All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As in the prior art, each inventory query request is concentrated on a redis cluster, but resources of the redis cluster are limited, and a response speed will be slow in the face of a large number of query requests, and for a user, a situation that an access speed is slow and shopping efficiency is reduced will occur, as shown in fig. 1, an embodiment of the present invention provides a resource processing method, which may be applied to a server, where the server may be communicatively connected to the redis cluster, and the redis cluster includes a plurality of hosts, where the method may include the following steps:
step S101, receiving an inventory inquiry request.
In the embodiment of the present invention, the inventory query request includes a product identifier, where the product identifier may refer to a product ID, and the inventory query request may be sent from a client to a server.
And step S102, inquiring whether the commodity identification is located in an inventory-free set cached locally.
In the embodiment of the invention, the inventory-free set comprises the commodity identification of local inventory-free commodities;
in the embodiment of the present invention, the non-inventory set may be cached locally in the server in advance, and the non-inventory set is set to share the pressure that the redis cluster is accessed at a high speed, and when a certain commodity of the redis cluster is actually out of inventory, if the access to the redis cluster is still requested, the resource of the redis cluster is occupied, and the access speed is reduced.
And step S103, if the commodity identification is located in the stock-free set, returning first notification information.
In the embodiment of the present invention, the first notification information may be negotiated with the client in advance, and when the local inventory is insufficient, the first notification information is returned to the client; the client may also set a stock field in the first notification information, assign the stock field as out, analyze the first notification information after receiving the first notification information, and obtain the value of the stock field as out, so that the local inventory deficiency may be known.
In the embodiment of the invention, an inventory query request carrying a commodity identifier is received firstly, and then whether the commodity identifier is located in an inventory-free set cached locally is queried, if the commodity identifier is located in the inventory-free set, first notification information can be returned.
In the embodiment of the invention, if the commodity identification is located in the inventory-free set of the local cache, the commodity identification indicates that the commodity has no inventory locally, and the first notification information can be returned.
The redis cluster is a non-relational database of a high-performance key-value pair (key-value), wherein a key is generally used for storing a commodity identifier, a value is used for storing inventory, when a high-concurrency scene of a request occurs, such as when a certain popular commodity is discounted, inventory query requests are all concentrated on a certain specific key on the redis cluster, and the specific key is accessed too many times, so that the traffic is excessively concentrated, the upper limit of a physical network card is reached, and the server of the redis database is down. To this end, in a further embodiment of the present invention, a preset primary count field for stock quantity deduction may be provided for each of the commodity identifications, the preset primary count field corresponding to a plurality of preset secondary count fields for stock quantity inquiry, the stock quantity in the preset secondary count field being synchronized with the stock quantity in the preset primary count field.
Based on the above, when stock deduction is needed, deducting the stock in the preset main counting field, and synchronizing the stock to the corresponding multiple preset auxiliary counting fields so as to ensure the accuracy of stock inquiry in the preset auxiliary counting fields; when the inventory query request is received, query can be performed in the inventory of one preset secondary counting field with the least current request quantity according to a load balancing principle, a pin hash value or a random strategy and the like, and the pressure of the high-concurrency inventory query request is shared by the plurality of preset secondary counting fields, so that the inventory query request is prevented from being concentrated on one key.
In practical application, the plurality of preset sub-count fields may be stored in different hosts of the redis cluster, so that when querying is performed in the inventory of one preset sub-count field with the smallest number of current requests, the query may be performed in different hosts, and the multiple hosts are used to share the pressure of highly concurrent inventory query requests, thereby preventing the inventory query requests from being concentrated on one host.
In another embodiment provided by the present invention, a preferred implementation is provided, and as shown in fig. 2, the resource processing method further includes:
step S201, if the product identifier is not located in the stock-free set, querying whether the product identifier is located in a locally cached stock set.
In the embodiment of the invention, the inventory set comprises a commodity identifier of a local inventory commodity and a local inventory corresponding to the commodity identifier;
in the embodiment of the present invention, the inventory set may be cached locally in the server in advance, and the purpose of setting the inventory set is to share the pressure that the redis cluster is accessed at a high speed, and when a certain commodity of the redis cluster is actually stored locally, if the reds cluster is still requested to be accessed, the resource of the redis cluster is occupied, and the access speed is reduced.
