Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Aiming at the problem that dirty reading occurs in the existing distributed transaction processing process, the embodiment of the invention provides a distributed transaction processing method, a device, a system and electronic equipment.
To facilitate understanding of the embodiment, first, a detailed description is given below of a distributed transaction processing system provided in the embodiment of the present invention, where the system may be used to implement the distributed transaction processing function of the embodiment of the present invention.
Fig. 1 is a schematic structural diagram of a distributed transaction processing system, where the distributed transaction processing system 1 includes a central server 10, and a plurality of transaction servers 20 and storage servers 30 respectively connected to the central server 10 in communication; wherein the storage server 30 is configured with a message queue 31, which components are interconnected by a bus system 40 and/or other form of connection mechanism (not shown). It should be noted that the components and structure of the distributed transaction system 1 shown in fig. 1 are exemplary only and not limiting, and that the distributed transaction system described above may have other components and structures as desired.
The central server 10, the transaction server 20 and the storage server 30 may also be configured as intelligent terminals, or devices or apparatuses including a Central Processing Unit (CPU) or other forms of processing units with data processing capability and/or instruction execution capability to implement the functions of distributed transaction processing. It should be noted that in practical applications, the central server 10 and the storage server 30 may also be one or more, for example, different central servers and corresponding storage servers are set according to different application scenarios of distributed transactions, and the setting may be specifically performed according to practical situations.
It should be noted that, in practical applications, for the plurality of transaction servers 20, in practical applications, the transaction servers are communicatively connected to each other, and in different transactions, the transaction server may be a transaction initiator, that is, a first transaction server, and may also be a transaction participant, that is, a second transaction server, for example, the transaction server a initiates a first transaction, that is, the transaction server a is the first transaction server in the first transaction; meanwhile, for a second transaction initiated by the transaction server B, the transaction server a participates in the second transaction, that is, the transaction server a is a second transaction server in the second transaction, and therefore, the specific function of each transaction server is set according to the specific transaction processing condition, which is not described in the embodiment of the present invention.
Based on the distributed transaction processing system, an embodiment of the present invention provides a distributed transaction processing method, where an execution subject is a central server, and as shown in fig. 2, the method includes the following steps:
step S202, responding to a transaction initiating request of a first transaction server, and generating global transaction information for a transaction corresponding to the transaction initiating request;
specifically, a first transaction server is a transaction initiator in a plurality of transaction servers, and before starting a distributed transaction, when a central server monitors a transaction initiation request of the first transaction server, global transaction information is generated for a transaction corresponding to the transaction initiation request; the global transaction information comprises global transaction identification information and global transaction attribute information; the global transaction identification information may be a distributed transaction ID (Identity Document) corresponding to the transaction or other identification information for characterizing the transaction, and may be specifically set according to an actual situation; the global transaction attribute information includes attribute information to which a transaction corresponding to the transaction initiation request belongs, and various operation information included in the transaction corresponding to the transaction initiation request, so that the transaction corresponding to the transaction initiation request can be distinguished from other transactions through the global transaction information, and it can be ensured that a second transaction server participating in the transaction determines corresponding to-be-operated item information according to the global transaction information, and the setting can be specifically performed according to actual conditions. For example, as shown in fig. 3, before starting the distributed transaction, when the central server 10 monitors the transaction initiation request sent by the first transaction server 21, the global transaction information of the transaction corresponding to the transaction initiation request is generated for the first transaction server 21.
In practical application, one possible allocation manner is as follows: the central server generates global transaction information for a transaction corresponding to a transaction initiation request according to the transaction initiation request of the first transaction server, and sends the generated global transaction information to the first transaction server; another possible allocation is: the method comprises the steps that a global transaction information set is stored in a central server, wherein each piece of global transaction information in the global transaction information set is different, when the central server monitors a transaction initiation request of a first transaction server, one piece of global transaction information is selected from the global transaction information set to serve as the global transaction information of a transaction corresponding to the transaction initiation request, and the selected global transaction information is sent to the first transaction server; the specific allocation mode of the global transaction information can be set according to actual situations.
Step S204, global transaction information is distributed to a second transaction server participating in the transaction through the first transaction server, so that the second transaction server feeds back to-be-operated item information corresponding to the transaction according to the global transaction information;
after the first transaction server acquires the global transaction information, the global transaction information is distributed to all second transaction servers participating in the transaction, so that the second transaction servers feed back to-be-operated item information corresponding to the transaction according to the global transaction information, wherein the second transaction servers can also be called transaction participants. After receiving the global transaction information, the second transaction server determines a corresponding local transaction according to the global transaction information, that is, in the transaction corresponding to the transaction initiation request, a distributed sub-transaction corresponding to the second transaction server, and operation information corresponding to the local transaction, such as an SQL (Structured Query Language) set for operation, and combines the second transaction and the corresponding operation information into to-be-operated item information corresponding to the second transaction server.
