In general, distributed transaction system includes multiple issued transaction nodes, distributed transaction system passes through each office The processing that node carries out distributed transaction is managed, issued transaction node can both generate business when handling corresponding distributed transaction Data can also generate transaction journal information.The thought of this specification embodiment is, when handling distributed transaction, office Node is managed by the service database of write-in distributed transaction system of transaction journal information caused by it, in this way, avoiding tune With the log database for being set to remote service end, network link when store transaction log information is shortened, to reduce The storage of transaction journal information is time-consuming, improves the storage efficiency of transaction journal information.Based on this, this specification embodiment is provided A kind of storage method, device, equipment and the storage medium of distributed transaction log, it is following to be introduced in detail one by one.

It should be noted that the storage method for the distributed transaction log that this specification embodiment provides is applied to distribution Issued transaction node in transaction system, the i.e. executing subject of this method are issued transaction node, specifically, can be to be set to The storage device of the distributed transaction log of issued transaction node.

Fig. 1 is one of the method flow diagram of storage method for the distributed transaction log that this specification embodiment provides, Fig. 1 Shown in method include at least following steps:

Step 102, issued transaction node obtains transaction journal information corresponding to the distributed transaction of its processing；Wherein, Above-mentioned issued transaction node is the node in distributed transaction system.

In general, the processing of distributed transaction can be divided into two stages, respectively preparation stage and operational phase, In, the preparation stage is that the execution of operational phase is laid the groundwork.In this specification embodiment, it is mentioned to transaction journal information then produce The raw preparation stage in distributed transaction.

For example, being transferred accounts to Li Si for 20 yuan by Zhang San, which can be divided into preparation stage and operational phase, Operation corresponding to preparation stage is then whether the account for inquiring Zhang San has 20 yuan, and freezes the account of Zhang San, and inquiry Lee Four account whether there is, and lock the account of Li Si, if the preparation stage prepares to operate, then execute the transfer operation stage. For this distributed transaction, then transaction journal information is then generated " whether the account of inquiry Zhang San has 20 yuan, and freezes Zhang San's Account, the account for inquiring Li Si whether there is, and lock the account of Li Si " during this.

In general, each stage of each distributed transaction can be divided into multiple subtransactions, an issued transaction node For handling one of subtransaction.

For example, continuing to use the example above, Zhang San transfers accounts 20 yuan to Li Si, wherein for operation performed by the preparation stage, " whether the account of inquiry Zhang San has 20 yuan, and freezes the account of Zhang San " then belongs to a subtransaction, by an issued transaction Node executes, and " account of inquiry Li Si whether there is, and lock the account of Li Si " belongs to a subtransaction, by an office Node is managed to execute.

Therefore, in above-mentioned steps 102, distributed transaction handled by issued transaction node can be understood as the issued transaction Subtransaction in distributed transaction to be processed needed for node.Each issued transaction node is handling corresponding distributed transaction When, corresponding transaction journal information can be generated, the transaction journal information is for recording distribution handled by the issued transaction node Formula affair related information and the issued transaction node related information.I.e. in the specific implementation, above-mentioned transaction journal information can be with For the information of which affairs of which issued transaction node processing.For example, above-mentioned transaction journal information, which can be, executes the distribution Transaction identification information handled by the identification information of the issued transaction node of affairs, the issued transaction node etc..

In this specification embodiment, above-mentioned issued transaction node obtains thing corresponding to the distributed transaction handled by it Business log information, can be the process for reading transaction journal information from the issued transaction node, is also possible to the issued transaction section Point generate transaction journal information process, this specification embodiment not to the detailed process of above-mentioned acquisition transaction journal information into Row limits.

Step 104, issued transaction node is by the business of the transaction journal information write-in distributed transaction system corresponding to it In database；Wherein, above-mentioned business datum lab setting is in issued transaction node.

Service database is generally used for store transaction processing node generated industry when handling corresponding distributed transaction Business data, when each issued transaction node belongs to different application programs, then each issued transaction node is set in own node It is equipped with corresponding service database, for storing transaction journal caused by the service processing node；Belong to same application domain Issued transaction node correspond to the same service database.In this specification embodiment, in order to reduce transaction journal information Storage is time-consuming, then transaction journal information caused by it also is stored in service database by issued transaction node.

In addition, it is necessary to explanation, each issued transaction section in this specification embodiment, in distributed transaction system Point the transaction journal information corresponding to it can be written in the service database corresponding to it, be also possible at partial transaction Transaction journal information corresponding to it is written in the service database corresponding to it reason node.

In the specific implementation, if each issued transaction node is provided with corresponding service database in own node, then In above-mentioned steps 104, issued transaction node is by the business number of the transaction journal information write-in distributed transaction system corresponding to it According in library, specifically include:

Transaction journal information corresponding to it is written in the service database corresponding to it issued transaction node；Wherein, Business datum lab setting corresponding to issued transaction node is in the issued transaction node.

It i.e. in this embodiment, then is that its corresponding transaction journal information write-in is arranged each issued transaction node In the service database on own node.

For example, distributed transaction system includes issued transaction node 1, issued transaction node 2 and issued transaction node 3 three Issued transaction node, transaction journal information corresponding to issued transaction node 1 are denoted as transaction journal information 1, issued transaction node 2 Corresponding transaction journal information is denoted as transaction journal information 2, and transaction journal information corresponding to issued transaction node 3 is denoted as thing Business log information 3, when carrying out the storage of transaction journal information, the write-in of transaction journal information 1 is set to by issued transaction node 1 In the service database 1 of issued transaction node 1, the write-in of transaction journal information 2 is set to issued transaction section by issued transaction node 2 In the service database 2 of point 2, the business for being set to issued transaction node 3 is written in transaction journal information 3 by issued transaction node 3 In database 3.In this way, each issued transaction node is when carrying out the storage of corresponding transaction journal information, it is only necessary to which calling is set It is placed in the service database of the issued transaction node, avoids the transaction journal data called and be set to remote service end Library shortens the network link of store transaction log information, and the write-in for reducing transaction journal information is time-consuming, improves affairs day The write efficiency of will information, and then improve the new energy of distributed transaction system.

It certainly, is then that each issued transaction node in a distributed manner in transaction system is corresponding by its in the example above Transaction journal information is written for its corresponding service database, in addition to this, can be issued transaction node 1, issued transaction Node 2 writes its corresponding transaction journal information with any one or the two issued transaction nodes in issued transaction node 3 Enter service database, remaining issued transaction node then continues the issued transaction node write-in corresponding to it being set to long-range clothes It is engaged in the transaction journal database at end.Service database is not written to by transaction journal information in this specification embodiment The quantity of issued transaction node is defined.

In general, above-mentioned issued transaction node includes master transaction processing node and subtransaction processing node；Master transaction processing Node is generally the initiation node of the affairs.

Therefore, in some embodiments, in above-mentioned steps 104, issued transaction node is by the transaction journal corresponding to it Information is written in the service database of distributed transaction system, can also be realized by following process:

Issued transaction node is by business number corresponding to the transaction journal information write-in master transaction processing node corresponding to it According in library；Wherein, business datum lab setting corresponding to master transaction processing node handles node in master transaction.
