Description

Distributed transaction processing method, device, equipment and storage medium

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a distributed transaction processing method, apparatus, device, and storage medium.

Background

A distributed system is a system whose components reside on different networked computers, communicating and coordinating by passing messages to each other. Under the distributed micro-service architecture, how to ensure that transactions distributed in different computing nodes are all successful or all failed is a problem that the distributed transaction needs to solve.

In the prior art, distributed transactions are typically handled by a simple scalable autonomous transaction framework (Simple Extensibl e Autonomous Transaction Architecture, seata). The basic components in the Seata include a transaction Manager (Transaction Manager, TM), a transaction coordinator (Transaction Coordinator, TC), and a Resource Manager (RM). Currently, seata can support SAGA and resource reservation-acknowledgement-revocation (TCC) transaction modes.

However, existing Seata only supports distributed transactions in a single transaction mode. When SAGA mode transaction and TCC mode transaction exist in the transaction processing chain at the same time, the SAGA transaction and TCC transaction can only be manually submitted by a teller, so that the method is complicated and complex, and the workload of the teller is increased. For scenarios like SAGA transactions invoking TCC transactions, the entire transaction processing chain needs to be changed to TCC mode entirely, resulting in wasted program development resources.

Example 1

Fig. 1 is a flowchart of a distributed transaction processing method according to an embodiment of the present invention, where the method may be performed by a distributed transaction processing device, and the distributed transaction processing device may be implemented in hardware and/or software, and the distributed transaction processing device may be configured in an electronic device, such as a computer.

As shown in fig. 1, the distributed transaction processing method disclosed in this embodiment is applied to a transaction coordinator, and the method includes:

s110, acquiring a global transaction opening request sent by a transaction manager, and generating a first global transaction identifier according to the global transaction opening request.

In this embodiment, the transaction manager may be used to open, commit or revoke distributed transactions. A distributed transaction (i.e., a global transaction) may be made up of multiple branch transactions. The transaction manager can ensure the transaction consistency of the distributed system by uniformly coordinating all branch transactions.

At this step, specifically, a global transaction initiation request may be sent to the transaction coordinator by the transaction manager after the application sends a distributed transaction request to the transaction manager. Then, a first global transaction identification is generated by the transaction coordinator according to the global transaction initiation request. The first global transaction identification may be used to associate a plurality of branch transactions.

S120, acquiring a plurality of branch transactions registered by the resource manager, and generating a second global transaction identifier according to the transaction mode corresponding to each branch transaction.

Wherein the transaction mode is SAGA mode or TTC mode.

In this embodiment, the first global transaction identifier and the second global transaction identifier may be used to partition branch transactions of different transaction modes. The transaction pattern of each branch transaction corresponding to the second global transaction identification is different from the transaction pattern of each branch transaction corresponding to the first global identification.

At this step, specifically, a second global transaction identifier may be generated according to the registration order and transaction mode of each branch transaction.

For example, after the resource manager registers the first branch transaction, a first global transaction identification may be set for the first branch transaction. After the resource manager registers the second branch transaction, whether to generate the second global transaction identifier can be judged according to the transaction mode corresponding to the second branch transaction. And if the transaction mode corresponding to the second branch transaction is the same as the transaction mode corresponding to the first branch transaction, setting a second global transaction identifier for the second branch transaction. If the transaction pattern corresponding to the second branch transaction is different from the transaction pattern corresponding to the first branch transaction, a second global transaction identification may be generated.

S130, distributing each branch transaction to a first transaction chain corresponding to the first global transaction identifier and a second transaction chain corresponding to the second global transaction identifier.

In this embodiment, the first transaction chain and the second transaction chain may be micro-service invocation links.

In this step, specifically, each branch transaction may be allocated to the first transaction chain or the second transaction chain according to the global transaction identifier corresponding to each branch transaction.

S140, acquiring transaction processing requests sent by the transaction managers according to the states of the resource managers, and processing all the transactions in the first transaction chain and all the transactions in the second transaction chain in sequence according to the transaction processing requests.

In this embodiment, the state of the resource manager may include the preparation of completed and completed branch transactions. The transaction request may include global transaction commit, global transaction undo, and the like. Since the SAGA mode is not suitable for a scenario requiring a risk of funds, and the TCC mode is suitable for a scenario requiring a risk of funds, the branch transactions of the TCC mode may be processed after all the branch transactions of the SAGA mode have been processed.

