Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram of a main flow of an inventory deduction method according to a first embodiment of the present application, and as shown in fig. 1, the inventory deduction method includes:
and step S101, receiving the inventory deduction request, and carrying out local inventory deduction based on the inventory deduction request.
In this embodiment, an execution subject (for example, a server) of the inventory deduction method may receive the inventory deduction request through a wired connection or a wireless connection. In particular, the executive agent, upon receiving the inventory deduction request, may invoke a load balancing service to distribute the inventory deduction request to available inventory storage containers to cause the inventory storage solvent to perform local inventory deduction based on the inventory deduction request. The local inventory deduction is not an actual inventory deduction, but may be a reduction of the virtual number of the inventory made when the local inventory is sufficient compared to the inventory to be reduced for the inventory reduction request, or may indicate that the deduction was successful without making a reduction of the virtual number of the inventory when the local inventory is sufficient compared to the inventory to be reduced for the inventory reduction request.
Specifically, the local inventory deduction based on the inventory deduction request comprises the following steps:
the execution main body determines the inventory deduction amount corresponding to the inventory deduction request; comparing the inventory deduction amount with the local inventory of the inventory storage container distributed by the load balancing service, determining that the local inventory deduction amount is successful in response to the fact that the inventory deduction amount is smaller than the local inventory, further triggering a unified inventory deduction process, and determining that the local inventory deduction amount is failed in response to the fact that the inventory deduction amount is larger than the local inventory.
Specifically, the local inventory deduction based on the inventory deduction request comprises the following steps:
and in response to determining that the inventory storage container corresponding to the local inventory is down, calling the inventory storage container which normally works to perform local inventory pre-deduction. When the execution main body determines that the inventory storage container corresponding to the local inventory is down, the storage container which normally works can be detected, and the inventory deduction request is sent to the inventory storage container which normally works so as to carry out pre-deduction of the local inventory of the inventory storage container which normally works.
In this embodiment, specifically, the inventory deduction method further includes:
and traversing the rest inventory storage containers to execute corresponding local inventory deduction based on the inventory deduction request in response to determining that the local inventory deduction fails, and returning inventory deduction failure information in response to determining that the local inventory deduction corresponding to all the inventory storage containers fails and does not perform unified inventory deduction any more.
Specifically, when the executive agent determines that the local inventory deduction fails, indicating that the local inventory may not be deducted enough, the executive agent may send an inventory deduction request to other inventory storage containers, i.e., traverse the remaining inventory storage containers, so that the traversal of the arriving inventory storage containers continues the local inventory deduction based on the inventory deduction request until the local inventory deduction succeeds. If the local inventory corresponding to each inventory storage container fails to be deducted after traversing the rest inventory storage containers, the fact that the local inventory of all the inventory storage containers is not deducted sufficiently is indicated, and a sold-out prompt message can be directly returned. Unified inventory pre-deduction is not performed any more, so that unified cache pressure is relieved to a certain extent, and the phenomenon that a huge inventory deduction request amount collapses a unified cache is avoided.
And step S102, in response to the fact that the local inventory deduction is determined to be successful, unified inventory deduction is conducted based on the inventory deduction request.
And when the execution main body determines that the local inventory pre-deduction is successful, triggering a unified inventory pre-deduction process, and further performing unified inventory pre-deduction based on the inventory deduction request. Comparing the inventory deduction amount corresponding to the inventory deduction request with the unified inventory, and when the inventory deduction amount corresponding to the inventory deduction request is smaller than the unified inventory, indicating that the unified inventory deduction is successful; and when the inventory deduction amount corresponding to the inventory deduction request is larger than the unified inventory, indicating that the unified inventory deduction fails.
And step S103, in response to the fact that the unified inventory pre-deduction is successful, deduction of the local inventory and the unified inventory is carried out based on the inventory deduction request, and the order placing success information of the user is returned.
And step S104, in response to the fact that the unified inventory pre-deduction fails, rejecting deduction requests of the local inventory and the unified inventory, and returning inventory deduction failure information.
