Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. 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 invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the embodiment of the invention, a hierarchical control mode is adopted to accurately control the quota of the account, and the complexity of the whole system is not increased. The following detailed description is made with reference to the accompanying drawings. FIG. 1 is a diagram illustrating the main steps of a method for managing an amount according to an embodiment of the present invention.
Step 101: and receiving a request of transaction operation sent by a user.
The user is a data demand party, and sends a data transaction operation request through the data transaction system to request to obtain certain specific data through the account amount. For example, a data consumer needs advertisement data, generating a request for a transaction operation with the advertisement data.
Step 102: and selecting a target node meeting the transaction range condition from the node tree corresponding to the account of the user.
For the same user, there may be one main account and multiple sub-accounts, and among all the main accounts and sub-accounts, the account capable of data transaction is divided into nodes, and a node tree corresponding to the user is generated. In the initial case, the user applies for the primary account first, and then applies for the secondary account according to the transaction scope. And applying for accounts according to the range of available transactions, wherein the accounts comprise a main account and sub-accounts, and each account is a node. The business account can continue to generate sub business accounts, namely sub nodes according to the reduced product range, so that a node tree divided by the transaction range is formed. Each user typically corresponds to a tree of nodes. In the embodiment of the present invention, a user generally has a primary account, and thus, a user corresponds to a node tree, the primary account corresponds to a root node of the node tree, and the sub-account corresponds to a child node of the node tree. In the node tree corresponding to the user, each node corresponds to a certain transaction range, and data transaction can be performed within the transaction range corresponding to the node, for example, a certain node can perform data transaction with a certain data provider or certain specific data providers. The request of the transaction operation corresponds to a specific transaction range, for example, data provided by a specific data provider is needed, and before the request of the corresponding transaction operation, a node corresponding to the transaction range of the request of the current transaction operation needs to be searched. In a node tree, at least one node meeting the transaction range condition may exist, and one of the nodes meeting the transaction range condition is selected as a target node, and the target node provides a required quota for the transaction operation.
The target node may be a child node or a root node.
When no node meeting the transaction range condition exists in the node tree, the related information of transaction failure is returned, then the user can be prompted to register a new sub-account, a new sub-account is generated for the user, and then a new child node capable of meeting the transaction range condition is correspondingly established in the node tree.
Step 103: and if the quota of the target node can meet the transaction operation, executing the transaction operation.
The user obtains a certain amount by charging the account, accepting the giving operation of another account, the credit giving operation and the like, if the amount of the selected target node can meet the request of the transaction operation, the transaction operation is directly executed, and the amount consumed by the transaction operation is deducted from the amount of the target node.
Step 104: and if the quota of the target node cannot meet the transaction operation, applying for a corresponding quota through a quota control center, adding the applied quota to the total quota of the target node after the successful application, and then executing the transaction operation.
After the target node is selected, the amount required by the transaction operation is directly deducted from the amount of the target node, and the new amount is applied for the target node after the transaction operation is completed, so that the amounts of the main account and the sub-account of the user are not influenced with each other, and the amount control is simpler.
The quota applied by the node of the node tree can be used only when the node is used as a target node of a request of certain transaction operation, and the node can be applied after the quota is used up, so that the condition that the actual expense of the account exceeds the quota of the account can be avoided.
In the step of applying for the corresponding quota through the quota control center, the quota applied is adapted to the transaction operation and can be determined by means of prediction and the like.
The step of executing the transaction operation specifically includes all steps necessary for executing the transaction operation, for example, sending a data request corresponding to executing the transaction operation to a data provider, receiving data feedback information provided by the data provider, sending the data feedback information to a set receiving module, and the like.
In the embodiment of the invention, when the target node carries out transaction, if the limit is not enough, the node applies for the limit to the limit control center, and generally carries out pre-estimated limit application according to the business volume and the price of transaction operation. When a plurality of transaction operations occur to a user account, the transaction operations respectively acquire the quota required by the transaction on the corresponding target nodes, and because the target nodes can not apply for the quota to the quota center through the root node, when the requests of the transaction operations are sent out simultaneously, the conditions of competing the same quota data do not occur, the problem that more and more requests of other transaction operations can not be responded in time along with the normal response time is avoided, and the system congestion is effectively avoided. In a highly concurrent data transaction system, the embodiment of the invention selects the target node to execute the transaction operation according to the range corresponding to the request of the transaction operation, reduces the frequent access and update of some data by mass users in a short time, shortens the response time, improves the response speed, and avoids the breakdown of the data transaction system caused by the avalanche effect generated by the requests of the users for multiple times of the same transaction operation when the response is slow.
