[0002] With the development of distributed systems, the number of messages and data in distributed systems has increased dramatically. Therefore, in distributed systems, it is necessary to manage the unique serial numbers corresponding to messages and data.

[0003] In the traditional technology, when the serial number needs to be recycled during the business use process, the developer determines the serial number that is no longer used by the business system in the serial number client, updates the recycled status of the serial number to the database of the serial number server, and marks the status of the serial number to be recycled as recycled in the database. Then, when the serial number client obtains a new serial number, the status mark is checked and the recycled serial number is returned to the serial number client first to avoid reallocation of the used serial number.

[0067] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0068] The serial number recovery method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the sequence number client 102 communicates with the sequence number server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. If the sequence number client 102 monitors that the operation status of the business system meets the preset operation status condition, the sequence number to be recycled is determined in the cached sequence number based on the sequence number identifier; the sequence number identifier indicates that the sequence number is not used; the sequence number client 102 sends the sequence number to be recycled to the sequence number server 104; the sequence number to be recycled is used to store in the recycling cache pool of the sequence number server 104 for the reuse of sequence number resources. Among them, the sequence number client 102 can be deployed in the business system, and each business system interacts with the sequence number server 104 through the sequence number client 102 on the business system when it needs to obtain the sequence number or the sequence number is recycled, so as to obtain the sequence number or recycle the sequence number. The server 104 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0069] In an exemplary embodiment, Figure 2 As shown, a serial number recovery method is provided, which is applied to Figure 1 The serial number client in is taken as an example to illustrate, including the following steps 202 to 204. Among them:

[0070] Step 202: If it is monitored that the running state of the business system meets the preset running state condition, the sequence number to be recycled is determined in the cached sequence numbers based on the sequence number identifier.

[0071] Among them, the serial number identifier represents that the serial number is not used.

[0072] In the embodiment of the present application, the serial number client deployed in the business system monitors the operation status of the business system in real time, and the serial number client is pre-set with preset operation status conditions, which include business system stop, business system restart and business interruption conditions. Among them, business system stop and business system restart are operation and maintenance operations of business system stop or business system restart performed by operation and maintenance personnel on the business system in the scenario where the business system needs system upgrade or system repair. At this time, the business system receives the stop or restart instruction and prepares to stop or restart.

[0073] During the process of stopping or restarting the business system, since the serial number client is deployed in the business system, when the business system stops or restarts, the serial number client will also stop or restart. With the stopping or restarting of the business system, the cache of the serial number client will also be cleared, and the serial numbers obtained by the serial number client for the business system are stored in the cache of the serial number client. Therefore, the serial number client needs to recycle the cached serial numbers in the serial number client cache before the business system stops or restarts.

[0074] First, during the process of the serial number client continuously monitoring the business system in real time, if the running state of the business system is monitored to be in the above-mentioned business system stop, business system restart or business interruption, the serial number client calls the serial number recovery interface, and the serial number recovery interface includes the processing flow of recovering the serial number of the business system. The serial number stored in the serial number client cache has a corresponding serial number identifier. For example, when the business system obtains the serial number from the serial number client based on the business demand, the serial number client stores the obtained serial number sequence (the serial number sequence is a batch of serial number sets corresponding to the number of business demand) in the cache. After some serial numbers in the serial number sequence are used, the business system feeds back to the serial number client a message that the serial number is used, and then the serial number client can modify the serial number representation of the used serial number in the serial number sequence, that is, change the serial number identifier from "serial number not used" to "serial number used". Therefore, the serial number client can determine the unused serial number to be recovered in the cached serial number based on the serial number identifier.

[0075] Step 204, sending the sequence number to be recycled to the sequence number service end.

[0076] The sequence number to be recycled is used to be stored in the recycling buffer pool of the sequence number server for the reuse of sequence number resources.

[0077] In the embodiment of the present application, after the sequence number client determines the sequence number to be recycled in the cached sequence number according to the sequence number identifier, the sequence number client sends the sequence number to be recycled to the sequence number server through the sequence number recycling interface, wherein the sequence number server includes a recycling cache pool for storing the sequence number to be recycled, and then the sequence number resource is reused through the storage of the sequence number to be recycled by the sequence number server. In addition, the recycling cache pool of the sequence number server adopts a cache mechanism to store the sequence number to be recycled in the cache, which can improve the performance of the business system obtaining the sequence number from the sequence number server through the sequence number client compared to adjusting the sequence number status in the database.

