[0029] Example 1

[0030] Figure 1 This is a flowchart of a serial number allocation method according to Embodiment 1 of this application. This embodiment is applicable to efficient serial number processing based on pre-allocation of number segments in the financial field. It can be executed by a serial number allocation device, which can be implemented in hardware and / or software and can be configured in a computer device, such as a server. Figure 1 As shown, the method includes:

[0031] S110. In response to the serial number acquisition request from the requesting end, apply for a number segment from the pre-configured serial number database according to the serial number acquisition request, and store the acquired number segment in the main number segment cache area.

[0032] The request for a serial number can originate from different services needing a serial number. The requesting service can include various internal bank services, such as account management, transaction processing, and loan approval services. The pre-configured serial number database is a pre-set database used to store and manage serial numbers, ensuring the uniqueness and continuity of each serial number. The main serial number segment cache stores the currently used serial number segments; when the requesting service needs a serial number, it will be allocated from this cache.

[0033] Optionally, there are at least two requesting ends. Correspondingly, based on the sequence number retrieval request, a number segment is requested from a pre-configured sequence number database, including: performing conflict verification on the number segments requested in the sequence number retrieval requests of the at least two requesting ends, and obtaining a conflict verification result; based on the conflict verification result, determining the duplicated number segments and the at least two requesting ends corresponding to the duplicated number segments; determining the currently allocable requesting ends and the pending requesting ends based on the priority of the sequence number retrieval requests of the at least two requesting ends corresponding to the duplicated number segments; for the currently allocable requesting ends, requesting a number segment from the pre-configured sequence number database based on the sequence number retrieval request of the currently allocable requesting ends; for the pending requesting ends, using an exponential backoff algorithm for intelligent retries, and rejecting the sequence number retrieval request of the pending requesting ends if the number of retries exceeds a preset number of retries.

[0034] The conflict verification process verifies sequence number retrieval requests from multiple requesting clients to check for duplicate number ranges and avoid conflicts. The priority of sequence number retrieval requests can be set based on the importance of the business, etc., and this embodiment does not impose specific limitations. The exponential backoff algorithm is a dynamically adjusted retry interval algorithm, where the retry interval increases exponentially with each retry. The preset number of retries can be set according to actual needs, and this embodiment does not impose specific limitations on this. When the number of retries exceeds the preset number, the system stops attempting retries and directly rejects the sequence number retrieval request. By gradually increasing the retry interval, the load on the server is reduced, and the probability of success is increased.

[0035] Specifically, conflict checking is performed on requests from at least two requesters to determine if duplicate number segments exist, thus avoiding duplicate allocation of sequence numbers. If conflict checking reveals duplicate number segments, it identifies which segments were requested repeatedly and the corresponding requesting clients. Then, based on request priority, it determines which requests can be processed immediately and which need to wait. For higher-priority requesting clients, number segments are immediately requested from the sequence number database to fulfill their requests; for lower-priority requesting clients or those requiring waiting, an exponential backoff algorithm is used for retries. If the request is unsuccessful after a preset number of retries, it is rejected to avoid resource waste and system overload.

[0036] S120. If the main number segment cache area meets the cache area replacement conditions based on the serial number consumption rate of the main number segment cache area, the backup number segment cache area is started asynchronously.

[0037] The serial number consumption rate is used to characterize the usage of serial numbers in the current number segment cache, dynamically managing and optimizing the serial number allocation process to ensure system efficiency and stability. The serial number consumption rate can be calculated as the ratio of the number of allocated serial numbers to the total number of serial numbers. For example, if the current number segment cache has 100 serial numbers and 80 have been allocated, the consumption rate is 80%. A high consumption rate means that the serial numbers in the current number segment cache are about to be exhausted, while a low consumption rate indicates that there are still many serial numbers available for allocation. For example, when the serial number consumption rate reaches a preset prefetch threshold (e.g., 50%), a cache replacement operation can be triggered to ensure a continuous supply of serial numbers. The backup number segment cache is used to store pre-loaded serial number segments, ready to take over when the main number segment cache is exhausted. By monitoring and analyzing the serial number consumption rate, resource allocation can be dynamically adjusted to ensure a continuous supply of serial numbers, while also promptly detecting and handling abnormal situations.