In the embodiment of the application, the unified inventory is a total inventory amount used for avoiding the over-selling condition.
If the executive determines that the local inventory pre-reduction is successful but the consolidated inventory pre-reduction fails, it indicates that the total inventory remaining (i.e., consolidated inventory) is not enough to be reduced, and if the actual reduction of the local inventory is still performed when the consolidated inventory pre-reduction fails, an over-selling condition of the item may result. Therefore, in response to determining that the unified inventory pre-deduction fails, the executive body rejects the deduction request of the local inventory and the unified inventory, and does not actually deduct the local inventory and the unified inventory, so as to avoid the over-selling condition caused by actual delivery. And if the execution main body determines that the local inventory pre-deduction is successful and the unified inventory pre-deduction is successful, the execution main body indicates that the current remaining total inventory is enough to carry out inventory deduction corresponding to the inventory deduction request, actual deduction of the local inventory and the unified inventory is carried out based on the inventory deduction request, the order placing success information of the user is returned, and then the subsequent goods delivery process is carried out.
The embodiment performs local inventory deduction based on the inventory deduction request by receiving the inventory deduction request; in response to determining that the local inventory deduction is successful, performing unified inventory deduction based on the inventory deduction request; and in response to determining that the unified inventory pre-deduction fails, rejecting a deduction request for the local inventory and the unified inventory, and returning inventory deduction failure information, or in response to determining that the unified inventory pre-deduction succeeds, carrying out deduction on the local inventory and the unified inventory based on the inventory deduction request, and returning order placing success information of a user. And the local deduction and the unified inventory deduction are combined, so that the performance pressure of the unified inventory deduction is relieved.
Fig. 2 is a schematic main flow chart of an inventory deduction method according to a second embodiment of the present application, and as shown in fig. 2, the inventory deduction method includes:
step S201, determining unified inventory, downtime and quantity of inventory storage containers.
Specifically, the stock is unified, for example, 100. The downtime, i.e., the chance of a failure of an inventory storage container, is, for example, 10%. The delay probability is not counted and limited, and can be determined according to actual conditions. The number of inventory storage containers may be, for example, the number of machines that store the inventory, and may be the number of servers that store the inventory, for example, 5.
Step S202, determining local inventory according to the unified inventory, the downtime and the quantity of the inventory storage containers.
The executing agent, after determining the unified inventory, the downtime, and the number of inventory storage containers, may perform an allocation of the local inventory of each inventory storage container. In an example, a certain inventory is evenly distributed to each inventory storage container, meanwhile, a certain reserved cache inventory quota is added for each inventory storage container on the basis of the average inventory quota, and local memory storage is adopted, so that local inventory is obtained. Therefore, when the inventory storage containers are delayed, because each inventory storage container has the reserved cache allowance, the inventory allowance on the delayed inventory storage container can still be reduced on other inventory storage containers, and the condition of selling lots of inventory storage containers is ensured.
Specifically, determining local inventory includes:
an average inventory is determined based on the unified inventory and the number of inventory storage containers.
Specifically, first, the execution principal may determine an average inventory according to the unified inventory and the number of inventory storage containers, and specifically, may determine a ratio of the unified inventory to the number of inventory storage containers as the average inventory.
And determining the cache allowance according to the average inventory, the downtime rate and the quantity of the inventory storage containers.
Specifically, the cache margin is the average inventory/[ (1-downtime) × number of inventory storage containers ], where "/" means "divided by". For example, the downtime rate is expected to be 10%, the total inventory is 100 for 5 switchboard machines, the average inventory is 10, and the cache margin is 10/(0.9 × 5) 20/9, and the cache margin setting principle may be: if the amount of cache is less than 1, and the downtime inventory is distributed to other machines as much as possible, the cache margin may be set to 3. The cache margin setting principle is not specifically limited in the embodiment of the application, and the setting can be performed based on the actual situation.
And determining the local inventory according to the average inventory and the inventory allowance.
Local inventory is average inventory + cache margin.