[0078] In this embodiment, during the operation and maintenance of the business system, the business system needs to be restarted or a stop operation is triggered. At this time, there is a cached sequence number in the cache of the sequence number client. When the business system triggers the operation and maintenance operation by monitoring, the sequence number to be recycled is determined in the sequence number client cache, and then the sequence number to be recycled is sent to the sequence number server, so that the sequence number server stores the sequence number to be recycled in the recycling cache pool, thereby realizing automatic recycling and backup processing of the sequence numbers to be recycled that are not used by the business system, preventing the loss of unused sequence numbers due to clearing the cache during the restart or stop operation of the business system, improving the utilization rate of sequence number resources, and improving the efficiency of sequence number recycling through automation.

[0079] In an exemplary embodiment, the preset operating state condition includes service interruption, and step 202 includes step 2021. Wherein:

[0080] Step 2021: If a service interruption condition of the service system is monitored, a sequence number to be recycled is determined from the cached sequence numbers based on the sequence number identifier.

[0081] In an embodiment of the present application, when the preset operating status condition is that a business system has a business interruption, for example, taking the business system as an order system as an example, when a business interruption occurs to an order in the current order system, the order has an order number, and the order number is obtained by the business system from the serial number client during the order generation process. At this time, the order number (serial number) may not have completed the order generation due to the business interruption, and the serial number client needs to recycle the unused serial number to be recycled.

[0082] When the serial number client monitors that the operating status of the business system is business interruption, the serial number client can retrieve the serial number used by the interrupted business corresponding to the business interruption status from the cached serial numbers in the cache, determine the serial number corresponding to the interrupted business, and determine whether to determine the serial number as a serial number to be recycled based on the serial number identifier of the serial number corresponding to the terminal business.

[0083] In this embodiment, by determining the sequence numbers to be recycled when the business system is interrupted, unused sequence numbers can be recycled more comprehensively, the utilization rate of sequence number resources can be improved, and the interruption or skipping of sequence numbers in business transaction data can be avoided, thereby ensuring the integrity of business transaction data in the business system.

[0084] In an exemplary embodiment, Figure 3 As shown, step 2021 includes steps 302 to 304. Among them:

[0085] Step 302: If a service operation interruption condition of the service system is monitored, the sequence number status of the service interruption condition is determined.

[0086] In an embodiment of the present application, the serial number client continuously monitors the business system. If a business operation interruption condition of the business system is monitored, the business operation interruption condition is a condition in which the generation process of the transaction order is interrupted when the business transaction of the business system generates a transaction order according to the acquired serial number. At this time, the serial number client first sends a serial number status query request to the business system to determine the serial number status of the serial number corresponding to the business interruption condition, and the serial number status of the serial number includes a serial number available status or a serial number unavailable status.

[0087] Step 304: If the service system feedback message is a sequence number application interruption message, the sequence number state is determined to be a sequence number available state, and the sequence number corresponding to the sequence number application interruption message is sent to the sequence number server through the sequence number recovery interface.

[0088] In the embodiment of the present application, the business system responds to the sequence number status query request of the sequence number client, and the business system queries the business transaction corresponding to the business operation interruption condition to determine the type of business operation interruption condition in the business transaction. If the type of the business operation interruption condition is a sequence number application interruption message, it means that before the sequence number is applied, when generating the transaction order of the business transaction, the transaction order generation fails due to a logical error in the business system, which indicates that the sequence number used when the business operation interruption condition is not applied, and the business system feeds back the sequence number application interruption message to the sequence number client, indicating that the sequence number corresponding to the current business operation interruption condition has not been used. Then, the sequence number client receives the feedback message of the business system, and if the sequence number client determines that the feedback message is a sequence number application interruption message, the sequence number client can determine that the sequence number corresponding to the sequence number application interruption message is not used, indicating that the subsequent business system can continue to use the sequence number corresponding to the sequence number application interruption message when conducting business transactions. Therefore, the sequence number client sends the sequence number corresponding to the sequence number application interruption message to the sequence number server through the sequence number recovery interface, so that the sequence number corresponding to the sequence number application interruption message is recovered to the sequence number server as a sequence number to be recovered.

