[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 sequence numbers corresponding to messages and data.

[0003] In traditional technology, when a serial number needs to be recycled during business use, the developer identifies the serial numbers no longer in use in the business system in the serial number client, updates the recycled status of the serial numbers in the serial number server's database, and marks the serial numbers to be recycled as recycled in the database. Furthermore, when the serial number client obtains a new serial number, it checks this status flag and returns the recycled serial number to the serial number client first, avoiding the reallocation of used serial numbers.

[0067] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this 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 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 operating status of the business system meets the preset operating status conditions, it determines the sequence number to be recycled in the cached sequence numbers 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 reuse of sequence number resources. Among them, the sequence number client 102 can be deployed in the business system. When each business system needs to obtain a sequence number or recycle a sequence number, it interacts with the sequence number server 104 through the sequence number client 102 on the business system to achieve sequence number acquisition or sequence number recycling. 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 the example is used 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] The serial number identifier indicates 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 running state of the business system in real time, and the serial number client is pre-configured with preset running state conditions, which include business system stop, business system restart, and business interruption, etc. Among them, the business system stop and the business system restart are the operation of stopping or restarting the business system by the operation and maintenance personnel in the scene of system upgrade or system repair of the business system. At this time, the business system receives the stop or restart instruction and prepares for stopping or restarting.

[0073] In 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 number provided by the serial number client for the business system is stored in the cache of the serial number client. Therefore, the serial number client needs to recycle the recycled serial numbers in the cache of the serial number client before the business system stops or restarts.

[0074] Firstly, in the process of continuously monitoring the business system in real time by the serial number client, if it is monitored that the running state of the business system is in the above-mentioned business system stop, business system restart or business interruption, the serial number client calls the serial number recycling interface, which includes the processing flow of recycling the serial number for the business system. The serial number stored in the cache of the serial number client 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 (a batch of serial number set corresponding to the number of business demand) into the cache. After some serial numbers in the serial number sequence are used, the business system feeds back the message that the serial number is used to the serial number client, and then the serial number client can modify the serial number identifier of the used serial number in the serial number sequence, i.e. from "serial number unused" to "serial number used". Therefore, the serial number client can determine the unused recycled serial number in the cached serial number based on the serial number identifier.

[0075] Step 204, sending the recycled serial number to the serial number server.

[0076] Among them, the recycled serial number is used to store in the recycling cache pool of the serial number server for the reuse of serial number resources.

[0077] In an embodiment of the present application, after a sequence number client identifies a sequence number to be recycled from cached sequence numbers based on a sequence number identifier, the client sends the sequence number to be recycled to a sequence number server via a sequence number recycling interface. The sequence number server includes a recycling buffer pool for storing the sequence numbers to be recycled. This storage of the sequence numbers to be recycled by the sequence number server allows for the reuse of sequence number resources. Furthermore, the recycling buffer pool on the sequence number server utilizes a caching mechanism to store the sequence numbers to be recycled in the cache. This improves the performance of business systems obtaining sequence numbers from the sequence number server via the client, compared to adjusting the sequence number status in the database.

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

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

[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 search the cached serial numbers in the cache for the serial number used for the interrupted business corresponding to the business interruption status, 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 serial numbers to be recycled when the business system is interrupted, unused serial numbers can be recycled more comprehensively, the utilization rate of serial number resources can be improved, and the interruption or skipping of serial 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 detected, the business operation interruption condition is that when the business transaction of the business system generates a transaction order based on the acquired serial number, the generation process of the transaction order is interrupted. 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. The serial number status of the serial number includes a serial number available state or a serial number unavailable state.

[0087] Step 304: If the feedback message from the business system is a sequence number application interruption message, the sequence number status is determined to be a sequence number available status, 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 one embodiment of the present application, in response to a sequence number status query request from a sequence number client, the business system queries the business transaction corresponding to the business operation interruption condition and determines the type of business operation interruption condition encountered in the business transaction. If the type of business operation interruption condition is a sequence number application interruption message, this indicates that before the sequence number was applied, a logical error occurred in the business system when generating the transaction order for the business transaction, resulting in a failure to generate the transaction order. This indicates that the sequence number used for the business operation interruption condition was not applied. The business system then sends back a 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. Furthermore, the sequence number client receives the feedback message from the business system. 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 business system can continue to use the sequence number corresponding to the sequence number application interruption message when conducting subsequent business transactions. Therefore, the sequence number client sends the sequence number corresponding to the sequence number application interruption message to the sequence number server via 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 serial 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.