According to the method and the device, the cache allowance is reserved for the local inventory of each inventory storage container, so that when the inventory storage container is shut down, the inventory on the shut-down inventory storage container can still be deducted from other inventory storage containers which work normally, the condition that the articles are not sold less is ensured, and the controllability of the sales volume of the articles is ensured.
The inventory deduction method further comprises the following steps:
the local inventory is stored in the form of atomic variables for ongoing inventory deduction. The local inventory can be stored by adopting atomic variables, and the problem of multithread concurrency does not exist.
The inventory deduction method further comprises the following steps:
and storing the unified inventory in a queue form to obtain a unified inventory queue so as to deduct the unified inventory based on the unified inventory queue. And if the local inventory deduction is successful, requesting the remote unified inventory to carry out deduction, storing the remote unified inventory in a queue form by adopting redis cache, and realizing the deduction of the inventory by adopting pop-up operation of an inventory queue, thereby ensuring the atomicity and the performance.
And step S203, receiving the inventory deduction request, and performing local inventory deduction based on the inventory deduction request.
And step S204, responding to the fact that the local inventory deduction is successful, and conducting unified inventory deduction based on the inventory deduction request.
Step S205, in response to the fact that the unified inventory pre-deduction is successful, deduction of the local inventory and the unified inventory is carried out based on the inventory deduction request, and the information of successful ordering of the user is returned;
and step S206, in response to determining that the unified inventory pre-deduction fails, rejecting a deduction request for the local inventory and the unified inventory, and returning inventory deduction failure information.
The principle of step S203 to step S205 is similar to that of step S101 to step S103, and is not described here again.
According to the embodiment of the application, the local inventory deduction is firstly carried out once, when the local inventory is insufficient, the system directly returns that the user is sold out, the unified inventory deduction is not carried out any more, the unified cache pressure is relieved to a certain extent, and the condition that a large network request amount spans the redis cache is avoided. The reserved buffer inventory and the unified inventory deduction are combined, so that the condition of under-selling and over-selling due to the reserved buffer are avoided. On the basis of average inventory, reserving buffer inventory for each inventory storage container to avoid the condition of low sales; and a redis queue is adopted to realize the deduction of unified inventory amount, so that the over-selling condition is avoided. Local deduction and unified inventory deduction are combined, and unified inventory deduction performance pressure is relieved.
Fig. 3 is a schematic view of an application scenario of the inventory deduction method according to the third embodiment of the present application. The inventory deduction method can be applied to the multi-level deduction scene of the inventory of the articles. As shown in fig. 3, the server 302 receives the inventory deduction request 301, and performs local pre-deduction of the local inventory (e.g., local inventory 1, local inventory 2, local inventory 3) based on the inventory deduction request 301. The server 302 performs a consolidated pre-deduction of the consolidated inventory 303 based on the inventory deduction request 301 in response to determining that the local pre-deduction of the local inventory (which may be, for example, any one or more of local inventory 1, local inventory 2, local inventory 3) is successful. The server 302, in response to determining that the consolidated pre-deduction of the consolidated inventory 303 is successful, performs deduction of the local inventory (which may be any one or more of local inventory 1, local inventory 2, and local inventory 3, for example) and the consolidated inventory 303 based on the inventory deduction request 301, and returns a user ordering success information. The server 302, in response to determining that the unified pre-deduction of the unified inventory 303 fails, rejects the deduction requests for the local inventory (which may be any one or more of the local inventory 1, the local inventory 2, the local inventory 3, for example) and the unified inventory 303, returning inventory deduction failure information. There may be a plurality of local inventories, for example, there may be n local inventories, and the specific value of n is not limited in the embodiment of the present application.
According to the embodiment of the application, the local inventory deduction is firstly carried out once, when the local inventory is insufficient, the system directly returns that the user is sold out, the unified inventory deduction is not carried out any more, the unified cache pressure is relieved to a certain extent, and the condition that a large network request amount spans the redis cache is avoided. The reserved buffer inventory and the unified inventory deduction are combined, so that the condition of under-selling and over-selling due to the reserved buffer are avoided.