[0089] In this embodiment, when the business operation interruption condition of the business system is monitored, the serial number status is first determined based on the feedback message of the business system. If the feedback message is a sequence number application interruption message, the serial number status is determined to be a serial number available status. In the scenario where the preset operating status condition is a business operation interruption condition, the unused serial numbers can be recovered to ensure the integrity of the business transaction data.

[0090] In an exemplary embodiment, after step 302, the method further includes step 3021. Wherein:

[0091] Step 3021: If the service system feedback message is a service interruption message, the sequence number status is determined to be a sequence number unavailable state, and the sequence number with the sequence number unavailable state is cached and cleared.

[0092] In the embodiment of the present application, if the type of the business operation interruption condition is a business interruption message, it means that the current business operation interruption condition is a business interruption caused by business reasons. For example, taking the business system as an order system as an example, in business, the order is interrupted due to the user's cancellation of the order or cancellation of the payment, that is, the business is interrupted. At this time, since the business system has completed the generation of the order, it means that the sequence number corresponding to the current business transaction has been used. At this time, the sequence number client determines the sequence number status of the sequence number as the sequence number unavailable state. Therefore, the sequence number client does not need to recycle the sequence number whose sequence number status is the sequence number unavailable, and when the business system is stopped or restarted, the sequence number is cached and cleared.

[0093] In this embodiment, by determining that the sequence number with the sequence number status of unavailable is not required to be recycled, unnecessary sequence number recycling and processing operations are avoided, the burden of sequence number recycling on the sequence number client can be reduced, and the performance of the sequence number client is optimized. In addition, by clearing the cache of sequence numbers that have been used in the business system, the same sequence number is prevented from being reused, thereby avoiding sequence number conflicts and data duplication, ensuring the uniqueness and consistency of each sequence number, and further ensuring the integrity of the business transaction data.

[0094] In an exemplary embodiment, Figure 4 As shown, after step 204, the method further includes steps 402 to 404. Among them:

[0095] Step 402: When the sequence number client meets the sequence number acquisition condition, it sends a sequence number acquisition request to the sequence number server.

[0096] The serial number acquisition request carries a service identifier and serial number requirement information, and the serial number requirement information includes the number of serial numbers requested by the service system.

[0097] The sequence number acquisition condition includes that the sequence number client receives a sequence number acquisition request, or the number of cached sequence numbers in the sequence number client is lower than a preset threshold, or the business system corresponding to the sequence number client is before a preset high concurrency period.

[0098] In the embodiment of the present application, when the sequence number acquisition condition is that the sequence number client receives the sequence number acquisition request, it means that the sequence number client deployed in the business system receives the sequence number acquisition request of the business system, then the sequence number client responds to the sequence number acquisition request, determines the cached sequence number in the sequence number client cache, and if the cached sequence number does not meet the sequence number requirement information, the sequence number client also sends a sequence number acquisition request to the sequence number server. Different business systems are used to process different businesses, and the sequence number client determines the business identifier and sequence number requirement information according to the business corresponding to the business system.

[0099] When the sequence number acquisition condition is that the number of cached sequence numbers in the sequence number client is lower than a preset threshold, the sequence number client can send a sequence number acquisition request to the sequence number server in advance based on the number of cached sequence numbers. Specifically, when the number of cached sequence numbers meets the preset threshold, the sequence number client triggers an instruction to send a sequence number acquisition request to the sequence number server. For example, when the number of cached sequence numbers is lower than the preset threshold, it means that the number of cached sequence numbers in the sequence number client may be lower than the number of sequence numbers that the business system acquires next time based on business needs. Therefore, when the number of cached sequence numbers is lower than the preset threshold, the sequence number client triggers a request to obtain the sequence number from the sequence number server, so as to improve the timeliness of the sequence number client's feedback of the sequence number to the business system and improve the performance of the sequence number server's feedback of the sequence number.

