Description

Technical Field

[0001] This application relates to the field of computer technology, specifically to a coupon inventory management method, a coupon inventory management device, a machine-readable storage medium, a computer program product, and a processor. Background Technology

[0002] With rapid economic development, businesses hold various activities to attract customers. Among these, electronic coupons are an important means for businesses to attract customers and increase customer retention. By providing coupons to customers, they can use them to offset part of the cash cost in transactions, thereby attracting customers to spend.

[0003] Existing methods for managing coupons fall into two categories: one is based on defining an inventory table in a database to store inventory information. This requires querying the database table each time to retrieve current inventory data and updating the inventory quantity promptly. However, in a clustered environment, frequent concurrent database access leads to low efficiency in retrieving inventory data. The other method is based on a custom Java cache for inventory information, which can improve efficiency. However, in a clustered environment, inventory information is inconsistent across different service nodes, making unified inventory management impossible. Furthermore, the custom Java cache is limited by system hardware (memory), which is unfavorable for large-scale events or multiple events.

[0004] Therefore, existing coupon management methods suffer from problems such as frequent database access, inability to uniformly manage inventory information, and are not conducive to the implementation of large-scale events and multiple events. Summary of the Invention

[0005] The purpose of this application is to provide a coupon inventory management method, a coupon inventory management device, a machine-readable storage medium, a computer program product, and a processor. This coupon inventory management method, by retrieving coupon information from Redis, significantly reduces reliance on database queries in a clustered concurrent mode, thus improving coupon retrieval efficiency. It avoids the problem of inconsistent inventory information obtained by different service nodes, facilitating unified inventory management and benefiting large-scale events and multiple events.

[0006] To achieve the above objectives, the first aspect of this application provides a coupon inventory management method, comprising:

[0010] The multiple coupon information items are stored in the database, and the predetermined number of coupon information items are cached in the Redis.

[0011] When claiming coupons, obtain coupon claiming activity information, and based on the coupon claiming activity information, obtain the coupon information to be claimed from the coupon information in Redis, and update the coupon information and activity inventory information in Redis.

[0012] In this embodiment of the application, obtaining the coupon information to be claimed from the coupon information in Redis based on the coupon activity information includes:

[0013] Based on the coupon redemption activity information, the current activity inventory information is retrieved from the Redis database.

[0014] Determine whether the current activity inventory information is greater than 0;

[0015] If the current activity inventory information is greater than 0, the coupon information to be claimed is obtained from the coupon information in Redis based on the coupon claiming activity information;

[0016] If the current active inventory information is not greater than 0, a prompt message will be generated.

[0017] In this embodiment of the application, the coupon inventory management method further includes:

[0018] Based on the coupon redemption activity information, the current coupon quantity information can be retrieved from the Redis;

[0019] Determine whether the current number of coupons is less than a preset warning value;

[0020] If the current number of coupons is less than a preset warning value, new coupon information is selected from the database and cached in Redis to update the coupon information in Redis.

[0021] In this embodiment of the application, when the current coupon quantity information is less than a preset warning value, the method further includes:

[0022] Based on the new activity, a new batch of coupon information is generated and stored in the database.

[0023] A second aspect of this application provides a coupon inventory management device, the coupon inventory management device comprising:

[0024] The inventory generation module is used to respond to an activity creation request, create a new activity, and generate the corresponding activity inventory information;

[0025] An inventory storage module is used to store the active inventory information in a database and Redis, respectively;

[0026] The coupon generation module is used to generate multiple coupon information based on the new activity, and select a predetermined number of coupon information from the multiple coupon information;

[0027] The coupon storage module is used to store the multiple coupon information into the database and cache the predetermined number of coupon information into the Redis;

[0028] The coupon management module is used to obtain coupon activity information when claiming coupons, and to retrieve coupon information to be claimed from the coupon information in Redis based on the coupon activity information, while updating the coupon information and activity inventory information in Redis.

[0029] In this embodiment of the application, the coupon management module includes:

[0030] The first query unit is used to query the current activity inventory information in Redis based on the coupon activity information;

[0031] The first judgment unit is used to determine whether the current active inventory information is greater than 0;

[0032] The claiming unit is used to obtain the coupon information to be claimed from the coupon information in Redis based on the coupon claiming activity information when the current activity inventory information is greater than 0.