Therefore, the central server can obtain the local transaction and the corresponding operation information corresponding to each second transaction server in the transaction according to the information of the to-be-operated items fed back by each second transaction server. For example, as shown in fig. 3, the first transaction server 21 distributes the global transaction information to the second transaction server 22 participating in the transaction, so that the second transaction server 22 feeds back the corresponding to-be-operated item information to the central server 10; it should be noted that, only one second transaction server 22 is shown here, and the number of the second transaction servers participating in the transaction in particular may be set according to practical situations.
Step S206, storing the to-be-operated item information corresponding to the global transaction information to a storage server;
specifically, as shown in fig. 3, the central server 10 stores the to-be-operated item information corresponding to the global transaction information fed back by the second transaction server 22 in the message queue 31 according to the locked state; in the message queue, each to-be-operated item information carries corresponding global transaction information or global transaction identification information of the global transaction information, and is distinguished through the global transaction identification information; the locking state can also be called a half message state, that is, in the sending process, the to-be-operated item information corresponding to the global transaction information cannot be consumed, so that the problem that the final data cannot keep consistency due to the change of part of the to-be-operated item information in the storage process is solved.
In the storage process, one possible storage mode is as follows: when it is monitored that the feedback operation of all second transaction servers participating in the transaction is completed, storing the to-be-operated item information fed back by all second transaction servers corresponding to the global transaction information into a message queue according to a locking state; specifically, when all the second transaction servers participating in the transaction complete the feedback, at this time, the central server stores the to-be-operated item information fed back by all the second transaction servers to the message queue according to the locking state, so that the central server is prevented from executing multiple storage operations, the storage efficiency is improved, and the consistency and concurrency of the to-be-operated item information corresponding to the global transaction information in the storage process are ensured.
Another possible storage manner is: and when the feedback operation of the current second transaction server is monitored to be completed, storing the to-be-operated item information fed back by the current second transaction server corresponding to the global transaction information into a message queue according to a locking state. Specifically, when the central server listens to the feedback operation of the current second transaction server in the plurality of second transaction servers participating in the transaction, directly storing the information of the to-be-operated items fed back by the current second transaction server corresponding to the global transaction information into a message queue according to a locking state without waiting, that is, the central server directly stores the information of the to-be-operated items fed back by the second transaction server according to the first-come first-serve principle, the storage mode avoids the resource waste caused by the waiting process of the central server, meanwhile, when the to-be-operated item information fed back by a certain second transaction server needs to be changed, the first-come first-processing principle also avoids processing all the to-be-operated item information corresponding to the global transaction information, and only the to-be-operated item information needing to be changed needs to be searched in the message queue, so that various processing requirements are met.
It should be noted that the specific storage process of the to-be-operated item information may be set according to actual requirements, and this is not limited in the embodiment of the present invention.
Step S208, when it is monitored that the execution state of the transaction executed by the first transaction server is successful, processing the to-be-operated item information corresponding to the global transaction information in the storage server.
Specifically, after the storing is completed, when the central server monitors that the execution state of the transaction initiator, that is, the first transaction server, for executing the transaction is successful, and if the execution state of the first transaction server, after executing the local operation corresponding to the transaction, is successful, the central server processes the to-be-operated item information corresponding to the global transaction information in the message queue according to the execution state, so that the to-be-operated item information of each transaction participant is separately stored in the message queue, and is uniformly processed after the transaction initiator completes the local operation, thereby avoiding the problem of dirty reading in the distributed transaction processing process.
Compared with the existing transaction servers which respectively process the transaction information, the distributed transaction processing method provided by the embodiment of the invention stores the transaction information corresponding to the transaction into the storage server by storing the transaction information corresponding to the transaction into the storage server, and simultaneously processes the transaction information in the storage server when the execution state of the first transaction server is monitored to be successful, avoids dirty reading in the processing process and realizes the consistency and concurrency of data in the distributed transaction processing process, the processing efficiency of the distributed transaction is improved.
Optionally, after the information of the to-be-operated item corresponding to the global transaction information is stored in the storage server, the method further includes: when the storage operation of the to-be-operated item information corresponding to the global transaction information is monitored to be completed, a storage completion identifier is generated; and sending the storage completion identifier to the first transaction server to trigger the first transaction server to execute the transaction according to the global transaction information. Specifically, after the central server completes storage of all pieces of to-be-operated transaction information corresponding to the global transaction information, a storage completion identifier is further generated, so that a transaction initiator, that is, a first transaction server, is triggered to start executing a local operation corresponding to a transaction through the storage completion identifier, and the to-be-operated transaction information in the message queue is processed according to an execution state.
