[0031] To make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0032] The distributed transaction processing method, device, electronic device and computer-readable storage medium provided by the present application are intended to solve the above technical problems in the prior art.

[0033] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. These specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0034] An embodiment of the present application provides a method for distributed transaction processing, as Figure 1As shown in the figure, the method includes:

[0035] Step S101: When the distributed transaction is in an open state, call the stored preset proxy class; where the preset proxy class includes processing methods corresponding to transaction requests of different transaction types respectively.

[0036] First of all, it should be noted that a distributed transaction means that the participants of the transaction, the servers supporting the transaction, the resource servers, and the transaction manager are respectively located on different nodes of different distributed systems. The distributed transaction processing method provided in the embodiments of the present application is applied to the transaction manager, such as the client of the transaction control center.

[0037] When the distributed transaction is in an open state, the stored preset proxy class can be called. Among them, the preset proxy class can be a custom data connection class, which is responsible for proxying the database connection in the local transaction, and the preset proxy class includes processing methods corresponding to transaction requests of different transaction types respectively, and can be applied in a certain stage of the distributed transaction.

[0038] It can be understood that when operating the application, there will be continuous interaction with the database. When the interaction frequency is too high, the database pressure will be too large, resulting in the application running smoothly. The corresponding data can be retrieved from the database and placed in the memory when the application starts to reduce the database pressure.

[0039] In an embodiment of the present application, the preset proxy class is stored in the memory. When the distributed transaction is in an open state, the client of the transaction control center calls the preset proxy class in the memory, and the data for the distributed transaction retrieved from the database is also stored in the memory, so that the execution operation of the distributed transaction is in the memory, reducing the interaction with the database and reducing the database pressure.

[0040] In an embodiment of the present application, transaction proxy can be implemented using javaagent, that is, it can be provided to the application integration in the form of a java jar package or other language SDK (Software Development Kit) to reduce the intrusion into the business code.

[0041] In addition, when the distributed transaction is in an open state, the transaction identifier of the distributed transaction can also be stored in the memory. It should be noted that the distributed transaction includes multiple local transactions, and the transaction identifier of the distributed transaction is also the transaction identifier of the local transaction. Similarly, the current transaction request also contains this transaction identifier.

[0042] To better understand the solution of the present application, a relationship diagram of the client of the transaction control center, the memory, and the preset proxy class is provided in the embodiments of the present application, as Figure 2 shown.

[0043] Step S102: Intercept the current transaction request and determine the current transaction type corresponding to the current transaction request.

[0044] Step S103: Determine the current processing method for the current transaction request in the preset proxy class.

[0045] Among them, the current transaction request includes requests sent by local applications, and the current transaction request type is carried in the current transaction request. The current transaction type includes strong consistency type or eventual consistency type. Correspondingly, the preset proxy class includes processing methods corresponding to transaction requests of different transaction types respectively. Therefore, when the current transaction request is intercepted and the current transaction type corresponding to the current transaction request is determined, the current processing method for the current transaction request can be determined in the preset proxy class.

[0046] It can be understood that after the transaction control center client intercepts the current transaction request, it can also notify each resource manager participating in the transaction, that is, the database, so that the database prepares the transaction. In the embodiments of the present application, since the data for the distributed transaction retrieved from the database has been saved in the memory, the transaction can be prepared in the memory. Exemplarily, the transaction log can be written, the transaction can be executed, and wait for further notification from the server.

[0047] Step S104: Receive the notification from the server and execute the current processing method based on the notification content.

[0048] It can be understood that when the transaction preparation of the current transaction request is completed or failed in the memory, information on whether it is ready can be sent to the server. The server sends a notification instruction to the control center client according to the information on whether it is ready. It can also be that the control center client listens for the notification instruction sent by the server, and the control center client executes the processing method for the intercepted transaction request according to the notification content.

[0049] In the present application, in the open state of the distributed transaction, the stored preset proxy class is called, and the data snapshot in the distributed transaction can be automatically recorded by proxying the connections in the distributed transaction; and by using the processing methods corresponding to transaction requests of different transaction types included in the preset proxy class to determine the current processing method for the intercepted current transaction request, the processing efficiency of the distributed transaction can be improved, and the intrusion into the business code can be reduced; then receive the notification from the server and execute the current processing method based on the notification. Completing the current transaction request through the asynchronous message notification method can improve the performance of the business system.

[0050] In an embodiment of the present application, the transaction type in the current transaction request is the strong consistency type, the preset proxy class is stored in the memory, and the processing methods for the current transaction request in the preset proxy class include a first commit method and a first rollback method;

[0051] The execution of the current processing method includes:

[0052] If there is no connection corresponding to the current transaction request in the memory, call the first interface of the server to submit the first distributed transaction;

[0053] And / or

[0054] Execute a rollback operation and delete the preset proxy class in the memory.