[0033] The prompting unit is used to generate a prompt message when the current active inventory information is not greater than 0.

[0034] In this embodiment of the application, the coupon inventory management device further includes:

[0035] The coupon query module is used to query the current number of coupons in Redis based on the coupon redemption activity information;

[0036] The judgment module is used to determine whether the current coupon quantity information is less than a preset warning value;

[0037] The coupon update module is used to select new coupon information from the database and cache the new coupon information in Redis when the current number of coupons is less than a preset warning value, so as to update the coupon information in Redis.

[0038] A third aspect of this application provides a processor configured to perform the aforementioned coupon inventory management method.

[0039] A fourth aspect of this application provides a machine-readable storage medium storing instructions that, when executed by a processor, configure the processor to perform the aforementioned coupon inventory management method.

[0040] The fifth aspect of this application provides a computer program product, including a computer program that, when executed by a processor, implements the aforementioned coupon inventory management method.

[0041] The above technical solution involves creating a new activity and generating corresponding activity inventory information; storing this inventory information in both a database and Redis; generating multiple coupon information entries based on the new activity, and selecting a predetermined number of coupon entries from these entries; storing these coupon entries in the database and caching the predetermined number of coupon entries in Redis; and retrieving coupons by obtaining coupon activity information and retrieving coupons from Redis based on this information, while simultaneously updating the coupon information and activity inventory information in Redis. When a coupon activity is created, activity inventory information and coupon information are generated. The initial activity inventory information and coupon information are recorded in the database, while Redis caches and stores the activity inventory information and a portion of the coupon information. Retrieving coupon information from Redis significantly reduces the reliance on database queries in a clustered concurrent mode, improving coupon retrieval efficiency. By using a database and Redis to record the initial activity inventory information and coupon information, the problem of inconsistent inventory information obtained by different service nodes can be avoided, facilitating unified inventory management. This is beneficial for large-scale activities and multiple activities, and also avoids the problem of inventory data loss due to service restarts.

[0055] The coupon inventory management method provided in this application can be applied to, for example... Figure 1 The application environment shown is illustrated. Terminal 102 communicates with server 104 via a network. A coupon inventory management method is provided. When a coupon activity is created, activity inventory information and coupon information are generated. The initial activity inventory information and coupon information are recorded in a database, and the activity inventory information and partial coupon information are cached in Redis. Coupon information is retrieved from Redis, significantly reducing the reliance on database queries in a clustered concurrent mode and improving coupon retrieval efficiency. This avoids the problem of inconsistent inventory information obtained by different service nodes, facilitating unified inventory information management, which is beneficial for large-scale activities and multiple activities. It also avoids the problem of inventory data loss due to service restarts. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. Server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0056] Figure 2 A schematic flowchart illustrating a coupon inventory management method according to an embodiment of this application is shown. Figure 2 As shown, in one embodiment of this application, a coupon inventory management method is provided. This embodiment mainly applies this method to the above-mentioned... Figure 1 Taking terminal 102 (or server 104) as an example, the following steps are included:

[0057] Step 210: In response to the activity creation request, create a new activity and generate the corresponding activity inventory information;

[0058] In this embodiment, the coupon inventory management method can be executed by an inventory management service. The aforementioned "create activity request" refers to creating a coupon activity. After receiving the user's request to create a coupon activity, the inventory management service creates a new activity. The new activity includes information such as the coupon activity's identity document (ID), the coupon activity's address, and the coupon activity's inventory, thereby generating activity inventory information. Activity inventory information refers to the remaining quantity of coupons to be distributed in this activity.

[0059] Step 220: Store the activity inventory information in the database and Redis respectively;

[0060] In this embodiment, the activity inventory information is stored in both the database and Redis. During storage, "KC" (inventory) plus the ID of the coupon activity can be used as the primary key, and the inventory quantity of the coupon activity can be used as the value, cached in Redis in a key-value pair manner.

