Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, and in particular to a distributed identification generation method, device, electronic device and storage medium. Background Art

[0002] In most network services, ID (identity) is usually needed to identify various data objects, such as user accounts, online shopping order numbers, online ticket purchase order numbers, etc.

[0003] In the related art, the ID can be generated using methods such as UUID (Universally Unique Identifier), database primary key auto-increment, and Snowflake algorithm.

[0004] Among them, the purpose of UUID is to allow all elements in a distributed system to have unique identification information, but the ID it generates is unordered, containing letters and numbers, etc., without increment or trend. The ID cannot contain business identifiers and has poor readability. It generates a string, which has poor storage performance and slow query efficiency. The data is too long and is not suitable for storage, which consumes database performance and is not friendly to large distributed systems.

[0005] Based on the method of database primary key auto-increment, taking MySQL (relational database management system) as an example, when creating a new table, specify the primary key to automatically increase and generate in the form of auto_increment, or specify a growth step. This is not applicable in distributed high-concurrency systems. Distributed systems involve sharding, cross-machine and even cross-computer room deployment environments. The database auto-increment method cannot meet business needs. If the database goes down, it cannot continue to be used. At the same time, under the condition of high-concurrency and large-scale access, the database's tolerance is limited and it is difficult to support.

[0006] The ID generated by the snowflake algorithm is 64 bits long, of which the first identifier is not used and marked as 0, the next 41 bits are timestamps, which are used to store the difference in timestamps; the next 10 bits are machine codes, which can identify 1024 machine nodes. If the machine is deployed in a separate computer room (IDC), these 10 bits can be split, for example, 5 bits represent the computer room ID and 5 bits represent the machine ID, so there are 32*32=1024 combinations; the last 12 bits are random sequences, which are used to record millisecond counts. A node can generate 4096 ID numbers. However, this method is highly dependent on the machine clock. If the clock is dialed back, it will cause duplicate ID generation, the system will be abnormal, and the ID cannot be generated anymore, which may cause the system to be unusable.

[0007] In summary, the identifier generation method in the related art cannot generate identifiers in batches and needs to access the database multiple times.

[0008] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0033] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0034] Figure 1A schematic diagram showing an exemplary system architecture to which the distributed identification generation method according to an embodiment of the present disclosure can be applied.

[0035] like Figure 1 As shown, the system architecture may include business applications, identification generation services, distributed application coordination services (Zookeeper), remote dictionary services (Redis, Remote Dictionary Server) and databases (DB, DataBase). Among them, business applications and identification generation services can be configured in terminal devices or in other devices. The present disclosure takes terminal devices as an example for explanation, but the present disclosure is not limited to this.

[0036] The terminal device may be a smart phone, a tablet computer, a portable computer, a desktop computer, a smart speaker, a wearable smart device, a virtual reality device, an augmented reality device, etc., but is not limited thereto.

[0037] In the present disclosure, Figure 1 As shown, business application 1, business application 2, business application 3 and business application 4 can send identification generation requests to the identification generation service respectively. Among them, business application 2 and business application 3 can also send identification generation requests together, for example, business application 1 sends identification generation request 1 to the identification generation service, business application 2 and business application 3 send identification generation request 2 to the identification generation service, and business application 4 sends identification generation request 3 to the identification generation service.

[0038] The identity generation service can obtain each identity generation request of each business application, and each identity generation request includes a business identity corresponding to the business application; the identity generation service can respond to the identity generation request and send a node generation request corresponding to the identity generation request to the distributed application coordination service; the distributed application coordination service can generate a unique node for each identity generation request, for example, generating node 1 for identity generation request 1, generating node 2 for identity generation request 2, and generating node 3 for identity generation request 3. If an identity generation request is received later, node 4 can continue to be generated for the identity generation request; the distributed application coordination service can determine the target node from the existing nodes and lock the target node, and return the number corresponding to the target node to the identity generation service; after returning the number corresponding to the target node, the distributed application coordination service can unlock the target node, for example, delete the target node; after deleting the target node, the distributed application can re-determine a new target node from the existing nodes and can wait in line.

