[0039] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0040] It should be noted that the collection, collection, updating, analysis, processing, use, transmission, storage and other aspects of user personal information involved in the technical solution of the present invention are in compliance with the provisions of relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. Necessary measures are taken for user personal information to prevent illegal access to user personal information data and maintain the security of user personal information, network security and national security.

[0041] Figure 1 1 is a schematic diagram of main steps of a method for reducing inventory of items according to an embodiment of the present invention.

[0042] like Figure 1 As shown, the inventory deduction method of an item according to an embodiment of the present invention mainly includes the following steps S101 to S104.

[0043] Step S101: in response to an inventory deduction request for an item, obtain an inventory deduction value of the item to be deducted and at least one inventory slice corresponding to the item to be deducted.

[0044] Specifically, the items to be deducted can be best-selling items or promotional items for promotional activities. Each item to be deducted has a pre-set number of inventory shards, each inventory shard can include a preset number of inventory subdomains, each inventory shard includes an activated inventory subdomain, and can also include an inventory subdomain to be activated, a locked inventory subdomain, etc., and each inventory subdomain has a pre-occupied inventory value. Among them, the inventory shard (Partition) can be constructed based on the redis (a high-performance database) storage unit. In an inventory shard, a certain amount of pre-occupied inventory will be stored. When a service is requested to deduct inventory, only one of the inventory shards needs to be selected, which can reduce the pressure on a single node. At the same time, based on the scalability of the redis cluster, the horizontal expansion of the inventory shard can be achieved. A certain amount of pre-occupied inventory value will be stored in each inventory subdomain included in the inventory shard, and the pre-occupied inventory value is not very large, which can ensure the dynamic pre-occupied inventory implementation, thereby solving the problem of inventory tilt.

[0045] Figure 2 Schematic diagram of an inventory deduction method for items according to an embodiment of the present invention.

[0046] like Figure 2 As shown, the items to be deducted have four corresponding inventory slices, namely inventory slice A, inventory slice B, inventory slice C and inventory slice D. Taking inventory slice A as an example, inventory slice A includes inventory subdomain A1 and inventory subdomain A2. The pre-occupied inventory value of inventory subdomain A1 is 100, and the pre-occupied inventory value of inventory subdomain A2 is 80. The activated inventory subdomain in inventory slice A is inventory subdomain A2, and the inventory subdomain to be activated in inventory slice A is inventory subdomain A1.

[0047] Step S102: According to the preset inventory slice determination rule and the inventory deduction value, a target inventory slice corresponding to the item to be deducted is selected from the inventory slices.

[0048] In one embodiment, according to a preset inventory shard determination rule, based on the inventory deduction value, selecting a target inventory shard corresponding to the item to be deducted from the inventory shards may include: based on the pre-occupied inventory value of the activated inventory subdomain of each inventory shard, selecting a target inventory shard corresponding to the item to be deducted from the inventory shards whose pre-occupied inventory value reaches the inventory deduction value.

[0049] Specifically, the inventory deduction value of the item to be deducted is, for example, 75. Figure 2 , the pre-occupied inventory value of the activated inventory subdomain of inventory shard A is 80, the pre-occupied inventory value of the activated inventory subdomain of inventory shard B is 70, the pre-occupied inventory value of the activated inventory subdomain of inventory shard C is 60, and the pre-occupied inventory value of the activated inventory subdomain of inventory shard D is 50. Then the inventory shard scheduler determines that the inventory shard that meets the inventory deduction value of the item to be deducted is inventory shard A, and inventory shard A can be selected as the target inventory shard corresponding to the item to be deducted. It should be noted that if there are multiple inventory shards that meet the inventory deduction value of the item to be deducted, the inventory shard corresponding to the pre-occupied inventory value of the largest activated inventory subdomain can be selected as the target inventory shard.

[0050] Step S103: According to the inventory deduction value, the inventory of the items to be deducted is deducted through the activated inventory subdomain in the target inventory slice, and the inventory deduction information is generated.

[0051] In one embodiment, inventory deduction of items to be deducted is performed according to the inventory deduction value through the activated inventory subdomain in the target inventory shard, which may include: calculating the occupied inventory value after deduction according to the occupied inventory value and the inventory deduction value of the activated inventory subdomain in the target inventory shard; and updating the occupied inventory value of the activated inventory subdomain in the target inventory shard using the occupied inventory value after deduction.

[0052] Specifically, the inventory deduction value of the item to be deducted is, for example, 75, the target inventory slice is inventory slice A, the activated inventory subdomain is inventory subdomain A2, and the reserved inventory value of inventory subdomain A2 is 80. Then, the reserved inventory value after deduction is 5, that is, the difference between 80 and 75. After the inventory deduction, the reserved inventory value of inventory subdomain A2 is updated to 5.

[0053] In one embodiment, after the occupied inventory value of the activated inventory subdomain in the target inventory shard is updated using the deducted occupied inventory value, the method may further include: comparing the deducted occupied inventory value with a preset first occupied inventory threshold; if the deducted occupied inventory value does not reach the first occupied inventory threshold, setting the activated inventory subdomain to a locked inventory subdomain, and determining a new activated inventory subdomain of the target inventory shard from the inventory subdomains to be activated included in the target inventory shard.

[0054] Specifically, the pre-occupied inventory value after deduction is 5, and the preset pre-occupied inventory first threshold is set to 10, for example. Then the pre-occupied inventory value after deduction does not reach the pre-occupied inventory first threshold, and at this time, the inventory subdomain A2 needs to be set as the locked inventory subdomain. The inventory subdomain to be activated included in the inventory shard A is the inventory subdomain A1, and the inventory subdomain A1 is set as the new activated inventory subdomain.

