Description

Distributed transaction processing method, device, system, computer equipment and storage medium

Technical Field

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

Background

The current software development of the server needs to use the storage function of the database, for example, the Mysql database already realizes ACID (ACID is four principles of normal execution of database transactions, which respectively refer to atomicity, consistency, independence and durability), so that the requirements of daily business can be met. However, when the database system is a distributed system, since there are multiple Mysql databases, the multiple Mysql databases cannot meet the ACID characteristic, which results in no way to perform an atomic operation between the multiple databases, and causes a problem of distributed transactions. For distributed transaction problems, conventional techniques typically employ XA transactions or TCC transactions to resolve.

XA transaction refers to processing the transaction by adopting an XA protocol, wherein the XA protocol is proposed by Tuxedo and is given to an X/Open organization to serve as an interface standard of a resource manager (database) and a transaction manager. Currently, each large database vendor, oracle, informix, DB and Sybase, etc., provides support for XA. Referring to fig. 1, fig. 1 is a schematic diagram of XA transaction processing in the conventional technology, and as shown in fig. 1, the XA protocol uses a two-phase commit mode to manage distributed transactions, and two-phase commit is performed by a transaction manager service a and a transaction manager service B to manage distributed transactions. The XA interface provides a standard interface for communication between the resource manager and the transaction manager. The XA protocol includes two sets of functions, XA-headed and ax-headed. The following functions enable the transaction manager to perform operations on the resource manager: 1) xa_open, xa_close function for establishing and closing connections with resource manager; 2) xa_start, xa_end function for starting and ending a local transaction; 3) xa_preparation, xa_commit, xa_rollback functions for pre-committing, and rolling back a local transaction; 4) An xa_recovery function to rollback a transaction that has been pre-committed; 5) The function of ax_start allows the resource manager to dynamically register in the transaction manager and operate on XID (TRANSACTIONIDS); 6) The ax_reg, ax_unreg function allows a resource manager to dynamically register or de-register in one TMS (TRANSACTIONMANAGERSERVER). TCC transactions, which are distributed transactions handled by TCC services, are composed of Try/Confirm/Cancel services, which when executed, access a Resource Manager (RM) to access data, and these access operations must participate in RM local transactions to make the data changed by either all Commit or all Rollback.

The TCC transaction is very highly coupled with traffic, resulting in additional system complexity, due to the poor performance caused by the long transaction time of XA transactions. Therefore, in the conventional technology, the XA transaction and the TCC transaction have serious problem of poor performance, and the processing performance for the distributed transaction is low.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It should be understood that the terms "comprises" and "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

In the embodiment of the invention, the distributed system for processing the distributed transaction comprises a transaction coordinator and a plurality of server ends, wherein the whole transaction is divided into a plurality of segmented transactions in advance, and the plurality of server ends comprise an initiating end corresponding to a transaction initiator and a plurality of processing ends for processing different segmented transactions. Referring to fig. 2, fig. 2 is a flow chart of a distributed transaction processing method applied to an initiator according to an embodiment of the invention. As shown in fig. 2, the method is applied to the originating terminal, and includes the following steps S201 to S207:

S201, receiving a service request of a client.

S202, according to the service request, a transaction opening instruction of a transaction corresponding to the service request is sent to the transaction coordinator side.

Wherein, the Transaction, english is Transaction, refers to that all operations related to the activity corresponding to one service request are incorporated into one indistinct execution unit, and the Transaction consists of all operations executed between the Transaction start (Begin Transaction) and the Transaction End (End Transaction).

Specifically, in order to support processing of mass data, the background server side avoids performance bottleneck of a single server, and the server side generally adopts a distributed system. In the embodiment of the invention, the whole transaction corresponding to the service request is divided into a plurality of segmented transactions in advance, and the distributed system comprises an initiating terminal corresponding to a transaction initiator, a plurality of processing terminals for processing different segmented transactions and a transaction coordinator terminal. Because the server side generally adopts a distributed system to process the service request, when a user puts forward the service request to the server side through the client side, the initiating side receives the service request of the client side, opens a transaction corresponding to the service request according to the service request, and sends a transaction opening instruction of the transaction corresponding to the service request to the transaction coordinator side. For example, when a user makes shopping through a smart phone, a transaction corresponding to a service request for creating a shopping order of the user is divided into two subsection transactions in advance, when the user makes shopping through the smart phone and needs to create the shopping order, the smart phone is used for providing a service request for creating the shopping order to a background server, an initiating terminal corresponding to a transaction initiator corresponding to the shopping order is created in a distributed system of the background, the service request for creating the shopping order of a client is received, and a transaction opening instruction corresponding to a transaction for opening the creating the shopping order is sent to the transaction coordinator terminal according to the service request.

S203, receiving a preset transaction identifier corresponding to the transaction returned by the transaction coordinator, wherein the preset transaction identifier is distributed by the transaction coordinator according to the transaction starting instruction.

