format string of a current time;

[0146] In one of the embodiments, the current sequence value is a numerical value obtained by progressively increasing a sequence value to which the current time stamp corresponds by the storage equipment.

[0147] In one of the embodiments, when it is detected that the sequence value obtaining request is performed with a rollback operation by the storage equipment, the time stamp determining module 902 obtains a next time stamp after the time has been waited to have entered a time next to the current time, wherein the next time stamp is a date format string of the next time, and, when there is no usable sequence value within the current time, the sequence value obtaining request is performed with the rollback operation; and takes the next time stamp as a new current time stamp, and executes the process of sending a sequence value obtaining request to a storage equipment.

[0148] In one of the embodiments, when Vs > 10Q-1, the sequence value obtaining request is performed with the rollback operation, where Vs indicates the current sequence value, and Q represents a preset sequence value bit threshold.

[0149] In one of the embodiments, when a bit number of the current sequence value is less than the preset sequence value bit threshold, the identification generating module complements the bit number of the current sequence value to a bit number to which the Date Recue/Date Received 2022-03-17 sequence value bit threshold corresponds, and obtains a bit-complemented sequence value; and generates a recognizing identification for a data identification object in a distributed system according to the current time stamp and the bit-complemented sequence value.

[0150] In one of the embodiments, the bit number of the current sequence value is complemented to the bit number to which the sequence value bit threshold corresponds by adding zero before the current sequence value.

[0151] In one of the embodiments, the data identification object identifying device of the present application can further comprise a number determining module for determining the number of the data identification object(s); when the number is greater than 1, the sequence value obtaining module 904 can be further employed for obtaining a current sequence value interval to which the current time stamp corresponds according to the current time stamp and the number; and the identification generating module 906 can be further employed for generating recognizing identifications for a plurality of data identification objects according to the current time stamp and the current sequence value interval.