[0039] The identification generation service can obtain the number of the target node. According to the number of the target node, the identification generation service can use the identification generation request corresponding to the target node as the target identification generation request. The target identification generation request is the request that the identification generation service currently needs to execute, wherein the business identifier in the target identification generation request is the target business identifier.

[0040] The identification generation service can query the remote dictionary service and database to obtain the maximum identification number of the previous batch corresponding to the target business identification and the number of number segments for each batch; and return the maximum identification number of the previous batch corresponding to the target business identification and the number of number segments for each batch to the business application corresponding to the target business identification.

[0041] The service application can generate and store the identification interval of the current batch corresponding to the target service identifier according to the maximum identification number of the previous batch corresponding to the target service identifier and the number of number segments of each batch, and the identification interval includes the number of number segment identifiers.

[0042] In the disclosed embodiment, the system architecture may further include a client (not shown in the figure). The user may send an identification acquisition request through the client, and the business application may respond to the identification acquisition request, sequentially acquire identifications from the identification interval of the current batch, and return the identifications to the client.

[0043] If the ratio of the number of used identifiers in the identifier interval of the current batch to the number of identifiers in the identifier interval of the current batch exceeds a preset ratio, the business application can generate a new identifier generation request, and the business application can send a new identifier generation request to the identifier generation service to generate the next batch of identifier intervals.

[0044] It should be understood that Figure 1 The number of business applications, identification generation services, distributed application coordination services, remote dictionary services and databases is merely illustrative, and any number of business applications, identification generation services, distributed application coordination services, remote dictionary services and databases may be used according to actual needs.

[0045] It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principle of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0046] Below, each step of the distributed identification generation method in the exemplary embodiment of the present disclosure will be described in more detail with reference to the accompanying drawings and embodiments.

[0047] Figure 2 is a flow chart of a distributed identification generation method according to an exemplary embodiment. The method provided by the embodiment of the present disclosure can be performed as follows Figure 1The process is executed in the client shown in the figure, but the present disclosure is not limited to this.

[0048] like Figure 2 As shown, the distributed identification generation method provided by the embodiment of the present disclosure may include the following steps.

[0049] In step S202, an identifier generation request is obtained, where the identifier generation request includes a service identifier.

[0050] In the embodiment of the present disclosure, one or more business applications may generate one or more identification generation requests corresponding to the business applications, and each identification generation request includes a business identification (bessiness_flag) for characterizing the business application.

[0051] Among them, the identifier (ID) can be used to represent various data objects, such as a user's account number, an order number for online shopping, and a character number in an online game, etc. The identifier can refer to a number or a string that represents uniqueness.

[0052] The business application may be, for example, a shopping application, a ticket purchase application, etc., which is not limited in the present disclosure. For example, a shopping application may use an identifier to indicate an order number of a user's online shopping.

[0053] In step S204, in response to the identifier generation request, a node corresponding to the identifier generation request is generated, and a target node is locked from existing nodes.

[0054] In the embodiment of the present disclosure, one or more identifier generation requests may be responded to and a node corresponding to each identifier generation request may be generated.

[0055] In the embodiment of the present disclosure, the target node can be locked from the existing nodes. For example, the node with the largest number among the existing nodes can be used as the target node, or the node with the smallest number among the existing nodes can be used as the target node.

[0056] In the disclosed embodiment, the target node is locked, and one of the identifier generation requests may be locked for execution, which can ensure the uniqueness of the identifier generation in the subsequent process.

[0057] In step S206, an identifier generation request corresponding to the target node is obtained as a target identifier generation request, where the target identifier generation request includes a target service identifier.

[0058] In the disclosed embodiment, an identifier generation request corresponding to a target node can be used as a target identifier generation request from one or more identifier generation requests, and subsequently a batch of identifiers can be generated based on the target identifier generation request to ensure the uniqueness of the identifier generation.