Specifically, after receiving a transaction opening instruction, the transaction coordinator allocates a preset transaction identifier to the transaction according to the transaction opening instruction, where the preset transaction identifier corresponds to the transaction one by one and is used for uniquely describing the transaction, and the preset transaction identifier may be a serial number or a unique code configured according to a preset coding mode, so that the transaction can be identified through the preset transaction identifier. And the transaction coordinator returns the preset transaction identifier to the initiating terminal, and the initiating terminal receives the preset transaction identifier corresponding to the transaction returned by the transaction coordinator.

S204, sending processing instructions corresponding to each segmented transaction to the processing end according to a preset sequence, wherein the processing instructions carry the preset transaction identifiers so that the processing end processes the segmented transaction to obtain segmented processing results corresponding to each segmented transaction, and returning the segmented processing results to the initiating end.

Specifically, after receiving the preset transaction identifier corresponding to the transaction returned by the transaction coordinator, the initiator may concurrently process the segmented transactions included in the transaction according to a preset sequence of the segmented transaction, for example, the initiator may send the processing instruction corresponding to each segmented transaction to the processing end corresponding to each segmented transaction in parallel, the processing of the segmented transaction needs to be sequentially performed according to a sequence, the subsequent segmented transaction is based on the processing result corresponding to the previous segmented transaction, the serial relationship among the plurality of segmented transactions is provided, the subsequent segmented transaction can be performed only if the segmented transaction arranged on the front succeeds, the segmented transaction arranged on the front fails to process the subsequent segmented transaction, the initiator may sequentially send the processing instruction corresponding to each segmented transaction to the processing end corresponding to each segmented transaction according to the sequence, each processing instruction carries the preset transaction identifier, the processing instruction is used for the processing of the segmented transaction, and the processing efficiency of each segmented transaction is improved compared with the serial transaction of the serial transaction. After each processing end receives respective processing instructions, each processing end starts processing the segmented transaction corresponding to the processing end according to the respective processing instructions to obtain segmented processing results corresponding to each segmented transaction, the segmented processing results are returned to the initiating end, the corresponding relation between the segmented transaction and the service request corresponding to the transaction is identified through the preset transaction identification, and the processing results of all the segmented transactions are integrated according to the preset transaction identification to obtain transaction processing results of the transaction, namely the processing results of the service request. After each processing end receives the processing instruction of the segmented transaction corresponding to the processing of each processing end, the processing end processes the segmented transaction of the processing end to obtain the segmented processing result corresponding to the segmented transaction of each processing end, and returns the segmented processing result to the initiating end.

S205, receiving the segmentation processing result returned by the processing end.

S206, judging whether each segmentation processing result is successful.

S207, if the segmentation processing results are successful, determining that the distributed processing of the transaction is completed.

Specifically, the initiating terminal receives a segmentation processing result corresponding to each segmentation transaction returned by each processing terminal, judges whether each processing terminal successfully processes each segmentation transaction according to each segmentation processing result, and if each segmentation processing result is successful, namely each segmentation processing result is successful, judges that each processing terminal successfully processes each segmentation transaction, and the whole transaction is successfully completed, so that the corresponding segmentation transaction is completed through different processing terminals, and the distributed processing of the whole transaction is completed.

Further, the step of completing the distributed processing of the transaction includes:

generating a transaction processing result corresponding to the transaction according to the preset transaction identifier and the segmentation processing result; and submitting the transaction processing result to the transaction coordinator end to complete the distributed processing of the transaction.

Specifically, if the initiating terminal judges that each segmented processing result is successful in processing, the successful completion of the transaction is indicated, and then a transaction processing result corresponding to the transaction is generated according to the relation between the preset transaction identifier and the segmented transaction corresponding to each segmented processing result, and the transaction processing result is submitted, so that the distributed processing of the transaction is completed, and the service request is completed.

Further, in an embodiment, after the step of determining that the distributed processing of the transaction is completed if each of the segmented processing results is successful, the method further includes:

if the segmentation processing result is that the processing is not successful, a failure prompt that the transaction processing fails is sent to the transaction coordinator, so that the transaction coordinator instructs the processing end to execute rollback action to reprocess the segmentation transaction according to the failure prompt;

and iteratively executing the step if the segmentation processing result is unsuccessful until each segmentation processing result is successful.

Specifically, if the initiating terminal judges that the segmented transaction is not successfully processed, the initiating terminal judges that the transaction is not successfully processed, the initiating terminal sends a failure prompt of the transaction processing failure to the transaction coordinator, and the transaction coordinator terminal enables the transaction coordinator terminal to instruct the processing terminal to execute a rollback action to reprocess the segmented transaction according to the failure prompt, and iteratively executes the step of if the segmented processing result is that the processing is unsuccessful until each segmented processing result is that the processing is successful, and finally, the processing of all the segmented transactions contained in the transaction is successfully completed. Further, the transaction coordinator may instruct all the processing ends involved in the transaction to perform rollback actions respectively to reprocess all the segmented transactions according to the failure prompt, so that the processing of the whole transaction has temporal continuity, and the occurrence of time interruption of the transaction processing is avoided. When a processing end is in breakdown or other machine faults, the machine faults are prompted in a warning prompt mode, so that the computer equipment is maintained through manual intervention, and each sectional transaction can be processed successfully finally, and the transaction is completed.