[0055] It can be understood that the transaction type of the current transaction request is a strong consistency type. For the purpose of ensuring strong consistency, for the execution of the first submission method, the submission operation for the current transaction request does not need to be executed in the preset proxy class, and it can be confirmed in the memory whether there is a connection corresponding to the current transaction request according to the identifier of the current transaction request. If there is no connection corresponding to the current transaction request in the memory, the first interface of the server, such as the submission interface, can be called to submit a distributed transaction to ensure the integrity of the distributed transaction.

[0056] First of all, it should be noted that the rollback command returns the database state to the state at the last commit. For the execution of the first rollback method, the rollback operation for the current transaction request can be executed in the preset proxy class. It can be understood that if the rollback operation is executed, it indicates that the processing method for the current transaction request is incorrect. At this time, the preset proxy class or the data corresponding to the current transaction request can be deleted in the memory to ensure the accuracy of the distributed transaction.

[0057] In an embodiment of the present application, as Figure 3 shown, receiving the notification from the server and executing the current processing method based on the notification content further includes:

[0058] Step S301: Based on the identifier of the current transaction request, obtain at least two preset proxy classes related to the current transaction request from the memory.

[0059] Step S302: Execute the current processing method for the current transaction request in the preset proxy class determined according to the transaction type corresponding to the current transaction request.

[0060] Step S303: Disconnect the preset proxy class from the database, clear the data related to the current transaction request in the memory based on the identifier of the current transaction request, and send the notification completion information to the server.

[0061] Among them, the notification content of the service includes a submission notification and a rollback notification. After receiving the notification from the server for the current transaction request or monitoring the notification from the server for the current transaction request, the transaction control center client can obtain multiple preset proxy classes related to the current transaction request in memory according to the identifier of the current transaction request. It can be understood that the current transaction request is a request in a node of a distributed transaction. In the actual application process, multiple nodes can jointly complete the entire distributed transaction. For the purpose of achieving strong consistency, after receiving the notification from the server, multiple preset proxy classes related to the current transaction request can be obtained in memory, and the first submission method or the first rollback method corresponding to the current transaction type is executed for all of them.

[0062] After executing the processing method in the preset proxy class, in order to enable the database to serve other distributed transactions, the connection between the preset proxy class and the database can be disconnected; and the data related to the current transaction in memory can be cleared according to the identifier of the current transaction request to reduce the resource pressure on the memory; finally, the information indicating that the submission is completed or the rollback is completed can be sent to the server, so that the server can transfer the ended transaction data to other databases, such as a relational database, as a basis for recovery in case of a failure.

[0063] In an embodiment of the present application, when the transaction type in the current transaction request is the eventually consistent type, the distributed transaction processing method further includes:

[0064] (1) The intercepted current transaction request includes a data manipulation language operation, and the execution result corresponding to the operation statement in the data manipulation language is obtained.

[0065] Among them, when the intercepted current transaction request includes a data manipulation language operation, the operation corresponding to the data manipulation language can be directly executed in the preset proxy class. Specifically, since the preset proxy class is connected to the database, the preset proxy class can be used to interact with the database, execute the operation statement in the data manipulation language, and obtain the execution result.

[0066] In an embodiment of the present application, obtaining the execution result corresponding to the operation statement in the data manipulation language includes:

[0067] If the operation statement is a delete or update statement, the delete or update statement is converted into a select statement, and a result set is obtained by querying in the preset proxy class.

[0068] If the operation statement is an insert statement, the table name and the primary key field name are extracted from the structured query language, and the primary key field value is extracted from the variable binding value. Among them, extracting the primary key field name includes querying and extracting from the database system table.

[0069] (2) Add a distributed lock to the current transaction request based on the execution result so that the execution result is temporarily stored in the data snapshot variable of the preset proxy class.

[0070] The name of the distributed lock may be library name_table name_primary key field name_primary key field value. It is understandable that, since the transaction type of the current transaction request is an eventually consistent type, the intermediate execution result may be temporarily stored first.

[0071] In one embodiment of the present application, the transaction type in the current transaction request is an eventually consistent type, the preset proxy class is stored in the memory, and the processing method for the current transaction request in the preset proxy class includes a second commit method and a second rollback method;

[0072] Execution of the current processing method includes:

[0073] Save the data snapshot of the current transaction request, perform the commit operation, and delete the preset proxy class in memory;

[0074] and / or,

[0075] Execute the rollback operation, clean up the data snapshot variables in the preset proxy class, and if there is no connection with the current transaction request in the memory, call the second interface of the server to roll back the second distributed transaction.

[0076] It can be understood that the transaction type of the current transaction request is an eventually consistent type. In order to ensure the purpose of eventual consistency, for executing the second submission method, for example, the snapshot interface can be called to save the data snapshot of the current transaction request, and the data snapshot variable can be cleared, and then the submission operation is performed in the preset proxy class, and the preset proxy class is deleted in the memory.

