Description

Distributed transaction processing method, system, transaction manager and terminal equipment

Technical Field

The embodiments of the present disclosure relate to the field of distributed transaction processing technologies, and in particular, to a distributed transaction processing method, a distributed transaction processing system, a transaction manager, and a terminal device.

Background

The distributed transaction means that a participant of the transaction, a server supporting the transaction, a resource manager and a transaction manager are respectively positioned on different nodes of different distributed systems. A transaction is an indivisible unit of work, and a distributed transaction typically contains multiple local transactions, each of which is either executed or not executed. For example, assuming that operation 1 on database a, operation 2 on database B, and operation 3 on database C are a distributed transaction, the distributed transaction will be executed successfully only if all three operations, i.e., operation 1, operation 2, and operation 3, are executed successfully.

Most distributed transactions generally follow a Two Phase commit protocol (2 PC). 2PC is a basic protocol of distributed transactions, one stage in 2PC is a voting stage, and all resource managers send feedback results of whether the transaction is successful to the transaction manager; the two phases in 2PC are execution phases, and the transaction manager executes corresponding operations according to the feedback results of all resource managers. If the feedback results of all the resource managers are received successfully, all the resource managers are informed to submit on all the branches in a pace-consistent manner; and if the feedback result received from one of all the resource managers is failure, all the resource managers are notified to roll back on all the branches. As can be seen, the one and two phases are performed serially, and only after the two phases have ended is the execution of the distributed transaction completed.

for example, as shown in fig. 1, firstly, a participant of a transaction initiates a transaction, a transaction manager coordinates a resource manager in two stages, namely, in one stage, the transaction manager sends a preparation operation request to all resource managers, and all resource managers return response results according to the preparation operation request, ② 2 in two stages, the transaction manager sends an execution operation request to all resource managers according to the response results returned by all resource managers in one stage, and thirdly, all resource managers execute corresponding operations according to the execution operation request sent by the two-stage service manager, and finally, after the execution is completed from 0 to ④, the whole distributed transaction is executed.

In summary, the existing distributed transaction processing needs to execute one stage and two stages for each resource manager, so that the distributed transaction processing has more execution links and longer total time consumption.

Detailed Description

In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the present specification.

Embodiments of the present specification provide a distributed transaction processing method and terminal device, so as to solve the problems in the prior art that there are many execution links of distributed transaction processing and the total time consumption is long. The embodiments of the present specification provide a distributed transaction processing method, and an execution subject of the method may be, but is not limited to, a transaction manager of a distributed transaction or an apparatus or system capable of being configured to execute the method provided by the embodiments of the present specification.

For convenience of description, the following description will be made of an embodiment of the method, taking an execution subject of the method as a transaction manager capable of executing the method. It is to be understood that the execution of the method by the transaction manager is merely an exemplary illustration and should not be construed as a limitation of the method.

Fig. 3 is a flowchart of a distributed transaction processing method provided in an embodiment of the present specification, where the method of fig. 3 may be executed by a transaction manager, and as shown in fig. 3, the method may include:

step 310, responding to the request operation of the distributed transaction, respectively sending preparation operation requests of sub-transactions of the distributed transaction to a plurality of resource managers.

The prepare operation request requests validation of the execution results of the resources of the corresponding sub-transaction.

And 320, executing the transaction operation corresponding to the response result on the distributed transaction in an asynchronous mode based on the response result of the preparation operation request of the plurality of resource managers on the sub-transaction of the distributed transaction.

It should be understood that after the transaction manager obtains the response result of the preparation operation request of the multiple resource managers to the sub-transaction of the distributed transaction, the transaction manager executes the transaction operation corresponding to the response result to the distributed transaction in an asynchronous manner.

In other words, the transaction manager's processing of the distributed transaction is completed after the transaction manager obtains the results of the responses of the multiple resource managers to the prepare operation requests of the sub-transactions of the distributed transaction.

The response result may be a preparation success or a preparation failure; alternatively, the response result may be an execution success or an execution failure.