When the embodiment of the invention realizes distributed transaction processing, the whole transaction is divided into a plurality of segmented transactions, the initiation terminal controls the initiation management of the transaction, and the transaction coordinator terminal coordinates the processing of each segmented transaction, so that the plurality of segmented transactions are processed by different processing terminals, compared with the problems of longer transaction time and poorer performance of XA transactions in the traditional technology, the TCC mode has extremely high coupling degree with services and brings extra system complexity.

Referring to fig. 3, fig. 3 is a flow chart of a distributed transaction processing method applied to a processing end according to an embodiment of the invention. The distributed system comprises a transaction coordinator and a plurality of server terminals, wherein the whole transaction is divided into a plurality of segmented transactions in advance, the plurality of server terminals comprise initiating terminals corresponding to transaction initiators and a plurality of processing terminals for processing different segmented transactions, as shown in fig. 3, the method is applied to the processing terminals and comprises the following steps of S301-S305:

S301, receiving a processing instruction for processing the segmented transaction, which is sent by the initiating terminal, wherein the processing instruction carries a preset transaction identifier corresponding to the transaction, and the preset transaction identifier is distributed and returned to the initiating terminal by the transaction coordinator terminal when the initiating terminal starts the transaction to the transaction coordinator terminal.

Specifically, when a user puts forward a service request to a server through a client, an initiating terminal receives the service request of the client, starts a transaction corresponding to the service request according to the service request, the initiating terminal sends a transaction start instruction of the transaction corresponding to the service request to the transaction coordinator, after the transaction coordinator receives the transaction start instruction, a preset transaction identifier corresponding to the transaction is allocated according to the transaction start instruction, the transaction coordinator returns the preset transaction identifier to the initiating terminal, after the initiating terminal receives the preset transaction identifier corresponding to the transaction returned by the transaction coordinator, the initiating terminal sends the processing instruction corresponding to each segmented transaction to the processing terminal according to the serial processing relation among the segmented transactions, and the initiating terminal sequentially sends the processing instruction corresponding to each segmented transaction to the processing instruction of each segmented transaction according to the processing procedure sequence.

S302, according to the processing instruction, a segmented transaction opening instruction for opening the segmented transaction is sent to the transaction coordinator, wherein the segmented transaction opening instruction carries the preset transaction identifier.

Specifically, after receiving a processing instruction for processing the segmented transaction sent by an initiating terminal, a processing terminal starts to process the segmented transaction according to the processing instruction, and sends a segmented transaction starting instruction for starting the segmented transaction to the transaction coordinator terminal, wherein the segmented transaction starting instruction carries the preset transaction identifier.

S303, receiving a preset segmented transaction identifier corresponding to the segmented transaction returned by the transaction coordinator, wherein the preset segmented transaction identifier is distributed by the transaction coordinator according to the segmented transaction starting instruction.

Specifically, after receiving a segment transaction opening instruction sent by the processing end and used for opening and processing the segment transaction, the transaction coordinator receives a segment transaction opening instruction, and then correspondingly distributes a preset segment transaction identifier to the segment transaction according to the segment transaction opening instruction, wherein the preset segment transaction identifier is similar to the preset transaction identifier and is used for uniquely describing the segment transaction and returning the preset segment transaction identifier to the processing end, and the processing end receives the preset segment transaction identifier corresponding to the segment transaction returned by the transaction coordinator end

S304, processing the segmented transaction to obtain a segmented processing result.

Specifically, after receiving a preset segmented transaction identifier corresponding to the segmented transaction, the processing end processes the segmented transaction. For example, for a segmented transaction corresponding to a deduction process in a transaction corresponding to the creation of the shopping order, a deduction operation is performed, so as to obtain a segmented processing result of the segmented transaction. Further, the segmentation processing result comprises the preset segmentation transaction identifier. The segmentation processing result comprises the preset segmentation transaction identifier, so that each main body contained in the distributed system recognizes which transaction is the processing result corresponding to which segmentation transaction in which transaction according to the preset transaction identifier and the preset segmentation transaction identifier, and further the processing result of generating the transaction according to each segmentation processing result is obtained.

S305, returning the segmentation processing result to the initiating terminal so that the initiating terminal executes the step of receiving the segmentation processing result returned by the processing terminal in the distributed transaction processing method applied to the initiating terminal.

In the embodiment of the invention, the long transaction corresponding to the whole transaction is divided into a plurality of segmented transactions in advance according to the processing process and the processing property of the transaction, so that each segmented transaction can be processed independently, and then the initiating terminal and the transaction coordinator terminal jointly start the processing of the segmented transaction of each processing terminal to the processing terminal, so that each processing terminal completes the processing of the segmented transaction of the processing terminal, and a plurality of processing terminals jointly complete the processing of all segmented transactions contained in the whole transaction, thereby realizing the distributed processing of the long transaction, avoiding the long transaction, solving the problem of extremely high coupling degree of TCC transaction and service, improving the processing performance of computer equipment on the distributed transaction, reducing the complexity of a distributed system and the maintenance cost of the distributed system, and improving the processing efficiency of the distributed transaction.