[0059] Among them, the service identifier in the target identifier generation request can be used as the target service identifier, and the target service identifier can be used to query the maximum identification number and number segment quantity corresponding to the target service identifier.

[0060] In step S208, the maximum identification number of the previous batch corresponding to the target service identification and the number of number segments of each batch are obtained by query.

[0061] In the disclosed embodiment, the maximum identification number (max_id) of the previous batch and the number of number segments (step) of each batch corresponding to the target service identifier can be obtained from a remote dictionary service or database according to the target service identifier.

[0062] Among them, the remote dictionary service and the database can pre-store multiple service identifiers, the maximum identification number of each batch corresponding to the service identifier, and the number of number segments.

[0063] It should be noted that in the embodiments of the present disclosure, the service identifier, the maximum identification number of each batch corresponding to the service identifier, and the number of number segments may also be stored in other types of memory or database, and the present disclosure does not impose any restrictions on this.

[0064] The number of number segments in each batch can be preset according to actual conditions. For example, the number of number segments in each batch can be set to 10,000, that is, 10,000 identifiers can be generated in each batch, or the number of number segments in each batch can be set separately, which is not limited in the present disclosure.

[0065] Among them, the initial maximum identification number can be set to 0. The maximum identification number of the first batch can be obtained based on the initial maximum identification number and the number of number segments of the first batch. The maximum identification number of the second batch can be obtained based on the maximum identification number of the first batch and the number of number segments of the second batch, and so on.

[0066] In step S210, based on the maximum identification number of the previous batch corresponding to the target service identification and the number of number segments in each batch, an identification interval of the current batch corresponding to the target service identification is generated and stored, and the identification interval includes identifications of the number of number segments.

[0067] In the disclosed embodiment, an identification interval [max_id+1, max_id+step] of the current batch corresponding to the target business identifier can be generated based on the maximum identification number (max_id) of the previous batch corresponding to the target business identifier and the number of number segments (step) of each batch. The identification interval includes step identifiers, and the identification interval of the current batch can be stored in the JVM (Java Virtual Machine). After receiving the user's identification acquisition request, the identifiers can be directly acquired in sequence from the stored identification interval of the current batch, avoiding the situation where the database has to be accessed each time the identifier is acquired, thereby greatly reducing the number of database accesses.

[0068] For example, the maximum identification number of the previous batch corresponding to the target service identification is 10000, and the number of number segments in each batch is 10000. Then the identification interval of the current batch corresponding to the target service identification can be generated as [10001, 20000], which includes 10000 identifications.

[0069] The distributed identifier generation method provided by the embodiment of the present disclosure responds to the identifier generation request, generates a node corresponding to the identifier generation request, locks the target node from the existing nodes, and executes the identifier generation request corresponding to the target node as the target identifier generation request, thereby ensuring the uniqueness of the identifier generation; according to the maximum identifier number of the previous batch corresponding to the target business identifier and the number of number segments in each batch, a batch of identifier intervals can be generated, that is, identifiers can be generated in batches, and after receiving the user's identifier acquisition request, the identifiers can be directly acquired in sequence from the stored identifier intervals of the current batch, without having to access the database each time the identifier is acquired, which greatly reduces the number of database accesses and improves the efficiency of identifier generation.

[0070] Figure 3 is a flowchart of another distributed identification generation method according to an exemplary embodiment.

[0071] In the disclosed embodiment, Figure 2 The difference between the distributed identity generation method shown is that Figure 3 The distributed identifier generation method shown further provides how to respond to the identifier generation request, generate a node corresponding to the identifier generation request, and lock the target node from the existing nodes, that is, provides an embodiment of the above step S204.

[0072] like Figure 3 As shown, step S204 may include the following steps.

[0073] In step S302, in response to the identifier generation request, a node generation request is sent to the distributed application coordination service, so that the distributed application coordination service generates a corresponding node for the identifier generation request, and the distributed application coordination service locks the target node according to the number of the existing node.

