Based on the above hardware structure, an embodiment of the data batch processing method based on the blockchain of this application is proposed.

Referring to Fig. 2, Fig. 2 is a schematic flow chart of the first embodiment of a blockchain-based data batch processing method according to this application. The blockchain-based data batch processing method includes:

Step S10, after receiving the batch data recording request, determine each data recording request unit in the multiple blockchain nodes corresponding to the batch data record, and according to the preset hotspot configuration table, in each data recording request unit Determine the hotspot unit;

In this embodiment, a financial business scenario is used as an example for illustration. In a specific embodiment, the solution in this application can also be applied to other application scenarios. Wherein, the data recording request is a billing request, the data recording request unit is a billing request account, and the hotspot unit is a hotspot account.

At present, in certain specific financial business scenarios, it is necessary to perform concurrent accounting processing on a single account. In this case, the account becomes a hot account. For example, when a user makes an online payment for a product, the user can use his payment account to pay the amount of the product to the secured transaction intermediate account. When each user makes an online payment, the secured transaction intermediate account will be involved. When a large number of users make online payments within a period of time, the secured transaction intermediate account will become a hot account. Existing hotspot accounts are accounted in a synchronous mode, that is, when transactions are executed, hotspot accounts need to be locked/unlocked, which makes a large number of concurrent transaction requests need to be queued and waited to be processed by hotspot accounts, resulting in a large number of concurrent transaction requests being serialized , Which greatly reduces the efficiency of data processing. In order to solve the above problems, in this embodiment, batch processing of billing requests is performed, the transaction flow corresponding to the hot account is synchronized to the pending flow list of the hot node, the transaction flow of the hot account is synchronously recorded, and then the hot account is performed according to the pending flow list Asynchronous update of balance and other non-balance processing operations. This improves the transaction processing efficiency of hot accounts and improves the success rate of multi-node account transactions. Specifically, the hotspot configuration table is preset, including the node routing information to which the hotspot account belongs, the allowed processing type of the hotspot account (debit hotspot, credit hotspot), current control status (judicial, bank control), account balance corresponding to the alert status, and alert Recover account balance threshold, pause status indicator, pause recovery account balance threshold, etc., and synchronize the hotspot configuration table to each node. When receiving the billing request, obtain both parties of the billing request, and send the billing transaction request to the relevant node where both parties are located. If the two parties involved in the bookkeeping only involve a single node, then the bookkeeping transaction request will be sent to the hotspot node, that is, the node to which the hot account belongs; if the two parties involved in the bookkeeping involve multiple nodes, the transaction request will be sent to the non-hotspot node to reduce synchronization Operation, avoid cross-node calls. If both parties to the account involve multiple nodes and both are hot nodes, the transaction is sent to any hot node. Through the above method, the multi-node accounting process is simplified to the single-node accounting process. Before performing the accounting processing operation, it is necessary to identify whether the accounting request account is a hot account or a non-hot account, perform synchronous accounting for the non-hot account, synchronize the registration flow of the hot account, and update the balance asynchronously. Therefore, when a billing request is received, the hotspot configuration table is checked to confirm whether there is a hotspot account in each billing request account. And register the transaction elements in the bookkeeping transaction of the hot account, such as the bookkeeping type, borrowing or transferring amount, etc.

Further, after the step S10, it further includes:

Judging whether the hotspot unit exists in each data recording request unit;

In this embodiment, the value is the balance, and the other non-numerical processing operations are other non-balance processing operations. If there is no hot account in each billing request account, the general mode is processed according to the synchronous real-time balance update, that is, the account balance corresponding to each billing request account and other non-balance processing operations are updated in real time according to the billing request.

Step S20: Obtain the changed data information corresponding to the hotspot unit, and synchronize the changed data information corresponding to the hotspot unit to the hotspot node to which the hotspot unit belongs, and generate a list of data to be changed corresponding to each hotspot node;

In this embodiment, the changed data information is a transaction flow, and the list of data to be changed is a flow list to be processed. Get the transaction flow corresponding to each hotspot account, synchronize the transaction flow corresponding to each hotspot account in each hotspot node to their respective hotspot node, and add the transaction flow corresponding to all hotspot accounts under each hotspot node to each hotspot The pipeline list to be processed corresponding to the node.