In one embodiment, the status of each resource manager may be sent to the resource manager. Then, a global transaction commit request or a global transaction undo request may be sent to the transaction coordinator by the resource managers according to the state of each resource manager. For example, if each resource manager has completed preparation for the corresponding branch transaction, a global commit request may be sent. If any resource manager does not complete preparation of the corresponding branch transaction, a global revocation request may be sent.

If the transaction mode of the branch transaction in the first transaction chain is SAGA mode and the transaction mode of the branch transaction in the second transaction chain is TCC mode, all the branch transactions in the first transaction chain can be processed in sequence according to the sequence of the distribution of each branch transaction to the first transaction chain. After all the branch transactions in the first transaction chain are processed, all the branch transactions in the second transaction chain are processed according to the sequence of the distribution of the branch transactions to the second transaction chain.

Illustratively, it is assumed that the combined transaction (i.e., the distributed transaction) includes the following branching transactions: 1000 yuan of deduction is carried out from an account A, 1000 yuan of cash is stored in a user counter, the user counter is transferred to a user account 1980 yuan, and a 20 yuan of commission is charged, so that the account deduction operation is S1, the counter cash deposit operation is S21, the cash box transaction is S22, the user counter is transferred to the user account to be T1, and the commission charge is S3. Because the account deduction operation, counter cash deposit operation, cash box transaction and commission charge are no fund risk for the internal account transaction, and the fund risk exists for transferring into the user account, the transaction mode corresponding to S1, S21, S22 and S3 can be set as SAGA mode, and the transaction mode corresponding to T1 is set as TCC mode. Then, S1, S21, S22, and S3 may be sequentially added to the first transaction chain, and T1 may be added to the second transaction chain. Finally, T1 may be processed after processing S1, S21, S22, and S3 in order. When the transaction request is a global transaction retraction request, T1 may be retracted after submitting the compensation transactions of S3, S22, S21 and S1 in reverse order according to the first transaction chain.

The advantage of setting like this is that, because SAGA mode has the program development volume little, nevertheless has trade inconsistent probably, is unsuitable for the characteristics of the scene that requires fund safety, and TCC mode has the program development volume big, does not have trade inconsistent risk, is suitable for the characteristics of the scene that requires fund safety. Therefore, in practical applications, it is generally required to implement in SAGA mode in a non-funding risk scenario to reduce the development amount of the program, and in TCC mode in a funding risk scenario to avoid the funding risk. According to the technical scheme, the first global transaction identifier and the second global transaction identifier are generated through the transaction mode corresponding to each branch transaction, each branch transaction is distributed to the first transaction chain corresponding to the first global transaction identifier and the second transaction chain corresponding to the second global transaction identifier, all transactions in the first transaction chain and all transactions in the second transaction chain are sequentially processed, and the method can be suitable for the situation that SAGA mode branch transactions and TCC mode branch transactions exist in distributed transactions at the same time, the consistency of the distributed transactions is guaranteed, and the complexity and cost of processing the distributed transactions are reduced. Secondly, compared with the prior art that the distributed implementation mode of the whole distributed transaction is required to be changed into the TCC mode, the technical scheme of the embodiment saves program development resources.

According to the technical scheme of the embodiment, a global transaction starting request sent by a transaction manager is obtained, and a first global transaction identifier is generated according to the global transaction starting request; acquiring a plurality of branch transactions registered by a resource manager, and generating a second global transaction identifier according to transaction modes corresponding to the branch transactions; the transaction mode is SAGA mode or TTC mode; distributing each branch transaction to a first transaction chain corresponding to a first global transaction identifier and a second transaction chain corresponding to a second global transaction identifier; the technical means that transaction managers sequentially process all transactions in a first transaction chain and all transactions in a second transaction chain according to transaction processing requests, and the technical means that the conventional Seata only supports single-mode distributed transactions is solved, so that when SAGA mode transactions and TCC mode transactions exist in a transaction processing chain at the same time, the problem that SAGA transactions and TCC transactions can only be submitted manually by a teller is solved.

Example two

Fig. 2 is a flowchart of another distributed transaction processing method according to a second embodiment of the present invention, which is based on further optimization and expansion of the above embodiments and may be combined with various alternative solutions in the above embodiments.

As shown in fig. 2, a distributed transaction processing method disclosed in this embodiment includes:

s210, acquiring a global transaction opening request sent by a transaction manager, and generating a first global transaction identifier according to the global transaction opening request.