[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 numbers in the sequence number unavailable state are cleared from the cache.

[0092] In an embodiment of the present application, if the type of the business operation interruption condition is a business interruption message, it indicates 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, in the business, the order is interrupted due to the user's cancellation of the order or payment, that is, the business interruption. At this time, since the business system has completed the order generation, 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 with the sequence number unavailable status. 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 thus ensuring the integrity of 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 satisfies 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 an embodiment of the present application, when the sequence number acquisition condition is that the sequence number client receives a sequence number acquisition request, it indicates that the sequence number client deployed in the business system has received the sequence number acquisition request from the business system. The sequence number client responds to the sequence number acquisition request and determines the cached sequence number in the sequence number client cache. 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 handle 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 will acquire 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 a preset high-concurrency period, the business system is about to face a high number of concurrent business transactions. 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 on 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 purchasing system, the preset high-concurrency period may be before the ticket release period before a 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 the target sequence number set that meets the service identifier and sequence number requirement information sent by the sequence number server from the recycling buffer pool.

[0102] In the embodiment of the present application, after the sequence number client sends the sequence number acquisition request to the sequence number server, the sequence number client enters a waiting state to receive the response from the sequence number server. After the sequence number server receives the sequence number acquisition request of the sequence number client, the sequence number server identifies the source of the sequence number acquisition request according to the business identifier, ensures to provide the correct sequence number for the business system, and then generates a new target sequence number set according to the sequence number requirement information from the recycling cache pool, and feeds back the target sequence number set to the sequence number client. The sequence number client receives the 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 the embodiment, the sequence number acquisition request is sent to the sequence number server according to the business identifier and the sequence number requirement information, so as to ensure that the obtained sequence number set meets the business demand, and ensure that the business system can proceed smoothly and maintain data consistency and reliability.

[0104] In an exemplary embodiment, as shown in Figure 5 , a sequence number recycling method is provided, which is applied to the sequence number server in Figure 1 for example, and includes the following steps 502 to 506. Among them:

[0105] Step 502, receiving the to-be-recycled sequence number sent by the sequence number client.

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

[0107] Step 504, storing the to-be-recycled sequence number into the recycling cache pool, updating the to-be-recycled sequence number into the recycled sequence number, and constructing a target sequence number set based on the recycled sequence number in response to the sequence number acquisition request sent by the sequence number client.

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

[0109] Step 506, returning 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 from 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 the 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 quantity of the first sequence numbers.

[0115] In an embodiment of the present application, after the serial number server receives the serial number acquisition request, it parses the serial number acquisition request, determines the service identifier and serial number requirement information carried in the serial number acquisition request, determines the recycled serial number that is compatible with the serial number acquisition request in the recycling cache pool based on the service identifier, and obtains the corresponding number of recycled serial numbers according to the first serial number quantity in the serial 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, obtain the first number of recycled sequence numbers from the recycled sequence numbers containing the service identifier in the recycling buffer pool, and determine the recycled sequence numbers as the target sequence number set.

[0117] In an 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 sequence numbers 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 recycling buffer pool, it means that the recycled sequence numbers in the current recycling buffer pool cannot meet the number of sequence numbers required by the sequence number client to obtain this time. Then the sequence number server not only uses all the recycled sequence numbers in the recycled sequence numbers containing the service identifier in the recycling 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 serves as a supplement to the recycled sequence number to meet the number of sequence numbers required by the sequence number client to obtain 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 serial number set, and then feeds the target serial 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, effectively reusing the recycled sequence number resources, and improving resource utilization efficiency.

[0123] In an exemplary embodiment, a serial number recycling 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 monitors that the business system operation status meets the preset operation status conditions; the sequence number identifier indicates that the sequence number is unused; send the sequence number to be recycled to the sequence number server; the sequence number to be recycled is used to store it in the sequence number server's recycling cache pool for reuse 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 reuse of the sequence number resources.
