The above embodiments of the present disclosure have the following advantages: by the inventory preemption method of some embodiments of the present disclosure, inventory preemption timeout times are reduced. Specifically, the reason why the number of times of the stock preemption timeout is large is that: when the number of orders is large, the stock preemption performance is degraded, resulting in a large number of times of stock preemption timeout. Based on this, the inventory preemption method of some embodiments of the present disclosure first performs preemption processing on the pre-emptible amount and the accumulated pre-emptive amount included in the inventory preemption information in response to determining that the inventory preemption information corresponding to the item information exists in the memory database for each item information in the item information set corresponding to the target order. Thus, it is possible to pre-camp on the stock by the pre-camp-on process of the stock pre-camp-on information in the stock database. Then, in response to determining that the pre-occupation processing of the pre-occupation amount included in the inventory pre-occupation information corresponding to each item information in the item information set is successful, inserting an inventory pre-occupation task corresponding to the target order into a first database, and adding the inventory pre-occupation task to a target inventory pre-occupation task queue, wherein the first database stores the inventory pre-occupation tasks corresponding to each order, and the target inventory pre-occupation task queue includes the inventory pre-occupation tasks corresponding to each order. Therefore, when the pre-occupation of each stock pre-occupation information corresponding to the target order in the stock database is successful, the stock pre-occupation task corresponding to the target order is added to the target stock pre-occupation task queue for unified scheduling. And then, in response to that the task state of the inventory preemption task corresponding to the target order in the target inventory preemption task queue is an execution state, updating the inventory information in the second database corresponding to each item information in the item information set. Thus, when the stock pre-occupation task corresponding to the target order in the target stock pre-occupation task queue is executed, the stock information corresponding to the target order in the second database can be updated, namely, the stock of each article corresponding to the target order is actually pre-occupied. And finally, in response to the fact that the updating processing of the inventory information in the second database is successful, according to the quantity of the articles included in the article information corresponding to the inventory information which is successfully updated, reducing the accumulated pre-occupied quantity included in the inventory pre-occupied information in the memory database corresponding to the inventory information which is successfully updated. Thus, after the inventory information corresponding to the target order in the second database is successfully updated, the accumulated pre-occupation amount corresponding to the inventory information in the second database can be dynamically updated. And the inventory information in the second database is not directly updated, but the inventory pre-occupation is performed through the memory database firstly, and then the unified scheduling is performed on each inventory pre-occupation task through the target inventory pre-occupation task queue so as to update the inventory information in the second database, so that the inventory pre-occupation performance is improved. Thus, inventory preemption timeout times are reduced.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
1-2 are schematic diagrams of one application scenario of an inventory preemption method according to some embodiments of the present disclosure.
In the application scenario of fig. 1, first, for each item information (e.g., item information 1021) in the item information set 102 corresponding to the target order, the computing device 101 may perform preemption processing on the amount 1031 and the cumulative amount 1032 that are included in the stock preemption information 103 in response to determining that the stock preemption information 103 corresponding to the item information 1021 exists in the in-memory database. Then, in response to determining that the pre-emptible amount pre-emption process included in the inventory pre-emptive information corresponding to each item information in the item information set 102 is successful, the computing device 101 may insert an inventory pre-emptive task 104 corresponding to the target order into the first database, and add the inventory pre-emptive task 104 to the target inventory pre-emptive task queue 105. The first database stores stock pre-occupation tasks corresponding to the orders. The target stock preemption task queue 105 includes stock preemption tasks corresponding to respective orders. Thereafter, the computing device 101 may update the inventory information (e.g., the inventory information 106) in the second database corresponding to each item information (e.g., the item information 1021) in the item information set 102 in response to the task status of the inventory preemption task 104 corresponding to the target order in the target inventory preemption task queue 105 being in an execution status. Finally, in response to determining that the update process of the inventory information (e.g., the inventory information 106) in the second database is successful, the computing device 101 may perform a deduction process on the accumulated pre-occupation amount 1032 included in the inventory pre-occupation information 103 in the memory database corresponding to the inventory information 106 that is successfully updated according to the amount of the item included in the item information (e.g., the item information 1021) corresponding to the inventory information (e.g., the inventory information 106) that is successfully updated.
Alternatively, as shown in fig. 2, in response to receiving the ex-warehouse information 107 of the target order, the computing device 101 may perform a deduction process on each actual stock amount 108 included in each stock information in the second database corresponding to each item information in the item information set 102.
