MySQL Daniel Dingqi: Distributed Database Technology and Implementation

With the rapid growth of data volume, relational databases have gradually exposed some limitations, such as database access speed and scalability. In recent years, distributed database technology has also developed rapidly, and traditional relational databases have begun to change from centralized The model is developing towards a distributed architecture. Relational distributed databases, while retaining the data model and basic characteristics of traditional databases, move from centralized storage to distributed storage, and from centralized computing to distributed computing.