Step S202, if the commodity identification is located in an inventory set of a local cache and the local inventory corresponding to the commodity identification is greater than 0, deducting the inventory in a preset main counting number field corresponding to the commodity identification;
in step S203, if the stock quantity deduction in the preset main design number field is successful, the second notification information is returned.
In the embodiment of the present invention, the second notification information may be negotiated with the client in advance, and when the second notification information is stored locally, the second notification information is returned to the client; it is also possible to have specific fields set in the second notification message, such as: the value of the stock field is assigned to be in, the client receives the second notification information, analyzes the second notification information, and obtains the value of the stock field as in, that is, it can know that the stock is locally stored, and in practical application, other implementation manners can be set according to practical situations, which is not limited herein.
In the embodiment of the invention, if the commodity identification is located in the inventory set of the local cache, the commodity is in the local inventory, the inventory can be reduced, and the second notification information is returned.
In another embodiment of the present invention, if the stock reduction in the preset main design number field is successful, the method may further include:
and step S204, synchronizing the stock quantity in the preset main counting field after the stock quantity is deducted to the preset auxiliary counting field.
Because the stock in the preset main counting field is changed after the stock is deducted, in order to ensure the accuracy of the query result obtained by the subsequent stock query request, the stock in the preset main counting field after the stock is deducted can be synchronized to the plurality of corresponding auxiliary counting fields, so that the accurate query result can be obtained based on the data after the stock is deducted during the subsequent stock query request.
In another embodiment of the present invention, as shown in fig. 3, the resource processing method further includes:
step S301, if the inventory reduction in the preset main design number field fails, returning first notification information;
step S302, deleting the commodity identification and the corresponding local inventory in an inventory set, and adding the commodity identification into the inventory-free set;
in the embodiment of the present invention, the failure of deducting the stock may be due to limited stock, and under a high concurrent query request, there may be a large amount of rapid stock deductions, and due to network delay and other situations, a situation that the stock of an actual commodity is insufficient although the commodity identifier is still in the stock set may occur, so that the first notification information may be returned, the commodity identifier is deleted from the stock set and added to the stock-free set, data update is implemented, and a result that a user obtains delayed information and causes poor user experience is avoided.
In another embodiment of the present invention, as shown in fig. 4, the resource processing method further includes:
step S401, if the commodity identification is not located in the inventory set, determining a target preset sub-counting field in a plurality of preset sub-counting fields corresponding to the commodity identification according to a preset copy distribution strategy;
in this embodiment of the present invention, if the commodity identifier is not located in the inventory set, a target preset sub-count field may be determined from a plurality of preset sub-count fields stored in a plurality of hosts of a redis cluster according to a load balancing policy, a pin hash value, or a random allocation policy, for example.
Step S402, if the stock quantity is inquired to be larger than 0 in the target preset secondary counting field, the step of deducting the stock quantity in the preset main counting field corresponding to the commodity identification is executed;
in the embodiment of the invention, because the inventory in the main counting field and the plurality of corresponding secondary counting fields is the total inventory of the commodities corresponding to the commodity identifications in the redis cluster, the inventory in the target preset secondary counting field is also the total inventory of the commodities, and the inventory in the target secondary counting field can be inquired when the inventory in both the non-inventory set and the inventory set of the local cache is insufficient.
And if the target preset secondary counting field has the inventory, executing the step of deducting the inventory in the preset main counting field corresponding to the commodity identification, and if the inventory deduction in the preset main counting field succeeds, returning second notification information and synchronizing the inventory in the preset main counting field after the inventory deduction to the preset secondary counting field.
Step S403, synchronizing the stock quantity in the preset main counting number field after the stock quantity deduction to the stock-free set or the stock set cached locally.
In the embodiment of the present invention, if the inventory in the preset main counting field after deducting the inventory is 0, the commodity identifier may be added to the inventory-free set of the local cache, and if the inventory in the preset main counting field after deducting the inventory is greater than 0, the inventory in the preset main counting field after deducting the inventory may be calculated according to a preset local inventory allocation manner and then synchronized to the preset sub counting field.