Further, before the step S20, it further includes:

If the hotspot unit allows value updating, perform: step S20;

In this embodiment, the hotspot unit status is the hotspot account status, and the value update is the balance update, that is, it is judged whether the hotspot account can conduct transactions. The billing request includes multiple types of billing services. For example, in the hotspot configuration table, the hotspot accounts are respectively set to: allow debit hotspots, allow credit hotspots, or both lending hotspots. The hotspot configuration table also includes control information such as whether each hotspot account is judicially frozen. Therefore, the hotspot account status corresponding to the hotspot account is determined according to the hotspot configuration table, such as whether this type of hotspot is allowed, or whether the account of the hotspot account is in a controlled state, etc., to determine whether each hotspot account is allowed to conduct transactions, if If allowed, step S20 is executed to obtain the to-be-processed pipeline corresponding to each hotspot account. If not allowed, a reminder message of transaction failure is generated.

Step S30, according to the list of data to be changed, update the value of the hot spot unit, and update the value of other non-hot spot units in the hot spot node and other non-hot spot units in other non-hot spot nodes;

In this embodiment, the data list to be changed is the pipeline list to be processed, and the other non-hot-spot units are other non-hot-spot accounts. On each hotspot node, according to the pending flow list corresponding to the hotspot account, the transaction summary of the hotspot account is performed and the account balance of the hotspot account is updated. In a specific embodiment, while updating the account balance of each hotspot account, the billing status of each hotspot account in the hotspot configuration table is further updated according to the updated account balance of each hotspot account. And synchronize the updated hotspot configuration table to all other nodes. As a result, the time difference between the hot account balance update and the corresponding status update is further reduced, so that the balance update and synchronization status change are more timely. Then, it further updates the balance of the corresponding other non-hot-spot accounts in each hot-spot node, and updates the balances of other non-hot-spot accounts in other non-hot-spot nodes, thereby completing the balance update of all billing request accounts.

Step S40: Perform other non-numerical processing operations on each data record request unit according to the list of all changed data after the value is updated to process the data records in batches.

In this embodiment, the all changed data list is a complete flow list, each data record request unit is each billing request account, and the batch processing of the data records is the batch completion of the billing request. After the balance update of all billing request accounts is completed, other non-balance processing operations are moved out. Among them, other non-balance processing operations include inserting, deleting, and modifying multiple records, such as transaction details and accounting parts. For internal accounts involved, the corresponding transaction details and accounting calculations must also be registered, which takes a long time, so the balance is updated Operation and non-balance processing operations are separated to reduce the time difference of balance update, make balance update faster, and state synchronization more accurate.

In this embodiment, after receiving a batch data recording request, each data recording request unit in the multiple blockchain nodes corresponding to the batch data recording is determined, and according to the preset hotspot configuration table, the data recording request unit Determine the hotspot unit; obtain the change data information corresponding to the hotspot unit, and synchronize the change data information corresponding to the hotspot unit to the hotspot node to which the hotspot unit belongs, and generate a list of data to be changed corresponding to each hotspot node; For the list of data to be changed, update the values of the hotspot units, and update the values of other non-hotspot units in the hotspot node and other non-hotspot units in other non-hotspot nodes; according to all the changes after the value update In the data list, other non-numerical processing operations are performed on each data record request unit to process the data records in batches. Through the above method, this application processes data recording requests in batches, synchronizes the change data information corresponding to the hotspot unit to the data list to be changed of the hotspot node, synchronously records the changed data information of the hotspot unit, and then performs the hotspot unit according to the list of data to be changed Asynchronous update of changed data values and other non-numerical processing operations. As a result, the data processing efficiency of the hotspot unit is improved, the success rate of data modification of the multi-node unit is improved, and the technical problem of low data processing efficiency in the existing serial processing method of the hotspot unit is solved.

Further, based on the first embodiment of the blockchain-based data batch processing method of this application, a second embodiment of the blockchain-based data batch processing method of this application is proposed.

In this embodiment, the step S20 specifically includes:

In this embodiment, the list of data to be synchronized is a pipeline to be synchronized, the unsynchronized data is an unsynchronized pipeline, and the list of data to be changed is a pipeline to be processed. In the synchronization processing task, the pending pipeline corresponding to each hot account is recorded, and a list of pipelines to be synchronized is generated, including transaction pipelines corresponding to all hot accounts to be synchronized to their own nodes, wherein each pipeline to be synchronized in the pipeline list to be synchronized The initial state is unsynchronized. Obtain the unsynchronized state transaction flow in the pending synchronization flow list, and when the number of unsynchronized state transaction flow is large, perform the sharding operation, and then synchronize the fragmented unsynchronized state transaction flow to batch Owning hot node. The hotspot node then localizes the received transaction flow and stores it in the to-be-processed flow table, where the billing node directly calls the service through the message bus to perform flow synchronization and failed synchronization retry.