In some embodiments of the present invention, the step of selecting a target node that satisfies the transaction scope condition from a node tree corresponding to the account of the user includes:
searching nodes meeting the transaction range condition in leaf nodes of the node tree, and if the nodes are found, selecting the nodes as target nodes; if not, entering the following steps;
searching non-leaf nodes meeting the transaction range condition in the child nodes, and if the non-leaf nodes are found, selecting the non-leaf nodes as target nodes; if not, entering the following steps;
and judging whether the root node meets the transaction range condition, if so, selecting the root node as a target node.
The transaction range may correspond to a request for a transaction operation, and may be recorded in the request for a transaction operation. In the embodiment of the invention, the trading nodes are selected according to the minimum matching principle of the trading range, namely the leaf nodes have the trading priority. Therefore, all transaction operations are distributed to different nodes as much as possible, the nodes with large transaction range are prevented from bearing excessive transaction operation tasks, congestion is further avoided, and processing efficiency is improved.
In some embodiments of the present invention, after the step of performing the transaction operation, the method further includes:
deducting the credit consumed for executing the transaction operation from the total credit of the target node to obtain a remaining credit;
recording the surplus limit into a distribution log of the target node;
after the set time is reached, calculating the settlement amount of the account according to the distribution log;
updating the account quota according to the settlement quota;
and sending the updated quota of the account to the quota control center.
In the embodiment of the invention, each node can acquire a certain amount for transaction operation in the modes of cash recharging, platform giving, platform credit granting and the like before transaction operation, and the amount can be gradually consumed after the transaction operation is executed. All nodes respectively calculate the amount consumed for executing corresponding transaction operation, then the amount calculated by each node is sent to an amount control center for gathering, the amount counting and the real account settlement are separately performed, the account settlement generates a distribution log according to the real distribution amount, the times of transaction operation requests of the account of a data demand party are recorded in the distribution log, then the settlement amount of the account is calculated according to the distribution log, the expenses of all accounts of a user are gathered to obtain the total expense of all sub-accounts and main accounts of the user, and in the amount control center, the residual amount of the user is the initial amount minus the total expense. The method can avoid repeated calculation and ensure the accuracy of the calculation of the quota.
In some embodiments of the present invention, the step of applying for the corresponding credit through the credit control center includes:
sending limit application information to a limit control center, and applying for a corresponding limit from a limit pool corresponding to the node tree;
locking the limit pool to ensure that the limit control center refuses to respond to other limit application information after receiving the other limit application information of the user;
receiving information of successful credit application;
and unlocking the limit pool, so that the limit control center can respond to the other limit application information after receiving the other limit application information.
In the prior art, in a high concurrency scenario, multiple requests sent by multiple processes are simultaneously distributed to multiple servers in an intranet through load balancing, and before a certain request is successfully written into a database, query results of other requests may be in a state before writing, which may cause system misjudgment.
In the embodiment of the invention, when transaction operation is executed, the amount of the target node is deducted, and the embodiment of the invention introduces a locking mechanism, and accounts of the same user share an amount pool, namely a node share amount pool of the same node tree. Only one quota application message is processed at one time, other quota application messages are discharged when one quota application message is processed, and the condition that multiple processes simultaneously compete for the same quota data due to the introduction of a locking mechanism when a plurality of sub-accounts simultaneously apply for the quota can not occur.
The processing components related to the present invention mainly include a DMP (Data Management Platform), a DLS (Data link Service, a portal for providing Data transaction services to members by a Data transaction center), a DMIX (Data distribution System), a DAS (Data Analysis System), a Redis cluster, a CAP product (Chinese Audience image library), a CRP product (Credit Risk image library), and a line control center.

Redis is a key-Value storage system that supports the storage of data in some structures, such as Value structures. The Redis cluster provides convenient and fast data caching service, and is used for realizing process communication and caching data in a system. When the request of transaction operation is processed, the target node firstly inquires the quota in the Redis cache of the target node, and if the quota is insufficient, the quota is requested to the quota control center.
CAP product: is a standardized data product oriented to the marketing industry. The main user groups are advertisers, 4A advertising agent companies, DSP data delivery enterprises and the like, and various services such as user portraits before advertisement delivery, data completion during delivery, data verification after delivery and the like are provided for the users.