The computing device 101 may be hardware or software. When the computing device is hardware, it may be implemented as a distributed cluster composed of multiple servers or terminal devices, or may be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices enumerated above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.
It should be understood that the number of computing devices in fig. 1-2 is merely illustrative. There may be any number of computing devices, as implementation needs dictate.
With continued reference to fig. 3, a flow 300 of some embodiments of an inventory preemption method in accordance with the present disclosure is illustrated. The inventory pre-occupation method comprises the following steps:
step 301, for each item information in the item information set corresponding to the target order, in response to determining that the inventory preemption information corresponding to the item information exists in the memory database, performing preemption processing on the pre-occupation amount and the accumulated pre-occupation amount included in the inventory preemption information.
In some embodiments, for each item information in the set of item information corresponding to the target order, an executing entity (e.g., computing device 101 shown in fig. 1) of the inventory preemption method can perform preemption processing on the preemptable amount and the accumulated preempted amount included in the inventory preemption information in response to determining that the inventory preemption information corresponding to the item information exists in the in-memory database. The target order may be an order currently received by the executing agent. The item information set may be item information of each item selected by the user corresponding to the target order when placing the order. The article information may be related information of the article. The above item information may include, but is not limited to: item number, item name, item quantity. The item number may be used to uniquely identify the item. The quantity of the items may be the quantity of the items determined by the user when placing an order. The memory database may be a database for pre-empting the stock in the memory. For example, the in-memory database may be a "Redis database". The stock preemption information may be stock preemption related information corresponding to an item in the memory database. The inventory preemption information may include, but is not limited to: item number, warehouse number, pre-occupied amount, cumulative pre-occupied amount. The above-mentioned warehouse number may be used to uniquely identify the warehouse. The pre-occupation amount can be the residual amount of the articles corresponding to the article numbers in the warehouse corresponding to the warehouse numbers. The accumulated amount of the pre-emption may be the number of the items in the warehouse in the pre-emption state. The above-described preemption processing may include a deduction processing for a preemptible amount and an accumulation processing for an accumulated preemption amount. In practice, first, the execution body may determine a difference between the pre-emptible quantity and the quantity of the article as the pre-emptible quantity to update the pre-emptible quantity. Then, the execution body may determine a sum of the cumulative preemption amount and the item amount as a cumulative preemption amount to update the cumulative preemption amount. Thus, it is possible to pre-camp on the stock by the pre-camp-on process of the stock pre-camp-on information in the stock database.
Step 302, in response to determining that the pre-occupation processing for the pre-occupation amount included in the inventory pre-occupation information corresponding to each item information in the item information set is successful, inserting an inventory pre-occupation task corresponding to the target order into the first database, and adding the inventory pre-occupation task to the target inventory pre-occupation task queue.
In some embodiments, the execution main body may insert an inventory preemption task corresponding to the target order in the first database in response to determining that the preemptible amount preemption processing included in the inventory preemption information corresponding to each item information in the item information set is successful, and add the inventory preemption task to the target inventory preemption task queue. The first database may be a database for storing an inventory preemption task. For example, the first database may be a "MYSQL database". The stock preemption task may be represented by stock preemption information with a task state added. The first database stores stock preemption tasks corresponding to respective orders. The target inventory preemption task queue may be a queue for adding an inventory preemption task corresponding to the target order. The target inventory preemption task queue includes inventory preemption tasks corresponding to each order. And the stock pre-occupation tasks of all orders in the target stock pre-occupation task queue are tasks to be executed. In practice, the execution subject may add the inventory preemption task to the tail of the target inventory preemption task queue. Therefore, when the pre-occupation of each stock pre-occupation information corresponding to the target order in the stock database is successful, the stock pre-occupation task corresponding to the target order is added to the target stock pre-occupation task queue for unified scheduling.
Step 303, in response to that the task state of the inventory preemption task corresponding to the target order in the target inventory preemption task queue is an execution state, updating the inventory information in the second database corresponding to each item information in the item information set.