Executing the transaction operation corresponding to the response result on the distributed transaction in an asynchronous manner, which may specifically be:

the transaction manager reports response results of the preparation operation requests of the resource managers for the sub-transactions of the distributed transactions to other equipment, such as a server, and the other equipment executes the transaction operation corresponding to the response result according to the response result; or,

and the transaction manager distributes response results of the preparation operation requests of the resource managers to the sub-transactions of the distributed transactions to a plurality of synchronous threads in the thread pool, and the plurality of synchronous threads execute the transaction operation corresponding to the response result according to the response result.

Optionally, as an embodiment, the distributed transaction processing method provided in this specification embodiment may further include:

receiving a transaction starting request sent by a client, and allocating a plurality of sub-transactions divided by a distributed transaction corresponding to the transaction starting request to a plurality of resource managers for processing a preparation operation.

For example, assuming "account a transfers to account B" as a distributed transaction, then a write operation needs to be performed on three resource managers (i.e., the distributed transaction can be divided into three sub-transactions), respectively:

operation 1, deducting a preset amount from the account A on the resource manager 1;

operation 2, adding corresponding amount to the account B on the resource manager 2;

and operation 3, performing transfer aggregation on the resource manager 3.

If the response results of the three resource managers after the preparation operation processing are all successful, determining to submit the distributed transaction; and if at least one response result in response results after the three resource managers perform the preparation operation processing is that the preparation is failed, determining to perform rollback operation on the distributed transaction.

In practical applications, the implementation of the method of the present specification is described in detail, for example, along with the above examples:

a user initiates an operation of transferring accounts from an account A to an account B at a client side, and registers a distributed transaction to a transaction manager according to the operation performed by the user; the transaction manager will assign a transaction identification ID to the distributed transaction. The "account a transfers to account B" requires a write operation on three resource managers, that is, the distributed transaction may be divided into three sub-transactions:

and operation 3, performing transfer aggregation on the resource manager 3.

And after the sub-transaction processing is completed, the transaction manager executes the transaction operation corresponding to the response result on the distributed transaction in an asynchronous mode based on the response results of all the sub-transactions.

If so, after the transaction manager reports the response results of all the sub-transactions to the standby database, the server side serves as a coordinator to query the response results of all the sub-transactions in the standby database, and determines to initiate submission or rollback of the distributed transaction according to the queried response results of all the sub-transactions; or,

and the transaction manager distributes the sub-transactions respectively corresponding to the response results to a plurality of synchronous threads in the thread pool according to a preset distribution rule, and the synchronous threads determine to initiate the submission or rollback of the distributed transaction based on the response results.

Optionally, as an embodiment, the step 120 may be specifically implemented as:

distributing sub-transactions respectively corresponding to the plurality of response results to a plurality of synchronous threads in a thread pool according to a preset distribution rule, wherein the thread pool is pre-configured with the plurality of synchronous threads;

and the synchronous threads in the thread pool are used for executing the transaction operation corresponding to the response result on the distributed transaction in an asynchronous mode.

In this application, a thread pool needs to be established in advance, and the synchronous threads in the thread pool in this embodiment may be: a thread that calls run method execution is required.

For example, 10 synchronous threads are configured in advance in the thread pool, the 10 thread synchronizations need to be executed by a run method, and the 10 synchronous threads executed by the run method can be executed in the main thread during execution, so that the ending time of the synchronous thread executing the task can be perceived by the main thread.

The thread pool can directly or indirectly extend from the threadpoolsexecutor provided by JDK (Java Development Kit, software Development Kit in Java language). The thread pool (doimmediateltylthreadthreadpottaskeexecutor) in this embodiment is different from the thread pool in the prior art, and the synchronous threads of the thread pool in this embodiment all call run methods to be executed, so that the synchronous threads can be synchronously executed in the called main thread.

The sub-transactions respectively corresponding to the multiple response results are allocated to multiple synchronous threads in a thread pool according to a preset allocation rule, and the multiple synchronous threads are preconfigured in the thread pool, and the specific implementation may include:

step A1: and establishing a task queue for the thread pool.