[0077] For executing the second rollback method, a rollback operation for the current transaction request can be executed in the preset proxy class, and the data snapshot variable can be cleared; then, according to the identifier of the current transaction request, it is confirmed in the memory whether there is a connection with the current transaction request. If there is no connection with the current transaction request in the memory, the second interface of the server, such as the rollback interface, can be called to roll back a distributed transaction.

[0078] In one embodiment of the present application, Figure 4 As shown, receiving a notification from the server, executing the current processing method based on the notification content, and further comprising:

[0079] Step S401: If the notification content is a rollback notification, extract a data snapshot from the notification content, and obtain a data source name from the data snapshot.

[0080] Step S402: connecting to the database based on the data source name, and performing a rollback operation based on the data snapshot in the database.

[0081] Step S403: Disconnect from the database and send the rollback completion information to the server.

[0082] If a rollback notification from the server is received, the rollback indicates that the current stage operation has failed and the database state returns to the state of the last commit. Therefore, the data committed last time can be obtained from the data snapshot. Specifically, when the transaction request of the current transaction is prepared or fails in memory, information on whether it is ready can be sent to the server. Based on the information on whether it is ready, the server sends a notification instruction to the control center client. Therefore, the information of the data snapshot can be extracted from the notification content.

[0083] It can be understood that after obtaining the data snapshot information, the name of the data source can be obtained from the data snapshot information, and then the database can be reconnected based on the data source name, and a rollback operation based on the data snapshot can be executed in the database. Among them, in the eventually consistent type, compared with providing a corresponding rollback interface in the existing business system, in the embodiment of the present application, by executing the rollback operation in the database, there is no need for the original business system to provide an interface, reducing the intrusion into the original business code.

[0084] After the rollback operation is completed, disconnect from the database, release resources, and send the rollback completion information to the server, so that the server can transfer the ended transaction data to other databases, such as a relational database, as a basis for recovery after a failure.

[0085] In an embodiment of the present application, the distributed transaction processing method further includes:

[0086] If a distributed transaction fails, send the exception information to the server, where the exception information includes the cause of the exception and the exception code.

[0087] It can be understood that the transaction center client can also monitor the running state of the distributed transaction. When the distributed transaction fails, the cause of the failure and the exception code can be sent to the server to solve the exception more timely and ensure the normal operation of the distributed transaction.

[0088] The embodiment of the present application provides a distributed transaction processing device, as Figure 5 shown. The distributed transaction processing device 50 may include: a call module 501, an interception module 502, a determination module 503, and an execution module 504, where

[0089] The call module 501 is configured to call a stored preset proxy class in the open state of the distributed transaction; where the preset proxy class includes processing methods corresponding to transaction requests of different transaction types.

[0090] First of all, it should be noted that a distributed transaction means that the participants of the transaction, the servers supporting the transaction, the resource servers, and the transaction manager are respectively located on different nodes of different distributed systems. The distributed transaction processing method provided in the embodiments of the present application is applied to the transaction manager, such as the client of the transaction control center.

[0091] In the state where the distributed transaction is enabled, a stored preset proxy class can be called. Among them, the preset proxy class can be a custom data connection class, which is responsible for proxying the database connection in the local transaction, and the preset proxy class includes processing methods corresponding to transaction requests of different transaction types, which can be applied in a certain stage of the fractional transaction.

[0092] It can be understood that when operating on the application, it will interact with the database continuously. When the interaction frequency is too high, the database pressure will be too large, resulting in the application running smoothly. The corresponding data can be retrieved from the database and placed in the memory when the application starts to reduce the database pressure. In an embodiment of the present application, the preset proxy class is stored in the memory. In the state where the distributed transaction is enabled, the client of the transaction control center calls the preset proxy class in the memory, and the data for the distributed transaction retrieved from the database is also saved in the memory, so that the execution operation of the distributed transaction is in the memory, reducing the interaction with the database and reducing the database pressure.

[0093] In an embodiment of the present application, it can be implemented using javaagent to achieve transaction proxy, that is, it can be provided to the application integration in the form of a java jar package or other language SDK (Software Development Kit), so as to reduce the intrusion into the business code.

[0094] In addition, in the state where the distributed transaction is enabled, the transaction identifier of the distributed transaction can also be saved in the memory. It should be noted that the distributed transaction includes multiple local transactions, and the transaction identifier of the distributed transaction is also the transaction identifier of the local transaction. Similarly, the current transaction request also contains this transaction identifier.

[0095] The interception module 502 is used to intercept the current transaction request and determine the current transaction type corresponding to the current transaction request.

[0096] The determination module 503 is used to determine the current processing method for the current transaction request in the preset proxy class.

