Problems solved by technology

[0007] If the distributed system does not support the transactional access method, errors may occur due to operations on consumer accounts or merchant accounts inserted between the above operations, for example, there may be payment loopholes where consumers use the same money to purchase multiple times
How to support transactional access in distributed databases, there is no effective solution for related technologies

Abstract

The invention discloses a distributed database system and a transaction processing method; a storage layer, including at least two storage servers, used for partitioning and distributing data in at least two servers for storage; an access layer, used for receiving transactions initiated by users , to request the lock service layer to lock the target data that needs to be accessed by transactions stored in the storage layer; the lock service layer is used to determine whether the target data is in a locked state according to the lock record of the data in the maintained storage layer, and respond to the lock of the transaction on the target data Request, or block the transaction's lock request for the target data, and store it in the queue corresponding to the target data for queuing. Implementing the present invention can support and realize transactional access mode in the distributed database.

Description

technical field [0001] The invention relates to database technology, in particular to a distributed database system and a transaction processing method. Background technique [0002] A traditional relational database is a database based on a relational model. In order to support data connection (join) processing, the same data has to be stored in a server, which is not conducive to the dispersion of data and the writing of large data. [0003] With the rise of Internet WEB 2.0 websites, traditional relational databases are applied to WEB websites, especially WEB2.0 pure dynamic websites with ultra-large-scale and high-concurrency social relationship network (SNS) have become incapable, exposing many insurmountable problems. question. [0004] Distributed databases, including distributed relational databases and distributed non-relational databases (NoSQL), have developed very rapidly due to their own characteristics. [0005] For example, non-relational databases do not su...
