Distributed transaction processing system using multi-type replica in decentralized schema

Abstract

The invention discloses a distributed transaction processing system using a multi-type replica in a decentralized schema. The distributed transaction processing system comprises a transaction interface module, a transaction processing module and a transaction memory module, wherein the transaction interface module comprises an outward interface sub-module and a transaction preprocessing sub-module, the transaction processing module comprises a multi-type replica sub-module, a read transaction processing module, a replica group transaction state sub-module, a read request distribution sub-module, a replica repair sub-module, a multiversion concurrency control (MVCC) read sub-module, a local writing transaction processing sub-module, a local writing transaction paxos replica consistency sub-module, a local writing transaction commit sub-module, a global writing transaction processing sub-module, a main sub-transaction paxos replica consistency sub-module, a secondary sub-transaction paxos replica consistency sub-module and a global writing transaction commit sub-module. The distributed transaction processing system can solve the problems in an existing system that the reading and writing environment is limited, reading and writing availability can not be configured autonomously according to requirements of application, a global transaction depends on locking and cost is high.

Description

technical field [0001] The invention belongs to the technical field of distributed storage, and more specifically relates to a distributed transaction processing system using multiple types of copies in a decentralized architecture. Background technique [0002] With the continuous development of Internet technology, the data in the Internet is rising at an incredible speed. How to store and process such large-scale data has become the research direction of today's big data era. Decentralized NoSQL is a large-scale data storage system with the following characteristics: high read and write performance, no single point of failure, high availability, and high scalability. For example, the Cassandra system uses a column family-oriented storage model to achieve high read and write performance, uses a decentralized architecture to avoid single points of failure and achieve high availability, and uses consistent hashing to achieve high scalability. [0003] The distributed transa...