[0100] When the sequence number acquisition condition is that the business system corresponding to the sequence number client is before the preset high-concurrency period, the business system is about to face a high number of concurrent business transactions, and the sequence number client needs to obtain the sequence number from the sequence number server in advance to avoid the situation where the business system is unable to support business transactions during the high-concurrency period due to insufficient cached sequence numbers of the sequence number client. For example, when the business system is an e-commerce platform, the preset high-concurrency period may be before a shopping festival, or when the business system is a ticket purchase system, the preset high-concurrency period is before the ticket release period before the holiday. The sequence number client needs to obtain the sequence number from the sequence number server in advance, and the sequence number client sends a sequence number acquisition request to the sequence number server to avoid the situation where the sequence number client has insufficient cached sequence numbers.

[0101] Step 404: Receive a target sequence number set that meets the service identifier and sequence number requirement information and is sent from the recovery buffer pool by the sequence number service end.

[0102] In the embodiment of the present application, after the sequence number client sends a sequence number acquisition request to the sequence number server, the sequence number client will enter a waiting state to receive a response from the sequence number server. After the sequence number server receives the sequence number acquisition request from the sequence number client, it identifies the source of the sequence number acquisition request according to the business identifier to ensure that the correct sequence number is provided to the business system, and then generates a new target sequence number set from the recycling buffer pool according to the sequence number requirement information, and feeds the target sequence number set back to the sequence number client. The sequence number client receives a response from the sequence number server in the waiting state, and the client parses the response content, extracts and obtains the target sequence number set.

[0103] In this embodiment, a sequence number acquisition request is sent to the sequence number server according to the service identifier and sequence number requirement information, ensuring that the obtained sequence number set meets the service requirements, ensuring that the service system can proceed smoothly and maintain data consistency and reliability.

[0104] In an exemplary embodiment, Figure 5 As shown, a serial number recovery method is provided, which is applied to Figure 1 The serial number server in is taken as an example to illustrate, including the following steps 502 to 506. Among them:

[0105] Step 502: Receive the sequence number to be recycled sent by the sequence number client.

[0106] In the embodiment of the present application, if the business system needs to perform operation and maintenance operations (including stopping or restarting the business system), or if the business system is interrupted due to the interruption of the application of the sequence number, the sequence number client sends the sequence number to be recovered to the sequence number server through the sequence number recovery interface. The sequence number server communicates with the sequence number client in real time, and receives the sequence number to be recovered sent from the sequence number client in real time, wherein the sequence number server marks the sequence number to be recovered according to the business processed by the business system corresponding to the sequence number client, and records the business system corresponding to the sequence number to be recovered.

[0107] Step 504: store the sequence numbers to be recycled in the recycling buffer pool, and update the sequence numbers to be recycled to recycled sequence numbers. In response to the sequence number acquisition request sent by the sequence number client, build a target sequence number set based on the recycled sequence numbers.

[0108] In the embodiment of the present application, the sequence number server includes a recycling buffer pool, which is a buffer space opened in the sequence number server for storing the sequence number to be recycled. After the sequence number server successfully receives the sequence number to be recycled, the sequence number to be recycled is stored in the recycling buffer pool and updated to a recycled sequence number. The recycled sequence numbers stored in the recycling buffer pool are all sequence numbers that have not been used in the sequence number client.

[0109] Step 506: Return the target sequence number set to the sequence number client.

[0110] In an embodiment of the present application, when a business transaction of a business system requires the use of serial numbers when generating orders, etc., the serial number server responds to the serial number acquisition request of the serial number client, and preferentially obtains the number of recycled serial numbers required by the serial number client in the recycling buffer pool, builds a target serial number set based on the recycled serial numbers and feeds it back to the serial number client, thereby realizing the reuse of serial numbers.

[0111] In this embodiment, the serial number server automatically receives the serial numbers to be recycled sent by the serial number client, automatically stores the serial numbers to be recycled in the recycling resource pool, and automatically obtains the recycled serial numbers in the recycling resource pool for feedback when the serial number client issues a serial number acquisition request, which can improve the efficiency of serial number recovery and issuance.

[0112] In an exemplary embodiment, Figure 6 As shown, step 504 includes steps 602 to 608. Among them:

[0113] Step 602: Receive a sequence number acquisition request sent by a sequence number client.