[0097] Among them, the current transaction request includes requests sent by local applications, and the current transaction request carries the current transaction request type, where the current transaction type includes strong consistency type or eventual consistency type. Correspondingly, the preset proxy class includes processing methods respectively corresponding to transaction requests of different transaction types. Therefore, when intercepting the current transaction request and determining the current transaction type corresponding to the current transaction request, the current processing method for the current transaction request can be determined in the preset proxy class.

[0098] It can be understood that after the transaction control center client intercepts the current transaction request, it can also notify each resource manager participating in the transaction, that is, the database, so that the database prepares the transaction. In the embodiments of the present application, since the data for the distributed transaction retrieved from the database has been saved in memory, the transaction can be prepared in memory. Exemplarily, the transaction log can be written, the transaction can be executed, and wait for further notification from the server.

[0099] The execution module 504 is configured to receive the notification from the server and execute the current processing method based on the notification content.

[0100] It can be understood that when the transaction preparation of the current transaction request is completed or fails in memory, information on whether it is ready can be sent to the server. The server sends a notification instruction to the control center client based on the information on whether it is ready. Alternatively, the control center client can listen for the notification instruction sent by the server, and the control center client executes the processing method for the intercepted transaction request according to the notification content.

[0101] In the present application, in the open state of the distributed transaction, the stored preset proxy class is called, and the data snapshot in the distributed transaction can be automatically recorded by proxying the connections in the distributed transaction; and by using the processing methods respectively corresponding to transaction requests of different transaction types included in the preset proxy class to determine the current processing method for the intercepted current transaction request, the processing efficiency of the distributed transaction can be improved, and the transaction proxy is implemented using javaagent to reduce the intrusion into the business code; then receive the notification from the server and execute the current processing method based on the notification. Completing the current transaction request through the asynchronous message notification method can improve the performance of the business system.

[0102] In an embodiment of the present application, the transaction type in the current transaction request is the strong consistency type, the preset proxy class is stored in memory, and the processing methods for the current transaction request in the preset proxy class include a first commit method and a first rollback method;

[0103] The execution module includes:

[0104] The first submission sub-module is used to call the first interface of the server to submit the first distributed transaction if there is no connection in the memory that matches the current transaction request.

[0105] And / or

[0106] The first rollback sub-module is used to perform a rollback operation and delete a preset proxy class in the memory.

[0107] In an embodiment of the present application, the execution module further includes:

[0108] The acquisition sub-module is used to acquire at least two preset proxy classes related to the current transaction request from the memory based on the identifier of the current transaction request.

[0109] The first execution sub-module is used to execute the current processing method for the current transaction request in the preset proxy class determined according to the transaction type corresponding to the current transaction request.

[0110] The first sending sub-module is used to disconnect the preset proxy class from the database, clear the data related to the current transaction request in the memory based on the identifier of the current transaction request, and send a notification completion message to the server.

[0111] In an embodiment of the present application, when the transaction type in the current transaction request is the eventually consistent type, the distributed transaction processing device further includes:

[0112] The acquisition module is used to intercept the current transaction request that includes a data manipulation language operation, and acquire the execution result corresponding to the operation statement in the data manipulation language.

[0113] The addition module is used to add a distributed lock to the transaction request according to the execution result, so that the execution result is temporarily stored in the data snapshot variable of the preset proxy class.

[0114] In an embodiment of the present application, the acquisition module includes:

[0115] The query sub-module is used to convert the delete or update statement into a select statement if the operation statement is a delete or update statement, and perform a query in the preset proxy class to obtain a result set.

[0116] The first extraction sub-module is used to extract the table name and the primary key field name from the structured query language and extract the primary key field value from the variable binding value if the operation statement is an insert statement. Among them, extracting the primary key field name includes querying and extracting from the database system table.

[0117] In an embodiment of the present application, when the transaction type in the current transaction request is the eventually consistent type, the preset proxy class is stored in the memory, and the processing methods for the current transaction request in the preset proxy class include a second submission method and a second rollback method.

[0118] The execution module includes:

[0119] A second submission sub-module, configured to save a data snapshot of the current transaction request, perform a submission operation, and delete a preset proxy class in the memory;

[0120] and / or

[0121] A second rollback module, configured to perform a rollback operation, clean data snapshot variables in the preset proxy class, and if there is no connection to the current transaction request in the memory, call a second interface of the server to roll back the second distributed transaction.

[0122] In an embodiment of the present application, the execution module further includes:

[0123] A second extraction sub-module, configured to extract a data snapshot from the notification content if the notification content is a rollback notification, and obtain a data source name from the data snapshot;

[0124] A second execution sub-module, configured to connect to a database based on the data source name and perform a rollback operation based on the data snapshot in the database;

[0125] A second sending sub-module, configured to disconnect from the database and send rollback completion information to the server.