[0061] The database can be an enterprise-grade distributed database (Tencent Distributed Database, TDSQL). TDSQL is Tencent Cloud's enterprise-grade distributed database, encompassing a complete database product system with multiple engines including financial-grade distributed, cloud-native, and analytical databases. It provides industry-leading capabilities such as financial-grade high availability, compute-storage separation, data warehousing, and enterprise-grade security, while also offering a comprehensive product service system including an intelligent operation and maintenance platform and a serverless version. The Remote Dictionary Server (Redis) is an open-source, ANSI C-written, network-enabled, in-memory or persistent log-structured key-value database with a read speed of 110,000 times / s and a write speed of 81,000 times / s. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperlog, geospatial indexes, and streams. Redis features built-in replication, Lua scripting, LRU eviction, transactions, and different levels of disk persistence, and provides high availability through Redis Sentinel and Redis Cluster automatic partitioning.

[0062] Step 230: Based on the new activity, generate multiple coupon information and select a predetermined number of coupon information from the multiple coupon information;

[0063] Step 240: Store the multiple coupon information in the database, and cache the predetermined number of coupon information in the Redis;

[0064] In this embodiment, after storing the activity inventory information, the inventory management server begins generating a batch of coupon information. Since generating coupon information is time-consuming, it can be done in batches. For example, 10,000 coupons can be generated initially, then 5,000 coupons can be selected and stored in Redis, while the remaining 10,000 coupons can be stored in the database. Similar to the method of storing activity inventory information, "YHQ" (coupon) plus the activity ID can be used as the key, and the coupon information as the value, cached in Redis in a key-value manner.

[0065] Step 250: When claiming coupons, obtain coupon claiming activity information, and based on the coupon claiming activity information, obtain the coupon information to be claimed from the coupon information in Redis, and update the coupon information and activity inventory information in Redis.

[0066] In this embodiment, since Redis caches the activity inventory information and the predetermined number of coupons, participants can retrieve coupons from Redis without accessing the database. The coupon activity information includes the activity ID and the number of coupons to be claimed. For example, when claiming a coupon for the first time, a coupon can be retrieved from Redis based on the activity ID, and the coupon information can be returned. Simultaneously, the activity inventory information is decremented by 1, and the corresponding coupon information is deleted from Redis.

[0067] In the above implementation process, a new activity is created, and corresponding activity inventory information is generated. This activity inventory information is stored in both a database and Redis. Based on the new activity, multiple coupon information items are generated, and a predetermined number of coupons are selected from these items. These coupons are stored in the database, and the predetermined number of coupons are cached in Redis. When claiming coupons, coupon claiming activity information is obtained, and based on this information, the coupons to be claimed are retrieved from the coupon information in Redis. Simultaneously, the coupon information and activity inventory information in Redis are updated. When a coupon activity is created, activity inventory information and coupon information are generated. The initial activity inventory information and coupon information are recorded in the database, while Redis caches and stores the activity inventory information and a portion of the coupon information. Claiming coupon information from Redis significantly reduces the reliance on database queries in a clustered concurrent mode, improving coupon claiming efficiency. By using a database and Redis to record the initial activity inventory information and coupon information, the problem of inconsistent inventory information obtained by different service nodes can be avoided, facilitating unified inventory management. This is beneficial for large-scale activities and multiple activities, and also avoids the problem of inventory data loss due to service restarts.

[0068] In some embodiments, after multiple coupon redemptions, to ensure the availability of coupon information to be redeemed, the step of retrieving the coupon information from Redis based on the coupon redemption activity information includes the following steps:

[0069] First, based on the coupon redemption activity information, the current activity inventory information is retrieved from the Redis database;

[0070] Then, determine whether the current active inventory information is greater than 0;

[0071] Then, if the current activity inventory information is greater than 0, the coupon information to be claimed is obtained from the coupon information in Redis based on the coupon claiming activity information;

[0072] Finally, if the current active inventory information is not greater than 0, a prompt message is generated.

[0073] In this embodiment, after multiple coupon claims, when an activity participant claims another coupon, the inventory management service can query the current inventory information in Redis based on "KC" + activity ID. If the current inventory information is greater than 0, a coupon is retrieved from the coupon information based on "YHQ" + activity ID and returned. At the same time, the coupon is deleted from Redis, and the activity inventory information is decremented by 1.