[0114] The sequence number acquisition request carries a service identifier and sequence number requirement information, and the sequence number requirement information includes the first sequence number quantity.

[0115] In an embodiment of the present application, after receiving the sequence number acquisition request, the sequence number server parses the sequence number acquisition request, determines the service identifier and sequence number requirement information carried in the sequence number acquisition request, determines the recycled sequence number adapted to the sequence number acquisition request in the recycling cache pool according to the service identifier, and obtains the corresponding number of recycled sequence numbers according to the first sequence number quantity in the sequence number requirement information.

[0116] Step 604: If the first number of sequence numbers is less than or equal to the second number of sequence numbers of the recycled sequence numbers in the recycling buffer pool, based on the first number of sequence numbers, the recycled sequence numbers of the first number are obtained from the recycled sequence numbers containing the service identifier in the recycling buffer pool, and the recycled sequence numbers are determined as the target sequence number set.

[0117] In the embodiment of the present application, the sequence number server completes the parsing of the sequence number acquisition request and obtains that if the number of first sequence numbers in the sequence number acquisition request issued by the sequence number client is less than or equal to the number of second sequence numbers of recycled sequence numbers in the recycling buffer pool, it means that the number of recycled sequence numbers in the current recycling buffer pool can meet the number requirement of the sequence number client to obtain the sequence number this time, and then the sequence number server can construct the target sequence number set with only the recycled sequence numbers in the recycling buffer pool.

[0118] Step 606, if the first number of sequence numbers is greater than the second number of sequence numbers, based on the difference between the first number of sequence numbers and the second number of sequence numbers, obtain the target recycled sequence number from the recycled sequence numbers containing the service identifier in the recycling buffer pool, and generate the original sequence number in the sequence number resource pool.

[0119] In an embodiment of the present application, if the first number of sequence numbers corresponding to the number of sequence numbers required by the sequence number client is greater than the second number of sequence numbers stored in the recovery buffer pool, indicating that the recycled sequence numbers in the current recovery buffer pool cannot meet the number of sequence numbers required by the sequence number client for this time, the sequence number server not only uses all the recycled sequence numbers in the recycled sequence numbers containing the service identifier in the recovery buffer pool as the target recycled sequence numbers, but also generates an original sequence number in the sequence number resource pool based on the difference between the first number of sequence numbers and the second number of sequence numbers. The original sequence number is used as a supplement to the recycled sequence number to meet the number of sequence numbers required by the sequence number client for this time.

[0120] Step 608: construct a target sequence number set based on the target recovered sequence numbers and the original sequence numbers.

[0121] In an embodiment of the present application, the serial number server obtains the full amount of recycled serial numbers as target recycled serial numbers and combines them with the original serial numbers to construct a target sequence number set, and then feeds the target sequence number set back to the serial number client, thereby realizing the reuse of recycled serial numbers and meeting the serial number acquisition requirements of the business system.

[0122] In this embodiment, by parsing the sequence number acquisition request and checking the recycled sequence numbers in the recycling buffer pool, the sequence number server can quickly confirm the available sequence numbers of the business system according to the business identifier. If the recycled sequence numbers in the recycling buffer pool are sufficient, the sequence number server will directly meet the sequence number quantity requirement of the sequence number acquisition request; if the recycled sequence numbers do not meet the sequence number quantity requirement of the sequence number acquisition request, the sequence number server will generate the original sequence number as a supplement, thereby ensuring that the sequence number quantity requirement is met, and the recycled sequence number resources can be effectively reused, and the resource utilization efficiency is improved.

[0123] In an exemplary embodiment, a serial number recovery system is provided, the system comprising:

[0124] The sequence number client is used to determine the sequence number to be recycled from the cached sequence numbers based on the sequence number identifier if it is monitored that the operation status of the business system meets the preset operation status condition; the sequence number identifier indicates that the sequence number is not used; the sequence number to be recycled is sent to the sequence number server; the sequence number to be recycled is used to store in the sequence number server recovery cache pool for repeated use of sequence number resources;

[0125] The sequence number server is used to store the sequence numbers to be recycled in the recycling buffer pool of the sequence number server for reusing the sequence number resources.