[0055] In one embodiment, after the activated inventory subdomain is set as the locked inventory subdomain, the method may further include: calculating the to-be-replenished pre-occupied inventory value of the locked inventory subdomain according to a preset second threshold of the pre-occupied inventory and the pre-occupied inventory value after deduction, obtaining the pre-occupied inventory value to be replenished from the preset inventory pool and replenishing it into the locked inventory subdomain, and setting the locked inventory subdomain as the to-be-activated inventory subdomain.

[0056] Specifically, the preset second threshold of pre-occupied inventory is set to 100, for example, the locked inventory subdomain is inventory subdomain A2, the pre-occupied inventory value after deduction of inventory subdomain A2 is 5, and the pre-occupied inventory value to be replenished in inventory subdomain A2 is 95, that is, the difference between 100 and 5. Through the pre-occupied inventory task trigger, 95 of pre-occupied inventory is obtained from the preset inventory pool and replenished into inventory subdomain A2, and inventory subdomain A2 is set as the inventory subdomain to be activated.

[0057] In one embodiment, before obtaining the pre-occupied inventory of the pre-occupied inventory value to be replenished from the preset inventory pool, the method may further include: determining whether there is pre-occupied inventory of the pre-occupied inventory value to be replenished in the preset inventory pool, and determining whether there is pre-occupied inventory of the pre-occupied inventory value to be replenished in the preset inventory pool. If there is no pre-occupied inventory of the pre-occupied inventory value to be replenished in the preset inventory pool, inventory replenishment is not performed on the locked inventory subdomain.

[0058] In one embodiment, when all the inventory subdomains included in the target inventory shard are locked inventory subdomains, the number of inventory shards corresponding to the items to be deducted can be determined; when the number of inventory shards is greater than 1, the occupied inventory values ​​of all inventory subdomains included in the target inventory shard can be added to the preset inventory pool, and the target inventory shard can be deleted.

[0059] Specifically, if all the inventory subdomains included in the target inventory shard are locked inventory subdomains, it means that the inventory in the preset inventory pool is about to be exhausted and the locked inventory subdomains cannot be replenished. At this time, if the inventory shard corresponding to the item to be deducted is greater than 1, the reserved inventory values ​​of all inventory subdomains included in the target inventory shard can be added to the preset inventory pool, and the target inventory shard can be deleted.

[0060] In one embodiment, when the number of inventory shards is less than or equal to 1, all the inventory in the preset inventory pool can be added to the locked inventory subdomain of the target inventory shard, and the locked inventory subdomains can be set as activated inventory subdomains one by one to perform inventory deductions for the items to be deducted through the activated inventory subdomains; in response to the pre-occupied inventory value of each inventory subdomain included in the target inventory shard being 0, the target inventory shard is deleted.

[0061] Specifically, when all the inventory subdomains included in the target inventory shard are locked inventory subdomains, if the inventory shard corresponding to the item to be deducted is less than or equal to 1, it means that the target inventory shard is the only inventory shard corresponding to the item to be deducted, and all the inventory in the preset inventory pool can be added to the locked inventory subdomain of the target inventory shard, and the inventory deduction is performed through the inventory subdomains in the target inventory shard until the reserved inventory value of each inventory subdomain included in the target inventory shard is 0, indicating that the inventory in the preset inventory pool is exhausted, and the target inventory shard is deleted.

[0062] Step S104: In response to satisfying the inventory deduction synchronization rule, deduct the item inventory from the inventory detail table according to the inventory deduction information. The inventory deduction synchronization rule may include: the current time reaches a preset inventory synchronization time (such as 1 second), or the number of current inventory deduction information reaches a preset information number threshold.

[0063] Specifically, in response to satisfying the inventory deduction synchronization rule, an inventory deduction message is generated through the recorded inventory deduction information, and the inventory detail table is subjected to item inventory deduction and synchronization based on the inventory deduction message.

[0064] Figure 3 It is a flowchart of a method for reducing inventory of items according to an embodiment of the present invention.

[0065] like Figure 3As shown, in one embodiment, the inventory deduction value of the item to be deducted and the multiple inventory slices corresponding to the item to be deducted are obtained, and the target inventory slice corresponding to the item to be deducted is selected from the inventory slices according to the inventory deduction value, and the inventory of the item to be deducted is deducted through the activated inventory subdomain in the target inventory slice according to the inventory deduction value, and the inventory of the item is deducted from the inventory detail table according to the inventory deduction information. The pre-occupied inventory value after deduction is compared with the preset pre-occupied inventory first threshold value, and when the pre-occupied inventory value after deduction does not reach the pre-occupied inventory first threshold value, the activated inventory subdomain is set as the locked inventory subdomain, and a new activated inventory subdomain of the target inventory slice is determined from the to-be-activated inventory subdomain included in the target inventory slice, and then the pre-occupied inventory is obtained from the preset inventory pool and added to the locked inventory subdomain, and the locked inventory subdomain is set as the to-be-activated inventory subdomain.

[0066] The embodiment of the present invention builds a distributed framework for inventory deductions based on the distributed management of the cache layer. At the same time, in order to avoid the data skew problem caused by access, the scalability of inventory deductions is achieved by setting inventory shards including multiple inventory subdomains for the deducted items, thereby improving the efficiency of inventory deductions and being able to cope with inventory deduction operations in high-concurrency scenarios.