The inventory in the preset main counting number field after the inventory is deducted is synchronized, local non-inventory collection or inventory collection data updating is realized, the condition that subsequent inventory inquiry requests acquire lagging information is avoided, the inventory information of commodities can be acquired from the local conveniently, the request response efficiency is improved while the server access pressure is reduced, and a user can receive response information at a higher speed conveniently.
Based on the above, the local inventory query efficiency is much higher than that of direct query in redis, the performance improvement effect is obvious, but the data synchronization problem is also brought, so the following embodiment provides a plurality of allocation strategies to avoid reducing the asynchronous problem when allocating the local cache, and the inventory query is verified again when passing the back deduction, so that the situation that a small amount of inventory passes through but the actual inventory is consumed occurs, and the situation is reduced by reasonably using the strategies.
In another embodiment of the present invention, a method for allocating an inventory amount in a local cache is further provided, as shown in fig. 5, where the resource processing method further includes:
step S501, acquiring the stock in a preset main counting number field corresponding to the commodity identification;
step S502, calculating the product of the inventory and the preset distribution percentage;
step S503, determining the quotient of the product and the number of hosts in the cluster as the local inventory amount corresponding to the commodity identifier.
In the embodiment of the present invention, the distribution percentage may be determined according to actual needs, for example: the total inventory amount is 100, the distribution percentage is 30%, the number of hosts in the redis cluster is 10, namely the redis inventory amount is 100, and the local inventory amount of the local cache of the server is 100 × 0.3/10 — 3.
When the local inventory of the local cache of the server is exhausted, the residual quantity is synchronously distributed to the local inventory of the local cache of the server according to the distribution percentage, the distribution is not carried out when the distribution is less than 1, the specific distribution mode is changed according to the actual condition, and the invention is not limited.
In another embodiment of the present invention, the resource may also be allocated according to a fixed allocation policy, as shown in fig. 6, where the resource processing method further includes:
step S601, acquiring the stock in a preset main counting number field corresponding to the commodity identification;
step S602, calculating the quotient of the stock quantity and the number of the hosts in the cluster;
step S603, determining the local inventory corresponding to the commodity identifier as a preset fixed quantity, where the preset fixed quantity is less than or equal to the quotient.
That is to say, the local inventory corresponding to the commodity identifier is a preset fixed quantity, and the preset fixed quantity is less than or equal to the quotient of the inventory in the preset main counting number section corresponding to the commodity identifier and the quantity of the hosts in the cluster;
in another embodiment of the present invention, a dynamic allocation policy may also be adopted, as shown in fig. 7, the resource processing method further includes:
step S701, allocating a first preset amount of inventory for each host in the cluster, and recording allocation time;
step S702, when the stock distribution is to be carried out again, calculating the stock distribution quantity per second of the host;
step S703, if the allocation amount per second is less than or equal to 1, allocating the stock amount to the host again according to the first preset amount;
step S704, if the distribution quantity per second is larger than 1 and smaller than a preset distribution reference quantity, the stock quantity is distributed to the host again according to the distribution quantity per second, the distribution reference quantity is a product obtained by multiplying the stock quantity in a preset main counting number section corresponding to the commodity identification and the number of the hosts in the cluster by a preset percentage, and the distribution reference quantity is larger than 1;
step S705, if the allocation amount per second is greater than the allocation reference amount, allocating the stock amount again to the host according to the allocation reference amount.
In the embodiment of the present invention, a dynamic allocation policy is adopted, the stock quantity is allocated for the host in the cluster for the first time, the data may be determined according to the actual situation, or the allocation manner described in the above embodiment may be adopted, and when the stock distribution is performed again, the stock quantity is allocated for the host again according to the allocation reference quantity, for example: and calculating the distribution quantity of the hosts per second, if the distribution quantity of the hosts per second is less than or equal to 1, continuing to distribute 1 inventory, otherwise, distributing the quantity per second, and if the distribution quantity is more than one third of the total inventory quantity/host quantity, distributing one third of the quantity (total inventory quantity/host quantity).