[0074] In the embodiments of the present disclosure, reference Figure 1 The identity generation service can respond to the identity generation request and send a node generation request corresponding to the identity generation request to the distributed application coordination service; the distributed application coordination service can generate a unique node for each identity generation request, for example, generate node 1 for identity generation request 1, generate node 2 for identity generation request 2, and generate node 3 for identity generation request 3. If the identity generation request is received later, node 4 can continue to be generated for the identity generation request.

[0075] In the embodiments of the present disclosure, reference Figure 1 , the distributed application coordination service can determine the target node from the existing nodes and lock the target node, and return the number corresponding to the target node to the identity generation service.

[0076] In the disclosed embodiment, the distributed application coordination service may determine a target node from existing nodes and lock the target node, or it may be considered that the target node has obtained a Zookeeper lock.

[0077] For example, the distributed application coordination service can select the node with the largest number from the existing nodes as the target node and lock the target node, that is, select node 4 as the target node and lock node 4. The distributed application coordination service can return the number of node 4 to the identity generation service, and the identity generation service can execute the identity generation request corresponding to node 4.

[0078] It should be noted that in the embodiments of the present disclosure, the node with the smallest number may also be used as the target node, or the node that meets other conditions may be used as the target node, and the present disclosure does not impose any limitation on this.

[0079] In step S304, the number of the target node returned by the distributed application coordination service is received, so that the distributed application coordination service deletes the target node after returning the number of the target node.

[0080] In the disclosed embodiment, after returning the number corresponding to the target node, the distributed application coordination service can unlock the target node, for example, delete the target node; after deleting the target node, the distributed application can re-determine a new target node from the existing nodes and can wait in queue.

[0081] For example, after returning the number of node 4, the distributed application coordination service can unlock node 4, that is, it can delete node 4. After deleting node 4, the distributed application can select the node with the largest number from the existing nodes as the target node again, that is, it can select node 3 as the target node, and can wait in line. After the identification generation request corresponding to node 4 is executed, the number of node 3 can be returned to the identification generation service to execute the identification generation request corresponding to node 3.

[0082] In the disclosed embodiment, the target node can be locked through the distributed application coordination service, and the target identifier generation request corresponding to the target node can be executed subsequently to generate a batch of identifiers to ensure the uniqueness of the identifier generation.

[0083] Figure 4 is a flowchart of another distributed identification generation method according to an exemplary embodiment.

[0084] In the disclosed embodiment, Figure 2 The difference between the distributed identity generation method shown is that Figure 3 The distributed identifier generation method shown further provides how to query and obtain the maximum identifier of the previous batch and the number of number segments of each batch corresponding to the target service identifier, that is, provides an embodiment of the above step S208.

[0085] like Figure 4 As shown, step S208 may include the following steps.

[0086] In step S402, the maximum identification number of the previous batch and the number of number segments of each batch corresponding to the target service identification are queried from the remote dictionary service.

[0087] In the disclosed embodiment, the maximum identification number of the previous batch and the number of segments of each batch corresponding to the target business identifier are queried from the remote dictionary service, and the response speed is fast. If the maximum identification number of the previous batch and the number of segments of each batch corresponding to the target business identifier are not queried in the remote dictionary service, step S404 can be executed; if the maximum identification number of the previous batch and the number of segments of each batch corresponding to the target business identifier are queried in the remote dictionary service, the maximum identification number of the previous batch and the number of segments of each batch corresponding to the target business identifier can be queried from the database, and it is determined whether the maximum identification number of the previous batch and the number of segments of each batch queried from the remote dictionary service are consistent with the maximum identification number of the previous batch and the number of segments of each batch queried from the database. If they are consistent, the maximum identification number of the previous batch and the number of segments of each batch can be returned. If they are inconsistent, the maximum identification number of the previous batch and the number of segments of each batch queried from the database can be used to update the maximum identification number of the previous batch and the number of segments of each batch in the remote dictionary service.