On the basis of fig. 2, another distributed transaction processing method is further provided in the embodiments of the present invention, where an execution subject is a central server, and the method mainly describes a process of processing to-be-operated item information corresponding to global transaction information in a storage server according to an execution state. As shown in fig. 4, the method comprises the steps of:
step S402, responding to the transaction initiation request of the first transaction server, and generating global transaction information for the transaction corresponding to the transaction initiation request;
step S404, global transaction information is distributed to a second transaction server participating in the transaction through the first transaction server, so that the second transaction server feeds back to-be-operated item information corresponding to the transaction according to the global transaction information;
step S406, storing the to-be-operated item information corresponding to the global transaction information to a storage server;
step S408, monitoring the execution state of the first transaction server for executing the transaction;
the aforementioned method embodiments can be referred to in the aforementioned steps S402 to S408, and the embodiments of the present invention are not described in detail herein.
Step S410, judging whether the execution state is the execution success state; if so, go to step S412; otherwise, step S414 is executed.
Step S412, generating change instruction information, and sending the change instruction information to a storage server, so that the storage server changes the to-be-operated item information corresponding to the global transaction information from a locking state to an unlocking state according to the change instruction information;
specifically, when the central server monitors that the local operation executed by the transaction initiator, that is, the first transaction server, is successful, the central server generates change instruction information at this time to change the to-be-operated item information corresponding to the global transaction information in the message queue from the locked state to the unlocked state, where the unlocked state may also be referred to as a consumption state, so as to execute the to-be-operated item information corresponding to the global transaction information in the message queue, for example, a distributed sub-transaction in each to-be-operated item information is processed according to the corresponding operation information, where the operation information includes a change operation, an add operation, a delete operation, a commit operation, and the like, and may be specifically set according to an actual situation.
Therefore, the to-be-operated transaction information corresponding to the global transaction information is stored in the message queue and is simultaneously processed, so that the dirty reading phenomenon in the distributed transaction processing process is avoided, the consistency and concurrency of data in the distributed transaction processing process are realized, and the processing efficiency of the distributed transaction is improved.
And step S414, generating deletion instruction information, and sending the deletion instruction information to the storage server, so that the storage server deletes the to-be-operated item information corresponding to the global transaction information according to the deletion instruction information.
In addition, when the central server monitors that the local operation executed by the transaction initiator, namely the first transaction server, fails, the transaction execution fails, the to-be-operated item information of each corresponding transaction participant does not need to be executed, namely, the central server generates deletion instruction information to delete the to-be-operated item information corresponding to the global transaction information in the message queue, so that the situation of resource waste caused by too much useless to-be-operated item information stored in the message queue is avoided, and the storage space of the message queue is saved.
Optionally, on the basis of the foregoing method embodiment, another distributed transaction processing method is further provided in the embodiments of the present invention, where an execution subject is a distributed transaction processing system, where the distributed transaction processing system includes a transaction coordinator (i.e., a central server), and a transaction initiator (i.e., a first transaction server), a transaction participant (i.e., a second transaction server), and a storage server configured with a message queue, which are respectively connected to the transaction coordinator, and as shown in fig. 5, the method includes the following steps:
step S502, the transaction initiating side sends a transaction initiating request to the transaction coordinating side;
step S504, the transaction coordinator distributes global transaction information for the transaction corresponding to the transaction initiation request; for example, global transaction information is generated for a transaction corresponding to a transaction initiation request, or global transaction information is allocated for the transaction corresponding to the transaction initiation request from a pre-stored global transaction information set;
step S506, the transaction coordinator sends the global transaction information to the transaction initiator;
step S508, the transaction initiator distributes the global transaction information to the transaction participants participating in the transaction; the number of the transaction participants can be set according to actual conditions, and only one transaction participant is shown in the embodiment of the invention;
step S510, the transaction participant generates corresponding to-be-operated item information according to the global transaction information; if the transaction participant determines the distributed sub-transactions in the transaction corresponding to the transaction initiation request and the operation information corresponding to the distributed sub-transactions according to the global transaction information, and the distributed sub-transactions and the operation information form the to-be-operated item information corresponding to the global transaction information;
step S512, the transaction participant feeds back the information of the to-be-operated items corresponding to the global transaction information to the transaction coordinator;
step S514, the transaction coordinator stores the information of the to-be-operated items corresponding to the global transaction information into a message queue;
step S516, the transaction coordinator generates a storage completion identifier; when the information of the to-be-operated items corresponding to the global transaction information is completely stored, the transaction coordinator generates a storage completion identifier;
step S518, the transaction coordinator sends the storage completion identifier to the transaction initiator;