In some embodiments, the executing agent may update the inventory information in the second database corresponding to each item information in the item information set in response to that the task state of the inventory preemption task corresponding to the target order in the target inventory preemption task queue is an execution state. The execution state may represent that the execution subject currently executes the inventory preemption task. The second database may be a database for actually pre-empting the inventory. For example, the second database may be a "MYSQL database". The inventory information may be inventory related information corresponding to an item in the second database. The inventory information may include, but is not limited to: article number, warehouse number, pre-occupiable volume. In practice, the execution main body may determine a difference between the amount of the product and the amount of the product included in the inventory information as a pre-emptible amount, so as to update the pre-emptible amount included in the inventory information. Thus, when the stock pre-occupation task corresponding to the target order in the target stock pre-occupation task queue is executed, the stock information corresponding to the target order in the second database can be updated, namely, the stock of each article corresponding to the target order is actually pre-occupied.
Step 304, in response to determining that the update processing of the inventory information in the second database is successful, according to the quantity of the items included in the item information corresponding to the inventory information that is successfully updated, performing deduction processing on the accumulated pre-occupation quantity included in the inventory pre-occupation information in the memory database corresponding to the inventory information that is successfully updated.
In some embodiments, the executing entity may perform, in response to determining that the update processing of the inventory information in the second database is successful, a deduction processing on an accumulated pre-occupation amount included in the inventory pre-occupation information in the memory database corresponding to the inventory information that is successfully updated according to an item amount included in the item information corresponding to the inventory information that is successfully updated. In practice, the execution subject may determine a difference between the accumulated occupancy amount and the item amount as an accumulated occupancy amount to reduce the accumulated occupancy amount included in the stock occupancy information. Thus, after the inventory information corresponding to the target order in the second database is successfully updated, the accumulated pre-occupation amount corresponding to the inventory information in the second database can be dynamically updated.
Optionally, the executing entity may perform, in response to receiving the shipment information of the target order, deduction processing on each actual stock amount included in each stock information in the second database corresponding to each item information in the item information set. The warehouse-out information may represent that each article corresponding to the target order has been warehouse-out. The inventory information in the above-mentioned respective inventory information may further include an actual inventory amount. The actual stock quantity may be the stock quantity of the article corresponding to the article number in the warehouse corresponding to the warehouse number included in the stock information. In practice, for each item information of the respective item information, the execution main body may determine a difference between an actual stock quantity corresponding to the item information and an item amount included in the item information as an actual stock quantity to reduce the actual stock quantity. Thus, the actual stock quantity of each item in the second database can be updated after each item corresponding to the target order is delivered.
Optionally, the executing body may add, in response to that an inventory preemption task whose task state is unexecuted exists in the first database within a target preset period, the inventory preemption task whose task state is unexecuted in the first database to the target inventory preemption task queue. The target preset cycle may be a current cycle period. In practice, the executing body may sequentially add each inventory preemption task whose task state is not executed to the tail of the target inventory preemption task queue. Thus, when the execution of the stock-keeping task fails, the stock-keeping task can be executed again.
Optionally, the executing body may perform rollback processing on each stock preemption information that the previous preemption processing succeeds, in response to determining that the stock preemption information preemption processing corresponding to the item information in the item information set fails. The rollback process may be a process of canceling a previously pre-reserved stock. In practice, the execution main body may determine that the preemption processing for the inventory preemption information is failed in response to determining that a difference between a preemptible amount included in the inventory preemption information and an amount of an item included in the item information corresponding to the inventory preemption information is less than zero. For each of the stock preemption information for which the preemption process is successful, the execution main body may determine a sum of a preemptible amount included in the stock preemption information and an amount of an item included in the item information corresponding to the stock preemption information as the preemptible amount of the stock preemption information to rollback the stock preemption information. Thus, when the stock preemption information corresponding to the item information in the item information set fails to preempt, the previously preempted stock can be cancelled.
Optionally, the execution main body may send preset prompting information to the terminal device corresponding to the target order in response to determining that the rollback processing of each stock preemption information that succeeds in the prior preemption processing is successful. Wherein, the preset prompt information represents that the inventory is insufficient. The preset prompting information may be preset information for prompting a user corresponding to the terminal device. For example, the preset prompting message may be "there is an article out of stock in your order". Thus, after the stock of the pre-occupied goods is withdrawn, the user can be prompted that the current stock is insufficient.
Alternatively, first, the execution main body may generate the adjustment amount based on the pre-occupation amount included in the stock preemption information that has failed in the preemption processing and the amount of the item included in the item information corresponding to the stock preemption information that has failed in the preemption processing, in response to determining that the rollback processing is successful for each stock preemption information that has succeeded in the preemption processing. In practice, the executing body may determine an absolute value of a difference between the pre-emptible quantity and the quantity of the article as the adjustment quantity. Then, the execution main body may transmit the scheduled amount to an associated display apparatus. The display device may be a device having a display function. The display device may be a display device on a warehouse side that stores the article corresponding to the stock preemption information. In practice, the execution main body may transmit the adjustment amount to the display device through a wired connection manner or a wireless connection manner. Thus, the amount of dispatch of the article for which the preemption process failed can be displayed.