Firstly, a task queue is established for the created thread pool, and the task queue can store the tasks distributed to the synchronous threads in the thread pool according to the sequence.

Step A2: and adding the plurality of sub-transactions into the task queue according to the users triggering the plurality of sub-transactions respectively.

In this embodiment, the plurality of sub-transactions may be added to the task queue according to different users who trigger the sub-transactions.

For example, for the buffering and account-repairing service in practical application, there are four users that trigger 7 tasks of buffering and account-repairing.

Specifically, as shown in table 1:

TABLE 1

User tasks	id
		A	1
A	2
		A	3
B	4
		B	5
C	6
		D	7

Then, the task queue may add the three sub-transactions of user a, then add the two sub-transactions of user B, and then add the tasks of user C and user D in sequence.

Step A3: and respectively distributing the sub-transactions in the task queue to a plurality of synchronous threads in a thread pool, wherein each user corresponds to one synchronous thread.

And then, the sub-transactions in the task queue are respectively allocated to a plurality of synchronous threads in the thread pool, for example, the sub-transaction of each user is correspondingly allocated to one synchronous thread. Then, referring to Table 1, three sub-transactions for user A may be assigned to the first synchronous thread in the thread pool, two sub-transactions for user B may be assigned to the second synchronous thread in the thread pool, and so on.

Certainly, in practical application, the method is not limited to allocating the threads to the tasks by taking the user as the dimension, and may also allocate one synchronization thread to each sub-transaction by taking the sub-transactions as the dimension, and of course, other allocation manners may also be adopted.

As shown in fig. 4, in the embodiment of the present specification, in the two-phase transaction manager, the sub-transactions corresponding to the multiple response results returned by all the resource managers in the one phase are respectively allocated to the multiple synchronous threads in the thread pool according to the preset allocation rule, and the multiple synchronous threads in the thread pool execute the transaction operation corresponding to the response result on the distributed transaction in an asynchronous manner, so that the transaction manager reduces the total execution link of the distributed transaction, and the total consumption time is changed to the sum of a + b + c + g, thereby effectively reducing the execution loss of the distributed transaction.

Optionally, as an embodiment, the step 120 may be specifically implemented as:

and storing the response result and the corresponding relation between the response result and the transaction operation request corresponding to the response result in a standby database, so that other equipment asynchronously executes the transaction operation corresponding to the response result based on the response result inquired in the standby database.

The backup database may be a database of other devices, or may be an independent database with respect to other devices, and the embodiments of the present specification are not particularly limited.

For example, after the transaction manager reports the response results of all the sub-transactions to the standby database, the server side, as a coordinator, queries the response result of each sub-transaction in the standby database, and determines to initiate submission or rollback of the distributed transaction according to the queried response result of each sub-transaction, specifically, if the response results of all the sub-transactions of the distributed transaction are successfully prepared, it is determined to submit the distributed transaction, and if at least one response result of all the sub-transactions is a sub-transaction that fails to be prepared, it is determined to rollback the distributed transaction. Specifically, after determining to commit or rollback the distributed transaction, the server sends a commit command or a rollback command to each of the sub-transactions to initiate a commit or rollback of the global transaction. Therefore, the committing of the distributed transaction can be executed according to the received command which is sent by the server and used for committing the distributed transaction; or according to a received command of rolling back the distributed transaction sent by the server, the roll back of the distributed transaction is executed. That is, if a command to commit the distributed transaction is received, which is sent by the server, the commit of the distributed transaction is performed; and if the received command sent by the server for rolling back the distributed transaction is received, the roll back of the distributed transaction is executed.

In the embodiment of the present specification, the response result and the corresponding relationship between the response result and the transaction operation request corresponding to the response result are stored in the standby database, and the other device executes the transaction operation corresponding to the response result based on the response result queried in the standby database, so that the purpose that the transaction operation corresponding to the response result is executed in an asynchronous manner is achieved, the execution link of the distributed transaction processing is reduced, and the execution loss of the distributed transaction is reduced.
