Problems solved by technology

However, in order to meet the requirements of distributed transaction processing, each transaction coordinator in a distributed transaction processing system usually adopts a distributed setting. Each transaction coordinator is limited by writing data to a storage device, and it is often difficult to Distributed expansion is required, which limits the scalability of the distributed transaction processing system, which in turn affects the processing efficiency of distributed transactions

Abstract

The invention provides a distributed transaction processing method and device, which are based on a distributed transaction processing system, the distributed transaction processing system comprises aplurality of memories, and any one of the memories corresponds to a unique transaction coordinator. As the transaction coordinators are in one-to-one correspondence with the memories, the transactiondata obtained by the target transaction coordinators are written into the memories corresponding to the target transaction coordinators. And if submission or rollback needs to be initiated to each branch corresponding to the transaction processing request in subsequent steps, the submission or rollback can be realized only based on the transaction data in the memory, and the data in other memories except the target memory does not need to be called. When the data processing capability of the distributed transaction processing system is excessive, a transaction coordinator and a memory accessed to the distributed transaction processing system can be properly reduced. The distributed transaction processing system in the specification has relatively high expandability and flexibility.

Description

technical field [0001] The present application relates to the technical field of distributed transaction processing, and in particular, the present application relates to a distributed transaction processing method and device. Background technique [0002] A transaction is the smallest logical unit of work for an operation sequence to access a database for specific business functions. A distributed transaction means that a transaction may involve multiple database operations. [0003] Usually, after a distributed transaction processing system receives a transaction processing request, it will process the transaction corresponding to the transaction processing request according to preset business rules, and generate various data during the processing, for example, log data. Afterwards, various data generated by the distributed transaction processing system are stored in storage devices for use in subsequent steps. However, in order to meet the requirements of distributed t...