Optionally, controlling the associated scheduling device to execute the item scheduling operation according to the scheduling amount. The scheduling device may be a device for scheduling an article. For example, the scheduling device may be an "unmanned vehicle". In practice, the executing body may control the dispatching device to dispatch the dispatched articles. The article is an article corresponding to the article information corresponding to the dispatch amount. Therefore, the scheduling equipment can be enabled to automatically schedule the articles according to the scheduling amount.
The above embodiments of the present disclosure have the following advantages: by the inventory preemption method of some embodiments of the present disclosure, inventory preemption timeout times are reduced. Specifically, the reason why the number of times of the stock preemption timeout is large is that: when the number of orders is large, the stock preemption performance is degraded, resulting in a large number of times of stock preemption timeout. Based on this, the inventory preemption method of some embodiments of the present disclosure first performs preemption processing on the pre-emptible amount and the accumulated pre-emptive amount included in the inventory preemption information in response to determining that the inventory preemption information corresponding to the item information exists in the memory database for each item information in the item information set corresponding to the target order. Thus, it is possible to pre-camp on the stock by the pre-camp-on process of the stock pre-camp-on information in the stock database. Then, in response to determining that the pre-occupation processing of the pre-occupation amount included in the inventory pre-occupation information corresponding to each item information in the item information set is successful, inserting an inventory pre-occupation task corresponding to the target order into a first database, and adding the inventory pre-occupation task to a target inventory pre-occupation task queue, wherein the first database stores the inventory pre-occupation tasks corresponding to each order, and the target inventory pre-occupation task queue includes the inventory pre-occupation tasks corresponding to each order. Therefore, when the pre-occupation of each stock pre-occupation information corresponding to the target order in the stock database is successful, the stock pre-occupation task corresponding to the target order is added to the target stock pre-occupation task queue for unified scheduling. And then, in response to that the task state of the inventory preemption task corresponding to the target order in the target inventory preemption task queue is an execution state, updating the inventory information in the second database corresponding to each item information in the item information set. Thus, when the stock pre-occupation task corresponding to the target order in the target stock pre-occupation task queue is executed, the stock information corresponding to the target order in the second database can be updated, namely, the stock of each article corresponding to the target order is actually pre-occupied. And finally, in response to the fact that the updating processing of the inventory information in the second database is successful, according to the quantity of the articles included in the article information corresponding to the inventory information which is successfully updated, reducing the accumulated pre-occupied quantity included in the inventory pre-occupied information in the memory database corresponding to the inventory information which is successfully updated. Thus, after the inventory information corresponding to the target order in the second database is successfully updated, the accumulated pre-occupation amount corresponding to the inventory information in the second database can be dynamically updated. And the inventory information in the second database is not directly updated, but the inventory pre-occupation is performed through the memory database firstly, and then the unified scheduling is performed on each inventory pre-occupation task through the target inventory pre-occupation task queue so as to update the inventory information in the second database, so that the inventory pre-occupation performance is improved. Thus, inventory preemption timeout times are reduced.
With further reference to FIG. 4, a flow 400 of further embodiments of an inventory preemption method is illustrated. The process 400 of the inventory preemption method includes the steps of:
step 401, for each item information in the item information set corresponding to the target order, in response to determining that the inventory preemption information corresponding to the item information exists in the memory database, performing preemption processing on the pre-occupation amount and the accumulated pre-occupation amount included in the inventory preemption information.
Step 402, in response to determining that the pre-occupation processing for the pre-occupation amount included in the inventory pre-occupation information corresponding to each item information in the item information set is successful, inserting an inventory pre-occupation task corresponding to the target order into the first database, and adding the inventory pre-occupation task to the target inventory pre-occupation task queue.
Step 403, in response to that the task state of the inventory preemption task corresponding to the target order in the target inventory preemption task queue is an execution state, updating the inventory information in the second database corresponding to each item information in the item information set.
Step 404, in response to determining that the update processing of the inventory information in the second database is successful, according to the quantity of the items included in the item information corresponding to the inventory information that is successfully updated, performing deduction processing on the accumulated pre-occupation quantity included in the inventory pre-occupation information in the memory database corresponding to the inventory information that is successfully updated.