S220, acquiring service characteristics corresponding to each branch transaction registered by the resource manager, and determining a transaction mode corresponding to each branch transaction according to the service characteristics corresponding to each branch transaction.

In this embodiment, the business characteristics may include a risk of having funds, a risk of not having funds, and the like. Branch transactions without a risk of funds may include individual account deductions, counter cash deposits, cash box transactions, and commission authorizations, among others. The funding branch transaction may include a personal account posting, or the like. In practical applications, a branch transaction that does not involve user funds may be referred to as a SAGA mode branch transaction, and a branch transaction that involves user funds may be referred to as a TCC mode branch transaction.

In this step, specifically, if the branch transaction registered by the resource manager has a fund risk, it may be determined that the transaction mode corresponding to the branch transaction is a SAGA mode. If the branch transaction registered by the resource manager has no fund risk, the transaction mode corresponding to the branch transaction can be determined to be TCC mode.

S230, generating a second global transaction identifier according to the transaction mode corresponding to each branch transaction.

In an optional implementation manner of the embodiment of the present invention, generating the second global transaction identifier according to the transaction mode corresponding to each branch transaction includes: acquiring transaction modes corresponding to historical branch transactions, and judging whether the transaction mode corresponding to the current branch transaction is the same as the transaction mode corresponding to each historical branch transaction; if not, a second global transaction identification is generated.

In this embodiment, the historical branch transactions may be branch transactions registered by the resource manager prior to the current branch transaction. Specifically, if the transaction pattern corresponding to the branch transaction before the branch transaction is the same as the transaction pattern corresponding to each historical branch transaction, only the first global transaction identifier may be generated.

Optionally, in the case that the first global transaction identifier and the second global transaction identifier have been generated, if the transaction mode of the current branch transaction is different from the transaction mode corresponding to the historical branch transaction, a third global transaction identifier may be generated.

S240, judging whether the transaction mode corresponding to the current branch transaction is the first branch transaction, if so, executing S250, and if not, executing S260.

In this embodiment, the first branch transaction is the first branch transaction registered by the resource manager.

S250, distributing the current branch transaction to a first transaction chain.

S260, if the transaction mode corresponding to the current branch transaction is the same as the transaction mode corresponding to the first branch transaction, distributing the current branch transaction to a first transaction chain; and if the transaction mode corresponding to the current branch transaction is different from the transaction mode corresponding to the first branch transaction, distributing the current branch transaction to a second transaction chain.

For example, in the case that the transaction mode corresponding to the first branch transaction is the SAGA mode, if the transaction mode corresponding to the current branch transaction is also the SAGA mode, the current branch transaction may be allocated to the first transaction chain. If the transaction mode corresponding to the current branch transaction is TCC mode, the current branch transaction may be assigned to the second transaction chain.

In an alternative implementation of the embodiment of the present invention, the allocating the current branch transaction to the second transaction chain includes: establishing an association relation table, wherein the association relation table comprises a corresponding relation between a first global transaction identifier and a second global transaction identifier; and distributing the current branch transaction to a second transaction chain corresponding to the second global transaction identifier according to the corresponding relation between the first global transaction identifier and the second global transaction identifier.

In this embodiment, optionally, after the first global transaction identifier has been registered by the transaction coordinator, the first branch transaction may be registered by the resource manager with the transaction coordinator, and allocated to the first transaction chain. The transaction mode corresponding to the first branch transaction is SAGA mode. Then, the second branch transaction can be registered with the transaction coordinator through the resource manager, if the transaction mode corresponding to the second branch transaction is TCC mode, an association relation table containing the corresponding relation between the first global transaction identifier and the second global transaction identifier can be established, and the second branch transaction is distributed to a second transaction chain.

And registering the third branch transaction with the transaction coordinator through the resource manager, and judging whether the first global transaction identifier is associated with the second global transaction identifier or not if the transaction mode corresponding to the current branch transaction is the TCC mode. If yes, the current branch transaction can be distributed to a second transaction chain corresponding to the second global transaction identification.

S270, acquiring transaction processing requests sent by the transaction managers according to the states of the resource managers.

S280, determining a transaction chain processing sequence according to the transaction mode of the branch transaction corresponding to each transaction chain; and processing the distributed transactions in each transaction chain according to the transaction chain processing sequence and the transaction processing request.