[0038] S130. If the serial number usage in the primary number segment cache area is determined to meet the switching conditions, then the backup number segment cache area is switched to the primary number segment cache area.

[0039] The serial number usage in the primary number segment cache can include the serial number consumption rate, the number of allocated serial numbers, the number of remaining serial numbers, the request frequency, and the system load. When the serial number usage meets the switching conditions, the backup number segment cache is switched to the primary number segment cache. For example, the switch can be triggered when the serial number consumption rate in the primary number segment cache exceeds a preset threshold; it can also be triggered when the frequency of requesting serial numbers exceeds a preset threshold; or it can be triggered when the system load (such as CPU utilization, memory utilization, etc.) exceeds a preset threshold. The preset threshold can be set according to actual needs, and this embodiment does not specifically limit it.

[0040] Optionally, the step of switching the backup number segment cache to the main number segment cache if the serial number usage in the main number segment cache meets the switching conditions includes: determining the remaining number of serial numbers in the main number segment cache based on the serial number usage in the main number segment cache; determining that the serial number usage meets the switching conditions when the remaining number of serial numbers is less than a preset number threshold; and switching the backup number segment cache to the main number segment cache when the serial number usage meets the switching conditions.

[0041] Specifically, the system monitors the serial number usage in the primary number segment cache area, calculates the remaining number of serial numbers (the number of unallocated serial numbers in the primary number segment cache area), and compares this remaining number with a preset threshold. If the remaining number is less than the preset threshold, the switching condition is met, and the backup number segment cache area is switched to the primary number segment cache area to continue allocating serial numbers. This ensures the efficiency and reliability of serial number allocation when processing a large number of transactions and account numbers. The preset threshold can be set according to actual needs; this embodiment does not impose specific limitations on it.

[0042] S140. Using an atomic increment operation, a sequence number is allocated to the requesting end in the main number segment cache.

[0043] Atomic increment operations are a type of operation that maintains consistency in multithreaded or distributed environments. An atomic operation means that its execution will not be interrupted by other operations, thus guaranteeing the integrity and correctness of the operation. In a multithreaded environment, multiple threads may simultaneously request sequence number allocation. Atomic increment operations ensure that each allocated sequence number is unique, preventing duplicates or conflicts. Using atomic increment operations to allocate sequence numbers ensures that each allocated sequence number is unique and will not conflict with other operations.

[0044] This application responds to the requesting client's serial number retrieval request, requests a number segment from a pre-configured serial number database based on the serial number retrieval request, and stores the requested number segment in the main number segment cache area. If the main number segment cache area meets the cache area replacement conditions based on the serial number consumption rate of the main number segment cache area, a backup number segment cache area is asynchronously started. If the serial number usage in the main number segment cache area meets the switching conditions based on the serial number usage of the main number segment cache area, the backup number segment cache area is switched to the main number segment cache area. An atomic increment operation is used to allocate a serial number to the requesting client in the main number segment cache area. The above solution reduces frequent access to the serial number database and improves system response speed through a caching mechanism; it improves the continuity and availability of serial number allocation by asynchronously preloading new number segments and switching the cache to allocate serial numbers to the requesting end; atomic increment operations ensure the accuracy of serial number allocation and avoid duplication or omission; through real-time monitoring and asynchronous operations, the serial number cache can be dynamically expanded according to actual needs, ensuring service continuity and stability; asynchronously starting the backup number segment cache can reduce latency when the cache is exhausted, improving user experience while efficiently managing serial number allocation in high-concurrency environments.

[0045] Example 2

[0046] Figure 2This is a flowchart of a serial number allocation method according to Embodiment 2 of this application. Based on the technical solutions of the above embodiments, this embodiment refines the statement "if the main number segment cache area meets the cache area replacement condition based on the serial number consumption rate of the main number segment cache area, then asynchronously start the backup number segment cache area" to "real-time monitoring of the serial number consumption rate of the main number segment cache area; if the serial number consumption rate is greater than a preset prefetch threshold, determining that the main number segment cache area meets the cache area replacement condition; if the main number segment cache area meets the cache area replacement condition, asynchronously starting the backup number segment cache area, applying for a new number segment from the pre-configured serial number database, and performing overlap verification on the new number segment to obtain a verification result; if the verification result is successful, storing the new number segment in the backup number segment cache area; if the verification result is unsuccessful, reapplying for a new number segment from the serial number database until the verification result is successful." It should be noted that for parts not detailed in this embodiment, please refer to the relevant descriptions in other embodiments. Figure 2 As shown, the method includes:

[0047] S210. In response to the serial number acquisition request from the requesting end, apply for a number segment from the pre-configured serial number database according to the serial number acquisition request, and store the acquired number segment in the main number segment cache area.