In some embodiments, the specific implementation and technical effects of steps 401 and 404 can refer to steps 301 and 304 in those embodiments corresponding to fig. 3, which are not described herein again.
Step 405, in response to determining that the inventory preemption information corresponding to the item information does not exist in the memory database, acquiring inventory information corresponding to the item information from the second database as target inventory information.
In some embodiments, an executing entity (e.g., the computing device 101 shown in fig. 1) of the inventory preemption method may acquire inventory information corresponding to the item information from the second database as target inventory information in response to determining that the inventory preemption information corresponding to the item information does not exist in the in-memory database. In practice, the executing entity may obtain, from the second database, inventory information including an item code and a warehouse code that are respectively the same as the item code and the warehouse code included in the item information, as the target inventory information, through a wired connection manner or a wireless connection manner.
At step 406, inventory preemption information corresponding to the item information is created in an inventory database based on the amount of preemption included with the target inventory information.
In some embodiments, the execution agent may create inventory preemption information corresponding to the item information in the in-memory database based on a preemptible amount included in the target inventory information. In practice, the execution agent may newly establish an inventory preemption message in the in-memory database. The newly created stock pre-occupation information includes an article code identical to the article code included in the article information, a warehouse code of a warehouse storing the article corresponding to the article information, a pre-occupation amount included in the target stock information, and an accumulated pre-occupation amount with an initial value of zero. Thus, when the stock preemption information corresponding to the article information does not exist in the stock database, the stock database can be initialized.
Step 407, in response to that the first and second pre-emptible amounts satisfy the first predetermined difference condition, or that each of the first pre-emptible amounts in the memory database and each of the second pre-emptible amounts in the second database satisfy the second predetermined difference condition, determining the inventory preemption information corresponding to the first pre-emptible amount as the expired inventory preemption information.
In some embodiments, the execution agent may determine, as the expired inventory preemption information, inventory preemption information corresponding to the first preemptable amount in response to the first and second preemptable amounts satisfying a first predetermined difference condition, or each of the first preemptable amounts in the in-memory database and each of the second preemptable amounts in the second database satisfying a second predetermined difference condition. The first preemptible amount may be a preemptible amount included in the inventory preemption information in the memory database. The second preemptible amount may be a preemptible amount included in the inventory information corresponding to the inventory preemption information in the second database. The expired inventory preemption information described above is not available for preemption processing. The above-described first predetermined difference condition may be "the first preemptable amount is larger than the second preemptable amount". The second predetermined difference condition may be "the number of second preemptible amounts having a difference from the corresponding first preemptible amount greater than a preset threshold is greater than a preset number" among the respective second preemptible amounts. Here, the setting of the preset threshold and the preset number is not limited. In practice, the execution main body may determine the remaining expiration time corresponding to the stock preemption information corresponding to the first preemptable amount to be zero, so that the stock preemption information is expiration stock preemption information. The remaining expiration time may be a time from a current time to a time at which the stock preemption information expires. It is understood that, in response to determining that the expired inventory preemption information corresponding to the item information exists in the memory database, the execution main body may determine that the inventory preemption information corresponding to the item information does not exist in the memory database, and may further create the inventory preemption information corresponding to the item information. Therefore, when the first pre-occupation amount exceeds the second pre-occupation amount or the difference between the second pre-occupation amount and the first pre-occupation amount meets the condition, the corresponding stock pre-occupation information is determined as the expired stock pre-occupation information, so that when the expired stock pre-occupation information is read, new stock pre-occupation information is created to correct the expired stock pre-occupation information.
As can be seen in fig. 4, the flow 400 of the inventory preemption method in some embodiments corresponding to fig. 4 embodies the steps of extending the creation of inventory preemption information and the determination of stale inventory preemption information as compared to the description of some embodiments corresponding to fig. 3. Therefore, the solutions described in the embodiments can initialize the memory database without the stock preemption information corresponding to the article information in the memory database. Meanwhile, when the first pre-occupation amount exceeds the second pre-occupation amount or the difference between the second pre-occupation amount and the first pre-occupation amount meets the condition, the corresponding stock pre-occupation information is determined as the expired stock pre-occupation information, so that when the expired stock pre-occupation information is read, new stock pre-occupation information is created to correct the expired stock pre-occupation information. Thus, the number of times the number of sold articles exceeds the stock amount can be reduced.