Further, the step S30 specifically includes:

In this embodiment, each change data information is each transaction flow, the unit status of the hotspot unit is the account status of the hotspot account, and the unit value is the account balance. The hotspot configuration table is used as the basis for checking the accounting type permission and accounting status in the accounting synchronization process. There are three situations that will cause the hotspot account status to change and need to be synchronized:

1. Pre-defined settings, that is, the status of each hotspot account preset in the hotspot configuration table;

2. The status change caused by the account balance update, that is, after each hotspot account performs the balance update operation, the account status of each hotspot account needs to be updated, such as the account balance value of each hotspot account is lower than the warning threshold, modify the configuration In the early warning state of the table status, the account balance is lower than the deactivation threshold, modify the deactivated state in the configuration table status. The balance is higher than the early warning recovery threshold, and the normal state in the state of the configuration table is modified.

3. Judicial freezing and other controls lead to changes in the accounting status, that is, judicial and bank controls that make hot accounts untradeable.

Among them, after the status in the configuration table is changed, it needs to be synchronized to other nodes for subsequent synchronization accounting.

Further, according to the respective change data information and the unit status of the corresponding hotspot unit, the hotspot units corresponding to the respective change data information are respectively updated with values, and according to the updated unit values corresponding to each hotspot unit, The step of updating the unit status corresponding to each hotspot unit in the hotspot configuration table specifically includes:

In this embodiment, before updating the balance of the hotspot account according to the transaction flow corresponding to each hotspot account, it is necessary to determine whether the hotspot account can perform a transaction operation for the amount corresponding to the transaction flow. Specifically, the transaction flow details in the synchronously recorded transaction flow are sequentially obtained, that is, each transaction flow is sequentially used as the flow to be updated, and the hot accounts corresponding to the transaction flow details are correspondingly processed. The hot account corresponding to the transaction flow details is used as the hot account to be updated corresponding to the brother's to be updated flow. According to the amount to be updated corresponding to the flow to be updated, that is, the transaction amount, and the account balance status of the hot account to be updated, such as a suspended status, a balance warning status, or a normal status (balance sufficient status). It is judged whether the balance of the hot account to be updated can be updated, that is, it is judged whether the amount to be updated is less than the account balance of the hot account to be updated. If the amount to be updated is less than or equal to the account balance of the hotspot account to be updated, the balance update operation can be performed, the hotspot account to be updated is locked, and the pending update status of the flow to be updated is changed to already Update the status, update the balance of the hotspot account to be updated, and update the account balance status corresponding to the hotspot account to be updated in the hotspot configuration table. If the amount to be updated is greater than the account balance of the hotspot account to be updated, the balance update operation cannot be performed, and a transaction failure reminder message corresponding to the hotspot account is generated.

Further, based on the second embodiment of the blockchain-based data batch processing method of this application, a third embodiment of the blockchain-based data batch processing method of this application is proposed.

In this embodiment, before the step S30, the method further includes:

In this embodiment, each change data information identifier is each transaction flow identifier, the repeated change data information identifier is a repeated flow identifier, and each change data information is each transaction flow identifier. In order to improve the processing efficiency and accuracy of the change data, that is, to improve the processing efficiency and accuracy of the accounting data, specifically, each asynchronous task is deduplicated and failed retry processing. Among them, asynchronous tasks include balance updates, other non-balance processing operations, etc. Specifically, in order to improve the efficiency of balance update, when obtaining the balance update asynchronous task, obtain the pending flow list corresponding to the balance update asynchronous task, and obtain each transaction flow identifier in the pending flow list, where each transaction The flow corresponds to a unique transaction flow identifier, such as a trading flow number or a trading flow name. It is judged whether there is a repeated flow mark in each transaction flow mark, that is, it is judged whether there are two or more identical transaction flow marks in each transaction flow mark. If there is a repeated flow mark in each transaction flow mark, the repeated flow mark corresponding to the repeated flow mark is de-duplicated, so that each trading flow in the pending flow list is a unique trading flow. In a specific embodiment, when it is detected that the balance update task corresponding to each transaction flow in the pending flow list has failed, the balance update task corresponding to the transaction flow is restarted and executed according to a preset time interval.