[0074] By checking if the current activity inventory is greater than 0, it determines whether there are still coupons available. Coupons are only claimed if the current inventory is greater than 0, ensuring that users can access available coupons. If the current inventory is 0, it means there are no coupons remaining, and an insufficient inventory alert is generated and returned to notify the user that the claim has failed. This allows users to stay informed about the activity's inventory status.

[0075] In some embodiments, after multiple coupon redemptions, to ensure that the number of coupons cached in Redis meets the redemption demand, the coupon inventory management method further includes the following steps:

[0076] First, based on the coupon redemption activity information, the current number of coupons is retrieved from the Redis database;

[0077] Then, it is determined whether the current coupon quantity information is less than a preset warning value;

[0078] Then, if the current number of coupons is less than a preset warning value, new coupon information is selected from the database and cached in Redis to update the coupon information in Redis.

[0079] In this embodiment, considering the large number of coupons required for large-scale events and the time-consuming nature of generating coupon information, it is advisable to generate coupon information in batches. Specifically, the number of coupons generated in step 230 is less than the number of coupons generated in step 210. For example, if the event inventory is 20,000, the number of coupons generated is 10,000. The preset warning value can be pre-set according to actual needs. When the number of coupons cached in Redis is less than the warning value, the inventory management service retrieves new coupon information from the database and stores it in Redis; when the number of coupons cached in Redis is not less than the warning value, no operation is performed. For example, initially, 10,000 coupons are generated, then 5,000 are synchronized to Redis. A warning value of 1,000 is set; when the number of coupons in Redis falls below 1,000, another 5,000 coupons are synchronized from the database to Redis.

[0080] It should be noted that the above steps can be performed before, after, or at other times, obtaining the coupon information to be claimed from the coupon information in Redis. This embodiment does not limit the specific timeframe.

[0081] By determining whether the current number of coupons is less than a preset warning value, the system can promptly understand the number of coupons in Redis. If the current number of coupons is less than the preset warning value, new coupon information is selected from the database and cached in Redis to update the coupon information in Redis. This ensures that coupon information can be replenished in a timely manner when the current number of coupons is lower than the preset warning value, thus ensuring that the number of coupons cached in Redis meets the redemption requirements.

[0082] In some embodiments, when generating coupon information in batches, if the current number of coupons is less than a preset warning value, the method further includes: generating a new batch of coupon information according to the new activity, and storing the new batch of coupon information in the database.

[0083] In this embodiment, when the number of coupons cached in Redis is less than the warning value, the inventory management service retrieves new coupon information from the database and stores it in Redis. At the same time, it starts generating the next batch of coupon information and saves it to the database to wait for the next time to be cached in Redis.

[0084] Generating coupon information is a time-consuming and resource-intensive task. By pre-generating a portion of coupon information and then requesting the next batch from the inventory management server when the number of coupons in Redis falls below a preset warning threshold, multiple campaigns can be launched within a shorter timeframe. This avoids situations where prolonged campaign durations, large coupon generation, and prolonged resource consumption can negatively impact other campaigns. By asynchronously and in batches generating coupon information, the system bottleneck issue of being unable to support large-scale campaigns or multiple campaigns running simultaneously is resolved.

[0085] The following example illustrates the solution; please refer to it. Figure 3 , Figure 3 The illustration shows a schematic diagram of the coupon redemption process according to an embodiment of this application.

[0086] When a user sends a request to create an activity, the inventory management service creates the new activity, generates activity inventory information, and saves this information to TDSQL and caches it in Redis. Then, it generates coupon information based on the activity, saves it to TDSQL, and stores a portion of the coupon information in Redis. Upon first claiming a coupon, the inventory management service retrieves a coupon from Redis based on the activity ID, returns the coupon information, and decrements the inventory by 1. After participating in the activity multiple times following these steps, upon claiming a coupon again, the inventory management service retrieves a coupon from Redis based on the activity ID. It then checks if the number of coupons in Redis has reached a warning threshold. If so, Redis returns the coupon information, decrements the inventory by 1, sends a warning message, and retrieves the next batch of coupon information from TDSQL and caches it in Redis. If not, Redis returns the coupon information, decrements the inventory by 1, and the coupon claim is successful. Upon receiving the warning message, the inventory management service generates a new batch of coupons and saves them to TDSQL.