[0088] In the embodiments of the present disclosure, reference Figure 1 There can be one or more remote dictionary services, and data consistency can be ensured between remote dictionary services through data synchronization.

[0089] In step S404, if the maximum identification number of the previous batch and the number of segments of each batch corresponding to the target service identifier are not found in the remote dictionary service, the maximum identification number of the previous batch and the number of segments of each batch corresponding to the target service identifier are queried from the database.

[0090] In the disclosed embodiment, the data stored in the database is complete and comprehensive, and the database may store an identification batch record table. If the above data is not found from the remote dictionary service, the maximum identification number of the previous batch corresponding to the target business identification and the number of number segments of each batch may be found from the database.

[0091] In the embodiments of the present disclosure, reference Figure 1 There can be one or more databases, and the master-slave synchronization between databases can ensure data consistency and avoid data loss.

[0092] In the embodiment of the present disclosure, the design of the database table can be as follows:

[0093] CREATE TABLE`xfyl_service_batch_id_record`(

[0094] `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT `primary key`,

[0095] `bessiness_flag`varchar(128)NOT NULL COMMENT`Business flag`,

[0096] `max_id`bigint(20)NOT NULL DEFULT 1COMMENT`maxid`,

[0097] `step` int(11) DEFAULT NULL COMMENT `step`,

[0098] `yn`tinyint(4)DEFAULT`1`COMMENT` valid identifier 0-invalid 1-valid`,

[0099] `create_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT `create time`,

[0100] `up_time` datatime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATECURRENT_TIMESTAMP COMMENT `update time`,

[0101] PRIMARY KEY(`id`)USING BTREE,

[0102] KEY`idx_xfyl_service_batch_id_record_max_id`(`max_id`)USING BTREE

[0103] )ENGINE=InnoDB AUTO_INCREMENT=21DEFAULT CHARSET=utf8ROW_FORMAT=DYNAMIC COMMENT=`Service batch ID record table`;

[0104] Among them, id is the primary key, bessiness_flag identifies the specific business application, max_id records the maximum identification number of the batch, step indicates the number of number segments in each batch, yn indicates whether the record is valid, create_time indicates the record creation time, and update_time indicates the latest time of each record update.

[0105] In step S406, the maximum identification number of the previous batch corresponding to the target service identification queried from the database and the number of number segments in each batch are synchronized to the remote dictionary service.

[0106] In the disclosed embodiment, the maximum identification number of the previous batch corresponding to the target business identification queried from the database and the number of number segments in each batch are synchronized to the remote dictionary service, which can ensure data consistency. The next time the above data is queried, it can be obtained from the remote dictionary service, which can speed up the response.

[0107] In an exemplary embodiment, the above-mentioned distributed identification generation method may further include:

[0108] In step S408, the maximum identification number of the current batch is obtained according to the maximum identification number of the previous batch and the number of segments of each batch, and the remote dictionary service and database are updated.

[0109] In the disclosed embodiment, the maximum identification number of the previous batch and the number of number segments of each batch may be added together to obtain the maximum identification number of the current batch, and the maximum identification number of the current batch may be saved to the remote dictionary service and database.

[0110] For example, the maximum identification number of the previous batch is max_id, and the number of number segments in each batch is step, then the maximum identification number of the current batch can be updated to max_id=max_id+step.

[0111] Figure 5 is a flowchart of another distributed identification generation method according to an exemplary embodiment.

[0112] In the disclosed embodiment, Figure 2 The difference between the distributed identity generation method shown is that Figure 3 The distributed identifier generation method shown further provides how to query and obtain the maximum identifier of the previous batch and the number of number segments of each batch corresponding to the target service identifier, that is, provides an embodiment of the above step S208.

[0113] like Figure 5 As shown, step S208 may include the following steps.

[0114] In step S502, the maximum identification number of the previous batch and the number of number segments of each batch corresponding to the target service identification are queried from the remote dictionary service.