[0048] S220. Real-time monitoring of the serial number consumption rate of the main number segment cache area. If the serial number consumption rate is greater than the preset prefetch threshold, it is determined that the main number segment cache area meets the cache area replacement conditions.

[0049] Specifically, the serial number consumption rate of the main number segment cache is continuously monitored to ensure timely detection of changes in the consumption rate. When the serial number consumption rate of the main number segment cache exceeds a preset prefetch threshold, it is determined that the main number segment cache meets the replacement conditions and a cache switch is required. For example, each transaction requires a unique transaction number. By monitoring the serial number consumption rate of the main number segment cache in real time, the cache is switched promptly when the consumption rate exceeds the preset prefetch threshold to prevent transaction number exhaustion. When issuing instruments (such as checks, drafts, etc.), the serial number consumption rate of the main number segment cache is monitored in real time to ensure timely switching of the cache when the consumption rate exceeds the preset prefetch threshold to prevent instrument number exhaustion. The preset prefetch threshold can be set according to actual needs; for example, the preset prefetch threshold can be 50%, but this embodiment does not specifically limit it. Through a database prefetching mechanism, request blocking when a number segment is exhausted is eliminated. When the current number segment in memory is consumed to 50% (customizable), a new number segment is asynchronously preloaded to ensure continuous availability of serial number allocation.

[0050] S230. If the main number segment cache area meets the cache area replacement conditions, the backup number segment cache area is started asynchronously, a new number segment is applied for from the pre-configured serial number database, and the new number segment is subjected to overlap verification to obtain the verification result.

[0051] The overlap check is used to check whether the newly applied number segment overlaps with the already allocated number segment, ensuring the uniqueness of the new number segment. The check result can include failure and success.

[0052] Optionally, an overlap check is performed on the new number segment to obtain a check result, including: obtaining the start and end serial numbers of the new number segment; querying the currently allocated serial number range; comparing the new number segment with the allocated serial number range to determine whether there is overlap; if the new number segment overlaps with the allocated serial number range, the check result is determined to be a failure; if the new number segment does not overlap with the allocated serial number range, the check result is determined to be a pass.

[0053] The new number segment's start and end sequence numbers are the initial and final sequence numbers of the newly applied number segment, used to identify the range of that segment. The allocated sequence number range is the currently allocated sequence number range, stored in the sequence number database to record the allocated number segments. The new number segment is compared with the allocated sequence number ranges to determine if there is overlap. If overlap exists, the verification result is determined to be a failure; if no overlap exists, the verification result is determined to be a success, ensuring the uniqueness of the new number segment.

[0054] S240. If the verification result is successful, the new number segment is stored in the backup number segment cache area.

[0055] S250. If the verification result is a failure, a new number segment is applied for again from the serial number database until the verification result is a success.

[0056] Specifically, in the event of a verification failure, a new number segment is requested from the sequence number database, and an overlap verification is performed until a new number segment that does not overlap with the already allocated number segment is found, at which point the verification result is considered successful. Each time a verification fails, detailed information about the failure is recorded, including the range of the new number segment, the reason for the failure, and the timestamp. This detailed information is stored in a pre-configured log database for subsequent analysis and auditing. Combined with real-time monitoring logs, this enables visualized tracking of the number segment lifecycle, second-level alerts for abnormal allocation patterns, and improved resource utilization.

[0057] S260. If the serial number usage in the primary number segment cache area is determined to meet the switching conditions, then the backup number segment cache area is switched to the primary number segment cache area.

[0058] S270. Using an atomic increment operation, a sequence number is allocated to the requesting end in the main number segment cache.

[0059] In one optional implementation, the system further includes notifying the caller to execute a custom degradation strategy when a system-level anomaly is detected; wherein the system-level anomaly includes configuration anomaly, database consistency anomaly, resource exhaustion anomaly, and service availability anomaly; the custom degradation strategy includes using an alternative sequence number generation algorithm or service, limiting the rate of business processing, and returning error information.