In this embodiment, the transaction chain processing order may be that all the branch transactions in the first transaction chain are processed, then all the branch transactions in the second transaction chain are processed, or all the branch transactions in the first transaction chain are processed after all the branch transactions in the second transaction chain are processed.

In this step, specifically, if the transaction mode of the first transaction chain corresponding to the branch transaction is the SAGA mode and the transaction mode of the first transaction chain corresponding to the branch transaction is the TCC mode, it may be determined that the transaction chain processing order is that all the branch transactions in the first transaction chain are processed, and then all the branch transactions in the second transaction chain are processed. When the transaction request is a global transaction commit, all branch transactions in the first transaction chain may be committed first, and then all branch transactions in the second transaction chain may be committed. When the transaction request is global transaction retraction, all the branch transactions in the first transaction chain may be retracted after all the branch transactions in the second transaction chain are retracted.

Taking the scenario of TCC transaction nest invoking SAGA transactions as an example, assuming that the distributed transaction includes a retail multi-loan branch transaction (TCC mode) and a cash box branch transaction (SAGA mode), a global transaction in TCC mode may be first started, and a first branch transaction in TCC mode may be allocated to a first transaction chain. And when the second branch transaction called by the first branch transaction is in the SAGA mode, inquiring whether a second global transaction identifier exists or not through the association relation table, wherein the second global transaction identifier corresponds to the SAGA mode. If there is a second global transaction identification (i.e., there is a second transaction chain for SAGA mode), then a second branch transaction may be assigned to the second transaction chain.

In an optional implementation manner of the embodiment of the present invention, when the transaction processing request is global transaction retraction, the transaction mode of the first transaction chain corresponding to the branch transaction is TCC mode, and the transaction mode of the first transaction chain corresponding to the branch transaction is SAGA mode, if any branch transaction in the second transaction chain fails to retract, a retraction failure prompt is sent to the user. Then, all the branch transactions in the second transaction chain are manually reprocessed, and according to the reprocessing result, all the branch transactions in the second transaction chain are processed. The reprocessing result may be that all the branch transactions in the second transaction chain are cancelled successfully or all the branch transactions in the second transaction chain are committed successfully. If all the branch transactions in the second transaction chain are revoked successfully, all the branch transactions in the second transaction chain may be revoked. If all of the branch transactions in the second transaction chain commit successfully, all of the branch transactions in the second transaction chain may be committed.

The advantage of this arrangement is that by processing all the branch transactions in the second transaction chain according to the reprocessing result of all the branch transactions in the second transaction chain, it is possible to achieve synergistic association of the first transaction chain and the second transaction chain with either all success or all failure, ensuring the fund security and consistency of the distributed transactions.

According to the technical scheme of the embodiment, a first global transaction identifier is generated according to a global transaction starting request; acquiring service characteristics corresponding to each branch transaction registered by a resource manager, and determining a transaction mode corresponding to each branch transaction according to the service characteristics corresponding to each branch transaction; generating a second global transaction identifier according to the transaction mode corresponding to each branch transaction; judging whether a transaction mode corresponding to the current branch transaction is a first branch transaction or not; if yes, distributing the current branch transaction to a first transaction chain; if not, if the transaction mode corresponding to the current branch transaction is the same as the transaction mode corresponding to the first branch transaction, distributing the current branch transaction to a first transaction chain; if the transaction mode corresponding to the current branch transaction is different from the transaction mode corresponding to the first branch transaction, distributing the current branch transaction to a second transaction chain; acquiring a transaction request sent by a transaction manager according to the state of each resource manager; determining a transaction chain processing sequence according to the transaction mode of the branch transaction corresponding to each transaction chain; according to the transaction chain processing sequence and the transaction processing request, the technical means of processing the distributed transactions in each transaction chain is achieved, the problem that SAGA mode transaction and TCC mode transaction can only be manually submitted by a teller when the conventional Seata only supports single-mode distributed transactions, so that the SAGA mode branch transaction and TCC mode branch transaction can be manually submitted respectively in the transaction processing chain is solved, the transaction mode of the branch transaction is supported by a developer, the developer only needs to determine the transaction mode of the branch transaction according to the service characteristics of the branch transaction, whether the branch transactions in different transaction modes can be mutually called is not considered, and the cost and complexity of processing the distributed transactions are reduced.

In the technical scheme of the disclosure, the related processes of collecting, storing, using, processing, transmitting, providing, disclosing and the like of the personal information of the user accord with the regulations of related laws and regulations, and the public order colloquial is not violated.