[0115] Step S502 is similar to step S402, and may refer to the above step S402, which will not be described in detail in the present disclosure.

[0116] In step S504, the maximum identification number of the previous batch and the number of number segments of each batch corresponding to the target service identification are queried from the database.

[0117] In the embodiment of the present disclosure, the maximum identification number of the previous batch and the number of number segments in each batch corresponding to the target business identifier can be queried from the remote dictionary service and the database respectively, and it can be determined whether the queried data are consistent. If not, step S506 can be executed. If consistent, the queried data can be returned.

[0118] In step S506, if the maximum identification number of the previous batch corresponding to the target business identifier and the number of number segments for each batch queried from the remote dictionary service are inconsistent with the maximum identification number of the previous batch corresponding to the target business identifier queried in the database and the number of number segments for each batch, the remote dictionary service is updated using the maximum identification number of the previous batch corresponding to the target business identifier queried in the database.

[0119] In the disclosed embodiment, the remote dictionary service is updated using the maximum identification number of the previous batch and the number of number segments of each batch corresponding to the target service identification queried in the database, so as to ensure the consistency of data.

[0120] In an exemplary embodiment, the above-mentioned distributed identification generation method may further include:

[0121] In step S508, the maximum identification number of the current batch is obtained according to the maximum identification number of the previous batch and the number of segments of each batch, and the remote dictionary service and database are updated.

[0122] Step S508 is similar to step S408, and may refer to the above step S408, which will not be described in detail in this disclosure.

[0123] Figure 6 is a flowchart of another distributed identification generation method according to an exemplary embodiment.

[0124] In the embodiment of the present disclosure, Figure 2 Based on the distributed identity generation method shown, Figure 6 The distributed identification generation method shown may also include the following steps.

[0125] In step S602, an identification acquisition request sent by a client is received.

[0126] In the disclosed embodiment, a user may send an identification acquisition request through a client, and a business application may receive the identification acquisition request.

[0127] For example, when a user uses a shopping application to shop online, after the user pays, an order number needs to be generated for each order. At this time, the order number generation request can be regarded as an identifier acquisition request.

[0128] In step S604, in response to the identifier acquisition request, identifiers are acquired in sequence from the identifier interval of the current batch, and the identifiers are returned to the client.

[0129] In the disclosed embodiment, the business application may respond to the identifier acquisition request, sequentially acquire identifiers from the stored identifier intervals of the current batch, and return the identifiers to the client.

[0130] For example, if the business application has stored 10,000 identifiers, and the stored identifier interval is [10001, 20000], then the identifiers can be obtained in sequence starting from identifier 10001.

[0131] In step S606, if the ratio of the number of used identifiers in the identifier interval of the current batch to the number of identifiers in the identifier interval of the current batch exceeds a preset ratio, a new identifier generation request is generated.

[0132] In the disclosed embodiment, if the ratio of the number of used identifiers in the identifier interval of the current batch to the number of identifiers in the identifier interval of the current batch exceeds a preset ratio, the business application can generate a new identifier generation request, and the business application can send a new identifier generation request to the identifier generation service to generate the identifier interval of the next batch. The identifier generation service can respond to the identifier generation request, generate a node corresponding to the identifier generation request, and lock the target node from the existing nodes; query and obtain the maximum identifier number of the current batch and the number of number segments of each batch corresponding to the target business identifier corresponding to the target node; based on the maximum identifier number of the current batch and the number of number segments of each batch corresponding to the target business identifier, generate and store the identifier interval of the next batch corresponding to the target business identifier, and the identifier interval includes the number of number segments of the identifiers.

[0133] The preset ratio can be set as needed, for example, the preset ratio can be 80%. If the number of used identifiers in the identifier interval of the current batch accounts for more than 80% of the number of identifiers in the identifier interval of the current batch, an asynchronous request can be made to generate the identifier interval of the next batch for subsequent use.

It is easy to understand that the processes shown in the above figures do not indicate or limit the time sequence of these processes.