[0060] System-level anomalies indicate a serious problem or an unrecoverable abnormal state. Upper-layer applications should implement circuit breaker mechanisms (e.g., application termination). These anomalies require intervention from system administrators or developers to conduct detailed log analysis and system checks to determine the root cause and implement appropriate remedial measures. Specifically, configuration anomalies are caused by internal system configuration errors, such as incorrect or missing parameters in configuration files, leading to system malfunction. Database consistency anomalies involve database state issues, such as illegal values ​​in configuration tables or unexplained consistency problems in the database. These issues typically require database administrator intervention. Resource exhaustion anomalies occur when all pre-allocated sequence numbers are exhausted, and the system configuration does not allow for sequence number recycling, indicating that a critical system resource has been depleted. Service availability anomalies indicate that a service or component has failed to initialize or cannot complete initialization for some reason, thus failing to provide service. This could be due to dependent service failures, network problems, or other errors during startup.

[0061] The caller can be the client that initiates the serial number retrieval request. A custom degradation strategy is a backup strategy that the caller can execute when the request cannot be fulfilled, ensuring that some functions remain available. Using a backup serial number generation algorithm or service means that the system predefines one or more backup serial number generation mechanisms. When the primary serial number generation service becomes unavailable due to a failure, it automatically switches to these backup mechanisms to continue generating serial numbers. For example, the backup serial number generation algorithm could be retrieving serial numbers from another database, or generating serial numbers using an algorithm based on timestamps and machine identifiers; the backup service could be another independent serial number generation service instance, which can be deployed on different servers or data centers to improve availability and fault tolerance, reducing business interruptions caused by primary service failures. A circuit breaker mechanism is established, allowing the caller to customize a degradation strategy when serial number generation is abnormal, ensuring that serial number generation in core business processes is not affected.

[0062] In one optional implementation, the method further includes employing an exponential backoff algorithm for intelligent retries when a retryable exception is detected, and rejecting the sequence number acquisition request from the requesting end if the number of retries exceeds a preset number of retries; wherein the retryable exception includes database operation exception, retry policy exception, operation timeout exception, and retryable interruption exception.

[0063] Retryable exceptions typically indicate exceptions caused by unexpected or unpredictable temporary unavailability of external systems, which are expected to recover on their own. Specifically, database operation exceptions usually occur when database operations (such as queries, updates, and inserts) fail, possibly due to network problems, temporary database service unavailability, or timeouts. Retry policy exceptions are thrown when the internal retries reach or exceed the limit set by the configuration class. This indicates that multiple attempts have been made without success, and the upper-layer application needs to decide whether to continue retrying. Operation timeout exceptions occur when a system operation fails to complete within a predetermined time; for example, a request does not receive a response within a specified timeout period. Retryable interruption exceptions occur when a thread is interrupted while performing a retry operation, but this interruption is recoverable, and retrying can continue after the interruption is handled. Exception handling and retry strategies can improve system robustness and user experience.

[0064] This application responds to the requesting client's serial number retrieval request, requests a number segment from a pre-configured serial number database based on the serial number retrieval request, and stores the requested number segment in the main number segment cache area. If the main number segment cache area meets the cache area replacement conditions based on the serial number consumption rate of the main number segment cache area, a backup number segment cache area is asynchronously started. If the serial number usage in the main number segment cache area meets the switching conditions based on the serial number usage of the main number segment cache area, the backup number segment cache area is switched to the main number segment cache area. An atomic increment operation is used to allocate a serial number to the requesting client in the main number segment cache area. The above solution reduces frequent access to the serial number database and improves system response speed through a caching mechanism; it improves the continuity and availability of serial number allocation by asynchronously preloading new number segments and switching the cache to allocate serial numbers to the requesting end; atomic increment operations ensure the accuracy of serial number allocation and avoid duplication or omission; through real-time monitoring and asynchronous operations, the serial number cache can be dynamically expanded according to actual needs, ensuring service continuity and stability; asynchronously starting the backup number segment cache can reduce latency when the cache is exhausted, improving user experience while efficiently managing serial number allocation in high-concurrency environments.
